[目的] 本研究调查星状神经节周围经皮氙光照射后是否会出现站立不稳定。 【研究对象】以30名健康志愿者为研究对象。 [方法] 受试者接受两次实验：1）舒适仰卧位双侧星状神经节周围10分钟氙灯照射（Xe-LISG）； 2) 在与 Xe-LISG（对照）相同的位置休息 10 分钟。在 Xe-LISG 和对照之后，他们立即站立 LIP 并保持安静站立 1 分钟。研究了基于 R-R 间隔的低频功率 (LF) 和 LF 与高频功率之比 (LF/HF)，以及安静站立时足部压力中心偏移的总长度 (LNG) 和矩形面积 (REC)。 [结果]虽然对照前后I-IF和LF/HF没有观察到明显变化，但Xe-LISG后HF显着大于Xe-LISG前，Xe-LISG后LF/HF显着低于Xe-LISG前。此外，虽然 Xe-LISG 后的 REC 与对照后的 REC 之间没有观察到显着差异，但 Xe-LISG 后的 LNG 明显长于对照后。 [结论] 这些结果表明，Xe-LISG 不仅会导致副交感神经优势和交感神经抑制，还会导致 Xe-LISG 后站立时的不稳定。
[Purpose] This study investigated whether instability during standing occurs just after transcutaneous xenon light irradiation around the stellate ganglion. [Subjects] Thirty healthy Volunteers were the subjects. [Methods] The subjects underwent two experimental sessions: 1) 10-minute xenon light irradiation around the bilateral stellate ganglions in a comfortable Supine position (Xe-LISG); and 2) 10-minute rest in the same position as Xe-LISG (control). After Xe-LISG and the control, they stood LIP immediately and maintained quiet standing for I minute. The low frequency power (LF) and ratio of LF to the high frequency power (LF/HF) based on R-R intervals, and the total length (LNG) and rectangular area (REC) of the excursion of the center of foot pressure during quiet standing were examined. [Results] Although no significant changes of I-IF and LF/HF were observed before and after the control, HF after Xe-LISG was significantly greater than that before Xe-LISG, and LF/HF after Xe-LISG was significantly lower than that before Xe-LISG. Additionally, although no significant difference was observed between REC after Xe-LISG and that after the control, LNG after Xe-LISG was significantly longer than that after the control. [Conclusion] These results Suggest that Xe-LISG causes not only parasympathetic predominance and sympathetic Suppression but also instability during standing just after Xe-LISG.
