Abstract：
CONCLUSIONS: This scoping review aims to summarize the technical strategies for obtaining trigeminocervical reflex (TCR) and trigeminospinal reflex (TSR) responses. Studies published on TCR or TSR elicitation in humans through electrical stimulation of trigeminal nerve branches were eligible for this scoping review. The data of interest included stimulation parameters, site of stimulation, recording parameters, and the feasibility of TCR and TSR elicitation, in healthy participants. Short-latency TCR responses were regularly obtained in both anterior and posterior neck muscles after electrical stimulation of the supraorbital and infraorbital nerves under voluntary muscle activation. However, without voluntary muscle activation, we found evidence of elicitation of short-latency TCR components only in the posterior neck muscles after supraorbital or infraorbital nerve stimulation. Long-latency TCR responses were regularly obtained in the anterior and posterior neck muscles in studies that evaluated this technique, regardless of the trigeminal branch stimulation or muscle activation status. Short-latency TSR components were not obtained in the included studies, whereas long-latency TSR responses were regularly recorded in proximal upper limb muscles. This scoping review revealed key heterogeneity in the techniques used for TCR and TSR elicitation. By summarizing all the methodological procedures used for TCR and TSR elicitation, this scoping review can guide researchers in defining optimized technical approaches for different research and clinical scenarios.
摘要：
结论：本范围综述旨在总结获得三叉神经宫颈反射（TCR）和三叉神经脊髓反射（TSR）反应的技术策略。发表的关于通过电刺激三叉神经分支在人类中引起TCR或TSR的研究符合此范围审查的条件。感兴趣的数据包括刺激参数，刺激部位，记录参数,以及TCR和TSR激发的可行性，健康的参与者在自愿性肌肉激活下，对眶上和眶下神经进行电刺激后，在颈前后肌中定期获得短潜伏期TCR反应。然而,没有自愿的肌肉激活，我们发现仅在眶上或眶下神经刺激后的颈后肌肉中诱发短潜伏期TCR成分的证据.在评估该技术的研究中，经常在颈前后肌肉中获得长潜伏期的TCR反应，无论三叉神经分支刺激或肌肉激活状态。在纳入的研究中未获得短潜伏期TSR成分，而长潜伏期TSR反应定期记录在上肢近端肌肉中。这项范围审查揭示了TCR和TSR激发技术的关键异质性。通过总结用于TCR和TSR启发的所有方法学程序，这项范围审查可以指导研究人员为不同的研究和临床方案定义优化的技术方法.
