Evaluation Study for the "Jockey Club E-Generation: Impact Extension Project for Chronic Knee Pain Management"

Overview

Objectives: This study aims to evaluate the effectiveness of the "Jockey Club E-Generation: Impact Extension Project for Chronic Knee Pain Management", with a view to developing sustainable strategies of self-management on chronic conditions integrating with tele-rehabilitation technology. Study design and participants: An evaluation study adopting a randomized controlled trial design, with waitlist attention control will be conducted in Elderly community centres of Hong Kong Sheng Kung Hui Welfare Council and Christian Family Service Centre (CFSC) in Hong Kong. The proposed sample size is 858 participants, which is a convenience sample from the service user of the "Jockey Club E-Generation: Impact Extension Project for Chronic Knee Pain Management". At least 15 participants will be invited for qualitative interview. Participants will be randomized to the intervention group or the waitlist attention control group in 1:1 ratio using block randomization with random block size of 4, 6 and 8, stratified by each centre and severity of condition. A researcher independent to the project will generate the randomization sequence by computer and keep the list. Participants in the intervention group (known as Group A to the participants) will start the 12-week intervention immediately, whereas the waitlist attention control (know as Group B to the participants) will start the intervention after 12 weeks. During the waiting period, waitlist control receives attention control. Measurements: The primary outcome of this study is quality of life. It will be measured by the Hong Kong Chinese version of World Health Organization Quality-of-Life Scale (WHOQOL-BREF). The secondary outcomes are pain, physical functioning, emotional functioning, adherence rate, satisfaction score, rate of adverse events in relation to the intervention, and cost-effectiveness of the intervention. Expected results: The improvement in health-related quality of life of older adults is larger in the intervention group as compared to the control group; The relief in knee pain of older adults is larger in the intervention group as compared to the control group; The improvement in physical functioning of older adults is larger in the intervention group as compared to the control group; The improvement in emotional functioning of older adults is larger in the intervention group as compared to the control group.

Interventions

• Other 12-week intervention
  Rehabilitation Exercise Plan Week 1-4 For No Symptom Group: Therapeutic home exercise prescription(2 sessions, 60 minutes per session) For Mild \& Moderate Group: Rehabilitation Plan provided by Physiotherapist (4 sessions, 60 minutes per session) Enhancement of Self-Management Capacity Week 5-8 For No Symptom Group: Educational Workshops provided by Physiotherapist (2 sessions, 60 minutes per session) For Mild \& Moderate Group: Self-management group provided by Social Worker (4 sessions, 60 m
• Other 12-week attention control
  The attention and waitlist control group will have weekly educational and virtual workshops for 12 weeks. Three topics will be covered, including online exercise class, cognitive training, leisure and recreational activities. Each session will be 30-45 minutes and each topic last for four weeks. Participants could access the virtual sessions by their electronic devices.
