Technology Interventions to Improve Outcomes After Knee Replacement
- Conditions
- Knee Arthroplasty
- Registration Number
- NCT04482400
- Lead Sponsor
- University of South Carolina
- Brief Summary
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 .
- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Change in Objectively Measured (Actigraph) Sedentary Behavior at 5 months 5 months - baseline change in sedentary behavior (\<100 counts/minute) measured with Actigraph accelerometers between baseline and 6 months
Change in Objectively Measured (Actigraph) Sedentary Behavior at 2 months 2 months - baseline change sedentary behavior (\<100 counts/minute) measured with Actigraph accelerometers between baseline and 3 months
- Secondary Outcome Measures
Name Time Method Change in WOMAC Pain Subscale 5 months after surgery WOMAC Pain Subscale - Scores range from 0 (no pain) to 20 (maximal pain)
Total physical activity measured by Actigraph accelerometers 5 months after surgery objectively measured light, moderate and vigorous activity (\>= 100 counts/min) by Actigraph accelerometers
