Technology Interventions to Improve Outcomes After Knee Replacement

University of South Carolina83 enrolled

Overview

The purpose of this study is to examine the effects of two technology interventions on health outcomes (e.g., physical activity, sedentary behavior, physical function, pain) after knee replacement at 2 and 5 months .

Two 8 week technology interventions will be examined and consist of the use of an app and/or website and regular calls. Assessments to examine outcomes will be completed at baseline, as well as at 2 and 5 months.
