Low level laser therapy (LLLT) is a relatively new and increasingly popular form of electrotherapy. It is used by physiotherapists in the treatment of a wide variety of conditions including RA despite the lack of scientific evidence to support its efficacy. A randomized, double-blind and placebo-controlled study was conducted to evaluate the efficacy of LLLT. The patient sample consisted of chronic RA patients with active finger joint synovitis. Forty RA patients with involvement of some or all of MCP or PIP joints were recruited. Following random allocation they received either active or placebo laser three times a week for 4 weeks. Measurements were taken prior to entry, after the treatment, 1 month and 3 months at follow-up. The groups were well matched in terms of age, sex, disease duration and severity. Few significant differences were noted in grip strength, duration of morning stiffness, joint tenderness, temperature of inflamed joints, range of movement or pain either within or between groups. Using these irradiation parameters the efficacy of LLLT is ineffective. Low energy laser (LEL) is a widely used treatment for a variety of musculoskeletal disorders although convincing documentation of the effect is missing. We have examined the LEL effect on Rheumatoid Arthritis (RA) in a double blind placebo controlled study. Twenty-two patients completed the study (10 receiving LEL treatment) according to the protocol. A significant effect on pain score was found due to LEL treatment, but when data were corrected for disease variation the effect disappeared. No effect of LEL could be demonstrated on the other assessed variables: grip strength, morning stiffness, flexibility, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP). In conclusion, we did not find that LEL had any clinically relevant effects on RA. Joint protection aims to reduce pain and local inflammation, preserve the integrity of joint structures and improve function. There is evidence that it can improve pain and function in the short term, but the long-term effects are uncertain. This study evaluated the effects of joint protection in early rheumatoid arthritis (RA).
                A randomized, controlled, assessor-blinded trial of duration 1 yr was conducted. Two interventions (both 8 h) were compared: standard arthritis education, including 2.5 h of joint protection education based on typical UK practice; and a joint protection arthritis education programme, using educational-behavioural teaching methods. Assessments were made at entry and 6 and 12 months.
                Sixty-five people with RA attended the joint protection programme and 62 the standard programme. The groups were matched for age (51 and 49 yr), disease duration (21 and 17.5 months) and use of non-steroidal anti-inflammatory drugs and disease-modifying anti-rheumatic drugs. In comparison with the standard group, the joint protection group significantly improved with respect to adherence to the joint protection programme (P=0.001), hand pain (P=0.02), general pain (P=0.05), early morning stiffness (P=0.01), self-reported number of disease flare-ups (P=0.004), visits to the doctor for arthritis (P<0.01), and the AIMS2 (Arthritis Impact Measurement Scales) activities of daily living scale (P=0.04). A trend to improved swollen joint counts was identified (P=0.07). Within-group analyses also showed improvements in arthritis self-efficacy and perceived control. Hand deformity scores continued to increase in both groups.
                We found significant improvements in adherence, pain, disease status and functional ability amongst those attending the joint protection programme. Benefits became more apparent with time, suggesting that joint protection can help slow the progression of the effects of RA over and above the effects of drug therapy. Thirty-six patients with active rheumatoid arthritis were treated for 12 days at the Ein Gedi Spa. The patients were allocated randomly to four study groups. Group 1 (n = 9) was treated with daily baths in the Dead Sea, group 2 (n = 9) was treated with daily sulphur baths, group 3 (n = 10) was treated with a combination of daily Dead Sea bathing and sulphur baths, and group 4 (n = 8) served as a control group. All patients were assessed by a rheumatologist who was blinded to the treatment modalities and group allocation. Clinical parameters assessed included: duration of morning stiffness, 15 m walk time, grip strength, activities of daily living, patient's assessment of disease severity, number of active joints, and the Ritchie articular index. Statistically significant improvement lasting up to 3 months was observed only in the three treatment groups. To evaluate the short term efficacy of a community based physical therapy (PT) program for people with rheumatoid arthritis (RA) through a single blind randomized controlled trial.
                Adults with active RA were referred by their physician for community based PT. Participants were randomized to either an immediate intervention group [experimental group (EG)] or a wait list control group (CG). The intervention was a standardized program of education and exercise consisting of at least 4 visits or 3 h of PT over 6 weeks. Baseline, 6, and 12 week assessments were by a blinded independent assessor. The primary outcome instrument was the Stanford Arthritis Self-Efficacy Scale (SES) and secondary outcome measures included the ACREU Rheumatoid Arthritis Knowledge Questionnaire (KQ) and visual analog scale for pain (VAS). Duration of morning stiffness, grip strength, and tender joint count were also collected at each assessment. Outcome analysis was conducted using analysis of variance.
                Of 150 eligible and randomized participants, 127 completed the study according to protocol. Baseline analysis showed no differences between the EG and CG for demographics, disease status, or other characteristics. At the 6 week assessment, primary outcome analysis for those who completed the protocol identified a mean change (improvement) of 13.5% in the EG and 5.8% in the CG, representing a 7.7% difference in change scores between the 2 groups [F(1,121) = 6.03; p = 0.015]. A statistically significant difference in change scores was also identified for the KQ [F(1,120) = 6.67; p = 0.011], but not for the VAS. Disease status measures did not change, except for duration of morning stiffness, which improved by 68.8 min in the EG and 8.3 min in the CG (F(1,121) = 4.50; p = 0.036].
                Four hours of a community based PT intervention delivered over 6 weeks significantly improved self-efficacy, disease management knowledge and morning stiffness in people with RA. Oral mucositis (OM) is one of the most frequent complications of chemotherapy for which there is no standard therapy; treatment is mostly conservative. This study was conducted to determine whether low-intensity laser therapy (LLLT) can reduce the duration of chemotherapy-induced OM.
                A placebo-controlled randomized trial was carried out using LLLT or placebo (sham treatment). Children and adolescents with cancer receiving chemotherapy or hematopoietic stem-cell transplantation between October 2005 and May 2006 were eligible as soon as they developed OM. Patients received intervention for 5 days. The LLLT group was treated with laser GaAlAs, wavelength (lambda): 830 nm (infrared), power: 100 mW, dose: 4 J/cm, and placebo group underwent sham treatment. The grade of OM was clinically assessed by the National Cancer Institute, Common Toxicity Criteria scale.
                Twenty-one patients developed OM and were evaluable for analysis; 18 (86%) patients had a diagnosis of leukemia or lymphoma and 3(14%) had solid tumors. The mean age was 8.2 (+/-3.1) years. Nine patients were randomized in the laser group and 12 in the placebo-control group. Once OM was diagnosed, the patients had daily OM grading assessments before laser or sham application and thereafter until complete healing of the lesions. On day 7 after OM diagnosis, 1/9 of patients remained with lesions in laser group and 9/12 of patients in the placebo-control group (P=0.029). In the laser group, the mean of OM duration was 5.8+/-2 days and in the placebo group was 8.9+/-2.4 days (P=0.004).
                Our study has shown evidence that laser therapy in addition to oral care can decrease the duration of chemotherapy-induced OM. Our results confirm the promising results observed in adult cancer patients and should encourage pediatric oncologists to use laser therapy as first-line option in children with chemotherapy-induced OM. To assess the efficacy of a cannabis-based medicine (CBM) in the treatment of pain due to rheumatoid arthritis (RA).
                We compared a CBM (Sativex) with placebo in a randomized, double-blind, parallel group study in 58 patients over 5 weeks of treatment. The CBM was administered by oromucosal spray in the evening and assessments were made the following morning. Efficacy outcomes assessed were pain on movement, pain at rest, morning stiffness and sleep quality measured by a numerical rating scale, the Short-Form McGill Pain Questionnaire (SF-MPQ) and the DAS28 measure of disease activity.
                Seventy-five patients were screened and 58 met the eligibility criteria. Thirty-one were randomized to the CBM and 27 to placebo. Mean (S.D.) daily dose achieved in the final treatment week was 5.4 (0.84) actuations for the CBM and 5.3 (1.18) for placebo. In comparison with placebo, the CBM produced statistically significant improvements in pain on movement, pain at rest, quality of sleep, DAS28 and the SF-MPQ pain at present component. There was no effect on morning stiffness but baseline scores were low. The large majority of adverse effects were mild or moderate, and there were no adverse effect-related withdrawals or serious adverse effects in the active treatment group.
                In the first ever controlled trial of a CBM in RA, a significant analgesic effect was observed and disease activity was significantly suppressed following Sativex treatment. Whilst the differences are small and variable across the population, they represent benefits of clinical relevance and show the need for more detailed investigation in this indication. To compare the effect of balneotherapy on physical activity and quality of life as well as the symptoms of pain and stiffness with exercise alone in ankylosing spondylitis (AS) patients.
                A total of 60 patients who had a diagnosis of AS according to the modified New York criteria were included in the study. The patients were randomly assigned to two groups. In Group I (n = 30) the patients received balneotherapy in a therapeutic pool for 30 min once a day for 3 weeks. All patients received instructions on the exercise programme, which they were requested to repeat once a day for 30 min during the study. The patients in this group continued the same exercise programme after the end of the balneotherapy protocol to complete a course of 6 months. In Group II the patients were given the same exercise protocol but did not receive balneotherapy. Patients were evaluated before the start of the study and at 3 weeks and 24 weeks. Evaluation parameters were daily and night pain, morning stiffness, the patient's global evaluation and the physician's global evaluation (according to a scoring system of 1 to 5), the Bath Ankylosing Spondilitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Dougados Functional Index (DFI), tragus-wall distance, chest expansion, modified Shober test (MST), fingertip-fibula head distance, and Nottingham Health Profile (NHP).
                Evaluations were completed in 54 patients in the two groups. Comparison of the groups showed significantly superior results for Group I for parameters of BASDAI, NHP total, pain, physical activity, tiredness and sleep score, patient's global evaluation and the physician's global evaluation at 3 weeks, but only for the parameters of patient's global evaluation and MST at 24 weeks.
                Balneotherapy has a supplementary effect on improvement in disease activity and functional parameters in AS patients immediately after the treatment period. However, in the light of our medium-term evaluation results, we suggest that further research is needed to assess the role of balneotherapy applied for longer durations in AS patients. Extracorporeal shock wave therapy (ESWT) is an increasingly popular therapeutic approach to the treatment of a number of soft tissue complaints. Whilst benefit has been demonstrated in calcific tendinitis, evidence is lacking for benefit in the management of non-calcific rotator cuff disorders.
                To perform a double-blind placebo controlled trial of moderate dose ESWT in chronic lateral epicondylitis.
                Adults with lateral epicondylitis were randomised to receive either active treatment (1500 pulses ESWT at 0.12 mJ/ mm2) or sham therapy, monthly for three months. All were assessed before each treatment and one month after completion of therapy. Outcome measures consisted of visual analogue scores for pain in the day and at night.
                Seventy-five subjects participated and there were no significant differences between the two groups at baseline. The mean duration of symptoms was 15.9 and 12 months in the ESWT and sham groups, respectively. Both groups showed significant improvements from two months. No significant difference existed between the groups with respect to the degrees of change in pain scores over the study period. In the ESWT group the mean (SD, range) pain score was 73.4 (14.5, 38-99) at baseline and 47.9 (31.4, 3-100) at three months. In the sham group the mean (SD, range) pain score was 67.2 (21.7, 12-100) at baseline and 51.5 (32.5, 3-100) at three months. At three months, 50% improvement from baseline was noted in 35% of the ESWT group and 34% of the sham group with respect to pain.
                There appears to be a significant placebo effect of moderate dose ESWT in subjects with lateral epicondylitis but there is no evidence of added benefit of treatment when compared to sham therapy.
LLLT could be considered for short-term treatment for relief of pain and morning stiffness for RA patients, particularly since it has few side-effects. Clinicians and researchers should consistently report the characteristics of the LLLT device and the application techniques used. New trials on LLLT should make use of standardized, validated outcomes. Despite some positive findings, this meta-analysis lacked data on how LLLT effectiveness is affected by four important factors: wavelength, treatment duration of LLLT, dosage and site of application over nerves instead of joints. There is clearly a need to investigate the effects of these factors on LLLT effectiveness for RA in randomized controlled clinical trials.
