The purpose of this study was to determine the acute effect of hamstring foam rolling on proprioception at the knee and hip joints. Twenty-five participants completed two proprioceptive tests on separate days, in a random order. The joint position matching test used no visual feedback. Participants were verbally guided to a target lunge position, which was maintained for six seconds while right hip and knee angles were recorded. After rest, participants reproduced this position without guidance for six seconds. Three trials were completed at baseline, and zero, 10, and 20 minutes post-intervention. In the force matching test, participants completed three trials with feedback about force output from a graph, and three trials without. They gradually applied knee flexion force against the dynamometer until reaching target force output. This test was also completed at baseline, and zero, 10, and 20 minutes post-intervention. A significant main effect was found for absolute knee position matching error (F(1.97, 47.36), p = 0.004). No significant differences were found between post-intervention values at zero and 10 minutes, zero and 20 minutes, or 10 and 20 minutes for absolute hip position matching error or absolute knee force matching error at zero, 10, or 20 minutes (p > 0.05). Foam rolling improved knee joint position sense for at least 20 minutes post-intervention, and did not decrease hip joint position sense or knee joint force sense. This indicates that foam rolling may be used immediately prior to exercise without the risk of injury due to proprioceptive deficits.
本研究的目的是确定腘绳肌泡沫轴放松对膝关节和髋关节本体感觉的急性影响。25名参与者在不同日期以随机顺序完成了两项本体感觉测试。关节位置匹配测试不使用视觉反馈。参与者通过言语引导至目标弓步姿势，保持6秒，同时记录右髋和膝关节角度。休息后，参与者在无引导的情况下重现该姿势6秒。在基线、干预后0分钟、10分钟和20分钟时各完成3次试验。在力量匹配测试中，参与者完成3次有来自图表的力量输出反馈的试验，以及3次无反馈的试验。他们逐渐对测力计施加屈膝力，直到达到目标力量输出。该测试同样在基线、干预后0分钟、10分钟和20分钟时完成。发现绝对膝关节位置匹配误差存在显著的主效应（F(1.97, 47.36)，p = 0.004）。在干预后0分钟、10分钟或20分钟时，绝对髋关节位置匹配误差或绝对膝关节力量匹配误差在0分钟与10分钟、0分钟与20分钟或10分钟与20分钟之间的干预后值无显著差异（p > 0.05）。泡沫轴放松在干预后至少20分钟内改善了膝关节位置觉，且未降低髋关节位置觉或膝关节力量觉。这表明在运动前可立即使用泡沫轴放松，而不存在因本体感觉缺陷导致受伤的风险。
