Although in its current state modern science cannot directly measure/detect Qi, it is still possible to study the effects of Qi or more specifically, study the effects of the understanding of human body according Traditional Chinese Medicine based on outcomes from treatments and experiments. Below is a list (and Links provided) of Scientific studies of Traditional Chinese Medicine, Qi, Qigong and Tai chi.
• Evidence and Mechanism of External Qi in Chinese Medicine (https://www.liebertpub.com/doi/10.1089/acu.2007.0524)
o The patient reported continuous and steady improvement in the 3-month period. Significant changes in the maximum temperature were observed at some parts of the body before and after each healing session. The temperature of the body parts stabilised.
• Effects of Qi-therapy on blood pressure, pain and psychological symptoms in the elderly: a randomized controlled pilot trial (https://www.sciencedirect.com/science/article/abs/pii/S0965229903000888)
o The Qi-therapy group exhibited greater reduction in anxiety, depression, fatigue, pain level and blood pressure compared to the placebo group; the difference in anxiety was significant.
• The scientific hypothesis of an “energy system” in the human body (https://www.sciencedirect.com/science/article/pii/S2095754818300358)
o This paper discusses the importance of exploring the knowledge of the human body according to TCM knowledge because coupled with Modern medicine this will lead to a more complete understanding of the human body
• Evidence of Qi-gong Energy and its Biological Effect on the Enhancement of the Phagocytic Activity of Human Polymorphonuclear Leukocyte (https://www.worldscientific.com/doi/pdf/10.1142/S0192415X01000022?download=true)
o The results of this study were “significant statistically, and this phenomenon was highly reproducible”. A chemical solution in a bottle was influenced to alter its chemical activity by a Qigong Master Healer.
• A Comprehensive Review of Health Benefits of Qigong and Tai Chi (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3085832/?fbclid=IwAR19-vjeRLggVIFvrQgBiIaV20x9_kf01PCjmZfwt_DV53T7sEmn6dNhGzQ)
o Seventy-seven articles met the inclusion criteria. The 9 outcome category groupings that emerged were: bone density (n=4), cardiopulmonary effects (n=19), physical function (n=16), falls and related risk factors (n=23), Quality of Life (n=17), self-efficacy (n=8), patient reported outcomes (n=13), psychological symptoms (n=27), and immune function (n=6).
o Research has demonstrated consistent, significant results for a number of health benefits, evidencing progress toward recognizing the similarity and equivalence of Qigong and Tai Chi
