Abstract

This study assessed the feasibility of conducting 3 nonpharmacological interventions with older adults in dementia, 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. Thirty-one participants were enrolled; 27 safely completed the interventions and final data collection (retention rate of 87%). Linear mixed modeling was performed to examine baseline and longitudinal group differences. The CY group improved significantly in quality of life compared to the MI group (CY mean = 35.6, standard deviation [SD] = 3.8; MI mean = 29.9, SD = 5.3, P =.010). 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.
