Introduction: Osteoarthritis (OA), the most common form of arthritis, is considered the main cause of pain and disability in the elderly. Objective: To evaluate the effect of systematic muscle strength training on functional performance and quality of life in individuals with knee OA. Methods: Subjects with knee OA (n = 27, 46 - 76 years) completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Medical Outcomes Short-Form 36-item Health Survey (SF-36), and visual analog scale (VAS) questionnaires, musculoskeletal assessments, and 10-repetition maximum and timed 10-meter walk tests both before and after training. The training consisted of an exercise resistance program and stretches for 12 weeks (three sessions of 80 each per week). Results: Twenty-two subjects completed the training. Reduced overall scores and WOMAC physical function indicated improved functional performance (p < 0.001) as well as increased gait speed (p < 0.001). The perception of pain decreased after training, as evidenced by the VAS, WOMAC pain domain, and SF-36 scores (p < 0.001). Quality of life improvements occurred primarily in the areas of pain, functional capacity, and SF-36 physical aspects. No change in body mass index was noted (p = 0.93). Conclusion: Our results indicate that the combination of resistance training for the quadriceps, gluteus, and abdominal muscles could be a viable alternative to improving functionality and quality of life in patients with knee OA. However, more studies are necessary to confirm our findings.Downloads
