To translate, cross-culturally adapt, and psychometric testing the Western Ontario Shoulder Instability index (WOSI) into Persian Seventy-two patients diagnosed with shoulder instability participated in reliability, construct validity, and responsiveness analysis. All the patients filled out the WOSI with an interval of two weeks to assess reliability. The shortened Disability of Arm, Shoulder and Hand (Quick-DASH), Shoulder Pain and Disability Index (SPADI), and the 36-Item Short-Form Survey (SF-36) were assessed to evaluate construct validity. In order to assess responsiveness patients filled out WOSI before and after the physiotherapy and global rating of change scale at last session of physiotherapy. Reliability was assessed by intra-class correlation coefficient (ICC (1,2)), construct validity by two tailed Pearson (r), and responsiveness by longitudinal validity and receiver operating characteristics (ROC) curve analysis. The ICC (1,2) was 0.90 and correlation analysis revealed high level of correlation with: Quick-DASH (r = 0.82); SPADI (r = 0.72); physical SF-36 (r = −0.52); and mental SF-36 (r = −0.48). Responsiveness analysis demonstrated the area under curve was 0.90, with minimal clinical important difference 46.87. We found the Persian-WOSI as a valid, reliable, and responsive questionnaire to evaluate quality of life of patients with shoulder instability. [ABSTRACT FROM AUTHOR]

The Osteoarthritis Research Society International has recommended a core set of performance-based tests of physical function for use in knee osteoarthritis (OA) patients. The core set includes 30-second chair stand test (30-s CST), 4 × 10 m fast-paced walk test (40-m FPWT), and a stair climb test. This study aimed to evaluate responsiveness and minimal important changes (MICs) of these performance-based measures in knee OA patients following physiotherapy. Sixty patients with knee OA, undergoing 4-week physiotherapy performed 30-s CST, 40-m FPWT, and 4-step stair climb test (4-step SCT) at pre- and post-intervention. Patients also completed the 7-point global rating scale as an external anchor at post-intervention. Responsiveness was evaluated using receiver operating characteristics curve and correlation analysis. All three performance-based measures of physical function showed area under the curve > 0.70. Correlation analysis showed relationship of 30-s CST, 40-m FPWT, and 4-Step SCT with the external anchor fell within moderate to good range (Spearman = 0.43–0.63). Furthermore, MIC values reflecting improvement for 30-s CST, 40-m FPWT, and 4-Step SCT were 2.5, 0.21, and 3.21, respectively. Our findings demonstrated all three performance-based measures have good responsiveness to measure improvement in physical functions of knee OA patients following physiotherapy. The MIC reflecting improvement can help clinicians and researchers to make a decision based on the clinical significance of improvements in patients' functional status. [ABSTRACT FROM AUTHOR]

The aims of this study were to evaluate the diagnostic accuracy of common physical examination and functional evaluation tests, and to determine a set of tests with the highest diagnostic accuracy for diagnosing patellofemoral pain syndrome (PFPS) in patients with anterior knee pain. Based on careful evaluation of clinical findings and imaging methods by orthopedic physicians, 162 patients with anterior knee pain were classified into two groups of PFPS and non-PFPS. The physical examination and functional tests were performed by two physiotherapists. The accuracy of these measures was determined by calculating sensitivity, specificity, area under the receiver operating characteristic (ROC) curve (AUC), likelihood ratio (LR), and predictive value (PV). Our results showed the most sensitive tests in identifying patients with PFPS were as follows: eccentric step test [0.82 (95%CI: 0.72–0.89)]; palpation test [0.81(95%CI: 0.70–0.88)]; and prolonged sitting [0.73 (95%CI: 0.62–0.82)]. The palpation test, patellar tilt test, eccentric step test, navicular drop test, squatting, and stair descending tests had an acceptable accuracy (AUC ≥ 70). The strongest combination of the physical examination and functional tests included pain severity between 3 and 10 during stair descending test and pain severity between 6 and 10 during prolonged sitting test. This combination showed a positive LR of 19.47 (95% CI: 6.36–59.65) and a posttest probability of 95%. Our findings provide evidence for the good accuracy of the palpation test, patellar tilt test, eccentric step test, navicular drop test, squatting, and stair descending and prolonged sitting tests for diagnosing PFPS. Also, the combination of stair descending test and prolonged sitting test could be very useful for ruling in PFPS patients. [ABSTRACT FROM AUTHOR]

Purpose: To compare the short and medium-term effects of physiotherapy plus corticosteroid injection (combined) with physiotherapy alone on pain intensity, disability, Quality of Life (QoL), and treatment effectiveness in patients with Subacromial Pain Syndrome (SAPS). Methods: In this double-blind, parallel Randomized Controlled Trial (RCT), 50 patients with SAPS were randomly assigned into combined (N=25, a single injection 3-6 days before physiotherapy) and physiotherapy alone group (N=25). Pain, disability, QoL, and treatment-effectiveness were measured at preintervention, post-intervention, and 3 and 6-month follow-up with Visual Analog Scale (VAS), Shortened Disability of the Arm, Shoulder, and Hand (Quick-DASH), Shoulder Pain and Disability Index (SPADI) (primary outcome measure), Western Ontario Rotator Cuff (WORC), and Global Rating of Change (GRC) respectively. A 2×4 (group×time) mixed model analysis of variance (ANOVA) was applied for analysis. Results: The ANOVA revealed statistically significant group-in-time interaction for all outcome measures (p-value < 0.05). The independent t-test showed more effectiveness in the combined group at mediumterm, as the mean scores of almost all outcome measures were substantially lesser (p<0.01). Moreover, in short-time, despite a greater number of patients stating "completely recovered" in the combined group, there was no statistically significant difference between groups. Conclusions: Effects of physiotherapy plus corticosteroid injection could be more long-lasting than physiotherapy alone in improving pain intensity, disability, QoL, and treatment effectiveness in patients with SAPS.

Comparing short- and long-term effects of comprehensive physiotherapy (CP) and subacromial corticosteroid injection (SCI) on pain, disability, and quality of life in the patients with subacromial pain syndrome (SAPS). 2 × 4 randomized controlled trial. 50 participants with unilateral SAPS. Random assignment with allocation concealment into two groups labeled as 12 sessions, supervised CP (n = 22) and 1cc triamhexal SCI (n = 25). Visual Analog Scale (VAS), Shoulder Pain and Disability Index (SPADI), shortened Disabilities of Arm, Shoulder and Hand (Quick-DASH), and Western Ontario Rotator Cuff Index (WORC). Outcomes were gathered pre- and post-intervention, with three- and six-month follow-ups. Variance analysis revealed that there was a significant interaction of group-in-time for SPADI and WORC (P <.05) but not for Quick-DASH and VAS (P >.05). The independent t-test analysis showed that the mean scores of all outcome measures in CP group were lesser than SCI group via 6 months (P <.05), except for the VAS (P >.05, mean difference = −0.97, 95% confidence interval −2.11–0.15). CP results in statistically significant and potentially clinically important difference in function and quality of the life at all timeframe. Moreover, there was no between group difference in order to reduce pain. [ABSTRACT FROM AUTHOR]

Previous studies have suggested that weakening of shoulder and scapula muscles have been associated with increased pain, and decreased functional abilities in patients with lateral elbow tendinopathy (LET). To compare the effects of shoulder and scapula muscle training plus conventional physiotherapy with conventional physiotherapy only. A group of 48 patients with LET was randomly allocated into two groups: shoulder and scapula muscle training plus conventional physiotherapy (n = 24), and conventional physiotherapy (n = 24). All patients received 12 sessions of treatment for 4 weeks. Furthermore, both groups were instructed to continue their own exercise program at home until four months after the end of treatment. Pain intensity, grip strength, and functional status were measured preintervention, postintervention, and 4 months after the end of intervention (4-month follow-up). The shoulder and scapula muscle training plus conventional physiotherapy group showed significantly more reduction in pain and greater improvement in functional status compared with conventional physiotherapy group, but there was no significant difference in pain-free grip strength for two groups. Conventional physiotherapy combined with shoulder and scapula muscle training could be more effective in improving the pain and functional abilities of patients with LET compared with conventional physiotherapy only.

Background: the aim of this study is to evaluate the prevalence and effect of depression and anxiety on the shoulder range of motion, as well as the objective and subjective symptoms in patients suffering from frozen shoulder. Methods: Between 2013 and 2014, in a cross-sectional study, we evaluated 120 patients with idiopathic frozen shoulder. We collected the demographic data for each patient and measured shoulder range of motion in four directions in both limbs. All patients filled out visual analog scale (VAS) for pain and the disabilities of the arm, shoulder, and hand (DASH) questionnaires. Both Hamilton anxiety and depression questionnaires were filled out for each patient. Results: A total of 92 patients (77%) with idiopathic frozen shoulder showed symptoms of depression, while only 32 (27%) of them experienced anxiety. Thirty-two patients (27%) showed symptoms of both depression and anxiety. Although elevation and abduction were not affected by depression, internal and external rotations were more restricted among patients who had symptoms of depression. DASH and VAS scores were higher in patients with symptoms of depression. In terms of anxiety, only VAS and DASH were different between two groups. In multivariable analysis, DASH score was correlated with severity of both anxiety and depression symptoms. Conclusion: While there is no definitive relationship between symptoms of depression or anxiety and shoulder range of motion in patients suffering from frozen shoulder, patients who suffer from depression or anxiety experienced increased pain and limb disability.

Background: In surgical treatment of thoracolumbar burst fractures, most authors try to lower the number of vertebrae involved during the surgery. Objectives: The aim of this study was to evaluate the outcome of a medium-segment posterior spinal fixation in these patients. Patients and Methods: We retrospectively reviewed 27 patients (18 male, 9 female) with mean age of 39.4 ± 15.0 years old in a before-and-after study. The mean follow-up period was 38.4 ± 15.6 months. We involved 2 intact above vertebrae and one intact below vertebra, inserting a pedicular screw at the fractured level and supplemented the construct with contralateral infralaminar hook. Clinical and radiologic characteristics were assessed with American spinal injury association (ASIA) scale, oswestry disability index (ODI), visual analogue scale (VAS), and plain radiography. Data analysis was carried out by SPSS version 11.5 software. Results: Mean post traumatic kyphosis was + 15.7° ± 3.3° that was changed to - 8.5° ± 4.3° and +1° ± 4.4° at immediate and last visit after surgery, respectively. Mean loss of correction (LOC) was 9.5° ± 1.9° (P < 0.001). At the most recent follow-up visit, mean ODI and VAS were 15.0 ± 14.4 and 2.4 ± 2.5, respectively and 24 cases (88.9%) declared excellent or good clinical results. At the last follow-up visit, LOC had no significant correlation neither with VAS nor ODI. Conclusions: In surgical treatment of thoracolumbar burst fractures, a medium-segment posterior spinal fixation, although cannot maintain the radiologic reduction of the fractured vertebrae efficiently, is not only associated with acceptable clinical outcome but also spare one lower intact lumbar segment and therefore recommended.

Objective: We were curious about the degree of anxiety and depression and their effect on the quality of life of the caregivers of veterans with spinal cord injury (SCI). Methods: A convenience sample of 72 out of 120 caregiver spouses of veterans with spinal cord injury participated in our study. The Hospital Anxiety and Depression Scale (HADS) were considered as a measure of depression and anxiety. The World Health Organization Quality of Life BREF questionnaire (WHOQOL-BREF) was considered to evaluate the quality of life. To compare the caregivers, we enrolled 74 matched caregiver spouses of patients without spinal cord injury. Results: The average age of the spouses was 44.7±6.5. The average time elapsed from the injury was 26.4±3.1 years. There was a significant difference in all domains of quality of life and depression between the caregivers and the control group, but there was not a significant difference in terms of anxiety. There was a negative correlation between depression and age, level of education and quality of life. Conclusion: Mental care support should be implemented for veterans and their spouses in addition to the provided facilities. [ABSTRACT FROM AUTHOR]

Background: Fractures of the knee account for about 6% of all trauma admissions. While its management is mostly focused on fracture treatment, it is not the only factor that defines the final outcome. Objectives: This study aimed to study objective and subjective outcomes after proximal tibial versus distal femoral fractures in terms of knee instability and health-related quality of life. Patients and Methods: This retrospective, cross-sectional, cohort study was carried out on 80 patients with either isolated proximal tibial (n = 42) or distal femoral (n = 38) fractures, who underwent open reduction and internal fixation. All the fractures were classified based on the Schatzker and AO classification for tibial plateau and distal femoral fractures, respectively. The patients were followed and examined by an orthopedic knee surgeon for clinical assessment of knee instability. In their last follow-up visit, these patients completed a Lysholm knee score and the short-form (SF) 36 health survey. Results: Among the 42 tibial plateau fractures, 25% were classified as Schatzker type 2. Of the 38 distal femoral fractures, we did not find any type B1 or B3 fractures. The overall prevalence of anterior and posterior instability was 42% and 20%, respectively. Medial Collateral Ligament (MCL) and Lateral Collateral Ligament (LCL) injuries were detected clinically in 50% and 28%, respectively. The incidence rates of ligament injuries in tibial plateau fractures were as follows: Anterior Collateral Ligament (ACL) 26%, Posterior Collateral Ligament (PCL) 7%, MCL 24%, and LCL 14%. Medial collateral ligament injury was the most common in the Schatzker type 2 (50% of the injuries). Distal femoral fractures were associated with ACL injury in 16%, PCL in 13%, MCL in 26% and LCL in 14%. However, final knee range of motion (ROM) and function (Lysholm score) were not associated with fracture location. No statistically significant difference was observed between the two groups, except for the valgus stress test at 30°knee flexion, which was more positive in tibial fractures. All eight domains of SF-36 score in the distal femoral and proximal tibial fractures were significantly different from the normal values; however, there were no statistically significant differences between femoral and tibial fracture scores. Conclusions: Although ROM is acceptable in knee joint fractures, instability is common. However, it seems that knee function and quality of life are not associated with the location of the fracture.

Background: This study aimed Persian translation and validation of the hip disability and osteoarthritis outcome score (HOOS) questionnaire., Methods: The study was carried out in two phases. First, we translated the HOOS according to acceptable guidelines. We assessed HOOS content convergent validity on 203 hip osteoarthritis patients using SF-36. Internal consistency was tested using Cronbach's alpha coefficient if each item removed and intraclass correlation coefficient (ICC) for the assessment of test-retest reproducibility., Results: Patients had mean (standard deviation) age of 39 (17). Test-retest ICC in whole was 0.95 ( P = 0.014) showing excellent reliability. ICC was 0.92 for the "pain" subscale ( P = 0.02), 0.81 for the "symptom" subscale ( P = 0.002), 0.81 for the "function of daily living (FDL)" ( P = 0.022), 0.88 for the "function of sports and recreational activities" ( P = 0.006), but it was 0.62 ( P = 0.1) for the "quality of life (QOL)." Cronbach's alpha was 0.92, 0.73, 0.97, 0.86, 0.80, and 0.80 for the pain, symptom, FDL, function of sports, QOL, and stiffness, respectively, showing good to excellent internal consistancy. Having SF-36 for the assessment of convergent validity, there was a strong correlation between total HOOS score and the physical component summary domain of SF-36 ( r = 0.64, P = 0.0001), whereas the t correlation with the mental component summary domain was weak ( r = 0.16, P = 0.04)., Conclusions: The Persian version of the HOOS questionnaire is a valid (regarding physical not mental aspects) and reliable assessment tool in patients with hip osteoarthritis., Competing Interests: There are no conflicts of interest.

Background: In recent decades, the incidence of spinal cord injuries has increased. In a systemic review on epidemiology of traumatic spinal cord injury in developing countries reported 25.5/million cases per year., Objectives: To assess the quality of life (QOL) of the veterans among Iran-Iraq war with chronic spinal cord injuries (SCI) and to evaluate long-term impressions of SCI on their quality of life., Patients and Methods: Fifty-two veterans, all male, with chronic spinal cord injury from Iran-Iraq war (1980-1988) were interviewed and examined. The mean age of veterans at the time of interview was 49.3 years (38 to 80 years). Veterans were assessed by using a 36-item short-form (SF-36), hospital anxiety and depression scale (HADS) and the Barthel index. The presence or absence of pressure sores and spasticity were documented as well., Results: The mean age of veterans at the time of study was 49.3 years. Pearson's correlation test showed that depression and anxiety have a reverse association with mental component summary (MCS) scale and physical component summary (PCS) scale scores, respectively. Regression analysis showed a negative effect of depression and pressure sore on PCS. Moreover, no association was found between the duration of injury and age with quality of life., Conclusions: Lower QOL was found among veterans with chronic SCI. More researches on health-related quality of life (HRQOL) are needed to give us a better understanding of changes in life of patients with SCI and the ways to improve them.
