摘要:

运动完全性脊髓损伤患者损伤仍存在对脊髓水平以下肌肉的控制能力。然而,由于长期不运动,最初尝试激活这些肌肉可能仍无法控制。作者既往一项研究已发现对完全脊髓损伤患者进行短暂的被动活动可其导致执行意志任务时肌电通道激活的增加。因此,为进一步了解运动完全性脊髓损伤患者在执行意志控制任务期被动活动对表面肌电图的影响,试验招募了招募了11例完全性胸椎脊髓损伤患者,并在被动运动后比较了8块主要腿部肌肉的表面肌电图数据。结果显示,与基线相比,短暂的被动活动显著增加了表面肌电通道数量和激活频率显著增加,且被动活动后表面肌电图振幅的累积均方根存在增加趋势。这些发现表明,短暂的被动活动可增强肌电检测任务时的自主肌肉激活的能力,从而提高评估完全性脊髓损伤患者残余控制能力的敏感性。

Abstract: Patients with complete spinal cord injury retain the potential for volitional muscle activity in muscles located below the spinal injury level. However, because of prolonged inactivity, initial attempts to activate these muscles may not effectively engage any of the remaining neurons in the descending pathway. A previous study unexpectedly found that a brief clinical round of passive activity significantly increased volitional muscle activation, as measured by surface electromyography. In this study, we further explored the effect of passive activity on surface electromyographic signals during volitional control tasks among individuals with complete spinal cord injury. Eleven patients with chronic complete thoracic spinal cord injury were recruited. Surface electromyography data from eight major leg muscles were acquired and compared before and after the passive activity protocol. The results indicated that the passive activity led to an increased number of activated volitional muscles and an increased frequency of activation. Although the cumulative root mean square of surface electromyography amplitude for volitional control of movement showed a slight increase after passive activity, the difference was not statistically significant. These findings suggest that brief passive activity may enhance the ability to initiate volitional muscle activity during surface electromyography tasks and underscore the potential of passive activity for improving residual motor control among patients with motor complete spinal cord injury.
