Significant movement-induced gain changes in H reflexes have 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.
在下肢被动运动后,比目鱼肌中观察到明显的运动诱发的H反射增益变化。基于这些概念的假设在紧张收缩的胫骨前肌的H反射幅度上进行了测试。对11名受试者以每分钟20次和60次的速度进行被动腿部运动,与对照组相比出现了统计学上显著的衰减和相位调制。这些结果使比目鱼肌H反射的结论更具普遍性。然而,由于胫骨前肌的H反射比目鱼肌中的小,其功能效应应该小得多。
