Objective To explore the effect of practicing Chinese gymnastic Qigong-Yijinjing on the infrared radiant track along meridian course (IRRTM)of Ren Meridian stimulated by moxibustion on CV-8 among dysmenorrhea patients.Methods Twenty dysmenorrhea undergraduate patients were recruied and practiced Chinese gymnastic Qigong-Yijinjing for 3 months.The numbers of patients of mild,moderate and severe symptoms were collected before and after the intervention.The effects of IRRTM stimulated by moxibustion on CV-8 were compared before and after practicing Chinese Gymnastic Qigong-Yijinjing.Results After practicing Chinese Gymnastic Qigong-Yijinjing,symptoms of 15 patients (including 11 with moderate dysmenorrhea and 4 with severe dysmenorrheal)were relieved to different extent.After the practice,all IRRTM of Ren Meridian turn to be more continuous,clear and regular either the Ren Meridian was stimulated with moxibustion or not.The average surface temperature along Ren Meridian rose significantly after the practicing.The conduction time to achieve the best states of IRRTM along Ren Meridian significantly shortened compared to before the intervention.Conclusion Chinese Gymnastic Qigong-Yijinjing can effectively enhance the transmission of IRRTM along Ren Meridian on dysmenorrhea patients,and may have a positive effect on dysmenorrhea treatment.
