Effects of Lower Limbs Symmetrical Loading on Risk of Fall

Objective: To assess the impact of total hip arthroplasty (THA) on functional outcomes and fall risk in patients with hip osteoarthritis. The objective was to investigate the effectiveness of physical therapy in postoperative rehabilitation and identify fall risk factors to guide fall prevention strategies after THA. Methods: A non-randomized, interventional clinical trial was conducted with 30 patients scheduled for THA. Functional outcomes were evaluated using the Harris Hip Score (HHS), 40-meter fast-paced walk test (40mFPWT), 30-Second Chair Test, and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). Balance and fall risk were assessed using the Single-Leg Standing Test and a posturography device (TETRAX). The Nottingham Health Profile (NHP) was used to measure subjective health status and quality of life. Assessments were performed preoperatively, at 6 weeks postoperatively, and at 3 months postoperatively.
