“…This report implies that the arousal level can be diminished by SGB. Since LISG including Xe-LISG provides therapeutic effects similar to SGB [5][6][7]10) , the arousal level may be diminished by Xe-LISG. Empirically, it is not surprising that a diminished arousal level causes instability during standing.…”

Abstract. [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 up immediately and maintained quiet standing for 1 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 HF 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.

“…Photobiostimulation effects of near-infrared (NIR) laser irradiation have been known for almost 40 years [7]. Many studies have shown increased blood flow in various organs during and after NIR laser irradiation [7][8][9][10]. Recently, it has been reported that NIR laser irradiation is effective for controlling cerebral ischemia in vivo and clinically [11][12][13][14].…”

Abstract.[Purpose] The purpose of the present study was to investigate the effects of transcutaneous xenon light irradiation around the stellate ganglion on autonomic functions.[Subjects] Thirty healthy volunteers were the subjects.[Methods] The subjects underwent two experimental sessions: 1) 10-minute xenon light irradiation to the bilateral stellate ganglions in a comfortable supine position (Xe-LISG); and 2) 10-minute rest in the same position as Xe-LISG (control). The low frequency (0.04-0.15 Hz) power (LF) and ratio of LF to the high frequency (0.15-0.40 Hz) power (LF/HF) obtained from power spectral analysis of R-R intervals and skin temperatures of the upper and lower extremities (UE and LE) were examined.[Results] Although no significant changes of HF and LF/HF were observed before and after the control, HF after Xe-LISG was significantly increased compared with that before Xe-LISG, and LF/HF after Xe-LISG was significantly decreased compared with that before Xe-LISG. Additionally, although the UE skin temperature during Xe-LISG tended to be higher than that during the control, the LE skin temperature during Xe-LISG tended to be lower than that during the control.[Conclusion] These results suggest that Xe-LISG inhibits sympathetic activity and induces not only an increase in the UE skin blood flow, but also a decrease in the LE skin blood flow.
