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.
Aged 5 to 24 years
Sufficient motor skills to successfully play the game (i.e., able to lift hand above shoulder)
Able to see and interact with the monitor - minimal visual or auditory impairments
Willing to wear reflective stickers on skin and on tight fitting clothing
Any injury/disability that would make moderate exercise unsafe.
History of epilepsy aggravated by screen time. For the latter, the child will be eligible to participate if they safely participated in 1 hour of TV/video games per week as reported by the parent.
Study population will include clients recruited through Holland Bloorview Kids Rehabilitation Hospital as well as through community postings
Case-only
Cross-sectional
Validity Assessment of Sensors for Movement Tracking With Children/Youth With Diverse Neuromotor Abilities
DeviceParticipants will play active video games by moving their bodies while their movements are tracked by different sensors.
Standardized Clinical Assessment: 30 Second Sit To Stand Test
A measurement that assesses functional lower extremity strength.
Standardized Clinical Assessment - Five Times Sit to Stand Test
The Five Times Sit to Stand Test measures one aspect of transfer skill. The test provides a method to quantify functional lower extremity strength and/or identify movement strategies a patient uses to complete transitional movements.
Standardized Clinical Assessment: Paediatric Reach Test
A modified form of the Functional Reach Test (FRT). The PRT measures side reaching as well as forward reaching in both sitting and standing positions.
Standardized Clinical Assessment: Single Leg Stance Test
Used to assess static postural and balance control
