To investigate differences in proprioception using four proprioceptive tests in children with and without hypermobility. Additionally, it was tested if the results on one proprioceptive test predict the results on the other tests. Of the children (8-11years), 100 were classified as normal mobile (Beighton score 0-4) and 50 as hypermobile (Beighton score 5-9). To test proprioception, in the upper extremity the unilateral and bilateral joint position reproduction tasks were used and for the lower extremity the loaded and unloaded wedges task. No differences were found in any of the proprioception tests between the two groups. Estimating the height of the wedges was easier in the loaded position (mean penalty in standing and sitting position, 4.78 and 6.19, respectively). Recalling the elbow position in the same arm resulted in smaller errors compared to tasks reproducing the position with the contralateral arm. Of the four angles used (110°, 90°, 70°, 50°), the position recall in the 90° angle had the smallest position error (1.8°). Correlations between the proprioception tests were weak (Loaded and Unloaded (r 0. 28); Uni and Bilateral (r 0.39), Upper and Lower extremity not significant). No indication of poorer proprioception was found in children with hypermobile joints compared to their normal mobile peers. Loading gives extra information that leads to fewer errors in the wedges task performed while standing, but this effect is independent of joint mobility. Proprioception test outcomes are dependent on the test used; upper extremity results do not predict lower extremity outcomes or vice versa.
研究了四种本体感受测试在患有和不患有过度活动症的儿童中的本体感受差异。此外，还测试了一项本体感受测试的结果是否可以预测其他测试的结果。在（8-11 岁）儿童中，100 名被归类为正常活动（Beighton 评分为 0-4），50 名被归类为过度活动（Beighton 评分为 5-9）。为了测试本体感受，在上肢使用了单侧和双侧关节位置再现任务，在下肢使用了负载和空载楔形任务。在两组之间，在任何本体感受测试中都没有发现差异。在负载位置估计楔子的高度更容易（站立和坐姿的平均罚分分别为 4.78 和 6.19）。与使用对侧手臂再现位置的任务相比，回忆同一手臂的肘部位置会导致较小的误差。在所使用的四个角度（110°、90°、70°、50°）中，90°角的位置回忆具有最小的位置误差（1.8°）。本体感受测试之间的相关性较弱（负载和空载（r 0.28）；单侧和双侧（r 0.39），上肢和下肢无显著差异）。与正常活动的同龄人相比，患有过度活动关节的儿童并未表现出较差的本体感受。负载会提供额外的信息，从而减少站立时执行的楔形任务中的错误，但这种效果与关节活动度无关。本体感受测试结果取决于所使用的测试；上肢结果不能预测下肢结果，反之亦然。
