A STUDY OF EVOKED ELECTROMYOGRAPHY OF THE INFERIOR ORBICULARIS ORIS MUSCLE IN MAN

The facial nerves on one side in normal persons were stimulated by bipolar concentric needle electrode, and the evoked potentials were picked up to determine the conduction speed, extent and recorded potentials of the inferior orbicularis oris muscle. Evoked potentials were recorded up to 1.5 to 2.5 cm across the midline of the lower lip. The conduction speed reduced abruptly and the amplitude became small.
