运动功能的缺陷，包括行走速度和平衡的障碍，是许多不完全性脊髓损伤（iSCI）患者的主要问题。然而，目前尚不清楚哪种类型的训练模式在改善iSCI患者的平衡，特别是动态平衡方面更有效。本研究的目的是确定阳极经皮脊髓直流电刺激（tsDCS）是否可以促进iSCI患者在行走过程中学习平衡控制。15名iSCI患者参加了这项研究，并在两个阶段进行了测试（即，tsDCS和假条件）。每个阶段包括1分钟无刺激或扰动的踏车行走（基线），10分钟阳极tsDCS或假刺激行走，配对双侧骨盆扰动（适应），最后2分钟无刺激和扰动的行走（适应后）。结果测量是动态平衡，使用最小稳定性边缘（MoS）和腿部肌肉肌电图进行评估。与假手术组相比，参与者在阳极tsDCS条件的晚期适应期表现出较小的MoS（p = 0.041），并且该MoS预期在适应后早期保留（p = 0.05）。此外，在后期适应期和适应后期，与假手术相比，阳极tsDCS条件下髋外展肌的肌肉活动更大（p < 0.05）。这项研究的结果表明，阳极tsDCS可以调节运动适应骨盆扰动，并促进学习动态平衡控制的个人与iSCI。
Deficits in locomotor function, including impairments in walking speed and balance, are major problems for many individuals with incomplete spinal cord injury (iSCI). However, it remains unclear which type of training paradigms are more effective in improving balance, particularly dynamic balance, in individuals with iSCI. The purpose of this study was to determine whether anodal transcutaneous spinal direct current stimulation (tsDCS) can facilitate learning of balance control during walking in individuals with iSCI. Fifteen individuals with iSCI participated in this study and were tested in two sessions (i.e., tsDCS and sham conditions). Each session consisted of 1-minute of treadmill walking without stimulation or perturbation (baseline), 10-minute of walking with either anodal tsDCS or sham stimulation, paired with bilateral pelvis perturbation (adaptation), and finally 2-minute of walking without stimulation and perturbation (post-adaptation). The outcome measures were the dynamic balance, assessed using the minimal margin of stability (MoS), and electromyography of leg muscles. Participants demonstrated a smaller MoS during the late adaptation period for the anodal tsDCS condition compared to sham (p = 0.041), and this MoS intended to retain during the early post-adaptation period (p = 0.05). In addition, muscle activity of hip abductors was greater for the anodal tsDCS condition compared to sham during the late adaptation period and post-adaptation period (p < 0.05). Results from this study suggest that anodal tsDCS may modulate motor adaptation to pelvis perturbation and facilitate learning of dynamic balance control in individuals with iSCI.
