An Implementation Science Approach to Evaluating Self-Administered Acupressure for Knee Osteoarthritis in Older Adults in the Community

What this Trial Is About

Researchers are evaluating the use of a self-administered acupressure (SAA) program to manage knee osteoarthritis (OA) in older adults aged 60 and above in Hong Kong community centers. This pragmatic cluster randomized controlled trial aims to study how well the program is adopted, implemented, and maintained in real-world settings, and to assess its effectiveness in reducing knee pain, improving function, and enhancing quality of life. The study uses a mixed-methods approach, including qualitative interviews to explore the experiences of participants and service providers. Participants are divided into two groups: one receives the SAA program involving two 2-hour training sessions spaced one week apart, including acupressure techniques, knee health education, and practice with feedback. They are asked to perform acupressure at home twice daily for 24 weeks, with ongoing support through phone calls and messaging apps. The control group receives a general health education booklet and instructions to read it at home. After 24 weeks, the control group will also be offered the SAA program. During the study, participants undergo assessments at baseline and at weeks 4, 12, and 24, measuring knee pain severity using a numerical rating scale, knee function with the WOMAC index, quality of life with SF-6D, and physical function tests like Timed Up and Go and Fast Gait Speed. Researchers will monitor adherence, analgesic use, and implementation success through the RE-AIM framework. Data analysis includes quantitative comparisons and thematic analysis of interviews to understand facilitators and barriers. The total participation time spans 24 weeks with regular follow-ups.
