Abstract

The H-reflex was studied in 53 children with cerebral palsy, and the results were compared with those obtained for 56 normal control subjects. Pairs of identical stimuli were delivered and the time course of recovery of the amplitude of the H-reflex was determined. Recovery of the H-reflex was increased in the normal control group aged 0 to 12 mos compared to that in the normal control group aged 1 to 9 yrs, especially at interstimulus intervals from 100 to 800 msec. In children with spasticity, marked recoveries of the H-reflex were observed in both age groups, 0 to 12 mos and 1 to 9 yrs, compared to those in normal controls. In the cases of athetosis, recovery of the H-reflex was also marked. In children with ataxia, it was not pronounced and similar to that in normal controls. From these findings, an H-reflex study was considered to be useful for evaluation of central nervous system function in childhood.
