Eccentric versus concentric isotonic resistance training of quadriceps muscles for treatment of knee osteoarthritis.
Rawal Med J Jan ;46(1):52-5.
Objective: To compare the effect of isotonic eccentric resistance training versus isotonic concentric resistance training for treatment of knee osteoarthritis (KOA). Methodology: A total of 40 obese female patients with KOA (grade 2 and 3) and age between 40 to 60 years were randomized into 2 equal groups. The 1st group of 20 patients followed a physical therapy program of isotonic eccentric resistance training and the second group of 20 patients had physical therapy program of isotonic concentric resistance training for 8 weeks. We used visual analogue scale, knee range of motion, Western Ontario and McMaster University osteoarthritis index (WOMAC) and one repetition maximum test. Results: There was more improvement in isotonic eccentric resistance training when compared to isotonic concentric resistance training. Conclusion: Both resistance trainings played an important role in decreasing pain and stiffness, by improving muscles strength, range of motion, and functional activities of daily living but isotonic eccentric resistance training was more effective. This study emphasizes that both exercises are essential to incorporate in treatment of KOA.
