Objective::
To evaluate the feasibility and preliminary effects of a simplified 10-step Tai-chi programme to improve the motor performance of people with dementia.
Design::
A two-arm, single-blinded cluster randomized controlled trial, registered with ClinicalTrials.gov (NCT03341091).
Setting::
Community health centres.
Participants::
Twenty-six dyads of people with dementia and their family caregivers were recruited, with mean (SD) ages of 82.2 (7.43) and 51.3 (18.97), respectively.
Interventions::
The experimental group underwent a 16 week 10-step simplified Tai-chi training programme, with additional measures to enhance engagement. The control group joined recreational activities organized by the centres.
Main Outcome Measure(S)::
The feasibility assessment included recruitment, attrition, adherence to, and engagement in the Tai-chi programme. The preliminary effects were assessed by the participants' performance in mobility tests.
Results::
Preliminary feasibility was established, with an acceptable recruitment rate of 58% (26 out of 45 assessed dyads) and a high attendance rate of 81% (25.88 out of 32 Tai-chi sessions). There was positive engagement in the training sessions, and no adverse incidents. However, five participants withdrew from the Tai-chi group, for a high attrition rate of 38%, and the mean home practice time decreased between weeks 8 and 16. In most of the motor performance tests, a slight but insignificant improvement was observed in the Tai-chi group compared to the control group.
Conclusion::
A tailored Tai-chi programme for people with dementia using a dyadic approach has been found to be feasible. However, stronger support must be provided to family caregivers to improve the participants' sustained participation.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
