title: [The influence of afferent inputs from the foot load receptors onto spinal alpha-motoneurons excitability in air-stepping condition].
abstract: We investigated excitability of alpha-motoneurons during voluntary and passive locomotor-like movements under air-stepping conditions during the imitation of foot loading. Limb loading notably inhibited the H-reflex during both static condition and active or passive stepping. Thus, load-related afferent inputs play an essentially role in phase-dependence H-reflex modulation. The excitability of alpha-motoneurons in the most degree is influenced by afferent inflow from foot receptors.
