创伤性脊髓损伤（SCI）破坏了脊髓和棘上通路，这一过程反映在表面肌电图（sEMG）的变化上。肌电图是对当前临床测试的一种有益补充，它可以非常详细地捕捉到残留的运动指令——包括在损伤水平以下、看似没有运动活动的肌肉中。在这篇全面的综述中，我们试图描述脊髓损伤后肌电特征是如何改变的。我们进行了系统的文献检索，然后对脊髓损伤后的表面肌电信号分析技术和信号特性进行了综述。我们发现，早期的报告主要集中在肌电信号模式的定性分析上，并演变为半定量评分和更详细的基于幅度的量化。尽管如此，最近的研究仍然局限于基于幅度的肌电图分析，并且有机会更广泛地表征信号的时域和频域特性，并充分利用高密度肌电图技术。我们建议在脊髓损伤后的神经生理评估中纳入更广泛的信号特性，并对这些表面肌电信号特性与潜在生理学之间的关系有更深入的了解。增强的肌电图分析有助于更完整地描述脊髓损伤对上下运动神经元功能的影响及其相互作用，并有助于理解神经调节或运动治疗后变化的机制。在线版本包含补充材料，可在10.1186/s12984-021-00888-2获得。
Traumatic spinal cord injury (SCI) disrupts spinal and supraspinal pathways, and this process is reflected in changes in surface electromyography (sEMG). sEMG is an informative complement to current clinical testing and can capture the residual motor command in great detail—including in muscles below the level of injury with seemingly absent motor activities. In this comprehensive review, we sought to describe how the sEMG properties are changed after SCI. We conducted a systematic literature search followed by a narrative review focusing on sEMG analysis techniques and signal properties post-SCI. We found that early reports were mostly focused on the qualitative analysis of sEMG patterns and evolved to semi-quantitative scores and a more detailed amplitude-based quantification. Nonetheless, recent studies are still constrained to an amplitude-based analysis of the sEMG, and there are opportunities to more broadly characterize the time- and frequency-domain properties of the signal as well as to take fuller advantage of high-density EMG techniques. We recommend the incorporation of a broader range of signal properties into the neurophysiological assessment post-SCI and the development of a greater understanding of the relation between these sEMG properties and underlying physiology. Enhanced sEMG analysis could contribute to a more complete description of the effects of SCI on upper and lower motor neuron function and their interactions, and also assist in understanding the mechanisms of change following neuromodulation or exercise therapy.
