Abstract
One of the authors has previously investigated physiological characteristics of practitioners and their clients during various sessions using qigong, meditation and healing and discussed their effects using mainly EEG analyses. In this report, the authors studied differences in muscle activities between qigong/taichi-quan and stretch/gymnastic exercises and discussed similarities and differences in the conscious states expressed in the EEGs while doing those practices. Neural activities which cause the muscle motion appear as extremely small peaks on the transient EEG chart and are too difficult to measure directly. However, the low frequency parts of EMGs induced by the motion are mixed into the β bands of the EEGs. So, it is possible to estimate muscle activities from the rates of each frequency band of the EEG. The higher-level practitioners were considered to perform qigong or taichi-quan with the less work by the muscles. During meditation, the authors observed that the α waves increased on the frontal area of the brain and sometimes the θ waves also increased. The EEGs during ThetaHealing®, introduced recently from the USA, were compared with those during qigong and meditation. The θ waves occasionally appeared, as they did in the meditation state. Those conscious states were considered to lead to the healing effects.
