In this case study, a geriatric patient who had an 18-year history of hemifacial spasm was given EMG-biofeedback-assisted relaxation training. No formal speech therapy was provided. Our results confirmed two hypotheses: (a) The patient would learn to reduce frontalis EMG and facial spasm with and then without biofeedback, and (b) as a result, speech would be markedly improved. At both the 1-month and 15-month follow-up the patient retained the ability to relax his facial muscles with similar carry-over to speech. Possible neurophysiologic mechanisms of action mediating the feedback training are discussed.
在本病例研究中，一名有18年半面痉挛病史的老年患者接受了肌电图生物反馈辅助放松训练。未提供正式的言语治疗。我们的结果证实了两个假设：(a) 患者将学会在有生物反馈和无生物反馈的情况下减少额肌肌电图活动和面部痉挛，以及 (b) 结果，言语将得到显著改善。在1个月和15个月的随访中，患者均保持了放松面部肌肉的能力，且对言语有类似的延续作用。文中讨论了介导反馈训练的可能神经生理作用机制。
