Hello, my name is George Picard. I am a fourth Generation Qigong/Taiji Master in the linage of Grand Master Dr. Wang Zi-Ping. He developed a system of 20 posture Therapeutic Qigong for healing disease and prolonging life. I have been teaching and certifying instructors for 18 years . I teach this system through D'Youville college, Buffalo NY. as an online credit course for PT's, OT's and other health care professionals. I have a medical board and research team. all part of The Village of Healing and Wellness. I would suggest this system for your back issue due to the fact that many students with serious back problems have achieved success eliminating pain, getting off medication and experience a high quality of life. We have recently published a paper on this topic. this is a case study that may help you. Here is the link; http://www.mdpi.com/2305-6320/5/3/60/htm
