Ankle extensor proprioceptors contribute to the enhancement of the soleus EMG during the stance phase of human walking



Ankle extensor proprioceptors contribute to the enhancement of the soleus EMG during the stance phase of human walking



Canadian Journal of Physiology and Pharmacology 82(8-9): 610-616



A rapid plantar flexion perturbation applied to the ankle during the stance phase of the step cycle during human walking unloads the ankle extensors and produces a marked decline in the soleus EMG. This demonstrates that sensory activity contributes importantly to the enhancement of the ankle extensor muscle activation during human walking. On average, the EMG begins to decline approximately 52 ms after the perturbation.
