Abstract：
BACKGROUND: In children with motor disabilities, knee position during walking is often of concern in rehabilitation. This study aimed to investigate knee joint position sense. Thirty-seven children with Cerebral Palsy (CP), 21 with Myelomeningocele (MMC), 19 with Arthrogryposis (AMC), and 42 TD children participated in the study. Knee joint position sense, i.e., the difference between the criterion angle and the reproduced angle (JPS-error), was assessed in sitting while 3D motion capture was recorded at flexed knee 70 (Knee70), 45 (Knee45), and 20 (Knee20) degrees, and after three seconds at maintained criterion angle (CAM) and maintained reproduced angle (RAM). No differences were found between the groups in JPS-error, CAM, and RAM. At Knee70, CAM differed between the right and left legs in the TD group (p = 0.014) and RAM in the MMC group (p = 0.021). In the CP group, CAM was greater than RAM at Knee70 in the left leg (p = 0.002), at Knee45 in both legs (p = 0.004, p = 0.025), and at Knee20 in the right leg (p = 0.038). Difficulties in maintaining the knee position at CAM in the CP group sheds light on the need for complementary judgments of limb proprioception in space to explore the potential influence on knee position during walking.
摘要：
背景：在有运动障碍的儿童中，行走过程中的膝关节位置通常是康复治疗中需要关注的问题。本研究旨在探讨膝关节位置感。37名脑瘫（CP）儿童，21伴有脊髓膜膨出（MMC），19带有节肢动物（AMC），42名TD儿童参与了这项研究。膝关节位置感,即，标准角度和再现角度之间的差异(JPS误差)，在坐着时进行评估，同时在弯曲的膝盖70（Knee70）处记录3D运动捕捉，45（Knee45），和20（Kne20）度，并且在保持标准角度(CAM)和保持再现角度(RAM)的三秒之后。在JPS错误中，两组之间没有发现差异，CAM,和RAM。在Knee70时，TD组（p=0.014）和MMC组（p=0.021）的右腿和左腿之间的CAM不同。在CP组中，左腿Knee70处的CAM大于RAM（p=0.002），在双腿Knee45处（p=0.004，p=0.025），右腿Knee20（p=0.038）。CP组中在CAM处保持膝盖位置的困难表明，需要对空间中的肢体本体感觉进行补充判断，以探索步行过程中对膝盖位置的潜在影响。
