Exercise Plus Activity Strategy Training for Osteoarthritis

Study Overview
=================
Brief Summary
-----------------
Purpose: To study the effects of two different rehabilitation programs for people with osteoarthritis of the hip or knee. Hypothesis 1: Participants who received Activity Stratgey Training will report less pain and physical disability at 8-weeks and 6-months follow-up. Hypothesis 2: Participants who receive Activity Strategy Training will have a greater increase in physical activity as measured by a wrist-worn accelerometer. Hypothesis 3: Participants who receive Activity Stratgey Training will report greater improvements in health-related quality of life.

Detailed Description
-----------------
We are testing the effectiveness of a targeted intervention for older adults with hip and/or knee osteoarthritis (LE-OA) using an occupational therapy treatment approach to promote activity engagement. We believe that it is necessary to tailor this intervention to the specific needs of older adults with LE-OA. Based on the literature, exercise is a necessary component of an intervention for older adults with LE-OA. However, this should also be coupled with an Activity Strategy Training (AST) component designed to promote lifestyle changes and thus more lasting effects. The AST component is based on occupational therapy principles and will include behavioral and environmental strategies to increase activity engagement.

Design Details

Primary Purpose: Supportive Care
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: 1<br>Exercise + Education: Eight group sessions (8-15 people) during which participants engage in muscular strength and flexibility exercises. In addition, weekly educational lectures on topics germane to osteoarthritis management are included. | Behavioral: Education<br>* The health education program is based on educational materials from the Arthritis Foundation.<br>|
| Experimental: 2<br>Exercise + Activity Strategy Training: 7/8 sessions will be in a group format in which participants engage in muscular strength & flexibility exercises and listen to education lessons on management strategies for osteoarthritis. The remaining session includes a home assessment by an occupational therapist to facilitate adequate participation in daily living and leisure activities. | Behavioral: Activity Strategy Training<br>* The AST component will involve training in specific behavioral and environmental strategies to facilitate performance in daily activities and routines. The activity strategy training group sessions will use education, group discussion, and demonstration and practice of techniques to facilitate activity performance. Homework assignments will be given after many of the sessions to practice and reinforce concepts learned.<br>|
