Magnetic motor evoked potentials in ponies

Abstract

Magnetic stimulation of motor pathways was used to effect motor unit action potential recordings from forelimb and hindlimb muscles in unanesthetized ponies. Motor pathway conduction velocities to the forelimb and hindlimb were determined to be 53.8 ± 9.6 m/s-1 and 63.4 ± 8.3 m/s-1, respeclively. This noninvasive technique will enable more precise evaluation of motor deficits in clinical patients than is possible with the neurological examination.
