Journal of Neurophysiology, 78, , Effect of Body Weight Supported Walking on H-reflex of Soleus Muscle and Electromyogram of Lower Extremity Hiroshi OSAKA, Kenichi KOBARA, Daisuke FUJITA, Hiroshi ISHIDA, Yosuke YOSHIMURA andsusumu WATANABE (AcceptedNov. 16, 2009) Key words : H-reflex, body weight support, electromyogram Abstract Eight healthy subjects walked on a treadmill (TW) unaided and then walkedon a treadmill with 20% of their body weight supported(bwstw). The maximum amplitude ratio of H-wave to M-wave of the soleus muscleh/m ratiowas measuredbefore andafter both TW andbwstw. Furthermore, surface electromyogram of the tibialis anterior andsoleus muscle was measuredandcalculated%iemg during TW andbwstw; the results were compared. The H/M ratio showeda significant decrease before andafter both TW andbwstw. The change rate before andafter walking was not significant between TW andbwstw. In BWSTW, %IEMG of the tibialis anterior showeda significant decrease during the initial contact phase comparedwith that in TW. %IEMG of the soleus muscle showeda significant decrease during the terminal stance phase. The decrease in the ratio of soleus muscle H/M before andafter BWSTW was similar to that in TW. Because the effect of reciprocal inhibition to the soleus muscle was demonstrated in both BWSTW and TW, this indicates that BWSTW might be as effective in TW patients who have the spasticity inthe triceps surae.
