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. 2012-2013 Computer Science Department, Texas Christian
University Slide 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. 2012-2013

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.

Slide 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. 2012-2013 Computer Science Department, Texas
Christian University Slide 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.

Slide 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. 2012-2013 Computer Science
Department, Texas Christian University Slide 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. 2012-2013

Texas Christian University Slide 14 Demo Slide 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. 2012-2013 Computer Science
