The Energize! Study for Adults With Knee Replacement

Study Overview
=================
Brief Summary
-----------------
The purpose is to examine the effects of an online physical activity program on moderate to vigorous intensity physical activity, pain, and physical function in adults with knee replacement at 3 months (post-intervention) and 6 months (maintenance).

Detailed Description
-----------------
Participants with knee replacement will be randomized to start the online physical activity program (Energize!) either immediately or after 3 months. The online program consists of weekly physical activity goals, video lessons, action planning, and homework to help increase physical activity to 200 min/week. Assessments will be completed at baseline, 3 months, and 6 months.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Minutes of moderate to vigorous intensity physical activity | activity assessed by Actigraph accelerometers | baseline to 3 months | 
| Pain intensity | Pain intensity assessed by Patient-Reported Outcomes Measurement Information System pain intensity survey. 0 represents no pain and 10 reports the most severe pain | baseline to 3 months | 
| Self-reported physical function | Physical function assessed by Patient-Reported Outcomes Measurement Information System physical function/mobility survey. A t-score of 0 represents poor function compared to average and 100 represents better function. | baseline to 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Minutes of moderate to vigorous intensity physical activity | activity assessed by Actigraph accelerometers | 3 months to 6 months | 
| Pain intensity | Pain intensity assessed by Patient-Reported Outcomes Measurement Information System pain intensity survey. 0 represents no pain and 10 reports the most severe pain | 3 months to 6 months | 
| Self-reported physical function | Physical function assessed by Patient-Reported Outcomes Measurement Information System physical function/mobility survey. A t-score of 0 represents poor function compared to average and 100 represents better function. | 3 months to 6 months |
