关节位置感（JPS）是评估本体感觉的一种方法，是复制目标肢体位置的能力。反馈通常用于改善运动性能，但尚未证明它可以改善JPS。本研究的目的是确定是否反馈减少错误与膝关节JPS在三个运动速度。健康的志愿者坐着，臀部和膝盖弯曲。以三种速度（0.5、2和10°/s）被动伸展膝关节。指导受试者通过拇指开关在20°膝关节屈曲目标下停止膝关节运动。在运动之后，每个受试者接收指示相对于目标位置的最终腿部位置的视觉和本体感受反馈。运动速度和时间（4秒，5秒，6秒）是随机呈现的，因此受试者无法预测目标位置。JPS的测量包括恒定误差（CE）、绝对误差（AE）、可变误差（VE）和正确百分比（%CORR）。CE、AE和VE显著降低以及%CORR增加。大多数JPS改善（85%）发生在第十次试验。JPS的短期改善可能是通过提供给受试者的反馈进行暂时CNS适应的结果。JPS增强的长期学习需要进一步研究。
Joint position sense (JPS), one method to assess proprioception, is the ability to replicate a target limb position. Feedback is commonly used to improve motor performance but it has not been demonstrated to improve JPS. The purpose of this study was to determine if feedback decreases error associated with knee JPS at three movement velocities. Healthy volunteers sat with their hip and knees flexed. The knee was passively extended at three velocities (0.5, 2, and 10°/s). Subjects were instructed to stop knee motion, via a thumb switch, at a 20° knee flexion target. Following movement, each subject received visual and proprioceptive feedback indicating final leg position relative to the target position. Movement velocities and times (4 s, 5 s, 6 s) were randomly presented so subjects could not predict the target position. Measures of JPS included constant error (CE), absolute error (AE), variable error (VE), and percent correct (%CORR). Significant decreases in CE, AE, and VE as well as an increase in %CORR were demonstrated. The majority of JPS improvement (85%) occurred by the tenth trial. Short-term improvements in JPS may be the result of temporary CNS adaptations via feedback that was provided to subjects. Long-term learning of JPS enhancement needs further investigation.
