Discussion of qigong effect on PD patients in clinic and P33 which is an auditory event related potential

In this research of ERPs P3oo, we employed the method of short sound stimulation with two agitating and stimulating systems, two separate “time-analysis windows” and with attention to the probability of target and non -target stimulation.

We successfully recorded P300 of 24 normal controls and those of 30 Parkinson disease patients before and after practicing Qigong. We also recorded the webster's scale of 33 Parkinson disease patients practicing qigong for one year.

The primary results are as follows:

a. In comparison with the normal controls, P300 indexes of Parkinson Disease are perceived, among which the lengthening latency of target stimulating P3 of Parkinson Disease was the most distinctive one; and the amplitude of P3 was higher than those of the control group.
b. Comparing with the records taken before the self- treatment by practicing qigong, the latency of target stimulating P3 of Parkinson Disease shortened significantly.
c. The Webster's score indicated that Parkinson Disease patients conditions have improved in terms of the clinical symptom by practicing qigong and implies to us the positive treatment effect of qigong.
