Validity Assessment of Sensors for Movement Tracking With Children/Youth With Diverse Neuromotor Abilities

The overall goal of this study is to establish the clinical utility and accuracy of markerless motion captures systems for tracking therapy exercises and movement during game play. Specific aims are: 1. To evaluate the accuracy of the kinematic metrics tracked by marker-less motion capture systems by comparing them to the gold standard marker-based Motion Analysis system. 2. To assess agreement between exercise repetition counts and clinical assessment scores determined from data collected by the markerless motion capture systems compared to the gold standard marker-based Motion Analysis system and a trained clinician. 3. To explore the extent to which kinematic metrics collected during gameplay (e.g. smoothness of movement, symmetry index) can discriminate different motor abilities. 4. To understand children's perspectives on motion capture video games in the context of rehabilitation. Participants will: Perform active range of motion of each joint (3 repetitions, outside of the game environment) and rehabilitative movements within games developed at Holland Bloorview that target anatomical movements (e.g. shoulder abduction/adduction, shoulder flexion/extension, elbow flexion/extension, lateral trunk lean, hip flexion/extension, knee flexion/extension, trunk flexion/extension) Play each mini game until 10 repetitions are made regarding the game objective or 2-minutes of game play is reached.
