To investigate the effect of low level laser therapy (LLLT) on PC6 acupuncture point in suppressing gag reflex, regulating pulse rates and oxygen saturation, thereby reducing the anxiety levels.
A total of 40 patients who demonstrated hyperactive gag reflex in the age group of 4-14 years were included in the study. In Group A (20 patients), maxillary impression was recorded. In the second step, PC6 acupuncture point was stimulated with LLLT followed by recording of second maxillary impression. In group B (20 patients), steps were reversed. Gag reflex, anxiety levels, pulse rate and oxygen saturation levels were assessed.
Values of pulse rate and oxygen saturation were regulated to normal, signifying lowered anxiety levels. Gag reflex was also significantly decreased after stimulating PC6 acupuncture point with LLLT.
LLLT on PC6 point was found to be effective in lowering anxiety levels as observed by faces modified anxiety rating scale. Further, it was authenticated as the pulse rates were significantly reduced and oxygen saturation levels were significantly increased. Also, gag reflex was significantly controlled when LASER stimulation was done at PC6.
探讨低强度激光疗法（LLLT）对双侧内关穴在抑制咽反射、调节脉搏率和血氧饱和度从而降低焦虑水平方面的作用。
本研究纳入了40例年龄在4至14岁之间咽反射亢进的患者。A组（20例患者）记录上颌印模。第二步，用低强度激光疗法刺激双侧内关穴，然后记录第二次上颌印模。B组（20例患者）步骤相反。评估咽反射、焦虑水平、脉搏率和血氧饱和度水平。
脉搏率和血氧饱和度值调节至正常，表明焦虑水平降低。用低强度激光疗法刺激双侧内关穴后，咽反射也显著降低。
通过面部改良焦虑评定量表观察发现，低强度激光疗法作用于双侧内关穴对降低焦虑水平有效。此外，由于脉搏率显著降低且血氧饱和度水平显著升高，这一结果得到了验证。而且，当在双侧内关穴进行激光刺激时，咽反射得到了显著控制。
