Description détaillée
The proposed study is a single-blind randomised controlled trial for two years. We will compare the efficacy of a home-based structured exercise programme (12-step sitting Tai Chi) for both carers and care recipients with a standard non-exercise social contact control in the treatment of depression among caregivers of persons with dementia. The study hypotheses include:
- The structured home-based exercise programme will reduce caregiver depression. (Primary outcome)
- The home-based exercise will improve caregivers' cognitive performance, quality of life and balance ability at the end of the study. (Secondary outcome)
- The home-based exercise will improve the cognitive performance, quality of life and balance ability of persons with dementia at the end of the study. (Secondary outcome)
- We also hypothesise that BDNF gene modulates mood changes in response to exercise intervention. (Secondary outcome)

Intervention / Traitement |
|---|---|
|
Comparateur actif: 12-step sitting Tai Chi Chuan
The intervention is a simplified Tai Chi Chuan exercise, which consists of 12 steps, including weight shifting in different sitting positions, trunk and upper limb movements, and alternate thigh lift in a smooth and coordinated manner.
|
The intervention consists of eight home-based sessions on 12-step sitting Tai Chi Chuan.
Each session will last for an hour.
|
|
Comparateur placebo: Control
We provide participants in the control group with a level of social contact equivalent to the intervention group, which comprises structured conversations on topic other than physical activity.
|
The control consists of eight home-based sessions on useful health-care information.
Each session will last for an hour.

HAM-D-17 is a widely used and reliable measure of depressive symptoms.
The scores range from 0 to 52, with higher scores indicating greater depression severity.
Response to intervention is defined as a reduction of HAM-D-17 total score by ≥50% from baseline to endpoint.
