A Sitting Tai Chi Programme for Chronic Stroke Survivors With Post-stroke Cognitive Impairment

Introduction Stroke remains the third leading cause of death and disability combined. Post-stroke cognitive impairment (PSCI) is a common neurological sequela that may affect up to 80% of stroke survivors. Several systematic reviews and studies indicated that Tai Chi benefits patients with mild cognitive impairment, leading to significant improvement in cognitive function. Our previous study adopted a tailored sitting Tai Chi programme for the rehabilitation of subacute stroke survivors without any cognitive impairment. The results of the randomised controlled trial (RCT) showed that upper limb function, balance control, ADL, depressive symptoms, and QoL were significantly improved compared to the control group. To better understand the usefulness of the sitting Tai Chi programme for chronic stroke survivors with cognitive impairment and how it might affect other rehabilitation outcomes, this study was proposed to examine its feasibility and preliminary effectiveness. Methods An outcome assessor-blinded RCT will be conducted. Participants will be randomised with a 1:1 allocation ratio to either the intervention group or the waiting list control group. A total number of 88 dyads (176 participants) including 44 stroke survivors and 44 caregivers will be recruited in each group. For the qualitative part, a purposive sample of 30 stroke survivors with low, medium and high satisfaction scores will be invited. Intervention Sitting Tai Chi group: Participants in the sitting Tai Chi group will receive 12 weeks of 10-form sitting Tai Chi exercise training with a frequency of three days a week and 40 minutes a day, including 5 minutes warm-up, 30 minutes Tai Chi training, and 5 minutes cool-down. A registered nurse (RN) with experience with Tai Chi training and who participated in our previous study will lead the training session. The RN will receive refresher training in sitting Tai Chi and learn the basics about the condition of PSCI and the characteristics of survivors
