An interventional study of Dual-task training and Attention Control in Aging Well, sponsored by The University of Hong Kong. Completed at 1 site in Hong Kong. Open to participants aged 65 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-08-23.
Sponsored by The University of Hong Kong · Not applicable, Interventional, and Prevention
Objectives: This study aims to explore the feasibility, acceptance, and efficacy of online group-based dual-task training as an intervention for improving cognitive function among community-dwelling older adults.
Hypothesis to be tested: We hypothesize that after the intervention, there will be an improvement in the participants' cognitive function as compared with pre-intervention status and with the control group. Also, lower-limb muscle strength and psychosocial wellbeing will be improved after the intervention.
Design and subjects: This is a randomised controlled feasibility study. The target population is community-dwelling older adults with access to an online meeting platform. About 75 participants will be recruited and randomised to the intervention and attention control groups in a ratio of 2:1. Intervention group will receive 60 minutes of online group-based dual-task training twice a week for 12 weeks led by a trained facilitator. Cognitive training components include arithmetic operation, verbal fluency, and upper limb/finger movement. Physical training components are chair-based exercises. The training components will be selected using a co-design approach.
Instruments: Memory Inventory in Chinese (MIC), Digit Span Test, Victoria Stroop Test, Montreal Cognitive Assessment 5-Minutes (Hong Kong Version).
Main outcome measures: Subjective memory complaints as measured by MIC.

Participants will receive a one-hour online group-based dual-task training session twice a week for 12 weeks, giving a total intervention time of 24 hours. A co-design approach will be adopted to develop the training components in the dual-tasks. For the cognitive training component, arithmetic operation, verbal fluency, and upper limb/ finger movements are included. For the physical training component, we select chair-based exercises are included. A group-based training mode led by a facilitator will be adopted. During the session, participants will be asked to turn on their camera so that they can see and interact with each other. They will also have their audio on as they will have to participate in the cognitive tasks by voicing out their answers.
Participants will receive eight one-hour online group-based interactive education on health topics other than exercise and cognitive health.
Change from baseline subjective memory complaints at 6 weeks
Measured by Memory Inventory in Chinese. The sum of score ranges from 0 to 108, higher score indicates more memory complaints.
