title: The influence of stimulating techniques on the masseteric and temporal M-responses in man.
abstract: The direct motor responses obtained in the masseter and temporalis muscles after electrical stimulation of their nerves were evaluated. In 10 individuals, earlier stimulation techniques used to evoke M-responses ('bipolar needle' and 'surface' techniques) were compared with a previously undescribed 'monopolar needle' technique. The monopolar needle technique proved to give more stable stimulating conditions than the earlier techniques. Selective stimulation of the masseteric nerve or simultaneous stimulation of the masseteric and deep temporal nerves were found, depending on the position of the stimulating electrode.
