Moving Toward Clinic-Based Motion Analysis: Kinect® Camera as an Example.

Lower extremity injury and the associated rehabilitation that follows represent an enormous source of annual health care costs as well as time lost from activity in the physically active population. Cost effective, quantifiable assessment of lower extremity movement in the clinical setting represents a tremendous improvement in the standard of injury risk evaluation as well as the ability to track patient outcomes.

In the laboratory setting, camera-based three dimensional motion analysis, which are considered the gold standard for dynamic movement assessment, are commonly utilized to assess lower extremity and trunk kinematics associated with lower extremity injury. Cost effective and clinician friendly motion analysis technology that allow for valid and sensitive real time assessment of lower extremity movement patterns are an essential next step toward optimized patient care. The Microsoft Kinect® camera system (Microsoft Corp. Redmond, WA) is a widely available and cost effective video game system accessory that utilizes multiple cameras to measure 3 dimensional joint kinematics.

For the normalized hop values, which improves comparability between sexes, yet, males continue to outperform woman overall. As far as sex differences; males generated greater lower extremity power which may explain better performance on hop tests.

On the other hand, Dynamic Balance Assessment results similar findings between the sexes. Males were better in the posterolateral direction which is similar to previous studies with recreationally active participants.  Also, future research should assess the ability of the Kinect camera system to measure knee and hip kinematics during different tasks such as walking gait or stair climbing.
