目的:姿势稳定性与其三个潜在贡献者的静态和动态相关性,即,本体感受,触感,慢性踝关节不稳定(CAI)患者的力量仍不清楚。本研究旨在比较静态和动态姿势稳定性,随着本体感受,触感,以及有和没有CAI的人之间的力量,并探索他们的相关性。
方法:本研究纳入了67名有CAI的参与者和67名无CAI的参与者。脚踝本体感觉,足底触感,和下肢力量通过本体感觉测试装置测量,一组单丝,和一个强度测试系统,分别。在力板上站立和跳跃着陆期间测量静态和动态姿势稳定性,并以压力中心和稳定时间的均方根表示。
结果:与没有CAI的人相比,有CAI的人姿势稳定性较差,本体感受,触感,和力量。两组都证明了本体感觉和静态姿势稳定性之间的相关性,但只有没有CAI的人表现出本体感觉和动态姿势稳定性之间的相关性。两组都证明了触觉和静态姿势稳定性之间的相关性,但不具有动态稳定性。两组都证明了力量与静态和动态姿势稳定性之间的相关性。
结论:患有CAI的人在静态和动态姿势稳定性方面存在缺陷,本体感受,触感,和力量。在有CAI的人中,本体感受,触感,和力量可以帮助保持静态姿势稳定性;力量可以帮助保持动态姿势稳定性,而本体感觉可能无法为动态姿势稳定性提供足够的信息。
OBJECTIVE: The static and dynamic correlations of postural stability to its three potential contributors, namely, proprioception, tactile sensation, and strength remain unclear among people with chronic ankle instability (CAI). This study aimed to compare static and dynamic postural stability, along with proprioception, tactile sensation, and strength between people with and without CAI and explore their correlations.
METHODS: Sixty-seven participants with CAI and 67 participants without CAI were enrolled in this study. Ankle proprioception, plantar tactile sensation, and lower limb strength were measured by a proprioception test device, a set of monofilaments, and a strength testing system, respectively. Static and dynamic postural stability were measured during standing and jump landing on a force plate and indicated by the root mean square of center of pressure and time to stability.
RESULTS: Compared to people without CAI, people with CAI had poorer postural stability, proprioception, tactile sensation, and strength. Both groups demonstrated correlation between proprioception and static postural stability, but only people without CAI showed correlation between proprioception and dynamic postural stability. Both groups demonstrated a correlation between tactile sensation and static postural stability, but not with dynamic stability. Both groups demonstrated a correlation between strength and both static and dynamic postural stability.
CONCLUSIONS: People with CAI had deficits in static and dynamic postural stability, proprioception, tactile sensation, and strength. Among people with CAI, proprioception, tactile sensation, and strength can help maintain static postural stability; strength can help maintain dynamic postural stability, whereas proprioception may not provide sufficient information for dynamic postural stability.
