Scientific analysis of medical qigong

There are a lot of inner Qigong forms, but not so many about the healing sounds. This paper tries to explore the effect of the six healing sounds in combination with Guo Lin's New Qigong concerning sounds, and analyze the changing physiological data before and after the exercises.

The Six Healing Sounds:

Table 1 shows the time change of the sound intensity and heart beating. The ratio of the five sounds - Xu, He, Hu, Si and Chui increases. Qi is pronounced shortly, but the ascending phenomon is seen in the fourth pulse ratio. The R-potential of ECG indicates the change of the autonomic nervous system. The potential of the sympathetic nerve decreases. While that of the parasympathetic nerve increases.

Table 2 shows the change of R-potential when the six healing sounds are practiced. When the sounds are sent out, all the potential is lowered. However, when Qi is sent out, more change is found in the sympathetic nerves, then the He and chui sounds. It indicates the intensity of sound affects the autonomic nerves. When the exercise is carried out, a laser probe is placed on the cervical artery.

Table 3 shows that the six sounds may have different influences on blood pressure and blood flow. Different sounds changes volume of blood flow. When the six sounds are sent out, stronger waves of EEG is seen and when sounds are stopped, the forehead is full of a wave, indicating one has entered a relaxing state.

Guo Lin's New Qigong:

We have mainly studied the sound of Ha with three high pitched Ha, two low pitched Ha and a long high pitched Ha. Highest brain wave is seen when a high pitched Ha is sent out and the higher potential is found in the right brain. When a short sound of Ha is sent out, higher potential is seen on the forehead and the right brain. When a long or low Ha is sent out, no obvious change of the brain wave is seen, but when the sound stops, brain wave increases significantly.

From above we can see that the sounds all affect the sympathetic and parasympathetic nerves to some degree.
