The proprioceptive sense is a very important function for the body, and joint position error test (JPET) is commonly used to measure it. This study was to analyze the difference of proprioception in standing and sitting postures through the JPET. A total of 60 students (M/F, 12/48) in D University in Gyeongsangbuk-do, South Korea participated in this study. A JPET was performed with the subject’s eyes closed to assess the neck proprioception. The movement of the neck was measured in flexion, extension, and lateral flexion, and separately measured when sitting and standing. The difference in repositioning errors between sitting and standing postures was analyzed using paired t-test. There was a significant difference in repositioning errors between sitting and standing posture in neck extension. There was no significant difference in repositioning errors between sitting and standing posture in neck flexion and lateral flexion. In conclusion, in a sitting posture, posterior neck muscles are used more than in the standing posture, which may negatively affect the proprioceptive accuracy of the neck and may also increase the neck repositioning errors.

用关节位置误差试验分析站姿和坐姿差异对颈部本体的影响

本体感觉是身体非常重要的功能，常用关节位置误差测试（JPET）来测量。本研究旨在通过JPET分析站立和坐姿本体感觉的差异。韩国庆尚北道 D 大学共有 60 名学生 (M/F, 12/48) 参加了这项研究。在受试者闭眼的情况下进行 JPET 以评估颈部本体感觉。颈部的运动在屈曲、伸展和侧屈时测量，并在坐姿和站立时分别测量。使用配对分析坐姿和站立姿势之间重新定位误差的差异吨-测试。在颈部伸展时，坐姿和站姿的重新定位误差存在显着差异。在颈屈和侧屈时，坐姿和站立姿势的重新定位误差没有显着差异。总之，在坐姿中，颈部后侧肌肉的使用比在站立姿势中更多，这可能会对颈部的本体感觉准确性产生负面影响，也可能会增加颈部重新定位的错误。
