Effectiveness of a Home-Based Video-Guided Hip Muscle Exercise Program in Elderly Patients Following Bipolar Hemiarthroplasty for Femoral Neck Fracture: A Randomized Controlled Trial

BACKGROUND: Physical therapy after a femoral neck fracture is essential but is limited by poor compliance and incorrect exercise. To improve this, we developed the home-based video-guided music program (HBW-MV) program. We hypothesize that this program will improve functional outcome. STUDY DESIGN AND METHODS: This was a randomized controlled trial from 2023 to 2024 on elderly patients with cementless bipolar hemiarthroplasty after femoral neck fracture. Thirty patients were equally allocated into the intervention group and the control group. Both received pre-discharge physical therapy instructions from an orthopedic trainee. Functional outcomes were assessed using Harris Hip Score (HHS) from two to 12 weeks. Hip strength was measured by a handheld dynamometer. Anxiety and pain were assessed using a visual analog scale. Compliance was assessed by a record table. RESULTS: Both groups showed an increase in HHS at two, six, and 12 weeks postoperatively. The intervention group demonstrated significantly higher HHS compared with the control group at all time points, with mean scores of 49.40±6.10, 65.20±6.09, and 82.30±5.85 versus 39.73±7.80, 53.53±5.84, and 67.67±6.33, respectively (p
