WebThe minimal F wave latency is typically 25-32 ms in the upper extremities, and 45-56 ms in the lower extremities. F wave persistence is the number of F waves obtained per the number of stimulations, which is normally 80-100% (or above 50%). Each skeletal muscle is usually supplied by two or more nerve roots and if one nerve root is affected and ...

WebF wave is a late response that follows the motor response (M) and is elicited by supramaximal electrical stimulation of a mixed or a motor nerve 4. F waves provide a means of examining transmission between stimulation sites in the arm and the leg and the related motor neurons in the cervical and lumbosacral cord. gold wrap car
