New technologies to Measure Change in Daily Activities after Physical Therapy for Knee Osteoarthritis

Research Center: Boston University
Location: 635 Commonwealth Avenue, Boston, MA 02215
Lead Researchers: Deepak Kumar, PT, PhD and Tuhina Neogi, MD, PhD
IRB Committee: This study has been reviewed and approved by Boston University Institutional Review Board


Knee osteoarthritis (OA) is a very common and painful condition among adults aged 50 and up. Exercise-based physical therapy has been the most effective treatment for people with knee OA. However, it has been challenging for physicians to accurately measure the improvements in daily function after physical therapy while the patients are at home or in the community.

The goal of this study is to develop wearable sensor technologies that could measure change in daily function (physical activity, movement patterns, etc.) after exercise-based physical therapy in people with knee OA. Wearable sensors mean small, lightweight devices that can be worn on the body (e.g., Fitbit, pedometer, etc.). Information gathered could then be used to help develop more effective therapies for adults with knee OA.

This study seeks adults aged 50 years old and older who are diagnosed with knee osteoarthritis. Participants are required to attend 4 study visits at the research site and 18 physical therapy treatment sessions  over 4-5 months. Of the 18 physical therapy sessions, 10 will be at the Boston University Physical Therapy Center and 8 will be at home (using video call). Participants will receive a tablet computer as part of the study that does not have to be returned at the end. Participants may receive up to $435 for participating in this study.
