Abstract

Clinical evaluation of clonus in spastic muscles was performed by comparing reflex path length with clonus frequency for different muscles in the same patient. It was found that clonus frequency varied inversely with reflex path length (r = 0.84, p less than 0.001). The findings confirm that clonus is generated by a peripheral mechanism of self re-excitation rather than a central spinal pacemaker.

摘要

通过比较同一患者不同肌肉的反射路径长度与阵挛频率，对痉挛肌肉中的阵挛进行了临床评估。结果发现，阵挛频率与反射路径长度呈反比（r = 0.84，p < 0.001）。这些发现证实，阵挛是由外周自我再兴奋机制产生的，而非中枢脊髓起搏器。
