研究设计：对照实验室研究采用横断面设计。结论：描述胫骨后腱功能障碍（PTTD）女性的踝关节和髋关节肌肉表现，并将其与匹配的对照组进行比较。我们假设患有PTTD的女性的脚踝跖屈肌力量、髋伸肌和外展肌力量和耐力会减弱，并且这种损害可能是功能障碍方面的。背景：具有博士学位的人表现出行走能力受损。步行步态是强烈依赖于小腿和臀部肌肉组织的性能。方法：34名中年妇女（17 PTTD）参加。踝关节跖屈肌强度采用单腿足跟抬高试验进行评估。髋关节肌肉的性能，包括力量和耐力，测力。组和双方之间的差异进行了评估与混合模型的方差analysis of variances.Results：女性PTTD进行显着减少单腿脚跟提高和重复矢状面和额状面非承重腿升降机，也有较低的髋关节伸肌和外展肌扭矩比年龄匹配的控制。两组的髋关节力量和耐力的措施，双方之间没有差异，但双方之间的差异，在踝关节力量的措施，注意到在两个group.CONCLUSION：妇女PTTD表现出减少踝关节和髋关节肌肉的性能双边。J Orthop Sports PhysTher 2011;41（9）：687-694。doi：10.2519/jospt.2011.3427
STUDY DESIGN: Controlled laboratory study using a cross-sectional design.OBJECTIVES: To characterize ankle and hip muscle performance in women with posterior tibial tendon dysfunction (PTTD) and compare them to matched controls. We hypothesized that ankle plantar flexor strength, and hip extensor and abductor strength and endurance, would be diminished in women with PTTD and this impairment would be on the side of dysfunction.BACKGROUND: Individuals with PhD demonstrate impaired walking abilities. Walking gait is strongly dependent on the performance of calf and hip musculature.METHODS: Thirty-four middle-aged women (17 with PTTD) participated. Ankle plantar flexor strength was assessed with the single-leg heel raise test. Hip muscle performance, including strength and endurance, were dynamometrically measured. Differences between groups and sides were assessed with a mixed-model analysis of variance.RESULTS: Females with PTTD performed significantly fewer single-leg heel raises and repeated sagittal and frontal plane non-weight-bearing leg lifts, and also had lower hip extensor and abductor torques than age-matched controls. There were no differences between sides for hip strength and endurance measures for either group, but differences between sides in ankle strength measures were noted in both groups.CONCLUSION: Women with PTTD demonstrated decreased ankle and hip muscle performance bilaterally.
