Patients with spinal cord injury or multiple sclerosis were surveyed for the presence of extreme foot deformities and spasticity. Pes cavus and claw toes were found in eight of 80 spastic spinal cord injury and two of 20 multiple sclerosis patients. Pes cavus and claw toes were not found in 29 flaccid spinal cord injury patients. Pes cavus and claw toes were associated with flexor reflexes which could be elicited by pin prick proximal to the knee, suggesting extreme spasticity--and by low excitatory thresholds for the anterior tibialis as indicated electromyographically. Complications of severe spasticity associated with spinal cord injury and multiple sclerosis include pes cavus and claw toes, mediated in part by spasms of the anterior tibialis.
对脊髓损伤或多发性硬化症患者进行了调查，以确定是否存在严重的足部畸形和痉挛。在80例痉挛性脊髓损伤患者中有8例、20例多发性硬化症患者中有2例出现高弓足和爪形趾。29例弛缓性脊髓损伤患者未出现高弓足和爪形趾。高弓足和爪形趾与屈肌反射有关，在膝盖近端进行针刺可诱发屈肌反射，提示存在严重痉挛，并且肌电图显示胫前肌的兴奋性阈值较低。与脊髓损伤和多发性硬化症相关的严重痉挛的并发症包括高弓足和爪形趾，部分由胫前肌痉挛介导。
