This study evaluated the synergistic effects of ultrasound (US) and low-level laser therapy (LLLT) with or without therapeutic exercises (TE) in women with knee osteoarthritis. Forty-two Caucasian women with knee osteoarthritis were allocated into three groups: (1) the placebo group who did not perform TE, but the prototype without emitting light or ultrasonic waves was applied, (2) the US + LLLT group in which only the prototype was applied and (3) the TE + US + LLLT group that performed TE before the prototype was applied. However, 35 women completed the full clinical trial. Pressure pain thresholds (PPT) using an algometer and functional performance during the sit-to-stand test were carried out. The average PPT levels increased for US + LLLT (41 ± 9 to 54 ± 15 N, p < 0.01) and TE + US + LLLT (32 ± 8 to 45 ± 9 N, p < 0.01) groups. The number of sit-to-stands was significantly higher for all groups. However, the change between pre-treatment and post-treatment (delta value) was greater for the US + LLLT (4 ± 1) and TE + US + LLLT groups (5 ± 1) than for the placebo group (2 ± 1) with a significant intergroup difference (p < 0.05). This study showed reduced pain and increased physical functionality after 3 months of US + LLLT with and without TE.

Objective: Reduced function persists for many patients after total knee arthroplasty (TKA). Inflammation is part of osteoarthritis' pathophysiology, and surgery induces a marked inflammatory response. We therefore wanted to explore the role of inflammation in long-term recovery after TKA, and thus conducted this secondary analysis of our randomized controlled trial (RCT) of physical rehabilitation ± progressive strength training (PST). We aimed to investigate whether (1) inflammation is associated with functional performance, knee-extension strength, and knee pain before TKA; (2) PST affects inflammation, and the inflammatory state over time; (3) baseline or surgery-induced inflammation modifies the effect of rehabilitation ± PST on change in 6-min walk test (Δ6MWT); and (4) baseline or surgery-induced inflammation is associated with Δ6MWT following TKA., Design: In the primary trial report's per-protocol analysis, 72/82 patients were included. Sixty had ≥1 blood sample before and after TKA, and were included in this secondary analysis. Inflammation was measured by interferon γ-inducible protein (IP)-10, soluble urokinase plasminogen activator receptor (suPAR), interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF)-α at baseline; day 1, week 4, 8, and 26 after TKA., Results: At baseline, suPAR (P = 006) was negatively associated with 6MWT. Neither baseline nor surgery-induced inflammation modified the response to rehabilitation ± PST. Only surgery-induced IL-10 was associated with Δ6MWT 26 weeks-baseline (P = 0.001), also adjusted for 6MWT baseline , age, sex and body mass index (BMI)., Conclusion: In this secondary analysis, only increased surgery-induced IL-10 response was associated with decreased long-term functional performance after TKA. The importance of controlling the surgery-induced immune response remains to be investigated further., Trial Identification: NCT01351831., (Copyright © 2017 Osteoarthritis Research Society International.

Purpose: Low-dose external beam radiotherapy (ED-EBRT) is frequently used in the therapy of refractory greater trochanteric pain syndrome (GTPS). As studies reporting treatment results are scarce, we retrospectively analyzed our own patient collectives., Patients and Methods: In all, 60 patients (74 hips) received LD-EBRT (6 × 0.5 Gy in 29 hips, 6 × 1 Gy in 45). The endpoint was the patient's reported subjective response to treatment. The influence of different patient and treatment characteristics on treatment outcome was investigated., Results: At the end of LD-EBRT, 69% reported partial remission, 4% complete remission, no change 28%. A total of 3 months later (n = 52 hips), the results were 37, 33, and 30% and 18 months after LD-EBRT (n = 47) 21, 51, and 28%. In univariate analysis "inclusion of the total femoral head into the PTV" and "night pain before LD-EBRT" were correlated with symptom remission at the end of LD-EBRT, while "initial increase in pain during LD-EBRT" was significantly associated with treatment failure. In multivariable modeling "initial increase in pain" was identified as a risk factor for treatment failure (p = 0.007; odds ratio [OR] 0.209; 95% confidence interval [CI] 0.048-0.957), while "night pain" was an independent factor for remission (p = 0.038; OR 3.484; 95% CI 1.004-12.6). Three months after LD-EBRT "night pain" and "inclusion of the complete femoral neck circumference into the PTV" were predictive for remission., Conclusion: LD-EBRT represents a useful treatment option for patients suffering from GTPS. Three months after therapy two-thirds of the patients reported a partial or complete symptom remission. Especially patients who suffered from nocturnal pain seemed to benefit. Treatment appeared to be more effective when the entire circumference of the femoral neck was encompassed.

This study aimed to compare the effectiveness of the combined low-level laser therapy (LLLT) and passive stretching with combined placebo LLLT laser and the same passive stretching exercises in patients suffering from Αnkylosing spondylitis. Forty-eight patients suffering from Αnkylosing spondylitis participated in the study and were randomized into two groups. Group A (n = 24) was treated with a λ = 820 Ga-Al-As laser CW, with power intensity = 60 mW/cm(2), energy per point in each session = 4.5 J, total energy per session = 27.0 J, in contact with specific points technique, plus passive stretching exercises. Group B (n = 24), received placebo laser plus the same passive stretching exercises. Both groups received 12 sessions of laser or placebo within 8 weeks; two sessions per week (weeks 1-4) and one session per week (weeks 5-8). Pain and function scales were completed before the treatment, at the end of the fourth and eighth week of treatment, and 8 weeks after the end of treatment (follow-up). Group A revealed a significant improvement after 8 weeks of treatment in all pain and function scales. At 8-week follow-up, the improvement remained only for the pain, while for all other function outcomes the differences were not statistically significant. The results suggested that after an 8-week treatment and after a follow-up, the combination of LLLT and passive stretching exercises decreased pain more effectively than placebo LLLT along with the same passive stretching exercises in patients with Αnkylosing spondylitis. Future studies are needed to establish the relative and absolute effectiveness of the above protocol.

Background and Purpose: The purpose of this article is to summarize the updated DEGRO consensus S2e guideline recommendations for the treatment of benign painful degenerative skeletal disorders with low-dose radiotherapy., Materials and Methods: This overview reports on the role of low-dose radiotherapy in the treatment of enthesiopathies (shoulder syndrome, trochanteric bursitis, plantar fasciitis, and elbow syndrome) and painful arthrosis (knee, hip, hand, and finger joints). The most relevant aspects of the DEGRO S2e Consensus Guideline Radiation Therapy of Benign Diseases 2014 regarding diagnostics, treatment decision, dose prescription as well as performance of radiotherapy and results are summarized., Results: For all indications mentioned above, retrospective and some prospective analyses have shown remarkable effects in terms of pain relief. Nevertheless, the Level of Evidence (LoE) and the Grade of Recommendation (GR) vary: LoE 1b-4 and GR A-C., Conclusion: Low-dose radiotherapy for painful degenerative skeletal disorders is effective in the majority of the patients and therefore it may be a reasonable therapeutic alternative when simple and non-invasive methods have been used without persistent success. For all discussed entities, single fraction doses of 0.5-1.0 Gy and total doses of 3.0-6.0 Gy/series applied with 2-3 fractions per week are recommended.

The aim of this study was to investigate the effect of low-level laser therapy (LLLT) on short-term and long-term joint pain, synovitis, anabolic, and catabolic factors in the cartilage of a rabbit model with progressive osteoarthritis (OA) induced by anterior cruciate ligament transection (ACLT). A total of 160 New Zealand white rabbits were randomly assigned into two groups (ACLT group and LLLT group). All rabbits received ACLT surgery, and 2-, 4-, 6-, and 8-week treatment after the surgery, with 20 rabbits being tested biweekly over every study period. The LLLT group received LLLT with a helium-neon (He-Ne) laser (830 nm) of 1.5 J/cm(2) three times per week, and the ACLT group received placebo LLLT with the equipment switched off. Long-term and short-term pain was tested via weight-bearing asymmetry; synovitis was assessed histologically; and knee joint cartilage was evaluated by gross morphology, histology, and gene expression analysis of anabolic and catabolic factors. The histological assessment of pain and synovitis showed that at least 6-week intermittent irradiation of LLLT could relief knee pain and control synovium inflammation. Gross morphologic inspection and histological evaluation showed that 6 weeks of LLLT could decrease cartilage damage of medical femoral condyle and 8 weeks of LLLT could decrease cartilage damage of medical and lateral femoral condyles and medical tibial plateau. Gene expression analysis revealed two results: At least 6 weeks of LLLT could decrease production of catabolic factors, for example, interleukin 1β (IL-1β), inducible nitric oxide synthase (iNOS), and MMP-3, and slow down the loss of anabolic factors, mainly TIMP-1. Eight weeks of LLLT treatment could slow down the loss of collagen II, aggrecan, and anabolic factors, mainly transforming growth factor beta (TGF-β). The study suggests that LLLT plays a protective role against cartilage degradation and synovitis in rabbits with progressive OA by virtue of the regulation of catabolic and anabolic factors in the cartilage.

Background and Purpose: To evaluate the long-term efficacy of pain reduction by two dose fractionation schedules used for low-dose radiotherapy of painful elbow syndrome., Patients and Methods: Between February 2006 and February 2010, 199 evaluable patients were recruited for this prospective trial. All patients received low-dose orthovoltage radiotherapy. One course consisted of 6 fractions in 3 weeks. In the case of insufficient pain remission after 6 weeks, a second course was administered. Patients were randomly assigned to one of two groups to receive single doses of either 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before radiotherapy, as well as immediately after (early response), 6 weeks after (delayed response) and approximately 3 years after (long-term response) completion of radiotherapy using a questionnaire-based visual analogue scale (VAS) and a comprehensive pain score (CPS)., Results: Median follow-up was 35 months (range 9-57 months). The overall early, delayed and long-term response rates for all patients were 80, 90 and 94 %, respectively. The mean VAS scores before treatment and those for early, delayed and long-term response in the 0.5- and 1.0-Gy groups were 59.6 ± 20.2 and 55.7 ± 18.0 (p = 0.46); 32.1 ± 24.5 and 34.4 ± 22.5 (p = 0.26); 27.0 ± 27.7 and 23.5 ± 21.6 (p = 0.82) and 10.7 ± 15.0 and 21.5 ± 26.9 (p = 0.12), respectively. The mean CPS values before treatment and those for early, delayed and long-term response were 8.7 ± 2.9 and 8.1 ± 3.1 (p = 0.21); 4.5 ± 3.2 and 5.0 ± 3.4 (p = 0.51); 3.9 ± 3.6 and 2.8 ± 2.8 (p = 0.19) and 1.5 ± 2.3 and 2.4 ± 3.5 (p = 0.27), respectively. No significant differences in the quality of the long-term response were found between the 0.5- and 1.0-Gy arms (p = 0.28)., Conclusion: Low-dose radiotherapy is an effective treatment for the management of benign painful elbow syndrome. For radiation protection reasons, the dose for a radiotherapy series should not exceed 3.0 Gy.

Background and Purpose: The goal of the present study was to evaluate the efficacy of two different dose-fractionation schedules for radiotherapy (RT) of patients with painful elbow syndrome., Patients and Methods: Between February 2006 and February 2010, 199 consecutive evaluable patients were recruited for this prospective randomized trial. All patients received RT in orthovoltage technique. One RT course consisted of 6 single fractions/3 weeks. In case of insufficient remission of pain after 6 weeks a second radiation series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before, right after, and 6 weeks after RT by a visual analogue scale (VAS) and a comprehensive pain score (CPS)., Results: The overall response rate for all patients was 80% direct after and 91% 6 weeks after RT. The mean VAS values before, after and 6 weeks after treatment for the 0.5 and 1.0 Gy groups were 59.6 ± 20.2 and 55.7 ± 18.0 (p = 0.463), 32.1 ± 24.5 and 34.4 ± 22.5 (p = 0.256), and 27.0 ± 27.7 and 23.5 ± 21.6 (p = 0.818). The mean CPS before, after, and 6 weeks after treatment was 8.7 ± 2.9 and 8.1 ± 3.1 (p = 0.207), 4.5 ± 3.2 and 5.0 ± 3.4 (p = 0.507), 3.9 ± 3.6 and 2.8 ± 2.8 (p = 0.186), respectively. No statistically significant differences between the two single dose trial arms for early (p = 0.103) and delayed response (p = 0.246) were found., Conclusion: RT is an effective treatment option for the management of benign painful elbow syndrome. For radiation protection reasons the dose for a RT series is recommended not to exceed 3.0 Gy.

Background: Laser therapy has been proposed as a physical therapy for musculoskeletal disorders and has attained popularity because no side effects have been reported after treatment. However, its true effectiveness is still controversial because several clinical trials have reported the ineffectiveness of lasers in treating pain., Methods: In this systematic review, we investigate the clinical effectiveness of low-level laser therapy (LLLT) on joint pain. Clinical trials on joint pain satisfying the following conditions are included: the laser is irradiated on the joint area, the PEDro scale score is at least 5, and the effectiveness of the trial is measured using a visual analogue scale (VAS). To estimate the overall effectiveness of all included clinical trials, a mean weighted difference in change of pain on VAS was used., Results: MEDLINE is the main source of the literature search. After the literature search, 22 trials related to joint pain were selected. The average methodological quality score of the 22 trials consisting of 1014 patients was 7.96 on the PEDro scale; 11 trials reported positive effects and 11 trials reported negative effects. The mean weighted difference in change of pain on VAS was 13.96 mm (95% CI, 7.24-20.69) in favor of the active LLLT groups. When we only considered the clinical trials in which the energy dose was within the dose range suggested in the review by Bjordal et al. in 2003 and in World Association for Laser Therapy (WALT) dose recommendation, the mean effect sizes were 19.88 and 21.05 mm in favor of the true LLLT groups, respectively., Conclusions: The review shows that laser therapy on the joint reduces pain in patients. Moreover, when we restrict the energy doses of the laser therapy into the dose window suggested in the previous study, we can expect more reliable pain relief treatments.

Objective: To investigate the effects of short-term light therapy with 890-nm radiation on pain, physical activity, and postural stability in patients with knee osteoarthritis (OA)., Design: A double-blind, randomized, placebo-controlled study., Setting: Rehabilitation clinic., Participants: Women (n=62) and men (n=10) with a mean age of 61.2 years (range, 40-88y). All patients fulfilled the combined clinical and radiographic criteria for knee OA as established by the American College of Rheumatology, and all had obtained a Kellgren-Lawrence score of 2 or more., Interventions: Participants received 6 sessions, lasting 40 minutes each, of active or placebo radiation treatment over the knee joints for 2 weeks (wavelength, 890nm; radiant power output, 6.24W; power density, 34.7mW/cm(2) for 40 minutes; total energy, 41.6J/cm(2) per knee per session)., Main Outcome Measures: Participants were assessed weekly over 4 weeks using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for pain, stiffness, and physical function. Physical activity (timed stair climbing, 10-m fast-speed walking, and chair-rising time) and postural stability (using the postural stability evaluation system) were also assessed. The pain score on WOMAC was the primary outcome variable. Data were analyzed by repeated-measures analysis of covariance., Results: Compared with baseline, no significant improvement was observed between groups for pain (P=.546), stiffness (P=.573), or physical function (P=.904). No significant improvement was noted for physical activity including the 10-m fast-speed walking time (P=.284), stair-climbing time (P=.202), stair-descending time (P=.468), chair-rising time (P=.499), or postural stability (P=.986) at the 4 follow-up assessments. Follow-up assessments were conducted after 1 week of treatment (thus, after 3 treatments); after 2 weeks of treatment (thus, after 6 treatments); and 1 and 2 weeks, respectively, after treatment was terminated. Although we found a significant time effect for the 10-m fast-speed walking time (P<.001) in the 2 groups, and a significant group effect in the improvement of stair-climbing time in the treatment group (P=.032), the group × time interaction effects were not significant., Conclusions: Short-term 890-nm radiation therapy for patients with knee OA provided no beneficial effect in improving pain, physical activity, and postural stability., (Copyright © 2012 American Congress of Rehabilitation Medicine.

Objective:   Radiofrequency neurotomy is a recognized treatment for cervical zygapophysial joint pain. In several studies, the method has provided complete pain relief in 60-70% of the patients for approximately 9 months. The validated technique has the disadvantage of procedural times of 2-4 hours because several lesions are performed to take into account the variable nerve course. We tested the hypothesis that ultrasound localization of the nerves would enable us to reduce the number of lesions performed, while reaching the benchmark of at least 80% pain relief in 80% of patients with a median duration of 35 weeks, as achieved by a previous investigation using the standard method., Interventions:   We prospectively studied 15 consecutive patients with diagnosed cervical zygapophysial joint pain. They were treated using a shortened radiofrequency procedure under fluoroscopic control, based on previous ultrasound localization of the joint supplying nerves, with only two thermal lesions performed per nerve. Successful treatment was defined as at least 80% pain relief in the visual analog scale as compared with pretreatment. Follow-up was performed until 12 months after treatment., Results:   Of the 15 patients, 14 were successfully treated (93%, 95% confidence interval [CI] 80-100%) with a median time of pain relief of 44 weeks. At 6 and 12 months, 13 (87%, 95% CI 70-100%) and 6 patients (40%, 95% CI 15-65%) reported successful treatment, respectively. The median duration of the procedure was 35 minutes., Conclusion:   In patients with cervical zygapophysial joint pain, radiofrequency denervation according to a shortened protocol based on ultrasound localization of the nerves reached the benchmark of the standard technique., (Wiley Periodicals, Inc.)

Recurrent haemarthroses often lead to chronic synovitis in patients with haemophilia and von Willebrand disease. Radioactive synovectomy with yttrium-90 (⁹⁰Y) citrate is frequently used to treat this complication, usually with good results. Since 2006, the Nuclear Energy Research Institute (IPEN, Sao Paulo, Brazil) has produced hydroxyapatite particles labelled with ⁹⁰Y for radioactive synovectomy. The aim of this study was to compare the results achieved by both forms of ⁹⁰Y in the treatment of haemophilic synovitis. We included 221 joints from 136 patients (age range: 6-20 years), treated by one of the two radiopharmaceuticals, at the Hemocenter of Mato Grosso, Brazil. The outcomes analysed were the annual frequency of haemarthrosis, articular pain and joint range of motion before and 1 year after RS. Similar results were achieved regardless of whether ⁹⁰Y hydroxyapatite or ⁹⁰Y citrate was used, and results were independent of the joint type, age, gender, radiologic stage and presence of inhibitors. ⁹⁰Y hydroxyapatite appears to be equivalent to the reference product ⁹⁰Y citrate in the treatment of chronic synovitis associated with bleeding disorders., (© 2011 Blackwell Publishing Ltd.)

Background and Purpose: After a patterns-of-care study (PCS) in 2003/2004 addressing benign disorders in general, the German Cooperative Group on Radiotherapy for Benign Diseases (GCG-BD) conducted several multicenter cohort studies including the use of radiotherapy (RT) in painful gonarthrosis (GNA)., Material and Methods: From 2006 to 2008, a PCS for GNA was conducted in all German RT institutions using a standardized structured questionnaire. Patient accrual, patient number, pretreatment, pain record, treatment indications, RT technique, and target volume concepts for painful GNA were assessed. In addition, the long-term functional and subjective outcomes were evaluated., Results: 238/248 institutions (95.9%) returned the questionnaire: 50 (21%) reported no clinical experience with RT in GNA, while 188 (79%) institutions treated 4,544 patients annually (median 15; range one to 846 cases per institution). Indications for treatment were acute pain symptoms in 18.9%, chronic pain in 95.3%, and treatment-refractory pain in 81.1%. The median total dose was 6 Gy (range 3-12 Gy), with a median single dose of 1 Gy (0.25-3 Gy). 40.4% of the institutions applied two fractions and 51.4% three fractions weekly. RT was delivered with orthovoltage units (25%), linear accelerators (79.6%), and cobalt-60 units (8.3%). 42 institutions evaluated the long-term clinical outcome in a total of 5,069 cases. Median pain reduction for at least 3 months was reported in 60% (5-100%), median pain reduction for at least 12 months in 40% (10-100%), and median persistent pain reduction in 27.8% (10-85%) of the treated patients. In 30% of patients (7-100%), a second RT series was applied for inadequate pain response or early pain recurrence. No radiogenic acute or chronic side effects were observed., Conclusion: This PCS comprises the largest number of cases reported for RT in painful and refractory GNA. Despite variations in daily RT practice, high response and low toxicity for this treatment in a very large number of painful and refractory GNA cases renders low-dose RT an effective conservative therapy which can be applied prior to surgical procedures.

We present a case supporting the use of radiation therapy for palliation of joint pain associated with acute myelogenous leukemia. Prior to radiation therapy to the affected joints, and despite standard pain management, this patient was entirely bedridden and in significant pain. Following radiation, she was able to participate in physiotherapy with minimal to no pain until her death several weeks later. A brief literature review of joint involvement in acute myelogenous leukemia is discussed.

Objectives: The aim of this study was to evaluate the efficacy of a systemic application of rhenium-186 hydroxyethylidenediphosphonate (Re HEDP) for pain treatment in patients with hemophilic arthropathies., Methods: Twelve patients with hemophilic arthropathy with at least 3 involved joints with persistent pain were included in this prospective study. A single dose of 15 mCi (555 MBq) Re HEDP was administered intravenously. Before and 12 weeks after treatment, pain assessment was performed using the visual analog scale (VAS). The pain status assessment included the general status, pain of all joints affected, and pain of the 3 mostly involved joints. Furthermore, quality of life was assessed., Results: With regard to the 3 most involved joints, an improvement of the pain symptoms in 25 of 36 (69.4%) joints was observed. With regard to all involved joints a median of 3 joints per patient improved after Re HEDP therapy. General pain status after treatment was 2.0 VAS points lower as compared with pretreatment. The total number of involved joints remained unchanged in 7 patients, increased in 1 patient, and decreased in the remaining 4 patients., Conclusions: The results of this study show an improvement of the pain symptoms of the involved joints 12 weeks after therapy with Re HEDP in patients with hemophilic arthropathy. The only moderate success regarding a reduction of the total number of involved joints is by the fact that despite this improvement most affected joints remained still painful on a lower level after the therapy or due to newly affected joints not painful before initiation of the radionuclide therapy.

Objectives: The aim of this study was to examine the use of radioactive radon therapy among persons with arthritis, and to explore their perceptions of risk versus benefit in using this therapy., Design: This was a qualitative study based on loosely-structured and open-ended interviews, which were then analyzed for themes and patterns., Setting: Participants in the study were recruited over a period of 5 years from clients of a radon health mine in southwestern Montana., Results: Sixty-two mine clients were interviewed, consisting of 36 women and 26 men, ranging in age from 60 to 92 years. Participants believed that radon therapy was an acceptable choice of treatment for arthritis. Perceived benefits of such therapy included more effective pain relief, avoidance of medication side-effects, lower cost, and increased quality of life. The possible future risk of lung cancer from radon exposure was seen as minimal when compared to the perceived benefits., Conclusions: Fear about radon and its possible health risks seemed to have little influence on the decision-making process for the study subjects.

A total of 143 patients suffering various musculoskeletal disorders including rheumatoid arthritis, arthritis, osteoporosis, and post-surgical discomfort were subjected to ELF magnetic treatments using the Seqex device. A clear trend in pain reduction was observed over the 10 treatment regimen as well as a stabilization of relevant lab tests, including cholesterol level and blood pressure. Improvements were also noted in posturometric footboard tests. An additional 20 patients with various neuromuscular difficulties were treated with Seqex as well as magentic "concentrators" for periods ranging from 3 to 10 treatments. Similar improvements in pain reduction were observed in this smaller group.

Objective: This case report describes the treatment of a patient with arthralgia of the temporomandibular joint (TMJ) caused by disc displacement., Background Data: The goal of the treatment of TMJ arthralgia is to decrease pain by promotion of the musculoskeletal system's natural healing ability., Methods: This report describes the complex treatment of TMJ arthralgia. Low-level laser therapy (LLLT) was chosen for its antiinflammatory and analgesic effects. Laser therapy was carried out using the GaAlAs diode laser with an output power of 400 mW, emitting radiation with a wavelength of 830 nm, and having energy density of 15 J/cm2; the laser radiation was applied by contact mode on four targeted spots in 10 sessions. Physiotherapy was recommended to this patient to prevent the injury of intraarticular tissue caused by incorrect movement during opening of the mouth. Splint stabilization and prosthetic treatment were used to reduce overloading of the TMJ, resulting from unstable occlusion and to help repositioning of the dislocated disc., Results: Five applications of LLLT led to decrease of pain in the area of the TMJ on the Visual Analog Scale, from 20 to 5 mm. The anti-inflammatory effect of the laser was confirmed by thermographic examination. Before treatment, the temperature differences between the areas of the normal TMJ and TMJ with arthralgia was higher than 0.5 degrees C. However, at the conclusion of LLLT, temperatures in the areas surrounding the TMJ were equalized., Conclusion: This study showed the effectiveness of complex non-invasive treatment in patients with arthralgia of the TMJ. The analgesic and anti-inflammatory effects of LLLT were confirmed by infrared thermography.

We investigated if low level laser therapy (LLLT) of the joint capsule can reduce pain in chronic joint disorders. A literature search identified 88 randomised controlled trials, of which 20 trials included patients with chronic joint disorders. Six trials were excluded for not irradiating the joint capsule. Three trials used doses lower than a dose range nominated a priori for reducing inflammation in the joint capsule. These trials found no significant difference between active and placebo treatments. The remaining 11 trials including 565 patients were of acceptable methodological quality with an average PEDro score of 6.9 (range 5-9). In these trials, LLLT within the suggested dose range was administered to the knee, temporomandibular or zygapophyseal joints. The results showed a mean weighted difference in change of pain on VAS of 29.8 mm (95% CI, 18.9 to 40.7) in favour of the active LLLT groups. Global health status improved for more patients in the active LLLT groups ( relative risk of 0.52; 95% CI 0.36 to 0.76). Low level laser therapy with the suggested dose range significantly reduces pain and improves health status in chronic joint disorders, but the heterogeneity in patient samples, treatment procedures and trial design calls for cautious interpretation of the results.

Objective: To investigate and compare the effects of radiation synovectomy of various joints in a rheumatological practice., Methods: Consecutive patients referredfor radiation synovectomy to Medical Center Alkmaarfrom 1993 till 1996 were analyzed (n = 138). Patients had to have persistent arthritis despite at least two intra-articular glucocorticoid injections with 20 mg triamcinolone hexacetonide. The knees were treated with 185 MBq Yttrium-90; shoulders, elbows, wrists, hips and talocrural joints received 185 MBq Rhenium-186 and meta-carpophalangeal joints and proximal interphalangeal joints 37 MBq Erbium-169. The radionuclide injection was followed by injection of 20 mg triamcinolone in order to prevent flare-up of synovitis (due to chemical irritation) and needle-track burn. The clinical effect was assessed by evaluating VAS pain (0-10 point scale), functional disability, tenderness and swelling of the treated joint and patient's and physician's global assessments of the effect of therapy (each on a 4-point scale)., Results: The overall success rate for radiation synovectomy one year after treatment was 70% with a significant improvement in the variables VAS pain, functional disability and joint tenderness and swelling, when compared to baseline values (p < 0.000001). Moderate to considerable satisfaction of patients and physicians one year after treatment was found for > 50% of cases. Wrists and shoulders were the joints with highest success rate of treatment, followed by the elbows. Lowest success rates were found for hips and ankles. In RA treatment was effective in 76% of cases whereas patients with OA exhibited a success rate of 50%. In RA all treated joints, except the ankles, exhibited a success rate of > or = 75%. No short-term clinical adverse side effects were noted., Conclusion: Radiation synovectomy seems to be a successful treatment for persistent arthritis when other therapeutic modalities have failed.

Objective: The semiconductor or laser diode (GaAs, 904 nm) is the most appropriate choice in pain reduction therapy., Summary Background Data: Low-power density laser acts on the prostaglandin (PG) synthesis, increasing the change of PGG2 and PGH2 into PG12 (also called prostacyclin, or epoprostenol). The last is the main product of the arachidonic acid into the endothelial cells and into the smooth muscular cells of vessel walls, that have a vasodilating and anti-inflammatory action., Methods: Treatment was performed on 372 patients (206 women and 166 men) during the period between May 1987 and January 1997. The patients, whose ages ranged from 25 to 70 years, with a mean age of 45 years, suffered from rheumatic, degenerative, and traumatic pathologies as well as cutaneous ulcers. The majority of patients had been seen by orthopedists and rheumatologists and had undergone x-ray examination. All patients had received drug-based treatment and/or physiotherapy with poor results; 5 patients had also been irradiated with He:Ne and CO2 lasers. Two-thirds were experiencing acute symptomatic pain, while the others suffered long-term pathology with recurrent crises. We used a pulsed diode laser, GaAs 904 nm wavelength once per day for 5 consecutive days, followed by a 2-day interval. The average number of applications was 12. We irradiated the trigger points, access points to the joint, and striated muscles adjacent to relevant nerve roots., Results: We achieved very good results, especially in cases of symptomatic osteoarthritis of the cervical vertebrae, sport-related injuries, epicondylitis, and cutaneous ulcers, and with cases of osteoarthritis of the coxa., Conclusions: Treatment with 904-nm diode laser has substantially reduced the symptoms as well as improved the quality of life of these patient, ultimately postponing the need for surgery.

A patient with florid hypertrophic pulmonary osteoarthropathy (HPOA) associated with metastatic nasopharyngeal carcinoma is presented. Despite the presence of metastatic disease in the thorax and in bone, the patient's main symptom was severe pain from the HPOA, which was temporarily relieved by chemotherapy. Her disease subsequently progressed during chemotherapy and the pain became resistant to conventional treatment, including high dose morphine, non-steriodal anti-inflammatory agents and steriods. It was only with local radiation to the involved joints that the pain could be controlled. Our patient demonstrates that local radiotherapy is an option for the palliation of extreme HPOA.

Laser therapy has been found effective in the management of pain associated with rheumatoid and degenerative joint arthritis and disease. The efficacy of mid-laser therapy has been tested specifically on patients with degenerative joint disease (DJD) involving the temporomandibular joint (TMJ). The following controlled clinical study was designed to test the efficacy of mid-laser therapy to placebo therapy in the reduction of pain associated with TMJ disorders specific to arthralgic DJD.

This research tries to determine the difference between two forms of physical therapy, as regards their efficiency, in treating the painful shoulder syndrome. They are: laser treatment, representing modern technology, and cryotherapy, an old and traditional form of treatment. The research comprised 60 patients, divided in two groups of 30 patients each. One group was treated by the cryotherapy procedures, the other by ten laser treatments, both having in addition individual therapeutic exercise for each patient. The difference in efficiency regarding both procedures were observed on the basis of objective measurable parameters (abduction, anteflexion, retroflexion, external and internal rotation, the distance vertebrae prominens and styloid radius) as well as in view of anamnestic terms (pain both at rest and in motion) recorded before the treatment started and after the application of ten therapeutic procedures. The statistic results of data processing showed no significant difference in efficiency, regarding the objective parametres, between the two procedures treating painful shoulder syndrome. Nevertheless, laser treatment proved more efficient in reducing pain. In assessing the efficiency of both treatments there is a slight discrepancy as to the outcome between patients and the researcher: the patients found the laser treatment more efficient than cryotherapy, while the researcher's evaluation was equal both procedures.
