Video Games may Improve Physical Therapy Outcomes

Guess and the team of researchers used the depth camera from a video game system to capture movement from participants doing drop vertical jumps and lateral leg raises. The participants' movements also were measured using traditional motion-capture technology that involved placing markers on their skin. Researchers found that the systems produced similar results.

The recent findings on how video game technology can improve physical therapy are a result of a multi-disciplinary collaboration at MU started by Aaron Gray, a sports medicine physician with MU Health Care. Gray was interested in how easily accessible technology could help athletes avoid knee injuries. He began working with a team of researchers to test the idea, including Guess; Marjorie Skubic, professor of electrical engineering and computer science; Brad Willis, assistant teaching professor of physical therapy; and David Echelmeyer, physical therapist with the Missouri Orthopaedic Institute; and Seth Sherman, associate professor of orthopaedics.

"Assessment of movement is essential to evaluating injury risk, rehabilitative outcomes and sport performance," Gray said. "Our research team is working to bring motion analysis testing--which is expensive and time consuming--into orthopaedics offices, physical therapy clinics and athletic facilities using inexpensive and portable technology. Our research has shown that depth camera sensors from video games provide a valid option for motion assessment."

The researchers recently had several studies on the technology published, including "Comparison of 3D joint angles measured with the Kinect 2.0 skeletal tracker versus a marker-based motion capture system," in the Journal of Applied Biomechanics and "Development and validation of a portable and inexpensive tool to measure the drop vertical jump using the Microsoft Kinect V2," in Sports Health.
