WebF-wave study. F-wave study uses supramaximal stimulation of a motor nerve and recording of action potentials from a muscle supplied by the nerve. This is not a reflex, per se, in that the action potential travels from the site of the stimulating electrode in the limb to the spinal cord's ventral horn and back to the limb in the same nerve that was stimulated. Web20 de ago. de 2024 · Late responses include F waves and H reflexes. F waves The F wave is a late response involving the motor axons that can be elicited in most upper and lower extremity muscles.
