Electrophysiological characterization of central sensory and motor pathway function in patients with moderate...

The central sensory and motor pathway function in patients with moderate hemiparesis and in healthy persons was selectively characterized by evaluation of latencies of short (R1) and long (R2) latency EMG responses as well as simultaneously recorded sensorimotor potentials (N19, N26) evoked by electrical stimulation of median and peroneal nerve (additionally, calculation of peripheral and central sensory/motor conduction times). This investigation procedure permits a noninvasive quantification of disturbed central sensory and motor pathway function in hemiparetic patients. The results found are in agreement to clinical, CT and other examination findings.
