Objective: This study is designed to examine the difference in flexor carpi radialis (FCR) H-reflex between hemiplegic patients and normal subjects, and to investigate the relation-ship between parameters of FCR H-reflex and upper limb spasticity. Methods: H-reflex of FCR was performed to 47 normal person and 20 hemiplegic patients. Parameters used were onset latency, amplitude and Hmax/Mmax ratio. Effect by factors like age, sex, arm length and relationship between Modified Ashworth scale (MAS) and parameters of H-reflex in spasticity of hemiplegic patients was analyzed by SPSS 10.0 Result: In normal subjects, amplitude correlated inversely with age (p<0.01), arm length correlated directly with onset latency (p<0.01). Amplitude and Hmax/Mmax ratio were increased significantly in hemiplegic patients than normal person (p<0.01), correlated directly with MAS at the wrist (p<0.01) . Conclusion: FCR H-reflex in normal subjects was influenced by arm length and age. Amplitude and Hmax/Mmax ratio among parameters were significantly different in both groups and was significantly correlated with upper limb spasticity. From these findings, FCR H-reflex is considered to be useful adjunctive study for evaluation of upper limb spasticity in hemiplegic patients.
