进行实验以确定在非残疾儿童和脑瘫儿童组中是否存在相互抑制的脊髓和脊髓上成分（一种负责防止随意运动期间肌肉协调的神经机制）。在踝关节自主背屈和跖屈期间以及在胫骨前肌腱施加振动期间检查腓肠肌-比目鱼肌H反射的变化。结果表明，脑性瘫痪儿童在随意运动前和随意运动中均存在相互抑制功能障碍。这些缺陷涉及到棘上中枢的损伤，导致他们无法进行平稳、协调的运动。
Experiments were performed to determine whether spinal and supraspinal components of reciprocal inhibition (a neural mechanism responsible for the prevention of muscular co‐ordination during voluntary movement) were present in groups of non‐disabled children and children with cerebral palsy. Changes in the gastrocnemius‐soleus H reflex were examined during voluntary dorsiflexion and plantarflexion of the ankle and during a vibration applied to the anterior tibial tendon. The results indicate that children with cerebral palsy have impairments in reciprocal inhibition, both before and during voluntary movement. These deficits, which involve damage to supraspinal centres, contribute to their inability to perform smooth, co‐ordinated movements.
