Effects of biofeedback training on tonic masticatory neck reflex: a case report.
Biofeedback training to reduce muscle tension lowered not only the spontaneous activity but also the tonic neck reflex in the jaw closing muscles. Tolperisone-HCl, which may inhibit the gamma system, inhibited the tonic masticatory neck reflex, but did not reduce the patient's spontaneous activity of the jaw closing muscles in this case. Biofeedback training may be considered to reduce the gamma as well as alpha motor systems.
