The levels of stress-related hormones in the blood were measured before and after doing Qi Gong health-maintenance exercises, and a control group of walkers with a similar level of movement selected for the basis of a comparative study. The adrenaline, noradrenaline and growth hormone responses of the Qi Gong group were compared with the pre-exercise values. Although no significant difference was observed immediately after exercise, there was a significant drop in all values 30 minutes after exercising. Similar changes in the blood cortisol were noted in the Qi Gong group and walker group. Compared with the pre-exercise value, both group exhibited significant reduction in blood cortisol both immediately following exercise and 30 minutes after exercise, with the lowest value occurring 30 minutes after exercise. In contrast to the increase in stress-related hormones typical after light exercise that was seen in the walker group, the significant reduction response seen in the stress-related hormones of the Qi Gong group with the similar amount of movement was seen as unusual. This suggested that Qi Gong may be a positive means of stress-reduction and a useful health-maintenance method in today's stressful society.
The relationship between coldness of the hands and feet (“Hiesho”) and Blood Stagnation (“Oketsu”), a disorder description unique to Oriental Medicine, was examined using the Oketsu score of five Hiesho cases based on the Terasawa Oketsu Diagnostic Criteria. The effects of acupuncture treatment were studied by evaluating Oketsu symptoms and accompanying complaints, the Visual Analogue Scale (VAS) and subjective evaluation of coldness of the hands and feet. The results were as follows: 1) 100% of the five females with Hiesho were also positive for the Oketsu factor. 2) The Oketsu score showed a significant decrease (P<0.05) upon treatment with acupuncture. 3) An improvement in subjective Hiesho symptoms (VAS) was seen in three of the five cases upon acupuncture treatment. 4) It was suggested that the subjective improvement in Hiesho symptoms, i. e., coldness of the hands and feet, was related to the disappearance of the resistance and pain upon pressure in the ileocecal region that is characteristic of Oketsu, and the improvement in menstrual disorders.
