The present case study investigated the efficacy of feedback in restoring muscle control to facial muscles which had been affected by Bell palsy. The subject, a woman, was provided an analog tone as feedback for modifying the muscle activity on the paralyzed (right) side of her face to match that of her nonaffected (left) side. The results showed a statistically significant shift in muscle activity in masseter, zygomaticus, and orbicularis oculi muscles. Post-treatment levels closely approximated the nonaffected side, and resulted in more normal facial characteristics with respect to jaw position and symmetry of smiling. Bidirectional control of the zygomaticus was also demonstrated.
本案例研究调查了反馈对恢复受贝尔面瘫影响的面部肌肉控制能力的功效。受试者为一名女性，她被给予一种模拟音调作为反馈，以调整其面部瘫痪（右侧）一侧的肌肉活动，使其与未受影响（左侧）一侧的肌肉活动相匹配。结果显示，咬肌、颧肌和眼轮匝肌的肌肉活动出现了具有统计学意义的变化。治疗后的水平与未受影响的一侧非常接近，并且在下巴位置和微笑对称性方面产生了更正常的面部特征。还证明了颧肌的双向控制。
