Abstract
Abstract Introduction We investigated the effect of Tai Chi exercise on postural balance among people with dementia (PWD), and the feasibility of a definitive trial on falls prevention. Method We conducted a randomised controlled trial. Dyads, comprising community-dwelling PWD and their informal carer (N=85), were randomised to usual care (n=43) or usual care plus the intervention (n=42). For the intervention, over 20 weeks, Tai Chi classes were provided weekly and Tai Chi home practice was facilitated by the carer. The primary outcome was the timed up and go test. Secondary outcomes for PWD included functional balance, static balance, fear of falling, cognitive functioning, quality of life, and falls. Secondary outcomes for carers included dynamic balance, static balance, quality of life, and carer burden. Outcomes were assessed six months post-baseline, except for falls, which were collected prospectively over the six-month follow-up period. Results For PWD, there was no significant difference at follow-up on the timed up and go test (mean difference [MD] = 0.82, 95% confidence interval [CI] = -2.17, 3.81, standardised effect size [ES] = 0.14). Among the secondary outcomes, at follow-up, PWD in the Tai Chi group had significantly higher quality of life (MD = 0.051, 95% CI = 0.002, 0.100, ES = 0.51) and a significantly lower rate of falls (rate ratio = 0.35, 95% CI =0.15, 0.81), which was no longer significant when an outlier was removed. Carers in the Tai Chi group at follow-up were significantly worse on the timed up and go test (MD = 1.83, 95% CI = 0.12, 3.53, ES = 0.61). The remaining secondary outcomes were not significant. No serious adverse events were related to participation in Tai Chi. Conclusion With refinement, this Tai Chi intervention has potential to reduce the incidence of falls and improve quality of life among community-dwelling PWD.
Highlights
Falls are a major public health issue among older people.[1]
We report the first randomised controlled trial to test if Tai Chi can improve postural balance among people with dementia (PWD), and the future definitive trial will be the first to test if Tai Chi can prevent falls among PWD
The exceptions were that refreshments were not always provided to encourage socialising after classes, when classes finished late in the afternoon or where parking was restricted
Summary
There is robust evidence for interventions, and in particular exercise-based interventions, to prevent falls and fall-related injuries among community-dwelling people without cognitive impairment.[6,7,8] to date, only three exercise trials have been conducted with community-dwelling PWD,[9,10,11] of which only one reported outcomes up to a 12-month follow-up.[9] This latter study used an intensive provision that may be too expensive for some health services, including the UK. There is a need for more evidence-based fall prevention interventions for PWD
