49 patients who had undergone total hip arthroplasty were randomized to either a 6-week home-based progressive resistance training (PRT) regimen or standard inpatient/outpatient physiotherapy without PRT exercises. The purpose of this study was to evaluate if the home-base PRT group demonstrated significantly better results regarding isokinetic quadriceps strength and functional performance measures compared to standard rehabilitation over 9-12 months follow-up. Results demonstrated no significant differences between groups in the change from baseline to 9-12 months postoperatively in either maximal isokinetic quadriceps strength, the sit-to-stand test, or the timed up-and-go test. Results also demonstrated significantly greater improvement in stair climb performance and the 6-minute walk test in the standard rehabilitation group compared to the home-based PRT group.
