摘要

背景:扁平足改变了下肢的排列,也可能改变运动时跟腱的负荷分布。本研究的目的是研究通过抵抗性踝关节跖屈运动对扁平足患者跟腱的累积横向应变的直接影响。方法:选取14名平足患者和14名年龄相匹配的正常足部姿势患者。跟腱厚度采用超声仪测量,超声仪在跟骨上侧面近端1、2和3cm处有线性探头。在参与者完成90次双小腿抬高练习之前和之后进行超声测量,包括将脚从踝关节完全背屈移动到踝关节完全跖屈。结果:与对照组相比,运动前和运动后平足组跟腱三个测点厚度均较薄(P < 0.05)。两组运动后跟腱3点厚度均减小(P < 0.001)。在运动前和运动后测量的所有三个点的跟腱厚度差异中,扁平足患者比对照组低(P < 0.05)。结论:两组运动后跟腱厚度均有明显降低;然而,在正常足部姿势的个体中,肌腱厚度明显减少。这些发现被认为是跟腱结构和跟腱负荷分布变化的结果。

Immediate Effect of Cumulative Transverse Strain via Exercise on the Achilles Tendon in Individuals with and Without Flat Feet.

Background: Flat feet change lower-extremity alignment, and they may change the load distribution on the Achilles tendon during exercise. The purpose of this study was to investigate the immediate effect of cumulative transverse strain via resistive ankle plantarflexion exercise on the Achilles tendon in individuals with flat feet.

Methods: Fourteen individuals with flat feet and 14 age-matched individuals with normal foot posture were enrolled. Achilles tendon thickness was measured by an ultrasonography device with a linear probe at three points: 1, 2, and 3 cm proximal to the superior aspect of the calcaneus. Ultrasonography measurements were performed before and after participants completed 90 repetitions of double-leg calf raise exercises, which included moving the foot from full ankle dorsiflexion to full ankle plantarflexion.

Results: Achilles tendon thickness at all three points measured was thinner in the flat feet group at preexercise and postexercise conditions compared with that of the control group (P < .05). Achilles tendon thickness at all three points decreased after the exercise in both groups (P < .001). The differences in Achilles tendon thickness at all three points measured between preexercise and postexercise conditions were lower in individuals with flat feet than in those of the control group (P < .05).

Conclusions: There was a significant decrease in Achilles tendon thickness after exercise in both groups; however, tendon thickness markedly diminished in individuals with normal foot posture. The findings are thought to result from changes in tendon structure and load distribution on the Achilles tendon.
