BACKGROUND
The somatosensory evoked blink response (SBR) is a characteristic reflex blink elicited by electrical stimulation of peripheral nerves or other anatomical sites.
METHODS
139 patients with neurological disorders were examined for presence of the SBR. Although the SBR was not usually elicitable, it was present in a subset of patients with Parkinson's disease and with hemifacial spasm. It was also present in a patient with Guillain-Barré syndrome before the recovery phase. The latency of the EMG activities responsible for the SBR was significantly shorter than that of the startle blink.
CONCLUSIONS
The SBR is not a variant of the startle blink, but is a release phenomenon transmitted via the brainstem reticular formation. This response may be clinically relevant in disorders associated with brainstem lesions and abnormal blinking.
背景
体感诱发性眨眼反应（SBR）是通过对外周神经或其他解剖部位进行电刺激而引发的一种特征性反射性眨眼。
方法
对139例神经系统疾病患者进行了SBR检查。虽然SBR通常难以引出，但在一部分帕金森病和半面痉挛患者中存在。在吉兰 - 巴雷综合征患者恢复阶段之前也有该反应。负责SBR的肌电活动潜伏期明显短于惊吓性眨眼的潜伏期。
结论
SBR不是惊吓性眨眼的变体，而是通过脑干网状结构传递的一种释放现象。这种反应在与脑干病变和异常眨眼相关的疾病中可能具有临床意义。
