Quadriceps Femoris Muscle Function Characteristics in Women With Early Knee Osteoarthritis: A 2-Year Exercise Therapy Study

摘要

1. Radiographic progression of knee OA is related to the decrease in QF muscle function in women with early knee osteoarthritis. 2. Increase in voluntary activation of QF muscle compensates the decrease of isokinetic power output and maintains QF muscle function.
