Abstract

Purpose
The purpose of this pilot study is to identify the problems and stability of a study to investigate “Effects of Squat Exercise according to Weight Support on Balance and Gait in Patients after Total Hip Replacement.” before proceeding with the study.
Methods
Twenty-two rehabilitation patients after THR surgery who met the selection criteria participated. The study subjects were randomly assigned to a squat group using a slider or a squat group using a reformer. The interventions were applied for two weeks. The patients were assessed using Berg balance scale (BBS), Timed up and go test (TUG), and 10-meter walking test (10MW).
Results
Although twenty-two study subjects participated in this study, eight study subjects participated dropouts occurred during the study period. There was a significant difference within the group in BBS and TUG in two groups (p < 0.05). The difference between the two groups was not significant in all outcome measures (p > 0.05). The largest effect size was 1.21 and the smallest effect size was 0.39, all from the BBS.
Conclusion
This pilot study suggest that it is feasible with minor adjustment to conduct a larger scale, powered RCT to examine the efficacy of squat exercise according to weight support with patients after THR.
