Rehabilitation for Knee Arthritis in Veterans

This study is looking at ways to help Veterans with knee osteoarthritis (KOA), a common type of arthritis, maintain the improvements they get from physical therapy. Researchers are testing two approaches: Health Coaching and a Remote Incentive Program. The Remote Incentive Program uses games, social encouragement, and monitoring to help people stick with their exercises. The main goal is to see if these interventions help people keep up with exercise and physical activity for 6 to 18 months after physical therapy. You might be able to join if you are a Veteran aged 40-90, have knee osteoarthritis, and are starting physical therapy or just had your first session. The study is currently unclear about its recruitment status and plans to enroll 254 participants.

Study design
This is a randomized clinical trial with a factorial design, meaning participants will be randomly assigned to different groups to test the interventions. It plans to enroll 254 participants.
What's involved
Participants will interact with a clinical trial platform on their smartphone to capture important information. The study aims to measure outcomes between 6 and 18 months.
Compensation
Not stated in the trial record.
Follow-up
The study will measure outcomes between 6 and 18 months after the interventions.

What this trial measures

  • KOOS (Knee Osteoarthritis Outcome Score)all available measures between 6-18 months (time-averaged effect)

    The KOOS score is a validated and widely used measure of knee-related pain and physical functioning that has been validated in both knee injury and KOA populations. The KOOS measures symptoms and disability on five subscales: Pain, other Symptoms, Function in Activities of Daily Living, Function in Sports and Recreation, and Quality of Life (QOL). Range is from 0-100 for each subscale with lower scores suggesting worse patient experience.
