H-reflex modulation during reverse passive pedalling

During passive pedalling or walking movements of the human leg, the gain of the soleus H reflex is depressed in proportion to the rate of the movement, with the depression maximal at the end of leg flexion. In this phase, maximum flexion of the hip and knee occur at different positions. The question was raised as to whether the gain changes still occur when the direction of movement is reversed, thus reversing those positions. In four subjects, …
