BACKGROUND: The purpose of this study aimed to investigate changes in knee pain, muscle activity, range of motion (ROM), balance, gait in 40 patients with bent knee joints who underwent total knee arthroplasty (TKA). This study aimed to evaluate ankle pumping exercise and quadriceps muscle strength exercise using pressure biofeedback to assess changes in knee pain, muscle activity, ROM, balance, gait. METHODS: Forty patients who underwent TKA were randomly assigned to an experimental group or control group. Both groups received 40 mins interventions, three times a week, for a total of 4 weeks. The experimental group received general physical therapy, gait training, quadriceps muscle strength exercise using pressure biofeedback. Conversely, the control group received general physical therapy, gait training, quadriceps muscle strength exercise to the knee joint. RESULTS: In terms of pain levels decreased in both groups however, no significant differences were found between the groups. Muscle activity and ROM showed significant changes between the groups, and a significant difference was observed between the two groups in the post intervention comparison. Balance showed significant changes between the groups, with significant differences observed between the pre and post intervention comparisons. Gait showed significant changes between the groups, with significant differences observed between post intervention comparisons. CONLUSION: The experimental group who underwent TKA and performed ankle pumping exercise in the knee joint and quadriceps muscle strength exercise using pressure biofeedback exhibited improvements in muscle activity, ROM, balance, gait. In the future, it is intended to provide basic data for the treatment of patients with knee joint on quadriceps muscle activity after TKA.
