Status Recruiting

Clinical Trial Summary

Evidence supports that dual-task training reduces fall risk among older adults. However, the current framework for preventive care for fall prevention in Hong Kong does not include formal cognitive training, while little to no emphasis is placed on combining physical and cognitive training (dual tasking) to prevent falls. Secondly, the healthcare costs for eligible Hong Kong citizens are subsidised by between 81 and 97% of the actual treatment cost. Therefore, there is a demanding need for cost-effective treatment to reduce the country's' economic burden. This project will assist policymakers and clinicians in recommending cost-effective treatments for fall prevention.

Clinical Trial Description

Objective: Evaluate the effectiveness and cost-effectiveness of self-administered dual-task training (sDTT) for preventing falls among older adults and promote this technique to the target population and healthcare workers of Hong Kong.

Design: In Phase 1, a multi-centre randomised controlled trial (RCT) with economic evaluation will evaluate the effectiveness and cost-effectiveness. In Phase 2, the technique will be promoted through hands-on workshops for older adults and helpers; and promotional talks with physiotherapists and rehabilitation nurses.

Setting: Community-based elderly care centres. Participants: For the RCT, we will recruit 190 community-dwelling older (≥65 years) adults of both genders having experienced at least one fall in the past 6 months. 500 community-dwelling older adults will be recruited for the workshop and 100 healthcare workers will be engaged for promotion activities.

Intervention: In Phase 1, the experimental group will receive sDTT from a physiotherapist once every 2 weeks for 12 weeks. They will perform home exercises once per week for 12 weeks. Unsupervised exercises will then continue over the next 6 months. Control group will receive the same amount of self-administered single-task training as the experimental group.

Primary outcome measure: Number of falls will be assessed at baseline (T1), post-intervention after 12 weeks (T2) and 6 months (T3). Health promotion will be assessed using a knowledge and attitude questionnaire.

Analysis: General linear mixed model with maximum likelihood estimation will compare primary and secondary outcome measures. Cost-effectiveness will be assessed from the Hong Kong healthcare perspective. Wilcoxon Signed-Rank test will assess the benefits of health promotion. ;
