背景周围神经刺激可诱导皮质适应，因为它在刺激后立即改善慢性中风患者的捏强度。Objective.检测外周感觉刺激对急性和亚急性卒中患者捏强度的影响。方法.中风患者（N = 20），发病不到6个月前，可以自愿捏拇指食指参加了一项随机，单盲，对照研究。10名患者在腕部的正中神经和尺神经上同时接受2小时的电刺激，达到欣赏感觉异常的水平（外周感觉刺激组）。10名对照患者接受感知水平的刺激（假对照组）。在刺激之前和刺激之后立即测试拇指垫对轻瘫手的食指的尖端和外侧的捏强度和动作研究臂测试。结果两组的外侧和尖端捏强度均显著增加（P
Background. Peripheral nerve stimulation may induce cortical adaptations as it improves pinch strength in chronic stroke patients immediately after stimulation. Objective. Test the effects of peripheral sensory stimulation on pinch strength in patients with acute and subacute stroke. Methods. Stroke patients (N = 20) who had onset less than 6 months previously and could voluntarily pinch the thumb to the index finger participated in a randomized, single-blinded, controlled study. Ten patients received 2 hours of simultaneous electrical stimulation over the median and ulnar nerves at the wrist to the level of appreciating paresthesias (peripheral sensory stimulation group). Ten control patients received stimulation to the level of perception (sham-control group). Pinch strength of the thumb pad to tip and to lateral side of the index finger of the paretic hand and the Action Research Arm test were tested before and immediately after the stimulation. Results. Lateral and tip pinch strength were significantly increased in both groups (P
