Muscle Isometric Contraction for the Treatment of Knee Osteoarthritis

Firstly, they received the same health education as the control group. Subsequently, the elderly individuals with Knee Osteoarthritis (KOA) underwent five interventions per week targeting the quadriceps femoris muscle. For each intervention, the quadriceps performed an isometric contraction and relaxation for 1 second each. The intervention consisted of 10 repetitions per set of Muscle Isometric Contraction (MIC), guided by a rhythmic timer, for a total of 10 sets, with a 30-second rest between sets. The entire intervention lasted for 16 weeks.

Subsequently, the elderly individuals with Knee Osteoarthritis (KOA) underwent five interventions per week targeting the quadriceps femoris muscle. For each intervention, the quadriceps performed an isometric contraction and relaxation for 1 second each. The intervention consisted of 20 repetitions per set of Muscle Isometric Contraction (MIC), guided by a rhythmic timer, for a total of 10 sets, with a 30-second rest between sets. The entire intervention lasted for 16 weeks.
