A 19-year-old left-handed man, who was raised by deaf-mute parents and learned sign language concurrently with normal speech, sustained a traumatic cerebral contusion. He subsequently had no evidence of apraxic, visual-spatial, or sensorimotor deficits of the left limbs with which he was accustomed to use signs. Globally aphasic with a dense right hemiparesis, he initially recovered sign language to a greater degree than spoken language with a reversal on follow-up observations. Receptive skills improved to a greater degree than expressive skills with no marked difference between verbal and sign language, but with natural signs better preserved than finger spelling.
一名19岁的左撇子男性，由聋哑父母抚养长大，在学习正常语言的同时也学习了手语，他遭受了外伤性脑挫伤。随后，他习惯用手语的左上肢没有失用、视觉空间或感觉运动功能障碍的迹象。他整体失语且右侧肢体严重偏瘫，最初手语恢复程度高于口语，但在后续观察中情况出现了反转。接受能力的改善程度高于表达能力，口语和手语之间没有明显差异，但自然手语比指拼保留得更好。
