This study focused on the effects of laser acupuncture (LA) and manual acupuncture (MA) at different acupoints on gastric motility and heart rate variability (HRV) simultaneously to elucidate the site specific effects of acupoints and the correlation between changes of gastric motility and low frequency/high frequency (LF/HF) ratio. Gastric motility and HRV were recorded before and during MA or LA. Stimulating PC-6 or ST-36 significantly enhanced gastric motility, while BL-21 caused no changes. In contrast, MA or LA at CV-12 significantly suppressed gastric motility. Stimulating PC-6 or ST-36 significantly increased heart rate (HR), while CV-12 or BL-21 induced no significant changes of HR. Stimulating PC-6 significantly increased LF/HF, while ST-36, CV-12, or BL-21 induced no significant effects. These results indicated that there was acupoint specificity in the effects of acupuncture on gastric motility and HRV. The stimulatory effect of MA and LA at PC-6 and ST-36 on HR was associated with sympathetic activity. The stimulatory effect of MA or LA at PC-6 or ST-36 on gastric motility was associated with vagal activity. Laser needle can be used as an alternative stimulation therapy.
本研究旨在同时观察激光针灸(LA)和手针刺激不同穴位对胃动力和心率变异性(HRV)的影响,以阐明穴位的特定作用及胃动力变化与低频/高频(LF/HF)比值的相关性。在刺激过程中记录胃动力和 HRV 的变化。刺激 PC-6 或 ST-36 可显著增强胃动力,而刺激 BL-21 则无明显影响。相反,刺激 CV-12 可显著抑制胃动力。刺激 PC-6 或 ST-36 可显著增加心率(HR),而刺激 CV-12 或 BL-21 则对 HR 无明显影响。刺激 PC-6 可显著增加 LF/HF,而刺激 ST-36、CV-12 或 BL-21 则无明显影响。这些结果表明,针刺对胃动力和 HRV 的影响存在穴位特异性。手针和 LA 刺激 PC-6 和 ST-36 对 HR 的影响与交感神经活动有关。手针和 LA 刺激 PC-6 或 ST-36 对胃动力的影响与迷走神经活动有关。激光针可作为替代刺激治疗方法。
