Exercise Adherence Among Older Adults With Osteoarthritis

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to assess the comparative effects of two different ways of enhancing long-term adherence to and benefits associated with participation in the evidence-based, Fit and Strong multi-component exercise intervention for older persons with lower extremity osteoarthritis.

Clinical Trial Description

Osteoarthritis (OA) is the most common condition affecting older people today. It is the leading cause of disability among older people and its impact is projected to increase substantially with the aging of the U.S population from 43 million currently to 60 million by 2020.

Promising 2- and 6-month outcomes have recently been reported from a randomized trial of a multi-component exercise intervention targeted at older adults with lower extremity OA. The Fit and Strong intervention, developed and tested as part of the Midwest Roybal Center for Health Maintenance, coupled strength training and aerobic walking with health education for sustained behavior change. Improvements have been found in confidence in ability to exercise, confidence in ability to continue exercising over time, lower extremity stiffness, lower extremity pain, and 6-minute distance walk. Importantly, the average adherence rate in the people who participated in the exercise intervention at six months was twice that reported by controls.

The specific aims of this study are to use a multi-site randomized controlled clinical trial to replicate the Fit and Strong intervention and to test the comparative effectiveness of a negotiated/tailored follow-up maintenance strategy vs. a mainstreaming, facility-based maintenance strategy, both of which will be tested with and without telephone reinforcement as an enhancement.

All enrolled participants will participate in the 8-week Fit and Strong exercise program designed specifically for older adults with lower-extremity OA. Prior to the conclusion of Fit and Strong participants will be randomly assigned to one of two follow-up maintenance groups. There is no more than minimal risk associated with this program. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
