摘要：

Significant movement-induced gain changes in H reflexes hare been observed in soleus muscle following passive movement of the lower limb. Hypotheses from these concepts were tested on magnitudes of H reflexes in tonically contracted tibialis anterior. From eleven subjects at rates of 20 and 60 r.p.m, passive leg movement, statistically significant attenuation from controls and phasic modulation occurred. The results make more general the conclusions from soleus H reflexes. However, the functional effect should be much smaller,as tibialis anterior H reflexes are smaller compared to those in soleus.
