Abstract

Purpose: The purpose of this study was to measure changes in the H-reflex and V wave under loading conditions (e.g. prone and standing position) and to investigate whether postural change would affect the H-reflex and V wave in post stroke hemiplegic patients.
Methods: Thirty persons with hemiplegia resulting from stroke (20 males, 10 females) participated in this study. Electromyography (EMG) was used to electrically stimulate and record the soleus H-reflexes and V waves under various loading conditions. The normality of the distribution of each variable (H latency, ratio, ratio) was tested using the Kolmogorov-Smirnov test. The means of normally distributed continuous data were assessed by independent t-test (=0.05).
Results: There were statistically significant differences in ratio (p<0.01), ratio (p<0.01), H latency (p<0.01) among the prone and standing position.
Conclusion: We found that the H-reflex and V wave in standing position was more active to weight bearing load than prone position.
