Electromyographic (EMG) sensory feedback therapy (SFT) was used in the neuromuscular retraining of the nonfunctional upper extremity in five chronic left cerebrovascular accident (CVA) patients with impaired expressive and auditory comprehension. Speech diagnoses included global, moderate-to-severe Broca, and Wernicke aphasias. These patients had experienced increased despondency associated with previous therapy failures and often had indicated that they wished to have their involved extremity amputated, so that it would no longer be in the way. In this study, specific behavioral training strategies to increase patient involvement were used, including: general relaxation, modified SFT instruction, and home exercises, which were supported by family and/or friends. After an average of 50 therapy sessions, all patients were successfully retrained to use their right upper extremity at the gross-assist level. This resulted in feelings of increased self-esteem to the extent that amputation was no longer requested. It is concluded that EMG SFT can be beneficial in the neuromuscular reeducation of paretic upper extremity muscles of CVA patients with expressive aphasia and (impaired) auditory comprehension.
肌电图（EMG）感觉反馈疗法（SFT）被用于对5名慢性左脑血管意外（CVA）患者的无功能上肢进行神经肌肉再训练，这些患者存在表达性和听觉理解障碍。言语诊断包括完全性、中度至重度布罗卡失语症和韦尼克失语症。这些患者因先前治疗失败而愈发沮丧，且常表示希望截肢受累肢体，以免其碍事。在本研究中，采用了特定的行为训练策略来提高患者的参与度，包括：全身放松、改良的SFT指导以及家庭锻炼，并得到家人和/或朋友的支持。平均经过50次治疗后，所有患者均成功接受再训练，能够在粗大辅助水平上使用其右上肢。这使他们的自尊感增强，以至于不再要求截肢。得出的结论是，EMG SFT对患有表达性失语症和（受损）听觉理解的CVA患者的麻痹上肢肌肉进行神经肌肉再教育可能有益。
