To test if dreams contain remote or never-experienced motor skills, we collected during 6 weeks dream reports from 15 paraplegics and 15 healthy subjects. In 9/10 subjects with spinal cord injury and in 5/5 with congenital paraplegia, voluntary leg movements were reported during dream, including feelings of walking (46%), running (8.6%), dancing (8%), standing up (6.3%), bicycling (6.3%), and practicing sports (skiing, playing basketball, swimming). Paraplegia patients experienced walking dreams (38.2%) just as often as controls (28.7%). There was no correlation between the frequency of walking dreams and the duration of paraplegia. In contrast, patients were rarely paraplegic in dreams. Subjects who had never walked or stopped walking 4-64 years prior to this study still experience walking in their dreams, suggesting that a cerebral walking program, either genetic or more probably developed via mirror neurons (activated when observing others performing an action) is reactivated during sleep.
为了测试梦境是否包含远程或从未经历过的运动技能，我们在 6 周的时间里从 15 名截瘫患者和 15 名健康受试者那里收集了梦境报告。在 9/10 名脊髓损伤患者和 5/5 名先天性截瘫患者中，报告在梦境中出现了自愿的腿部运动，包括行走（46%）、跑步（8.6%）、跳舞（8%）、站立（6.3%）、骑自行车（6.3%）和运动（滑雪、打篮球、游泳）。截瘫患者经历行走梦的频率（38.2%）与对照组（28.7%）一样频繁。行走梦的频率与截瘫的持续时间之间没有相关性。相比之下，患者在梦中很少出现截瘫。在这项研究之前从未行走或停止行走 4-64 年的受试者仍会在梦中行走，这表明大脑行走程序（可能是遗传的，也可能更可能是通过镜像神经元发展的，当观察到他人执行动作时激活）在睡眠中被重新激活。
