Purpose: We investigated the anti-adhesive effects of a temperature-sensitive poloxamer/alginate mixture (Guardix-SG®; Hanmi Medicare Inc., Korea) through a prospective randomized controlled study for carpal tunnel release surgery. Methods: The 47 patients who received the infusion were classified as Group 1, and the 51 patients who did not were classified as Group 2. Basic demographic factors and preoperative clinical status were evaluated. At the postoperative 18 months, the degree of clinical recovery and adhesion around the median nerve for both groups were evaluated and compared using sonography. Results: The clinical outcomes, which were assessed using the six-item carpal tunnel symptoms scale, were not significantly different between the groups. However, sonography showed that adhesions around the median nerve were significantly less common in the infusion group. Conclusion: Although the anti-adhesive effects of the temperature-sensitive Guardix-SG® were apparent upon radiological investigation, its use was not associated with a significant difference in clinical outcome on the short-term period follow-up.

Background: DeQuervain tenosynovitis, refractory to medical conservative treatment, has been traditionally treated by a simple division of the pulley, a procedure associated with several complications. Many authors attempted to prevent these complications by describing techniques of pulley reconstruction after its release necessitating suturing the different flaps and subsequently promoting extensor tendons adhesions. The authors present an alternative procedure for the first extensor compartment pulley decompression: 'Omegaplasty'. Methods: 25 Patients with 29 DeQuervain tenosynovitis cases were enrolled in a prospective, nonrandomized clinical trial from 2012 to 2016. At enrollment they were offered the option of Omegaplasty as a surgical treatment modality for their cases. The procedure is based on liberating the anterior attachment of the pulley from the anterior lip of the styloïd process while respecting its continuity with the periosteal flap as well as promoting expansion of the tunnel volume. All operated patients were evaluated using the 'Opposition Kapandji Score'. Results: The authors present the results of 29 different 'Omegaplasty' procedures. Based on the Kapandji opposition score, twenty cases scored 10/10 while the remaining nine cases yielded an 8/10 score each. Conclusions: The described technique is simple, reliable and respects the extensor tendons gliding physiology and biodynamics. By preserving the anatomical continuity of the first extensor compartment pulley at the wrist, the risk of adhesion formation is reduced. The preliminary results are encouraging and provide the 'Ω' plasty the potential to be considered as a surgical option for treatment of De Quervain Tenosynovitis. [ABSTRACT FROM AUTHOR]

Aberrant Muscle Syndrome (AMS) is a rare congenital hand difference that is characterised by unilateral non-progressive muscular hyperplasia. The aetiology of aberrant muscle syndrome is not known, but a recently published case has shown a somatic PIK3CA activating mutation in a patient with AMS. Carpal tunnel syndrome (CTS) in children is rare. The most common causes are the mucopolysaccaridoses but space-occupying lesions have also been reported to cause CTS in children. We report the first case of CTS in a child with AMS successfully treated with open carpal tunnel release and excision of aberrant muscles. [ABSTRACT FROM AUTHOR]

We report a case of bilateral carpal tunnel syndrome (CTS) with bilateral bifid median nerve (BMN) without a persistent median artery diagnosed by clinical examination, NCV and Ultrasonography. Bilateral BMN to produce bilateral CTS is extremely rare and is contrary to the popular classifications which state that BMN without persistent median artery or its anomalies will not produce CTS. Ultrasonogram is of additional help to identify such aberrations in the median nerve to prevent iatrogenic injuries during carpal tunnel decompression. [ABSTRACT FROM AUTHOR]

Introduction: Higher quality care for carpal tunnel syndrome (CTS) may be associated with better outcomes.Methods: This prospective observational study recruited adults diagnosed with CTS from 30 occupational health centers, evaluated physicians' adherence to recommended care processes, and assessed results of the Boston Carpal Tunnel Questionnaire (BCTQ) and Short Form Health Survey version 2 (SF-12v2) at recruitment and at 18 months.Results: Among 343 individuals, receiving better care (80th vs. 20th percentile for adherence) was associated with greater improvements in BCTQ Symptom Severity scores (-0.18, 95% confidence interval [CI] -0.32 to -0.05), BCTQ Functional Status scores (-0.21, 95% CI -0.34 to -0.08), and SF12-v2 Physical Component scores (1.75, 95% CI 0.33-3.16). Symptoms improved more when physicians assessed and managed activity, patients underwent necessary surgery, and employers adjusted job tasks.Discussion: Efforts should be made to ensure that patients with CTS receive essential care processes including necessary surgery and activity assessment and management.

The aim of this study was to investigate the effects of current physical activity levels on pain in patients included in a physical therapy program for various musculoskeletal diseases. The data were collected from 250 patients aged 35 to 65 years who were included in a physical therapy program, and diagnosed as cervical or lumbar spondylosis, lumbar or cervical herniated nucleus pulposus, carpal tunnel syndrome and gonarthrosis, Pain was assessed with visual analog scale (VAS) and physical activity was measured with a Physical Activity Assessment Questionnaire (PAAQ) and categorized based on metabolic equivalent value minutes per week (MET, min/weeks). Our results showed that physical activity levels were low in the majority of the cases and it was found that physical activity levels had no effect on pain. Male patients consumed more energy at workplace while female patients spent more energy in the household. It was found that gonarthrosis, obesity, being retirement or a housewife, and advanced age had negative effect on physical activity levels. Patients' physical activity levels must be increased without arising pain and weight control should be implemented. [ABSTRACT FROM AUTHOR]

Background:Carpal tunnel syndrome (CTS) and trigger digits are among the most common nontraumatic hand disorders treated by plastic surgeons. The onset of trigger digits after carpal tunnel release (CTR) has been inconsistently reported. This systematic review assessed the prevalence of trigger digits development in patients after CTR surgery. Methods:We searched the MEDLINE, EMBASE and SCOPUS databases for papers published between January 1966 and August 2016. Eligible studies contained quantitative data on the incidence of trigger digits after CTR. The primary outcome measure was the onset of trigger digits after CTR. The secondary outcome measure was the prevalence of digital involvement in patients who developed trigger digits after CTR. Results:A total of 5654 CTR surgeries were performed in the included nine studies, and 483 patients (8.5%) developed trigger digits after CTR. The reported incidence of trigger digits after CTR ranged from 5.2% to 31.7%. The time to development of trigger digits was approximately 6 months postoperatively. In the eight observational studies and in the randomized controlled trial, the thumb and ring finger were reported as the most commonly involved trigger digits, respectively. Conclusions:The incidence of trigger digits after CTR surgery is not negligible. Thumbs and ring fingers are the most commonly involved digits. This topic should therefore be suitably addressed during preoperative consultations. [ABSTRACT FROM AUTHOR]

Aim: In this study, we aimed to determine the efficacy of splinting and exercise modalities in addition to surgical treatment in advanced carpal tunnel syndrome (CTS) cases. Material and Method: Patients were divided into 3 different groups according to the order of application, and after surgical intervention their treatment was continued according to the group they were in. There were 51 hands in 50 female patients in group 1 (control group); 52 hands in 51 female patients in group 2 (exercise group); 52 hands in 50 patients in group 3 (wrist splint group). Patients were given a follow-up number by computer software under which the following data were recorded: age, body mass index (BMI), date of surgery, operated side, preoperative disorders, pre and postoperative EMG findings, surgical technique, pre and postoperative visual analogue scales (VAS), pre and post-operative Boston Carpal Tunnel Questionnaire (BCTQ) and post-operative complications. Kolmogorov-Smirnov test and Spearman's rho correlation coefficient (r) were used for statistical analysis. Results: There was no statistical difference between the groups in terms of VAS and FSS change. However, there was a statistically significant difference in terms of BSSS change. In the exercise group (Group 2) it was found that the healing was better and faster than the other groups. Conclusion: We believe that early and effective postoperative exercise, which is to be applied in addition to surgical treatment in advanced CTS cases, leads to healing of the patient and, in parallel, early return to work.

Background: Health literacy is the ability to obtain, process, and understand health information needed to make appropriate health decisions. The proper comprehension by patients regarding a given disease, its treatment, and the physician's instructions plays an important role in shared decision-making. Studies have disagreed over the degree to which differences in health literacy affect patients' preferences for shared decision-making; we therefore sought to evaluate this in the context of shared decision-making about carpal tunnel release.Questions/purposes: (1) Do patients with limited health literacy have different preferences of shared decision-making for carpal tunnel release than those with greater levels of health literacy? (2) How do patients with limited health literacy retrospectively perceive their role in shared decision-making after carpal tunnel release?Methods: Over a 32-month period, one surgeon surgically treated 149 patients for carpal tunnel syndrome. Patients were eligible if they had cognitive and language function to provide informed consent and complete a self-reported questionnaire and were not eligible if they had nerve entrapment other than carpal tunnel release or had workers compensation issues; based on those, 140 (94%) were approached for study. Of those, seven (5%) were lost to followup before 6 months, leaving 133 for analysis here. Their mean age was 55 years (range, 31-76 years), and 83% (111 of 133) were women. Thirty-three percent (44 of 133) of patients had less than a high school education. Health literacy was measured according to the Newest Vital Sign during the initial visit, and a score of ≤ 3 was considered limited health literacy. Forty-four percent of patients had limited health literacy. The Control Preferences Scale was used for patients to indicate their preferred role in surgical decision-making preoperatively and to assess their perceived level of involvement postoperatively. Bivariate and multivariable analyses were performed to determine whether patients' clinical, demographic, and health literacy factors accounted for the preoperative preferences and postoperative assessments of their role in shared decision-making. A total of 133 patients would provide 94% power for a medium effect size for linear regression with five main predictors.Results: We found no differences between patients with lower levels of health literacy and those with greater health literacy in terms of preferences of shared decision-making for carpal tunnel release (3.0 ± 1.6 versus 2.7 ± 1.4; mean difference, 0.3; 95% confidence interval, -0.2 to 0.8; p = 0.25). A history of surgical procedures (coefficient = -0.32, p < 0.01) and a lower Disabilities of the Arm, Shoulder and Hand score (coefficient = 0.17, p = 0.02) were independently associated with a preference for an active role in shared decision-making. However, patients with limited health literacy (coefficient = -0.31, p = 0.01) and an absence of a caregiver (coefficient = -0.28, p = 0.03) perceived a more passive role in actual decision-making.Conclusions: Physicians should be aware of the discrepancy between preferences and perceptions of shared decision-making among patients with limited health literacy, and physicians should consider providing a decision aid tailored to basic levels of health literacy to help patients achieve their preferred role in decision-making.Level Of Evidence: Level II, prognostic study.

Background: Postoperative pillar pain (deep-seated wrist pain worsened by leaning on the heel of the hand) sometimes occurs after carpal tunnel release (CTR), leading to weakness in the hand and delayed return to work. Increased pain sensitivity has been found to be associated with worse symptoms and poorer treatment response in a number of chronic musculoskeletal conditions, but few studies have investigated the association of pain sensitization with pillar pain after CTR.Questions/purposes: (1) Is preoperative pain sensitization in patients with carpal tunnel syndrome (CTS) associated with increased severity of pillar pain after open CTR? (2) What other demographic, electrophysiological, or preoperative clinical characteristics are associated with pillar pain after CTR?Methods: Over a 35-month period, one surgeon performed 162 open carpal tunnel releases. Patients were eligible if they had sufficient cognitive and language function to provide informed consent and completed a self-reported questionnaire; they were not eligible if they had nerve entrapment other than CTR or if the surgery was covered by workers compensation insurance. Based on these criteria, 148 (91%) were approached for this study. Of those, 17 (9%) were lost to followup before 12 months, leaving 131 for analysis. Their mean age was 54 years (range, 32-78 years), and 81% (106 of 131) were women; 34% (45 of 131) had less than a high school education. We preoperatively measured pain sensitization by assessing the patients' pressure pain thresholds by stimulating pressure-induced pain in the pain-free volar forearm and administering a self-reported Pain Sensitivity Questionnaire minor subscale, an instrument that assesses pain intensity in daily life situations. We evaluated postoperative pillar pain using the "table test" (having the patient lean on a table with their weight on their hands placed on the table's edge with elbows straight) with an 11-point ordinal scale at 3, 6, and 12 months after their surgical procedures. We conducted bivariate and multivariable analyses to determine whether the patients' clinical, demographic, and pain sensitization factors were associated with their postoperative pillar pain severity after CTR.Results: After controlling for relevant confounding variables such as age, education level, and functional states, we found that increased pillar pain severity was associated with the pressure pain threshold (β = -1.02 [-1.43 to -0.61], partial R = 11%, p = 0.021) and Pain Sensitivity Questionnaire minor (β = 1.22 [0.73-1.71], partial R = 17%, p = 0.013) at 3 months, but by 6 months, only Pain Sensitivity Questionnaire minor (β = 0.92 [0.63-1.21], partial R = 13%, p = 0.018) remained an associated variable for pillar pain. Additionally, gender (women) was associated with increased pain severity at 3 (β = 0.78 [0.52-1.04], partial R = 9%, p = 0.023) and 6 months (β = 0.72 [0.41-1.01], partial R = 8%, p = 0.027). At 3 months, pressure pain threshold, Pain Sensitivity Questionnaire minor, and gender (women) collectively accounted for 37% of the variance in pillar pain severity; at 6 months, Pain Sensitivity Questionnaire minor and gender (women) accounted for 21% of the variance, but no relationship between those factors and pillar pain was observed at 12 months.Conclusions: Gender (women) and preoperative pain sensitization measured by pressure pain threshold and self-reported Pain Sensitivity Questionnaire were associated with pillar pain severity up to 3 and 6 months after CTR, respectively. However, the influence of pain sensitization on pillar pain was diminished at 6 months and it did not show persistent effects beyond 12 months. Pain sensitization seems to be more important in the context of recovery from surgical intervention (in the presence of a pain condition) than in healthy states, and clinicians should understand the role of pain sensitization in the postoperative management of CTS. Future research may be needed to determine if therapeutic interventions to reduce sensitization will decrease the risk of pillar pain.Level Of Evidence: Level III, prognostic study.

Background: Some long-term hemodialysis patients suffer from multi-recurrent carpal tunnel syndrome because amyloid originating from β2-microglobulin continues to be deposited mainly in the flexor tendons, tendon sheaths and flexor retinaculum during maintenance hemodialysis. These amyloid deposits inside carpal canal (tunnel) tissues increase carpal canal pressure and this leads to compression of the median nerve. When multi-recurrent carpal tunnel syndrome occurs, previous operative scarring of soft tissue may prohibit further enlargement of the carpal canal even if any carpal canal decompression procedure is used. For this reason, we developed a median nerve anterior transposition procedure, as a new approach in the treatment of multi-recurrent hemodialysis-related carpal tunnel syndrome. Methods: Median nerve anterior transposition procedures were performed on seven hands in six patients with multi-recurrent carpal tunnel syndrome. The mean age of the patients was 68.3 years and the mean hemodialysis duration was 35.3 years. Mean follow-up period was 9.9 months. The median nerve is transposed from inside to outside of the carpal canal under local and infiltration anesthesia without a pneumatic tourniquet on an outpatient basis. This procedure is based on the same principles applied in ulnar nerve anterior transposition procedures for cubital tunnel syndrome. Results: Main preoperative patient complaints were intolerable tingling and/or pain in the diseased hands throughout the day. Following the surgeries, preoperative clinical symptoms began to subside and eventually improved in all hands. Postoperative abductor pollicis brevis muscle power using manual muscle testing improved except in one hand. Abnormal preoperative distal motor and sensory latency were improved except in two hands following the surgeries. Conclusions: The median nerve anterior transposition procedure is a beneficial treatment for patients suffering from hemodialysis-related multi-recurrent carpal tunnel syndrome.

In this article, we report two cases in which recurrent adhesive hand neuropathy with allodynia were successfully treated with radial and ulnar artery adipofascial perforator flap coverage. Treatment of recurrent neuropathy, such as recurrent carpal tunnel syndrome and re-adhesion after neurolysis using free and pedicle flaps to cover the nerves, has been reported to show good results. However, for severe painful nerve disorders, such as complex regional pain syndrome, the efficacy of this treatment was unclear. We present two cases diagnosed with recurrent adhesive hand neuropathy with allodynia, resulting from wrist cutting; these cases were treated with neurolysis and flap coverage with good results and no recurrence. This suggests that neurolysis and flap coverage are effective methods for treating complex regional pain syndrome. [ABSTRACT FROM AUTHOR]

Objectives: To quantitatively assess carpal tunnel syndrome (CTS) with DTI by evaluating two approaches to determine cut-off values.Methods: In forty patients with CTS diagnosis confirmed by nerve conduction studies (NCs) and 14 healthy subjects (mean age 58.54 and 57.8 years), cross-sectional area (CSA), apparent diffusion coefficient (ADC) and fractional anisotropy (FA) at single and multiple levels with intraobserver agreement were evaluated.Results: Maximum and mean CSA and FA showed significant differences between healthy subjects and patients (12.85 mm2 vs. 28.18 mm2, p < 0.001, and 0.613 vs. 0.524, p=0.007, respectively) (10.12 mm2 vs. 19.9 mm2, p<0.001 and 0.617 vs. 0.54, p=0.003, respectively), but not maximum and mean ADC (p > 0.05). For cut-off values, mean and maximum CSA showed the same sensitivity and specificity (93.3 %). However, mean FA showed better sensitivity than maximum FA (82.6 % vs. 73.9 %), but lower specificity (66.7 % vs. 80 %), and significant correlation for maximum CSA, 97 % (p < 0.01), with good correlation for maximum ADC and FA, 84.5 % (p < 0.01) and 62 % (p=0.056), respectively.Conclusions: CSA and FA showed significant differences between healthy subjects and patients. Single measurement at maximum CSA is suitable for FA determination. Key Points • DTI showed that FA is stronger than ADC for CTS diagnosis. • Single- and multiple-level approaches were compared to determine FA and ADC. • Single-level evaluation at the thickest MN cross-sectional area is sufficient.

Objective:The objectives of this survey were (1) to study if surgeons’ perceptions of the benefit of six surgical procedures differ if they consider themselves as patients instead of treating a patient, (2) to evaluate the role of five predetermined factors that may influence decision-making, and (3) to assess how uniformly hand surgeons and hand therapists perceive the benefits of the surgical treatments. Methods:The members of the national societies for Hand Surgery and Hand Therapy were asked to participate in the survey. Six patient cases with hand complaint (carpal tunnel syndrome, flexor tendon injury, dorsal wrist ganglion, thumb amputation, boxer’s fracture, and mallet fracture) and a proposed operative procedure were presented, and the respondents rated the procedures in terms of the expected benefit. Half of the surgeons were advised to consider themselves as patients when filling out the survey. Results:A survey was completed by 56 surgeons (61%) and 59 therapists (20%). Surgeons who considered themselves as patients had less confident perception on the benefit of carpal tunnel release compared with surgeons, who considered treating patients. Hand surgeons and hand therapists had similar perception of the benefits of surgery. The expected functional result was regarded as the most important factor in directing the decision about the treatment. Conclusions:Surgeons tended to be more unanimous in their opinions in cases, where there is limited evidence on treatment effect. The agreement between surgeons and therapists implies that the clinical perspectives are similar, and probably reflect the reality well. [ABSTRACT FROM PUBLISHER]

Objective To investigate the diagnostic value of cross-sectional area (CSA) and wrist to forearm ratio (WFR) in patients with electro-diagnosed carpal tunnel syndrome (CTS) with or without diabetes mellitus (DM). Methods We retrospectively studied 256 CTS wrists and 77 healthy wrists in a single center between January 1, 2008 and January 1, 2013. The CSA and WFR were calculated for each wrist. Patients were classified into four groups according to the presence of DM and CTS: group 1, non-DM and non-CTS patients; group 2, non-DM and CTS patients; group 3, DM and non-CTS patients; and group 4, DM and CTS patients. To determine the optimal cut-off value, receiver operating characteristic (ROC) curve analysis was performed. Results The CSA and WFR were significantly different among the groups (p<0.001). The ROC curve analysis of non-DM patients revealed CSA =10.0 mm² and WFR =1.52 as the most powerful diagnostic values of CTS. The ROC curve analysis revealed CSA =12.5 mm² and WFR =1.87 as the most powerful diagnostic values of CTS. Conclusion Ultrasonographic assessment for the diagnosis of CTS requires a particular cut-off value for diabetic patients. Based on the ROC analysis results, improved accurate diagnosis is possible if WFR can be applied regardless of presence or absence of DM. [ABSTRACT FROM AUTHOR]

Carpal Tunnel Syndrome (CTS) is the most common surgically treated problem in the hand. Aside from the neuropathy itself, the most common findings are fibrosis of the subsynovial connective tissue (SSCT) and increased intra carpal tunnel pressure. Normally, the SSCT is a multilayer tissue interspersed among the carpal tendons and nerve. As the tendons move, successive SSCT layers are recruited, forming a gliding unit and providing a limit to differential movement. Exceeding this limit, damages the SSCT as has been shown in both cadavers and animal models. This damage leads to a non-inflammatory response with progressive fibrosis and nerve ischemia leaving the SSCT more susceptible to injury. Although the direct consequences for patients are not fully understood, ultrasound research shows that this fibrosis restricts median nerve displacement during tendon loading. This article aims to provide insights into the mechanical properties of SSCT described so far and place it in the context of CTS pathophysiology. A theoretical damage model concerning the SSCT is proposed showing a chain of events and vicious cycles that could lead to the nerve compression as it is found in CTS. Although not complete, this model could explain the pathophysiological pathway of idiopathic CTS. [ABSTRACT FROM AUTHOR]

Background: Recent studies have reported that radial extracorporeal shock wave therapy (rESWT) reduces pain and improves function in patients with mild to moderately severe carpal tunnel syndrome (CTS) compared to a placebo. However, most of those studies used multi-session rESWT combined with wrist support and evaluation of efficacy was limited to a maximum of 14 weeks.Methods: The prospective randomized controlled trial compared efficacy in relieving pain and improving clinical function between single-dose rESWT and local corticosteroid injection (LCsI) over the mid-term (24 weeks). Twenty-five patients with mild to moderately severe CTS were randomized to receive either single-dose rESWT (n = 13) or LCsI (n = 12). Primary outcomes were evaluated using the Boston self-assessment questionnaire (BQ), while secondary outcomes used the Visual analogue scale (VAS) and electrodiagnostic parameters. Evaluations at baseline and at 1, 4, 12 and 24 weeks after treatment were performed.Results: There was significantly greater improvement in symptom severity scores, functional scores and Boston questionnaire scores at weeks 12 to 24 in the rESWT group compared to the LCsI group. When compared to the baseline, there was significant reduction of VAS and functional score in the rESWT group at weeks 12 and 24. The LCsI group had no statistically significant differences in VAS reduction and functional score of the same period.Conclusions: Treatment of CTS using single-dose rESWT has a carry-over effect lasting up to 24 weeks suggesting that single-dose rESWT is appropriate for treatment of mild to moderate CTS and provides longer-lasting benefits than LCsI.Trial Registration: ( TCTR20150709001 ).

Context: Carpal tunnel syndrome (CTS) is one of the most common peripheral neuropathies, and there is no consensus on the preferred method of treatment. Aims: The aim of this study is to determine the effects of hand exercise performed with a ball on symptoms and to evaluate the results in hemodialysis (HD) patients with CTS. Settings and Design: This study was conducted in patients with HD who were treated in dialysis centers and state hospitals in Turkey between 2011 and 2012. Subjects and Methods: This study included 19 patients (28 hands) that were diagnosed as CTS. For exercise treatment, a hand and finger exercise ball that consists of two parts: a foam body and flexible rubber cords was used. Patients placed their fingers through each cord, squeezed it for 1 s, and then opened their fingers against the cord for 1 s. Patients repeated this exercise for 30 s to 1 min/day. Statistical Analysis Used: The McNemar, Friedman ANOVA, and the Wilcoxon test with a Bonferroni correction were used on SPSS 20.0 software package program. P < 0.05 was considered statistically significant. Results: Results showed that recovery was performed from physical examination results, grip strength, and Boston questionnaire scores. About 21.4% of patients' electrophysiological results were negative at the end of the 1st month and 32.1% of them at the end of the 3rd month. Conclusion: Due to the slowed progress of CTS and detection of slight improvement in evaluation parameters, this self-applicable and practical exercise can be used as an alternative treatment of mild CTS in patients with HD.

Background: The factors associated with the spontaneous remission (SR) of symptoms in carpal tunnel syndrome (CTS) are not well known. Objectives: To look for determinants of SR in medically treated, electrophysiologically proven patients of CTS. Methods: We revisited the medical records and nerve conduction study data of 130 hands with CTS and divided them into two groups as per the absence or persistence of the symptoms when contacted after a median time lapse of 3 years following the diagnosis. Results: SR occurred in 46.1% of the hands. Higher odds of SR were linked with female gender, symptoms restriction to lateral fingers, symptom duration <10 months, mildly delayed median motor and sensory distal latencies, and median sensory amplitude >20 µV. We developed a seven-point scale, on which a score of ≥4 had a strong association (odds ratio 4.31) with SR. Discussion and Conclusion: No single risk factor, standalone, can predict SR in patients with CTS, which could lead to an invasive treatment (Surgery or local injection) to them. We propose that patients scoring ≥4 on our 7 point scale should be treated medically for the initial 10 months after the symptom onset. [ABSTRACT FROM AUTHOR]

Background: Carpal tunnel syndrome (CTS) is commonly seen in elderly populations, in part due to increased presence of predisposing comorbidities as well as physiological changes. We aimed at comparing the effectiveness of different doses of steroid using the ultrasound- guided hydrodissection method in elderly patients with CTS. Methods: We conducted a prospective, triple-blind, randomized, controlled trial in elderly patients with CTS. Patients were allocated to one of three groups by simplified randomization. Groups I-III received 80 mg triamcinolone (2 mL) and 1 mL of 2% lidocaine; 40 mg triamcinolone (1 mL), 1 mL of 2% lidocaine, and 1 mL normal saline; and 1 mL of 2% lidocaine and 2 mL normal saline, respectively to make up to 3 mL volume. A wrist splint was then applied for support. Outcome measures included the visual analog scale (VAS) and the Boston Carpal Tunnel Questionnaire, and median motor and sensory nerve conduction and its sonographic inlet cross-sectional area were used as objective measures. All data were recorded at baseline and 2, 12, and 24 weeks after injection. The investigators, patients, and statistician were blinded to the treatment assignment. Results: 1n total, 161 patients were recruited without statistically significant demographic differences between the three groups. There were no statistically significant differences between groups in any outcome, with the exception of the median distal motor latency, which was greater in Group II at all three follow-up visits, and significant baseline VAS difference between Groups I and III. Conclusion: Hydrodissection with lidocaine and normal saline is as effective as hydrodissection with low- and high-dose steroid medication in elderly patients with CTS in this study, but further studies with matched baseline measures and also a sham group are suggested for definitive recommendation.

Background and Aim: L-Acetyl-carnitine (LAC) exerts an energetic effect on nerves and muscles. Recently, preclinical experiments have demonstrated a central anti-nociceptive action.Objective: Our objective was to assess the effects of LAC on neuroprotection, pain, and function in carpal tunnel syndrome (CTS), a very frequent chronic compressive neuropathy.Methods: In a multicentre, examiner-blinded, clinical and neurophysiological 4-month study, we enrolled 82 patients and examined 120 hands with CTS of mild to moderate severity. Patients were assessed at baseline and 10, 60 and 120 days after treatment with LAC 500 mg twice daily (BID). All patients underwent a conduction study of the median nerve, the Boston Carpal Tunnel Questionnaire (BCTQ) and the Neuropathic Pain Symptom Inventory (NPSI). The primary endpoint was the sensory conduction velocity (SCV) of the median nerve.Results: The primary endpoint was met, with significant improvement of the SCV (P < 0.0001). All sensory neurophysiological measures also significantly improved. BCTQ score changed significantly (P < 0.0001), with a greater improvement in the symptom component. Nine of the NPSI types of pain, particularly squeezing and pressure pain and pain evoked by pressure, showed a significant reduction (P < 0.0001).Conclusions: Our clinical and neurophysiological study indicated that 4 months of treatment with LAC exerted a neuroprotective effect. LAC reduced pain in patients with mild and moderate CTS, a result that is possibly due to both its neuroprotective action and its central anti-nociceptive properties.

Little is known about treatment effect of carpal tunnel release in patients with clinically defined carpal tunnel syndrome (CTS), but normal electrodiagnostic test results (EDX). The aim of this study was to determine whether this category of patients will benefit from surgical treatment. 57 patients with clinically defined CTS and normal EDX were randomized for surgical treatment ( n = 39) or non-surgical treatment ( n = 18). A six-point scale for perceived improvement as well as the Boston Carpal Tunnel Questionnaire was completed at baseline and at follow-up after 6 months. A significant improvement of complaints was reported by 70.0% of the surgically treated patients and 39.4% reported full recovery 6 months after surgery. Furthermore, both Functional Status Score and Symptom Severity Score improved significantly more in the surgically treated group ( p = 0.036 and p < 0.001, respectively). This study demonstrates that most patients with clinically defined CTS and normal EDX results will benefit from carpal tunnel release. Therefore, this group of CTS patients must not a priori be refrained from surgery. [ABSTRACT FROM AUTHOR]

Background/aim: This study aimed to compare the effectiveness of ultrasound (US)-guided injection versus blind injection of corticosteroids in the treatment of carpal tunnel syndrome (CTS). Materials and methods: This prospective, randomized clinical trial included patients with severe CTS based on clinical and electrophysiological criteria. The patients were evaluated for clinical and electrophysiological parameters at baseline and 4 weeks after treatment. Symptom severity and hand function were assessed by the Boston questionnaire. The patients underwent blind injection or US-guided injection. Results: When compared with baseline, both groups showed significant improvement in Boston questionnaire scores and all electrophysiological parameters. Significant differences were observed between the groups for clinical parameters (Boston Symptom Severity Scale: P = 0.007; Functional Status Scale: P < 0.001) in favor of the US-guided group. Conclusion: This study demonstrated that both US-guided and blind injections were effective in reducing symptoms and improving hand function. US-guided injections may yield more effective clinical results in the short-term than blind injections in the treatment of patients with severe CTS. [ABSTRACT FROM AUTHOR]

Carpal tunnel syndrome (CTS) is the most frequently diagnosed neuropathy of upper extremity entrapment neuropathies. We aimed to investigate the effectiveness of paraffin therapy in patients with CTS. Seventy patients diagnosed with mild or moderate CTS were randomly divided into two groups as splint treatment (during the night and day time as much as possible for 3 weeks) alone and splint (during the night and day time as much as possible for 3 weeks) + paraffin treatment (five consecutive days a week for 3 weeks). Clinical and electrophysiological assessments were performed before and 3 weeks after treatment. The patients were assessed by using visual analog scale (VAS) for pain, electroneuromyography (ENMG), and Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ). The significant improvement was found in VAS scores in both groups when compared with pretreatment values ( p < 0.05). There was no significant improvement in functional capacity score ( p > 0.05), whereas a significant improvement was noted in the BCTQ symptom severity scale score in the splint group ( p < 0.05). Significant improvements were demonstrated in both scorers in the combined treatment group. Similarly, significant improvements were found in the combined treatment group in terms of motor and sensory distal latency, sensory amplitude, and median sensory nerve velocity ( p < 0.05). There was no significant change in electrophysiologic parameters in the splint group ( p > 0.05), and the difference in these parameters between the groups was statistically significant ( p < 0.05). In conclusion, using splinting alone in patients with CTS is an effective treatment for reducing symptoms in the early stages. Paraffin treatment with splint increases the recovery in functional and electrophysiological parameters. [ABSTRACT FROM AUTHOR]

The median nerve is the most important nerve in the upper extremity, as it is responsible for most of the sensation of the hand, the fine motor functions of the thumb, and finger grasping. Median neuropathies most commonly occur as compressive neuropathy or entrapment neuropathy, but sometimes as neuritis without any compressive lesion. Carpal tunnel syndrome (CTS), anterior interosseous nerve syndrome, and pronator teres syndrome are the subtypes of median nerve neuropathies, of which CTS is the most common. Median neuropathies can be diagnosed clinically by careful history-taking and a physical examination. Typical symptoms of CTS include night pain (crying), a tingling sensation of the radial digits, numbness or paresthesia, clumsiness, and atrophy of the thenar muscles. Electrophysiologic testing can be used for confirmation of the diagnosis and for documentation before surgical treatment. Imaging modalities including ultrasonography or magnetic resonance imaging can be used to ensure diagnostic accuracy and to detect unusual causes of compression. Conservative treatments include rest, bracing, nerve stretching, non-steroidal anti-inflammatory drugs, and steroid injections. If nonsurgical approaches are unsatisfactory or the nerve damage is severe, surgical treatment should be considered. Carpal tunnel release for CTS is a relatively simple procedure that involves division of the transverse carpal ligament and decompression of the median nerve. Early diagnosis and proper management are important, as muscle atrophy and sensory loss may persist when surgical release is delayed in patients with advanced disease. [ABSTRACT FROM AUTHOR]

Entrapment neuropathy is the result of pressure on a peripheral nerve as it passes through a narrow canal that is bounded by stiff tissues. In spite of their ubiquitous nature, they are underdiagnosed, underreported, and sometimes not properly managed, especially in developing countries. Entrapment neuropathies are of various types, but the most common type is carpal tunnel syndrome. Mechanisms involved in the pathophysiology of entrapment neuropathies include mechanical compression and nerve ischemia. A clear understanding of the various types and the underlying mechanisms of entrapment neuropathies are invaluable in the decision-making process involved in the management of every patient with the condition.

Background: Carpal tunnel syndrome (CTS) is a common, compressive nerve-entrapment disorder with symptoms of numbness, paresthesia, and pain. Carpal tunnel release surgery is the only known long-term effective treatment. However, surgery is invasive and up to 30% of patients report recurrence or persistence of symptoms or suffer from post-surgical complications. A promising non-surgical treatment for CTS is mechanical wrist traction. The purpose of this study was to evaluate clinical outcomes following mechanical traction in patients with CTS compared to care as usual.Methods: Adult patients (N = 181, mean age 58.1 (13.0) years, 67% women) with electrodiagnostically confirmed CTS were recruited from an outpatient neurology clinic in the Netherlands between October 2013 and April 2015. After baseline assessments, patients were randomized to either the intervention group (12 treatments with mechanical traction, twice a week for a period of 6 weeks) or "care as usual". The main clinical outcome measure was surgery during 6 months' follow-up. In addition, symptom severity was measured using the Boston Carpal Tunnel Questionnaire (BCTQ) at baseline, 3, and 6 months' follow-up. Baseline characteristics and severity of CTS symptoms at follow-up were compared between the intervention and care-as-usual groups using a t test and χ 2 tests. Time to event (surgery) between the groups was analyzed using Kaplan-Meier survival analysis and Cox proportional hazards analysis.Results: The intervention group had fewer surgeries (28%) compared to the care-as-usual group (43%) during follow-up (χ21 = 4.40, p = .036). Analyses of the survival curves revealed a statistically significant difference between the groups over time (log-rank test χ 21 = 6.94, p = .008). At 6 months' follow-up, symptom severity and functional status scores had significantly decreased from baseline in both groups (p < .001) and the improvements did not differ between the two groups.Conclusions: Mechanical traction is associated with fewer surgical interventions compared to care as usual in CTS patients. Reductions in patient-reported symptoms at 6 months' follow-up was similar in both groups. The long-term effects of mechanical traction require further evaluation.Trial Registration: ClinicalTrials.gov, ID: NL44692.008.13 . Registered on 19 September 2013. [ABSTRACT FROM AUTHOR]

Objective: Carpal Tunnel Syndrome is a common entrapment syndrome which lowers quality of life and is a reason for high costs for health care systems. The algorithm presented in this study may be helpful for surgeons' decision-making for treatment of Carpal Tunnel Syndrome in terms of correct timing and treatment option. Here, the treatment algorithm for carpal tunnel syndrome and its preliminary results are discussed. Material and Methods: Decision-making for treatment of all Carpal Tunnel Syndrome patients enrolled in this study was performed according to the algorithm presented here, which is based on no thenar atrophy of patients and ability of median nerve innervated thenar muscles. Fifty one hands out of 88 were offered night splinting initially for three weeks while the rest thirty seven hands were operated as an emergent or urgent case without offering night splinting. Results: Quality of life of all the patients who were operated was improved except one and, awakening at night was disappeared in the postoperative period. 20 hands out of fifty one who were offered night splinting for three weeks were operated for carpal tunnel release since patients felt no improvement in their complaints after three weeks of night splinting. Conclusion: We believe that, this algorithm will help surgeons in decision-making process, determining the correct timing for surgery, improve patient satisfaction and provide the opportunity for explanation of the need for whichever treatment option is required. The algorithmic approach we use in our cases is based on the examination of no thenar atrophy and ability of median nerve innervated thenar muscles. [ABSTRACT FROM AUTHOR]

Objectives A number of studies have demonstrated the neuroprotective effects of progesterone and its influence on the recovery after neural injury. Few studies investigated the efficacy of local progesterone in carpal tunnel syndrome. The objective of this study was to compare the long-term effects of progesterone vs corticosteroid local injections in patients with mild and moderate carpal tunnel syndrome. Methods In this randomized clinical trial, 78 patients with carpal tunnel syndrome were assigned to two groups. Patients were treated with a single local injection of triamcinolone acetonide in one group and single local injection of hydroxy progesterone in the other group. Variables including pain (based on visual analogue scale), symptom severity, and functional status (based on Bostone/Levine symptom severity and functional status scale) and nerve conduction study were evaluated before and 6 months after the treatments. Results All outcome measures including pain and electrophysiologic findings, improved in both groups and there were no meaningful differences between two groups regarding mentioned variables except for functional outcome, which was significantly better in progesterone compared with corticosteroid group at 6-month follow-up ( P=.04). Conclusions The efficacy of progesterone local injection in mild and moderate CTS is equal and somehow superior to corticosteroid injection for relieving symptoms and improving functional and electrophysiologic findings at long-term follow-up.

Background: Carpal tunnel syndrome is a common peripheral nerve compressive neuropathic disorder and severe symptoms are managed by surgical decompression. However, long-term outcome data is limited. Objectives: To study the long-term outcome of surgical decompression in severe carpal tunnel syndrome in terms of improvement in nocturnal pain and numbness. Methods: This is a prospective quasi-experimental study of 18-month duration conducted at Bacha Khan Medical Complex, Swabi. 30 patients who were operated for severe carpal tunnel syndrome were included in the study and were followed for an average of 18 months (range: 6 - 24 months). Data was collected about preoperative and postoperative pain scores in terms of visual analogue scale (VAS). A patient satisfaction survey using a five-item Likert scale was conducted at the end of 6-months. Outcome was categorised according to pain scores and satisfaction. Results: All werefemale patients with mean age of 42.5 ± 8.1 years. The mean preoperative VAS was 6.9 ± 0.9 and mean postoperative VAS was 2.1 ± 1.4. The median satisfaction score was 4 (satisfied) with a range: 1 - 5. Overall 23 (76.7%) patients had favourable outcome while 7 (23.3%) patients had unfavourable outcome. Patients who had symptoms for longer than 12 months were more likely to have an unfavourable outcome as compared to those who had less 12 months of symptoms (p < 0.0001). Conclusion: Severe carpal tunnel syndrome responds quickly to the open release technique and patient satisfaction is higher. However, longer symptoms duration is a factor which can result in unfavourable outcome in terms of pain relief and relief from numbness. [ABSTRACT FROM AUTHOR]

Study Design Systematic review. Introduction Median nerve mobilization is one of the interventions used in the treatment of carpal tunnel syndrome (CTS). However, it is uncertain how many types of mobilization techniques are described in the current literature or the relative effectiveness of these techniques in treating CTS. Purpose of the Study The aim of this review was to describe the types and effectiveness of median nerve mobilization techniques studied in the CTS literature. Methods Electronic searches of 5 databases and manual searches of references lists located randomized controlled trials studies published between 2000 and April 2015. Quality appraisal for each study was conducted using the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields by 2 independent reviewers. Results Nine randomized controlled trial studies describing various median nerve mobilization techniques used in the treatment of CTS were included. All studies were rated as of “adequate”, “good”, or “strong” quality for the Standard Quality Assessment Criteria. Three techniques of median nerve mobilization were described. Treatment outcomes included measures of electrodiagnostic testing, functional performance, pain, physical examination, sensation, and strength. Standardized mean differences for the treatment outcomes ranged from very small to large (0.05-1.71). Conclusion The findings are inconclusive regarding the effectiveness of each mobilization technique due to methodological limitations in the current body of research. Therefore, there is a clear need for high-quality controlled studies to examine various approaches to median nerve mobilization techniques in the treatment of CTS. Level of Evidence 2a.

A 38-year-old man with pancreatic cancer was scheduled to undergo pancreaticoduodenectomy. He had an unremarkable past medical history. After inducing general anesthesia, a left radial arterial catheter was successfully placed at first attempt. A wrist splint was used to obtain good arterial pulse waveforms. After the operation, he was transferred to the intensive care unit. The radial artery catheter was removed on the fourth postoperative day. He experienced numbness and a tingling sensation in the left thumb, the second and third fingers, and the lateral half of the fourth finger. He was diagnosed with carpal tunnel syndrome. Diagnostic imaging revealed a swollen median nerve, but no hematoma or injury. Some studies have suggested that excessive extension of the wrist may cause neuropathy. We recommend that patients' wrists not be over-extended, even if good arterial waveforms cannot be obtained. [ABSTRACT FROM AUTHOR]

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy accounting for 90% of similar disorders, occurring in 3.8% of the population, common in adults aged 40-60 years, and is associated with an average 32 lost days of work and lost productivity. In addition to occupational exposure, there are several common chronic disorders that can preclude CTS, obesity, diabetes mellitus, rheumatoid arthritis, pregnancy, metabolic syndrome, and thyroid disorder, to name a few. Therefore, it is important for the primary care provider to have knowledge in this syndrome. The purpose of the article is to inform the provider about the etiology, presentation, diagnosis, and treatment of CTS, as well as the implications for job-associated CTS. [ABSTRACT FROM AUTHOR]

We performed this meta-analysis to investigate the efficacy of low-level laser therapy (LLLT), a physiotherapy modality with anti-inflammatory and analgesic effects, in the management of mild-to-moderate carpal tunnel syndrome (CTS). We searched PubMed, Web of Knowledge, Scopus, Cochrane Central, and Virtual Health Library for randomized controlled trials (RCTs) that compared the effects of LLLT with or without splinting versus placebo on functional and electromyographic outcomes in CTS. All outcomes were pooled as mean differences (MD) under the inverse variance or random effects model, using the statistical add-in (MetaXL, version 5.0). Eight RCTs (473 patients/631 wrists) were eligible for the final analysis. The overall effect estimates did not favor LLLT therapy group over placebo in all primary outcomes: visual analogue scale (MD -1.11, 95% CI [-2.58, 0.35]), symptom severity scale score (MD -1.41, 95% CI [-5.12, 2.29]), and functional status scale score (MD -1.33, 95% CI [-3.27, 0.61]). However, LLLT was superior to placebo in terms of grip strength (MD 2.19, 95% CI [1.63, 2.76]) and inferior to placebo in terms of sensory nerve action potential (MD -2.74, 95% CI [-3.66, -1.82]). Laser therapy is superior to placebo in terms of improving the grip strength; however, no significant difference was found between both groups in terms of functional status improvement, pain reduction, or motor electrodiagnostic evaluations. Further high-quality trials with longer follow-up periods are required to establish the efficacy of LLLT for CTS treatment. [ABSTRACT FROM AUTHOR]

Background: To compare the clinical effectiveness of ultrasound-guided corticosteroid injection with and without needle release of the transverse carpal ligament (TCL) in carpal tunnel syndrome (CTS). Methods: Between May 2014 and June 2016, 52 patients (56 wrists) with CTS were included in this study. Among these patients, 28 wrists were treated with ultrasound-guided corticosteroid injection plus needle release of the TCL (group A) and 28 wrists were treated with a single ultrasound-guided corticosteroids injection (group B). The following parameters were assessed and compared including postoperative results of procedure based on relief of symptoms, electrophysiological parameters (distal motor latency, sensory conduction velocity, and sensory nerve action potential of median nerve), and ultrasound parameters (anteroposterior diameter and cross-sectional area of the median nerve at the levels of pisiform and hamate bone, and the thicknesses of TCL on the cross-section at the level of hamate bone). Results: The overall excellent and good rate regarding the postoperative results of procedure based on the relief of symptoms at 1 month postoperatively was 82.1% in group A and 46.4% in group B (p = 0.004). There was significant difference in the above electrophysiological and ultrasound parameters between the preoperative and postoperative values in both groups (all p < 0.05). Furthermore, a significant difference was also observed in the postoperative values of the above-mentioned electrophysiological and ultrasound parameters in the 2 groups (all p < 0.05). Conclusions: Both approaches had treatment benefit in CTS. Ultrasound-guided corticosteroid injection in combination with needle release of the TCL is superior to the single ultrasound-guided corticosteroids injection. [ABSTRACT FROM AUTHOR]

Background: Therapeutic ultrasound is an often-used clinical modality in the nonsurgical treatment of entrapment neuropathies. To date, the possible mechanism of action of pulsed ultrasound therapy on the peripheral nerve in the treatment of entrapment neuropathies is unclear.Objective: To examine the effects of pulsed ultrasound therapy on peripheral nerve conduction parameters.Design: A prospective, randomized, single blind, crossover study.Setting: Outpatient clinic of a university department of physical medicine and rehabilitation.Participants: Twelve healthy volunteers between 22 and 38 years of age (8 male, 4 female).Methods: Each patient (blinded) received ultrasound therapy (1W/cm2, pulsed: 1:5; over the course of the superficial branch of the radial nerve of the nondominant arm) and placebo (intensity: zero). The interval between the individual interventions was 1 week.Main Outcome Measurement: The sensory nerve conduction velocity, sensory nerve action potential, supramaximal stimulation intensity of the sensory fibers of the radial nerve, and the pressure pain threshold in the sensory area of the radial nerve before and after an ultrasound-therapy and placebo intervention. To compare the results of the intervention with placebo, a paired-samples t test was applied.Results: Compared with placebo, a significant increase after pulsed ultrasound therapy was found for the supramaximal stimulation intensity (P = .02). For the other primary outcome parameters, a significant difference was not found.Conclusions: The immediate effect of pulsed ultrasound therapy on a sensory nerve is minimal. Therefore, the previously reported benefit of pulsed ultrasound therapy in entrapment neuropathies might be not due to its effect on the sensory nerve.Level Of Evidence: I. [ABSTRACT FROM AUTHOR]

Objective: To determine the natural history of the morphology of the median nerve after carpal tunnel decompression. Methods: Between October and December 2014, patients with suspected carpal tunnel were prospectively enrolled and underwent pre- and postoperative (3 and 6 months) high-definition ultrasonography, electrophysiology, and clinical testing. Results: A total of 81 patients were enrolled in the study; 75 (93%) could be reached for the 6-month follow-up, and 100% were clinically better at the 6-month follow-up. The mean cross-sectional area decreased from 14.3 ± 4.4 mm2 to 9.6 ± 2.3 mm2 (mean ± standard deviation [SD]). The mean distal motor latency decreased from 6.5 ± 2.2 msec to 4.4 ± 0.8 msec (mean ± SD). Distal motor latency improved statistically significantly after surgical decompression as well, but sooner. Conclusion: We present the second largest series of patients with sonographic followup after surgical decompression of the carpal tunnel. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate in a prospective study the possibility of visualization and diagnostic assessment of the recurrent motor branch (RMB) of the median nerve with high-resolution ultrasound (HRUS).Materials and Methods: HRUS with high-frequency probes (18-22 MhZ) was used to locate the RMB in eight fresh cadaveric hands. To verify correct identification, ink-marking and consecutive dissection were performed. Measurement of the RMB maximum transverse-diameter, an evaluation of the origin from the median nerve and its course in relation to the transverse carpal ligament, was performed in both hands of ten healthy volunteers (n = 20). Cases referred for HRUS examinations for suspected RMB lesions were also assessed.Results: The RMB was clearly visible in all anatomical specimens and all volunteers. Dissection confirmed HRUS findings in all anatomical specimens. Mean RMB diameter in volunteers was 0.7 mm ± 0.1 (range, 0.6-1). The RMB originated from the radial aspect in 11 (55%), central aspect in eight (40%) and ulnar aspect in one (5%) hand. Nineteen (95%) extraligamentous courses and one (5%) subligamentous course were detected. Three patients with visible RMB abnormalities on HRUS were identified.Conclusion: HRUS is able to reliably visualize the RMB, its variations and pathologies.Key Points: • Ultrasound allows visualization of the recurrent motor branch of the median nerve. • Ultrasound may help clinicians to assess patients with recurrent motor branch pathologies. • Patient management may become more appropriate and targeted therapy could be improved.

Background: Carpal tunnel syndrome (CTS) is the most commonly known entrapment neuropathy in which median nerve of the body is compressed or traumatized. The problem is described by numbness and tingling sensation in the region of tangible dispersion of the nerve in the hand that is joined by torment as well as shortcoming of thumb muscles. The incidence rate of CTS is 139/100,000 per year for men and 506/100,000 per year for women. Objective: To compare the difference in pre/post numeric pain rating scale scores (NPRS) and Boston carpal tunnel syndrome questionnaire scores (BCTSQ) with the use of therapeutic ultrasound versus local steroid injection in the treatment of mild to moderate carpal tunnel syndrome. Methodology: A Randomized clinical trial was done at Mayo Hospital Lahore, after the approval of synopsis from March 2016 to August 2016.The Sample size of 60 patients (30 subjects in every group) was assessed by utilizing 5% level of significance, 90% power of test with expected mean estimation of BCTSQ score of local steroid as 3.20 and therapeutic ultrasound as 2.39 using simple random technique. Patients were given treatment with therapeutic ultrasound along with tendon gliding exercises in one group and local steroid injection along with tendon gliding exercises in another group. Post treatment assessment was done after four weeks. Results: Pre-treatment pain intensity mean±SD for group 1 was 2.900±0.80 and for group 2 were 2.77±0.82 that was changed to 1.67±1.18 and 21.63±1.07 after four week treatment respectively. The functional status score mean±SD before treatment was 2.51±0.30 on symptom severity scale, 2.42±0.32 on functional status scale for group 1and 2.32±0.34 (SSS), 2.17±0.45 (FSS) for group 2 that were changed after four week treatment to 1.94±0.44 (SSS), 1.89±0.51 (FSS) and1.97±0.27 (SSS), 1.78±0.42 (FSS) for group 2 respectively. Conclusion: The patients who were treated with therapeutic ultrasound method (U/S Group) showed better recovery after treatment, in case of symptoms severity scale. In case of function status scales the patients who were treated with local steroid method (Injectable Group) recovered better after treatment. [ABSTRACT FROM AUTHOR]

This study compared the therapeutic effect of flax seed oil topical gel and hand splint in the treatment of carpal tunnel syndrome. This study was a randomized clinical trial. Forty-nine patients, 96 hands, with mild to moderate idiopathic carpal tunnel syndrome were divided into 2 groups randomly. One group was treated by topical gel and the other group by hand splint. Intensity of symptoms and function before and after intervention was measured via Boston Carpal Tunnel Questionnaire. After intervention, the ANCOVA showed a significant difference between the symptom and function scores of the 2 groups. In both cases, recovery was higher in the gel group (P < .001). The topical use of flax seed oil gel is more effective in the improvement of symptoms and function of patients with mild to moderate carpal tunnel syndrome as compared with hand splint, and it can be introduced as an effective treatment.

Introduction. The aim of this study was to explore the acupuncture effect on the cross-sectional area (CSA) of the median nerve at the wrist in patients with carpal tunnel syndrome (CTS) and, additionally, to identify whether clinical, electrophysiological, and ultrasonographic changes show any association. Methods. Forty-five limbs of 27 female patients were randomly divided into two groups (acupuncture and control). All patients used night wrist splint. The patients in the acupuncture group received additional acupuncture therapy. Visual analog scale (VAS), Duruöz Hand Index (DHI), Quick Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire scores, electrophysiologic measurements, and median nerve CSAs were noted before and after the treatment in both groups. Results. VAS, DHI, Quick DASH scores, and electrophysiological measurements were improved in both groups. The median nerve CSA significantly decreased in the acupuncture group, whereas there was no change in the control group. Conclusion. After acupuncture therapy, the patients with CTS might have both clinical and morphological improvement. [ABSTRACT FROM AUTHOR]

Background: Although surgery is an effective treatment for severe carpal tunnel syndrome (CTS), it is accompanied by many complications; furthermore, there are several patients with severe CTS who reject surgical management. This study was designed to investigate the efficacy of long-term splinting in severe CTS. Methods and Materials: CTS Assessment Questionnaire (Bostone) was filled for 140 patients with severe CTS, who did not agree to go under surgery. Patients were divided into two groups randomly. One group received medical and physical therapy and short-term (six weeks) wrist splint. The other group received the same treatments but long-term (six months) splinting. Both groups went under the evaluation of symptoms and function with Bostone questionnaire and electrophysiological study six weeks, and six months later. Results: There was no significant difference between two groups in any of the measured or registered parameters at the beginning of the study and six weeks later except for compound motor action potential amplitude. But, both the Boston questionnaire scores (symptom severity and functional capacity) and nerve conduction study results were significantly different between the two groups at six months. Conclusion: Regarding the potential efficacy of long-term night-time splinting for symptom and functional improvement of severe CTS, we recommend its use in severe CTS patients who reject surgery.

Purpose: A minimally invasive surgical technique has been introduced to treat carpal tunnel syndrome that causes less pain, minimal scaring, and a rapid recovery. This study was designed to evaluate the safety and effectiveness of the double minimal incision release compared with the open surgery technique. Methods: A study was performed on 175 cases in 111 patients who were operated on for carpal tunnel syndrome from January 2010 to December 2014. The patients were classified into 2 groups according to the type of surgical technique: 82 cases underwent standard open surgery in group A and 93 cases underwent double minimal incision release in group B. Grip strength and postoperative pain were evaluated 4 and 8 weeks and 6 and 12 months after surgery, and the period of numbness and time needed to resume normal activities were investigated. Results: Group B patients showed better outcomes during the 2 first months after surgery than those of group A patients in numbness, pain, stiffness (p<0.05), less scar pain and tenderness (p<0.001), and shorter time needed to resume normal activities. However, no differences in these parameters were observed between the 2 groups after 6 months (p>0.05). Conclusion: Double minimal incision release offered better clinical outcomes until 2 months after surgery compared to the standard open surgery technique and reduced incipient postoperative pain and allowed for earlier resumption of normal activities.

Objective: Mini skin incision technique for median nerve release have become popular recently for the treatment of carpal tunnel syndrome. The main advantages of this technique are shorter recovery time and better cosmetic results. Neurovascular injury still remains controversial. We presented the advantages, disadvantages and results of transverse mini skin incision technique to release carpal tunnel syndrome. Method: 62 carpal tunnel releasing procedures were performed.52 female and 10 male patients with mean age of 62 (ranging from 38 to 82) included in this study. All patients were operated by using transverse mini skin incision technique. Results: Significant improvement was observed in symptoms and signs during the postoperative follow-up period. No recurrence or injury to the neurovascular structures was noted. Conclusions: The technique is simple and effective. Without using expensive instruments better cosmetic results and better recovery time can be achieved. [ABSTRACT FROM AUTHOR]

Clinical assessment of the hand is important for diagnosing underlying hand disorders. Using a case study approach, the clinical assessment for three disorders of the hands is presented: trigger finger (stenosing tenosynovitis), carpal tunnel syndrome, and ulnar-sided wrist injury (styloid impingement). We assess the annular one pulley and finger range of motion for patients with trigger finger. To diagnose for carpal tunnel syndrome, assessment for Tinel's sign, Phalen's sign, abductor pollicis brevis muscle bulk, two-point discrimination, and obtaining a nerve conduction study are performed. Assessment for ulnar-sided wrist injury includes wrist range of motion, assessment of distal radial ulnar joint stability, provocation tests, grip strength, x-ray, and magnetic resonance imaging. This article begins with a description of the hand and wrist anatomy. For each case study, the clinical history is described, followed by a discussion of the pathophysiology, clinical assessments, and diagnostic tests. [ABSTRACT FROM AUTHOR]

Objective The purpose of this randomized trial was to compare the efficacy of manual therapy, including the use of neurodynamic techniques, with electrophysical modalities on patients with mild and moderate carpal tunnel syndrome (CTS). Methods The study included 140 CTS patients who were randomly assigned to the manual therapy (MT) group, which included the use of neurodynamic techniques, functional massage, and carpal bone mobilizations techniques, or to the electrophysical modalities (EM) group, which included laser and ultrasound therapy. Nerve conduction, pain severity, symptom severity, and functional status measured by the Boston Carpal Tunnel Questionnaire were assessed before and after treatment. Therapy was conducted twice weekly and both groups received 20 therapy sessions. Results A baseline assessment revealed group differences in sensory conduction of the median nerve ( P < .01) but not in motor conduction ( P = .82). Four weeks after the last treatment procedure, nerve conduction was examined again. In the MT group, median nerve sensory conduction velocity increased by 34% and motor conduction velocity by 6% (in both cases, P < .01). There was no change in median nerve sensory and motor conduction velocities in the EM. Distal motor latency was decreased ( P < .01) in both groups. A baseline assessment revealed no group differences in pain severity, symptom severity, or functional status. Immediately after therapy, analysis of variance revealed group differences in pain severity ( P < .01), with a reduction in pain in both groups (MT: 290%, P < .01; EM: 47%, P < .01). There were group differences in symptom severity ( P < .01) and function ( P < .01) on the Boston Carpal Tunnel Questionnaire. Both groups had an improvement in functional status (MT: 47%, P < .01; EM: 9%, P < .01) and a reduction in subjective CTS symptoms (MT: 67%, P < .01; EM: 15%, P < .01). Conclusion Both therapies had a positive effect on nerve conduction, pain reduction, functional status, and subjective symptoms in individuals with CTS. However, the results regarding pain reduction, subjective symptoms, and functional status were better in the MT group. [ABSTRACT FROM AUTHOR]

The carpal tunnel syndrome is one of the most common entrapment neuropathies found in humans. Currently, the gold standard is surgical treatment using different modalities. The minimally invasive strategy with high resolution capacity and less morbidity is still a challenge. Methods. Prospective nonrandomised clinical trial in which a minimally invasive microsurgical approach was used following the keyhole principle in 55 consecutive patients and 65 hands under local anesthesia and ambulatory strategy. They were evaluated with stringent inclusion criteria with the Levine severity and functional status scale and with a 2-year follow-up. Results. 90% showed immediate improvement dropping to grades 1-2 in all items of the scale referring to pain and numbness. 97% reported improvement, as of the first month, and 3% reported persistence of symptoms, although at a lesser degree and with no functional limitation. No incidents were identified during the procedure and 98% of patients were discharged within an hour after the surgical procedure. Conclusions. The microsurgical approach described following the keyhole principle is a treatment option that, under local anesthesia and ambulatory management, may represent an alternative strategy of an effective treatment reducing the morbidity. This trial is registered with Clinical Trials Protocol Identifier NCT03062722. [ABSTRACT FROM AUTHOR]

Carpal tunnel syndrome is the most common entrapment neuropathy, affecting the median nerve at the wrist. Acupuncture is a minimally-invasive and conservative therapeutic option, and while rooted in a complex practice ritual, acupuncture overlaps significantly with many conventional peripherally-focused neuromodulatory therapies. However, the neurophysiological mechanisms by which acupuncture impacts accepted subjective/psychological and objective/physiological outcomes are not well understood. Eligible patients (n = 80, 65 female, age: 49.3 ± 8.6 years) were enrolled and randomized into three intervention arms: (i) verum electro-acupuncture 'local' to the more affected hand; (ii) verum electro-acupuncture at 'distal' body sites, near the ankle contralesional to the more affected hand; and (iii) local sham electro-acupuncture using non-penetrating placebo needles. Acupuncture therapy was provided for 16 sessions over 8 weeks. Boston Carpal Tunnel Syndrome Questionnaire assessed pain and paraesthesia symptoms at baseline, following therapy and at 3-month follow-up. Nerve conduction studies assessing median nerve sensory latency and brain imaging data were acquired at baseline and following therapy. Functional magnetic resonance imaging assessed somatotopy in the primary somatosensory cortex using vibrotactile stimulation over three digits (2, 3 and 5). While all three acupuncture interventions reduced symptom severity, verum (local and distal) acupuncture was superior to sham in producing improvements in neurophysiological outcomes, both local to the wrist (i.e. median sensory nerve conduction latency) and in the brain (i.e. digit 2/3 cortical separation distance). Moreover, greater improvement in second/third interdigit cortical separation distance following verum acupuncture predicted sustained improvements in symptom severity at 3-month follow-up. We further explored potential differential mechanisms of local versus distal acupuncture using diffusion tensor imaging of white matter microstructure adjacent to the primary somatosensory cortex. Compared to healthy adults (n = 34, 28 female, 49.7 ± 9.9 years old), patients with carpal tunnel syndrome demonstrated increased fractional anisotropy in several regions and, for these regions we found that improvement in median nerve latency was associated with reduction of fractional anisotropy near (i) contralesional hand area following verum, but not sham, acupuncture; (ii) ipsilesional hand area following local, but not distal or sham, acupuncture; and (iii) ipsilesional leg area following distal, but not local or sham, acupuncture. As these primary somatosensory cortex subregions are distinctly targeted by local versus distal acupuncture electrostimulation, acupuncture at local versus distal sites may improve median nerve function at the wrist by somatotopically distinct neuroplasticity in the primary somatosensory cortex following therapy. Our study further suggests that improvements in primary somatosensory cortex somatotopy can predict long-term clinical outcomes for carpal tunnel syndrome. [ABSTRACT FROM AUTHOR]

Background: Although a model for shared decision-making is important for patient-centered care, decisional conflict can emerge when patients participate in the decision-making. A decision aid is proposed to provide information and to involve patients more comfortably in the decision-making process. We aimed to determine whether a decision aid helps patients with carpal tunnel syndrome (CTS) experience less decisional conflict regarding their decision-making for surgery.Methods: Eighty patients with CTS were randomized into two groups. The test group was given a decision aid in addition to regular information and the control group regular information only. The decision aid consisted of a 6-min videoclip that explains diagnosis and information regarding surgery for CTS with other treatment options. We evaluated patients' decisional conflict regarding surgery, knowledge about CTS, and symptom severity as measured by the Disabilities of Arm, Shoulder, and Hand (DASH) Questionnaire.Results: There was no difference in the decisional conflict scale (DCS) between both groups (p = 0.76). The test group had significantly better knowledge than the control group (p = 0.04). There was no correlation between the knowledge score and the DCS (p = 0.76). However, less severe symptoms were correlated with greater decisional conflict (r = -0.29, p = 0.02).Conclusions: We found that a decision aid does not reduce decisional conflict in patients with CTS, although it can help them be better informed. This study suggests that although a decision-aid is effective for patient education, doctor-patient communication should be more emphasized for patients with less severe symptoms, as they can have greater decisional conflict.Trial Registration: SNUBH Registry 1510/317-003 Registered November 13, 2015.
