Introduction: The progression of in!ammation in rheumatoid arthritis (RA) leads to destruction of synovial membrane, joint surface, loss of function and mobility. Comprehensive rehabilitation consists of exercises, modalities, orthoses and occupational therapy.
Goal: The aim of this study was to compare the multi-waved locked system (MLS) laser therapy with low-frequency magnetic "eld (MF) therapy on hand function and quality of life in RA patients.
Methods: The study was conducted among 30 patients with RA. First group (n=15) received ten sessions MLS laser therapy (intensity 50%, 500 Hz, 808 nm, 905 nm), second group (n=15) received ten sessions MF therapy (5-23 Hz, 3-7.5 mT). The intensity of pain was assessed by Visual Analogue Scale, hand function by Brief Michigan Hand Outcome Questionnaire.
Results: Reduction of pain was reported in the MLS laser therapy group, but not in the MF group. In both groups a decrease of swollen joints number (Ritchie Articular Index) was observed. Moreover, improvement of hand function, grip strength and quality of life (Health Assessment Questionnaire) were also observed, especially in MLS laser therapy group.
Conclusion: MLS laser therapy appears to be more e$ective modality, than MF therapy in patients with RA with hand involvement.
