OBJECTIVES: To compare the effectiveness of a short-term leg-strengthening exercise program with that of attentional control on improving strength, walking abilities, and function 1 year after hip fracture. DESIGN: Randomized controlled pilot study. SETTING: Patients' homes. PARTICIPANTS: Community-dwelling older adults (n=26) 6 months after hip fracture at baseline. INTERVENTION: Exercise and control participants received interventions from physical therapists twice a week for 10 weeks. The exercise group received high-intensity leg-strengthening exercises. The control group received transcutaneous electrical nerve stimulation and mental imagery. MEASUREMENTS: Isometric force production of lower extremity muscles, usual and fast gait speed, 6-minute walk (6-MW) distance, modified Physical Performance Test (mPPT), and Medical Outcomes Study 36-item Short Form Survey (SF-36) physical function. RESULTS: The primary endpoint was 1 year after fracture. Isometric force production (P=.006), usual (P=.02) and fast (P=.03) gait speed, 6-MW distance (P=.005), and mPPT score (P<.001) were improved 1 year after fracture with exercise. Effect sizes were 0.79 for strength, 0.81 for mPPT score, 0.56 for gait speed, 0.49 for 6-MW, and 0.30 for SF-36 score. More patients in the exercise group made meaningful changes in gait speed and 6-MW distance than control patients (chi-square P=.004). CONCLUSION: A 10-week home-based progressive resistance exercise program was sufficient to achieve moderate to large effects on physical performance and quality of life and may offer an alternative intervention mode for patients with hip fracture who are unable to leave home by 6 months after the fracture. The effects were maintained at 3 months after completion of the training program. |
