In order to formulate a hypothesis regarding the etiology of toe walking, the sensory processing abilities of 17 mentally retarded children who toe walk were examined. A galvanic skin response was used to compare reactions of the mentally retarded children and a group of normal children to a variety of sensory stimuli. Galvanic skin response testing did not reveal significant differences between the two groups in processing sensory input. Scores of the mentally retarded children from a postrotary nystagmus test were compared to values for normal children of the same age, and the results indicated that vestibular dysfunction was present in all of the subjects. We hypothesize that children may toe walk to increase somatosensory input to the lateral vestibular nucleus (Deiter's) and the lateral vestibulospinal tract to facilitate support tone in the lower extremities during walking.
为了就足尖行走的病因提出一个假设,对17名足尖行走的智障儿童的感觉加工能力进行了检查。采用皮肤电反应来比较智障儿童和一组正常儿童对各种感觉刺激的反应。皮肤电反应测试未显示两组在处理感觉输入方面存在显著差异。将旋转后眼震试验中智障儿童的得分与同龄正常儿童的值进行比较,结果表明所有受试者均存在前庭功能障碍。我们假设,儿童可能会足尖行走,以增加向外侧前庭核(代特氏核)和外侧前庭脊髓束的体感输入,从而在行走时促进下肢的支撑肌张力。
