Soleus H-reflex phase-dependent modulation during one-legged foot reaching and withdrawal in standing humans

▶ The soleus H-reflex is modulated in a phase-dependent pattern during one-legged foot reaching in standing humans. ▶ Presynaptic inhibition is increased during the withdrawal phase of the motor task. ▶ Presynaptic inhibition is decreased during the approach phase of the motor task.
