简要总结
This study evaluates the feasibility and the preliminary effects of a simplified 10-step Tai-chi programme (a dyadic approach) on the mobility performance of people with mild to moderate dementia.
Four community health centres were recruited and each was randomised to either the intervention group (Tai-chi) or the control group. Tai-chi group received a 16-week 10-step simplified Tai-chi training programme in which additional measures were implemented to enhance participants' engagement. The control group took part in group recreational activities organized by the community centres.
It was hypothesized that the Tai-chi group would outperform the control group regarding their mobility performance.
详细描述
Four community health centres that provide dementia care services were recruited through convenience sampling. Each was viewed as one cluster and was randomized to either the Tai-chi or the control group, based on computer-generated random numbers prepared by an independent statistician.
Participants allocated to the Tai-chi group took part in the 16-week 10-step simplified Tai-chi programme, which was derived from the traditional Yang style and has been proven to be effective in enhancing older people's balance and mobility. Each week, the dyads attended two 1-hour sessions of centre-based Tai-chi training and practised at least three 30-minute Tai-chi sessions at home. Additional measures targeted cognitively impaired people were implemented to promote engagement, including the adoption of multiple sensory cues, slow and relaxed practice, a dyadic approach, and positive emotional motivation techniques.
Participants allocated to the control group took part in group recreational activities such as watching movies or listening to music, which was organized by the community centres with similar frequency and duration of the Tai-chi sessions that were organized for the Tai-chi group. The control group participants were instructed to continue their usual lifestyles and levels of physical activity.

研究组 & 干预措施
Tai-chi group
16-week 10-step simplified Tai-chi programme.
Two 1-hour sessions of centre-based Tai-chi training and a minimum of three 30-minute Tai-chi sessions at home on a weekly basis.
干预措施: Tai-chi group (Other)
Control group
Group recreational activities and continue their usual lifestyles and levels of physical activity as usual for 16 weeks.
Two 1-hour sessions of group recreational activities on a weekly basis.
结局指标
主要结局
Recruitment rate
时间窗: Enrollment date
The number of dyads who provided consent to join the study over the eligible dyads
Participants' adherence to practising Tai-chi at home and in the training sessions
时间窗: Throughout the 16-week programme
Exercise adherence (Tai-chi group only) was assessed by both the exercise diaries and training session attendance. Caregivers were instructed to record participants' adherence in terms of the frequency and duration of their Tai-chi home practice in a weekly exercise diary.
Occurrence of adverse events such as falls
时间窗: Throughout the 16-week programme and during the training sessions
Any adverse events at home were recorded.
Attrition rate
时间窗: At the end of the 16-week programme
The attrition rate was indicated by the percentage of dyads withdrawing from the study
次要结局
- Number of steps recorded in the Step Test(Baseline, 8th week and 16th week from baseline)
- Time measured in the Timed-up-and-Go test(Baseline, 8th week and 16th week from baseline)
- Length measured by the Functional Reach test(Baseline, 8th week and 16th week from baseline)
- Menorah Park Engagement Scale(every week of the 16-week Tai-chi programme)
- Time measured in the Timed Chair Stand test(Baseline, 8th week and 16th week from baseline)
- Focus interview groups(17th week from baseline)
