Subjects with cerebral palsy aged six to 19 years undertook a training programme to reduce spasticity and contracture of the triceps surae muscle using feedback of the gain of the tonic stretch reflex. Stretch reflex gain was significantly reduced (by 50 per cent on average) in all eight test subjects, whereas there was no significant change in control subjects, matched for age and level of spasticity, who had no reflex training. Contracture of the triceps surae muscle was not altered. Since the reduction in spasticity can be expected to slow the recurrence of muscle shortening, it is suggested that for correction of muscle contracture, muscle-lengthening procedures to promote muscle growth should be combined with reflex training to maintain the growth achieved.
6至19岁的脑瘫患者参加了一项训练计划，该计划利用紧张性牵张反射增益的反馈来减轻小腿三头肌的痉挛和挛缩。在所有8名受试对象中，牵张反射增益显著降低（平均降低50%），而在年龄和痉挛程度匹配但未接受反射训练的对照对象中，没有显著变化。小腿三头肌的挛缩没有改变。由于痉挛的减轻有望减缓肌肉缩短的复发，因此建议为矫正肌肉挛缩，促进肌肉生长的肌肉延长手术应与反射训练相结合，以维持所取得的生长效果。
