Objective The aim of the study was to examine the differences in joint position sense at the elbow joint between 15 children with unilateral cerebral palsy (CP) and 15 typically developing (TD) controls without neurological or other health deficits. Methodology Joint position sense, a major proprioceptive component, was evaluated actively using a Kin Com 125 AP isokinetic dynamometer (Chattanooga Group, Chattanooga, TN). Results A significant interaction was found (p<0.05) between disability and side, with respect to the active reproduction movement scores. Post-hoc independent t-tests, with Bonferroni adjustments, revealed significant differences for the dominant (t=-3.63, p=0.001) and non-dominant sides respectively (t=-6.19, p=0.000). Repeated measures t-test revealed wider errors with the non-dominant (affected side) in the active reproduction test, compared to the dominant (nonaffected) side for the CP group of children (t=-4.73, p=0.000). A positive correlation was evident between the level of spasticity and joint position sense (Rho=0.71, p=0.003). Conclusions Based on our findings, joint position sense is impaired at the elbow joint in children with spastic hemiplegia. The proprioceptive deficit is present at both the affected and unaffected sides and is related to the level of spasticity.
目的 本研究旨在探讨15名单侧脑瘫（CP）儿童与15名无神经或其他健康缺陷的正常发育（TD）对照儿童在肘关节处的关节位置觉差异。方法 使用Kin Com 125 AP等速测力计（查塔努加集团，田纳西州查塔努加）对主要本体感觉成分关节位置觉进行主动评估。结果 在主动再现运动评分方面，发现残疾与侧别之间存在显著交互作用（p<0.05）。经Bonferroni校正的事后独立t检验显示，优势侧（t=-3.63，p=0.001）和非优势侧分别存在显著差异（t=-6.19，p=0.000）。重复测量t检验显示，与CP组儿童的优势侧（未受影响侧）相比，非优势侧（患侧）在主动再现测试中的误差更大（t=-4.73，p=0.000）。痉挛程度与关节位置觉之间存在显著正相关（Rho=0.71，p=0.003）。结论 根据我们的研究结果，痉挛性偏瘫儿童的肘关节处关节位置觉受损。本体感觉缺陷在患侧和未患侧均存在，且与痉挛程度有关。
