Clinical studies are reviewed to illustrate that qigong can improve the health of people suffering from different chronic medical problems that accelerate the aging process. The focus is on personal practice of qigong exercise to improve many functions of the body, improve health and reverse aging. Clinical studies suggest that a combination therapy of qigong and druges is superior to drug therapy alone, as indicated in the case of two diseases, hypertension and cancer. Qigong therapy can complement Western medicine in many ways to improve healthcare.

The Electroencephalographies (EEGs) of 38 Qigong practitioners (20 Chinese and 18 Japanese) and 29 non-practitioners were measured. During Qigong, an increase in θ waves and α waves is reported. However, θ waves appeared in the EEG of only eight Qigong practitioners in the resting state (21.1%), of six (21.4%) while emitting Qi (28 experiments), and of seven (36.8%) during Qigong meditation (19 experiments). Those appeared broadly in a period of double or triple wavelength of θ and only a few times during an experimental session of about ten minutes. As compared with the θ appearance rate of non-practitioners which was 37.9% during receiving Qi from Qigong practitioners, that on the Qigong practitioners was not very large. Also the θ wave during Qigong did not increase from those during resting. The power spectra indicate that the peak frequency of α waves during Qigong increased. For 38 Qigong practitioners, the mean value was 9.55±0.14 Hz during resting with eyes closed, and those increased to 9.74±0.18 Hz while emitting Qi and to 10.05±0.22 Hz during quiet Qigong meditation. These data included Qigong practitioners whose α frequency decreased with respect to the resting state, seven during external Qi (26.9%) and seven during internal Qi (41.2%). Their α frequency in the resting state was greater than the average. These results were compared with those from eight TM practitioners whose α frequency slightly incerased during meditation, and with two priests whose α frequency decreased and whose θ waves appeared during Buddhist meditation. These results suggest that the level of consciousness in Qigong practitioners corresponds to that of TM practitioners who meditate by chanting a mantra in the mind. The α deceleration type may correspond to the Buddhiat meditator. However, there is no correlation between the deceleration type and the θ appearance type.

In order to verify that a subject's brain is able to identify selected sounds, even if the subject can not identify the selected sounds significantly by the normal auditory sense, a series of trials were performed on the subject who tried to identify the sound selected previously at random by computer while listening to four sounds generated dur-ing trials. This paper will demonstrate that the subject's significant shift of latency was detected on his auditory brain evoked potential peak while he listened to the selected unknown targets, and will suggest the possibility of unknown information transfer in the subconsciusness.

A sender and a percipient were separately located in two sense-shielded rooms and extrasensory transfer of information attempted during which the electroencephalogram of the percipient was measured. The sender sent information dur-ing the randomly selected first or second half of a two-minute period, while the percipient attempted to guess both the information sent, and the sending time zone. Over 20 trials, the percipient was unable to guess the correct sending time zones with any statistical significance, but did show a statistically significant difference in the alpha wave ampli-tude in the electroencephalogram between sending and non-sending time zones. This sug-gests the existence of the extrasensory information transfer in the subconscious.

Convenient parameters were given to evaluate the effects of the external stimulations on human body, on the basis of analyses of the human meridians using square wave voltage responses. Besides the conventional parameters which show the "Qi" flow or the activity of the autonomic nervous, a parameter was introduced to represent the balance of whole meridians.

Excluding the visual and suditory sensations of the subject, the changes in the rectangular pulse current when applied on the various acupoints were measured under healing 18 trials. Healers consisted of four males and six females, while the subjects were four males, and four females. The results were analyzed statistically, and it was found that the parameters of response, the BP and AP, changed synchronously as healing began. This result suggested that the existence of unknown energy other than five sensations.

In China, one of the branches of qi-gong is external qi-gong and this is an accepted traditional oriental method used for a method for curing diseases such the same as the western medical method. Qi-gong anesthesia is included as one type of the external qi-gong. However, the mechanism of the qi-gong anesthesia, is not sufficiently explained. In this paper, we present the results of the measurement of both persons; one being a qi-gong master, Professor Chu, the other the qi-gong receiver, we also discuss the mechanism.

Qigong is a type of meditation originating in Chiena and shares some common features with yoga and zen Buddhism. Our aim was to introduce scientific imaging technology in order to describe this unique state of mind by simultaneous recording of positron emission tomography and EEG. Regional cerebral blood flow (rCBF) images obtained by using [15O] water were transformed onto the Talairach-Tournoux's coordinate using brain standardization techniques. A statistical analysis of regional cross correlation between rCBF and EEG frequency fractions was examined to identify possible brain regions which related to qigong meditation. Eight right-handed normal subjects who served as a control compared with eight qigong professionals. The slow EEG waves (the delta) accompanied a general reduction of rCBF at resting condition and vice versa. The results of the control subjects document the effects of psychological tension or relaxation in rCBF during PET measurements. EEG slow waves in the qigong professionals on the contrary, accompanied increases in rCBF in deep brain structures. The right amygdala correlated with both EEG theta and alpha and the left hippocampus with delta. No remarkable positive correlation was found in the necortices as a whole. These results support that qigong meditation is a state of mind that departs from ordinary thoughts traveling into the depth of consciousness.

The paranormal ability such as PK and ESP of a Japanese boy was examined. The computer employed random number guessing game and electrophorsis experiment suggested that his ability is so called psy-missing one. Biophysical measurement by near-infrared photometry and by a single square voltage pulse method indicated some changes of oxygen metabolism in the brain and sutonomic nerve system at metal bending or clair-voyance.

The Buddhistic meditation (Zazen) is practiced with eyes half closed and prolonged respiration. For the sake of investigating these effects on the brain, forced meditation using a blindfold and with hyperventilation was tried. An analysis using electroencephalograms (EEGs) had the following results. 1) The blind condition produced many α waves over all channels (it means inhibition of brain activities). 2) The lag time of the α waves between the occipital and frontal region (τm) was prolonged by the forced respiration. 3) The frequency of the α wave became lower during hyperventilation. These changes in the α waves seemed to show a superior condition during the deep Zen-meditation. However, the original traces of the EEG at that time frequently showed many slow waves around the δ and θ band, and the subject told of the feeling almost faintish. The strong suppression of the brain seemes to be a dangerous condition.

The objective of the experiment is to verify whether a tohate performed by a master of qi-gong depends on his suggestion or not. When the master performed the tohate for his pupil, with the master and his pupil separately positioned in two rooms, each of which was located on a different floor of a sense-shielded building, the master's acting time and his pupil's response time were recorded. The time differences between the master's acting time and the pupil's response time were one sec and less, 6 times in 16 trials. This result implies that all tohates do not depend on the master's suggestion and unknown transmission of tohate acting, since the same event by chance as the result de-scribed above gives a probability of 0.0058; the value is of sufficient significance on approximate synchronous timing between both performances of some tohates.

Therapeutic efficacy of the external qigong, one of the prevailing popular medicine in the Asian countries including Japan, is evaluated by means of the modern western medical technologies which are supposed to present an objective guide-line for judgement. Furthermore, a mechanism for its efficacy is tried to be explained by the modern western medical order. A total of 30 external qigong therapies was applied in 20 patients with arteriosclerotic obstruction. A therapeutic effectiveness rate was 83.3% for subjective symptoms such as cold leg, leg pain at walking or leg pain at rest, 90.0% for a rise in the leg temperature measured by a thermography, 72.4% for improvement in a plethysmography and 64.7% for improvement in peripheral blood flow by an ultrasonic Doppler flow metry, respectively. These were more favorable than anticipated. However, the mechanism for inducing therapeutic efficacy is absolutely unundersdandable within the modern western medical paradigm.
