Therefore, chaos analysis was applied to these fluctuating data , and the visualization and analysis of the undulation wave were tried according to (1) a change of sphygmogram in meditation or concentration, (2) a change of sphygmogram with the acupuncture on Ho-ku stimulation and (3) a change of H-wave repetitive-evoked electro-myography (RE-EMG) under the influence of acupuncture anesthesia (A.A.). Each undulation wave was shown as an attractor. As an exponent which shows the human body state, the process was shown by Lyapunov exponent. So, it is possible to show the stage of mental psychology and the effect of acupuncture techniques (the tonification method and the sedation method, acupuncture point, stimulation method etc.). It seems that the effect of acupuncture has an influence on the undulation of human body and acupuncture is effective for restoring the condition of human body. A.A. blocked the control from the central nerve and affected the exercise system. Meditation practise showed the similar chaos state such as Qigong practise , but chaos state in an imagination practise was different.
