Remote Tai Chi for Knee Osteoarthritis

Not Applicable

Recruiting

• Conditions: Knee Osteoarthritis
• Interventions: Other: Remote Tai Chi

• Registration Number: NCT06384898
• Lead Sponsor: Tufts Medical Center

Brief Summary

The goal of this pragmatic randomized trial is to evaluate the effectiveness of remote Tai Chi to treat knee pain in adults with knee osteoarthritis. The main questions the trial aims to answer are:

* Compared to routine care, will patients with Knee OA receiving remote Tai Chi exhibit greater improvement in knee-related pain (WOMAC pain score, primary outcome), pain interference (PROMIS-Pain Interference, secondary outcome), and health-related quality of life at 3 months?

* Does remote tai chi decreases healthcare utilization and analgesic use over the one-year study period?

Researchers will compare remote Tai Chi added to routine care to routine care alone to see if remote tai chi works to treat knee osteoarthritis pain. Participants will participate in remotely delivered web-based tai chi sessions, twice a week for 12 weeks, or will continue to receive routine care. Participants will be followed for 12 months after randomization.

Detailed Description

Investigators will conduct a 12-month embedded, pragmatic, hybrid type 1 effectiveness-implementation, individually randomized group-treatment trial that will compare the effects of a 3-month twice weekly remotely delivered web-based Tai Chi intervention plus routine care versus routine care alone across four health care systems (Tufts Medical Center, Boston Medical Center, University of California Los Angeles Health, and Cleveland Clinic) in four geographic regions (Eastern Massachusetts, Southern California, Northeast Ohio (Cleveland Clinic), Southern Florida (Cleveland Clinic). Investigators will enroll a total of 480 diverse patients with a clinical diagnosis of Knee OA. Participants will be evaluated at baseline and 3 months, with additional follow-up at 6 and 12 months.

Arm && Interventions

Group	Intervention	Description
Tai Chi + Routine Care	Remote Tai Chi	The intervention will be delivered via a HIPAA-secure web-based video platform. All remote Tai Chi sessions will be 60 minutes, twice a week, for 3 months. All program components will use the Yang style Tai Chi, and every session will include warm up, review of principles, meditation with movement, breathing techniques and relaxation.

Primary Outcome Measures

Name	Time	Method
WOMAC Pain Score	3 months from randomization	Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score rated on a Visual Analog Scale (VAS) of 0-100 mm.

Secondary Outcome Measures

Name	Time	Method
PROMIS Pain Interference score	3 months from randomization	The PROMIS Pain Interference short form 6b evaluates the extent to which pain interferes with physical, emotional and social activities. The raw score ranges between 6-30 and the T score ranges between 41.0-78.3, with higher scores indicating that pain has a greater negative impact.
SF-12 PCS score	3 months from randomization	The 12-item Short Form Health Survey (SF-12) has two summary scales, the Mental Health Component Score (MCS) and the Physical Component Score (PCS). Both scores range from 0 to 100, with higher scores indicating better mental and physical health.
Number of knee joint injections	12 months from randomization	Total number of intra-articular injections identified through EHR and patient questionnaires.
