Objectives: To explore whether tai chi and Qigong can improve cognitive function in patients with neurological disorders.
Methods: The PubMed, Embase, Cochrane Central Register of Controlled Trials, SinoMed Database, Chinese National Knowledge Infrastructure (CNKI), Wanfang, and China Science and Technology Journal Database (VIP) databases were searched from inception to December 24, 2021. The methodological quality of the included studies was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions criteria.
Results: This study included 2,754 participants from 40 randomized controlled trials (RCT)s with low to high methodological quality. Analysis of active and non-active comparisons showed significant effects for tai chi/Qigong (P<0.05) on global cognitive function, executive function, memory, visuospatial ability, and cognitive processing speed.
Conclusions: Tai chi and Qigong were effective interventions to improve cognition in patients with Parkinson's disease, stroke, mild cognitive impairment, dementia, and traumatic brain injury; however, no RCTs were performed for other neurological disorders.
