This paper describes a single-subject experiment testing two methods of using EMG biofeedback in the treatment of TMJ dysfunction. Following a baseline period, electrodes were placed on the left and right masseter muscles, and the subject was taught general relaxation of this area using visual biofeedback. Although data supported the conclusion that the subject had indeed learned to relax, this was not associated with any change in the report of pain or dysfunction. Equalization training, the goal being to equalize the levels of EMG in the right and left masseter muscles, was then begun. Once the patient had learned to maintain equal levels of EMG, relaxation was then re-introduced. This produced substantial decreases in her reported pain, both within the session and averaged across days for the time between sessions. These treatment gains were maintained at 2-month follow-up.
本文描述了一项单受试者实验，该实验测试了两种使用肌电图生物反馈治疗颞下颌关节功能障碍的方法。在基线期之后，将电极放置在左右咬肌上，并使用视觉生物反馈教导受试者对该区域进行一般性放松。尽管数据支持受试者确实学会了放松这一结论，但这与疼痛或功能障碍报告的任何变化均无关联。然后开始进行均衡训练，目标是使左右咬肌的肌电图水平均衡。一旦患者学会维持肌电图的均衡水平，便再次引入放松训练。这使得她在治疗期间以及各疗程之间的数天平均报告疼痛大幅减轻。这些治疗效果在2个月的随访中得以维持。
