The long-term effect of daily somatosensory stimulation with transcutaneous electrical nerve stimulation (TENS) on reorganization of the motor cortex was investigated in a group of neurologically intact humans. The scalp representation of the corticospinal projection to the finger (APB, ADM) and forearm (FCR, ECR) muscles was mapped by means of transcranial magnetic stimulation (TMS) before and after a 3-week intervention period, using map area and volume, and topographical overlaps between the cortical motor representations of these muscles as primary dependent measures. Findings revealed a significant increase in cortical motor representation of all four muscles for the TENS group from pre to posttest (all, P ≤ 0.026). No significant changes in cortical motor representations were observed in the control group. The present observations highlight the potential benefit of sensory training by means of TENS as a useful complementary therapy in neurorehabilitation.
研究了一组神经完整的人类中，每日躯体感觉刺激经皮电神经刺激（TENS）对运动皮层重组的长期影响。通过经颅磁刺激（TMS），在 3 周干预期前后，使用图区和体积，以及这些肌肉的皮质运动代表之间的拓扑重叠，来映射皮质脊髓投射到手指（APB、ADM）和前臂（FCR、ECR）肌肉的头皮代表。结果显示，TENS 组从预测试到后测试，所有 4 块肌肉的皮质运动代表均显著增加（均，P ≤ 0.026）。对照组的皮质运动代表没有明显变化。本研究结果强调了 TENS 作为神经康复中有用的补充疗法，通过感觉训练来获得潜在益处。
