摘要: Abstract The pattern and timing of motor output during human locomotion are probably determined by a mixture influences, some arising from neural circuits entirely within the central nervous system others variety sensory receptors. Muscle reflexes highly modulated in an adaptive manner each phase step cycle. Furthermore, modulation can be incorporated quickly for different tasks such as standing, walking running, most likely changes presynaptic inhibition. Inhibitory also with level activity muscle being inhibited, but strength these does not seem to switched task-dependent manner. Cutaneous completely reversed excitatory inhibitory cycle, particularly muscles that normally show two bursts per These reflex modulations appear important safely maintaining forward progression over varying terrain.
