2 Agenda Project Origin/Goal Microsoft Kinect Vail Sport Test (VST) Development Environment System Video Demo Summary © Computer Science Department, Texas Christian University

3 Origin of Project Wanted a project that utilized the Microsoft Kinect. Sought to contribute to the healthcare industry. Therapists were interested in validating the grading of the Vail Sport Test. Currently use an expensive and complex system. Post analysis. Charges patients extra for the service. Requires patients to wear markers. Group proposed utilizing the Kinect to develop a cheaper, simpler system. Allows real-time, automatic test analysis. No markers. © Computer Science Department, Texas Christian University

4 Project Goal Objectively score the Vail Sport Test using the Kinect. Provide tool to validate the grading of the Vail Sport Test in the Physical Therapy field. Create an inexpensive, user friendly, and easily deployable system. © Computer Science Department, Texas Christian University

5 Microsoft Kinect Interfaces with a Windows PC. Joint data is presented as (X,Y,Z) coordinates. Ability to track 20 joints on the human body. Limitation: can only capture data 30 times a second. © Computer Science Department, Texas Christian University

6 Vail Sport Test (VST) Used to assess Anterior Cruciate Ligament (ACL) injuries, as well as other leg injuries. Allows therapists to determine if an athlete can return to sport or not. Consists of 4 components, each designed to put stress on the injured leg. Currently subjectively graded. Grading not used by all physical therapists. © Computer Science Department, Texas Christian University

7 Kinect Hip Adjustment Kinect measures the hip joint at the Anterior Superior Iliac Spine (ASIS). Physical therapists use the Greater Trochanter to measure the knee flexion angle. Distance from Iliac Crest to Greater Trochanter, is the Y offset. Distance from Iliac Crest to ASIS, is the Z offset. Offsets are stored in the database for each new patient prior to testing. © Computer Science Department, Texas Christian University

8 Components of VST Single Leg Squat 3 minutes, max of 15 points. 5 points for each minute interval. Lateral Bounding 90 seconds, max of 15 points. 5 points for each 30 second interval. Forward Jogging 2 minutes, max of 12 points. 6 points for each minute interval. Backward Jogging 2 minutes, max of 12 points. 6 points for each minute interval. © Computer Science Department, Texas Christian University

9 Scoring Based on criteria provided by therapist Dr. Craig Garrison. Knee angle Between 30° and 60° Knee lock Must avoid knee lock during extension. Knee Valgus Knee position in relation to foot and hip. Trunk angle Forward, backward, left, and right. Landing position and duration Must be inside bounds and cant stay landed longer that 1 second Extension of patella Patient must avoid patella passing the toe. If a patient fails any of these standards 3 consecutive times, no point is awarded for that standard of the current minute of the component. The patient must score 46/54 points to pass. © Computer Science Department, Texas Christian University

15 Results & Moving Forward Provides real-time, accurate feedback to the patients. Program can judge all standards at once. Difficult for a therapist to watch all standards at once. Patient benefits from improved accuracy in test administration. Able to accurately measure joint angles within 5°. Required an increased tolerance for measurements; more sensitive than the human eye In testing found high degree of success across a wide range of subjects. Therapists will have the system to use on patient. Allows for validation of the grading of the Vail Sport Test. Current status: final testing, bug testing, cleaning up code. © Computer Science Department, Texas Christian University
