Abstract
|
|
|
Purpose: The purpose of this study was to investigate the immediate effects of hip flexor stretching with pelvic fixationon the flexibility of hip extension and gait capacity in subjects with limited hip extension flexibility.
Methods: Twenty-six subjects with limited hip extension flexibility were divided into two groups: a hip flexor stretchingwith pelvic fixation group (n = 13) and a hip flexor stretching without pelvic fixation group (n = 13). The subjectswere assessed based on flexibility of hip extension, stride, and gait velocity after applying hip flexor stretching.
Results: The hip flexor stretching with pelvic fixation group showed significantly improved flexibility of hip extension,stride, and gait velocity compared with hip flexor stretching without pelvic fixation group (p <0.05). The flexibilityof hip extension was significantly improved after application of hip flexor stretching in both groups; however, strideand gait velocity were significantly improved only in the hip flexor stretching with pelvic fixation group.
Conclusion: Hip flexor stretching with pelvic fixation is an effective intervention for improving the flexibility of hipextension and gait capacity.
