Purpose: Age-related cognitive decline is a growing public health concern worldwide. More than a quarter of adults with cognitive impairment experience sleep disturbance. The objective of this pilot study was to evaluate the preliminary effects of tai chi qigong (TCQ) on improving the night-time sleep quality of older adults with cognitive impairment.
Participants: Older adults with cognitive impairment who complain of sleep disturbance.
Methods: A randomized controlled trial with two groups. Fifty-two subjects were recruited from two district elderly community centers and randomly assigned to either the TCQ group (n=27) or the control group (n=25). The intervention group received TCQ training consisting of two 60-minute sessions each week for 2 months. The control group was advised to maintain their usual activities. Sleep quality was measured by the Chinese Pittsburgh Sleep Quality Index. Quality of life was measured by Short-form 12, cognitive functions measured by mini-mental state examination, and subjective memory deficits measured by the memory inventory for Chinese.
Results: Data were collected at baseline, 2 months, and 6 months. Significant results were noted at 6 months in the Chinese Pittsburgh Sleep Quality Index global score (P=0.004), sleep duration (P=0.003), habitual sleep efficiency (P=0.002), and the Short-form 12 mental health component (P<0.001). The TCQ participants reported better sleep quality and a better (quality of life) mental health component than the control group.
Conclusion: TCQ can be considered a useful nonpharmacological approach for improving sleep quality in older adults with cognitive impairment.Clinical trial registration: CUHK_CCT00448 (https://www2.ccrb.cuhk.edu.hk/registry/public/287).
