Abstract

ABSTRACT :. Hip hemiarthroplasty is a surgical procedure in which the femoral head is replaced with a prosthesis. Pelvic muscle strength, particularly the gluteus medius muscle, plays a crucial role in stability post-hip hemiarthroplasty but often decreases due to immobilization and pain. The Wii Balance Board is used to measure static balance through the Center of Pressure (COP), while the Timed Up and Go (TUG) test measures dynamic balance with high reliability. Moderate-intensity strengthening exercises (60–80% 1RM) are effective in improving muscle strength, joint stability, and patient functional ability, supporting optimal recovery post-surgery.

This study aims to analyze the comparative effects of moderate-intensity strengthening exercises versus conventional strengthening exercises on balance function post-hip hemiarthroplasty. The study used a randomized control trial design and divided participants into two groups: the moderate-intensity strengthening group and the conventional exercise group. The subjects were post-hip hemiarthroplasty patients at the Medical Rehabilitation Unit of Prof. Dr. R.D. Kandou General Hospital, Manado, who met the inclusion criteria. Subjects were selected using consecutive sampling. The results concluded that moderate-intensity strengthening exercises as a supplementary therapy alongside conventional therapy were proven effective in improving balance function post-hip hemiarthroplasty, with 12 sessions of therapy. Moderate-intensity strengthening exercises are safe for post-hip hemiarthroplasty patients and can be utilized as a non-pharmacological modality to enhance balance function.
