Slow soleus muscle in guinea pigs was actively shortened by constant electrical stimulation of the sciatic nerve for 12 hours. At the end of this period, hypoextensibility and a 25% decrease in the numbers of sarcomeres were observed. When a 36- or 48-hour period was allowed to elapse after the end of stimulation, some recovery occurred, and the sarcomere numbers were then found to be diminished by only 5%. If the stimulation was performed when the muscle was prevented from shortening (by ankle fixation in dorsiflexion), there was no decrease in sarcomere numbers and no hypoextensibility after neuroaxis lesions, when abnormal contractions maintain lasting shortening of the muscle.
通过持续电刺激豚鼠的坐骨神经12小时，使比目鱼慢肌主动缩短。在此期间结束时，观察到肌肉伸展性降低，肌节数量减少25%。在刺激结束后经过36或48小时，肌肉出现了一些恢复，此时发现肌节数量仅减少5%。如果在肌肉被阻止缩短时（通过背屈位固定踝关节）进行刺激，在神经轴损伤后，当异常收缩使肌肉持续缩短时，肌节数量没有减少，也没有出现伸展性降低的情况。
