该研究的目的是评估实时听觉反馈对膝关节本体感觉的影响。 30 名健康参与者被随机分配到对照组 (n = 15) 和实验组 I (15)。参与者使用他们的优势腿执行主动膝盖重新定位任务，有/没有额外的实时听觉反馈，其中频率以收敛的方式映射到两个不同的目标角度（40 和 75°）。统计分析显示，在组内和组间，实时听觉反馈的恒定和绝对误差的膝关节重新定位准确性显着提高。除了这个收敛条件之外，我们还建立了第二个发散条件。在这里，进行了频率的逐步变换，以探索听觉本体感受重新定位之间是否存在系统调整。在这种不同的听觉反馈条件下没有发现显着的影响。还包括一个额外的实验组 II (n = 20)。在这里，我们研究了频率逐步换位的较大幅度和方向变化的影响。第一步，结果证实了实验一的结果。此外，当应用不同的听觉反馈时，对膝关节听觉本体感觉重新定位的显着影响是显而易见的。在逐步换位过程中，参与者表现出在换位相反方向上系统地调节膝盖运动。我们确认，通过同时应用实时听觉反馈可以提高膝盖重新定位的准确性，并且可以通过逐步变换频率以目标导向的方式调节膝盖重新定位。讨论了康复环境中关节位置感的临床意义。
The purpose of the study was to assess the influence of real-time auditory feedback on knee proprioception. Thirty healthy participants were randomly allocated to control (n = 15), and experimental group I (15). The participants performed an active knee-repositioning task using their dominant leg, with/without additional real-time auditory feedback where the frequency was mapped in a convergent manner to two different target angles (40 and 75°). Statistical analysis revealed significant enhancement in knee re-positioning accuracy for the constant and absolute error with real-time auditory feedback, within and across the groups. Besides this convergent condition, we established a second divergent condition. Here, a step-wise transposition of frequency was performed to explore whether a systematic tuning between auditory-proprioceptive repositioning exists. No significant effects were identified in this divergent auditory feedback condition. An additional experimental group II (n = 20) was further included. Here, we investigated the influence of a larger magnitude and directional change of step-wise transposition of the frequency. In a first step, results confirm the findings of experiment I. Moreover, significant effects on knee auditory-proprioception repositioning were evident when divergent auditory feedback was applied. During the step-wise transposition participants showed systematic modulation of knee movements in the opposite direction of transposition. We confirm that knee re-positioning accuracy can be enhanced with concurrent application of real-time auditory feedback and that knee re-positioning can modulated in a goal-directed manner with step-wise transposition of frequency. Clinical implications are discussed with respect to joint position sense in rehabilitation settings.
