“…An extension trial involving the addition of further instruction in qigong (forms of meditation) further supports the observation that benefits are related to the amount of practice [ 27 ]. Qualitative information from an RCT (qigong for 6 months) [ 29 ], and the extension trial (qigong ≥ 12 months) [ 27 ], indicates that, in addition to positive comments on core domains that essentially recapitulate the quantitative information (pain, sleep, impact, physical and mental function), health benefits in other areas also are reported (e.g., food allergies, chemical sensitivities, asthma, sleep apnea, migraines, and blood pressure). In those who practiced qigong extensively via involvement in community-based venues (1–3 years), marked health benefits occurred in FM symptomology (pain absent or minimal; other core domains improved), and there were additional benefits (e.g., irritable bowels, food sensitivities, headaches, blood pressure, and skin) [ 28 ].…”
