..exploring the effects of chair yoga (CY), compared to music intervention (MI) and chair-based exercise (CBE) in this population. Using a cluster randomized controlled trial (RCT), 3 community sites were randomly assigned 1:1:1 to CY, MI, or CBE. Participants attended twice-weekly 45-minute sessions for 12 weeks..
The CY group improved significantly in quality of life compared to the MI group .. However, no significant group differences were observed in physical function, behavioral, or psychological symptoms (eg, for mini-PPT: slopetime = 0.01, standard error [SE] = 0.3, P = .984 in the CBE group; slopetime = −0.1, SE = 0.3, P = .869 in the MI group; slopetime = −0.3, SE = 0.3, P = .361 in the CY group) over the 12-week intervention period.
Overall, this pilot study is notable as the first cluster RCT of a range of nonpharmacological interventions to examine the feasibility of such interventions in older adults, most with moderate-to-severe dementia. Future clinical trials should be conducted to examine the effects of nonpharmacological interventions for older adults with dementia on health outcomes.
