We evaluated biofeedback rehabilitation in patients with severe chronic unilateral facial paralysis, who had intact facial-motor innervation (House grades 3 to 5). Recovery of facial function was characterized (1) by grading facial movement symmetry, and (2) by counting the number of muscles exhibiting synkinesis during maximal execution of selected facial movements (e.g., smiling). Facial function in 21 patients typically improved by one House grade. Facial symmetry recovered rapidly during the first 5 months of treatment, and then improved more slowly. However, during this latter period, examination of the relationship between symmetry and synkinesis (visualized by a graph plotting symmetry grades on the x-axis, against the number of synkinetic muscles on the y-axis) indicated that overall facial control was improving even when House grading suggested that it was not. Such information should aid facial retraining and may clarify understanding of underlying rehabilitation mechanisms.
我们评估了严重慢性单侧面瘫患者（面部运动神经支配完整，House分级为3至5级）的生物反馈康复治疗效果。面部功能的恢复表现为：（1）对面部运动对称性进行分级；（2）在最大程度执行选定面部动作（如微笑）时，计算出现联带运动的肌肉数量。21例患者的面部功能通常改善了一个House分级。治疗的前5个月，面部对称性迅速恢复，之后恢复速度减慢。然而，在这一后期阶段，通过检查对称性与联带运动之间的关系（通过绘制以x轴表示对称性分级、y轴表示联带运动肌肉数量的图表来直观呈现）表明，即使House分级显示面部功能没有改善，但整体面部控制仍在改善。这些信息应有助于面部再训练，并可能澄清对潜在康复机制的理解。
