| Summary: | <h3>Objectives </h3> <p>To determine whether a dual-camera markerless motion capture system can be used for lower limb kinematic evaluation in athletes in a preseason screening setting.</p> <h3>Design </h3> <p>Descriptive laboratory study.</p> <h3>Setting </h3> <p>Laboratory setting.</p> <h3>Participants </h3> <p>Thirty-four (n=34) healthy athletes.</p> <h3>Main outcome measures </h3> <p>Three dimensional lower limb kinematics during three functional tests: Single Leg Squat (SLS), Single Leg Jump, Modified Counter-movement Jump. The tests were simultaneously recorded using both a marker-based motion capture system and two Kinect v2 cameras using iPi Mocap Studio software.</p> <h3>Results </h3> <p>Excellent agreement between systems for the flexion/extension range of motion of the shin during all tests and for the thigh abduction/adduction during SLS were seen. For peak angles, results showed excellent agreement for knee flexion. Poor correlation was seen for the rotation movements.</p> <h3>Conclusions </h3> <p>This study supports the use of dual Kinect v2 configuration with the iPi software as a valid tool for assessment of sagittal and frontal plane hip and knee kinematic parameters but not axial rotation in athletes. </p> <h2>Other information</h2> <p>Published in: BMJ Open Sport & Exercise Medicine <br> License: <a href="http://creativecommons.org/licenses/by/4.0" target="_blank">http://creativecommons.org/licenses/by/4.0</a> <br> See article on publisher's website: <a href="http://dx.doi.org/10.1136/bmjsem-2018-000441" target="_blank">http://dx.doi.org/10.1136/bmjsem-2018-000441</a></p> |
