本文对27例痉挛型双瘫脑性瘫痪（CP）患儿（年龄3 ~ 18岁，平均9岁）和12例非CP患儿（年龄5 ~ 18岁，平均9岁）的踝关节痉挛和肌力进行了观察。为了测量痉挛，KinCom测力计以五种不同的速度背屈被动踝关节，并记录阻力跖屈扭矩。在每个速度下计算扭矩-角度数据的工作值。使用该数据，线性回归用于测量痉挛。为了测量力量，测力计以10°/s的速度将踝关节从最大背屈旋转到最大跖屈，同时儿童进行最大跖屈同心收缩。反向运动以记录最大背屈。计算跖屈肌和背屈肌的最大扭矩和功。与CP组相比，CP组的跖屈肌痉挛程度明显更高，跖屈肌和背屈肌的力量明显更低。结果提供了客观的信息量化踝关节痉挛和力量与CP儿童。
Ankle spasticity and strength in 27 children with spastic diplegic cerebral palsy (CP) (mean age 9 years, range 3 to 18 years) and a group of 12 children without CP (comparison group) (mean age 9 years, range 5 to 18 years) were observed. To measure spasticity, a KinCom dynamometer dorsiflexed the passive ankle at five different speeds and recorded the resistive plantarflexion torques. Work values for the torque‐angle data were calculated at each speed. Using this data, linear regression was used to measure spasticity. To measure strength, the dynamometer rotated the ankle from maximum dorsiflexion to maximum plantarflexion at a speed of 10°/s while the child performed a maximum plantarflexion concentric contraction. The movement was reversed to record maximum dorsiflexion. Maximum torques and work by the plantarflexors and dorsiflexors were calculated. The group with CP had significantly more spasticity in the plantarflexors and significantly less strength in the plantarflexors and dorsiflexors than the group without CP. Results provide objective information quantifying ankle spasticity and strength in children with CP.
