Repetitive nerve stimulation of facial muscles in MuSK antibody-positive myasthenia gravis.

abstract：INTRODUCTION:Far-field potentials (FFPs) from muscles other than the abductor digiti minimi (ADM) may interfere with motor unit number estimation (MUNE) from that muscle. METHODS:We identified the origin of each surface motor unit potential (SMUP) during hypothenar MUNE using the multiple point stimulation method in 2...
