Integration of Real-Time Motion Tracking and Pediatric Rehabilitation (Snipperfinger)

Evaluating the Feasibility, Usability, and Integration of the OptiTrack Motion Capture System in Inpatient Physical Therapy

Emerging technologies that utilize motion capture integrated with engaging software offer new methods for increasing engagement and movement in patients admitted to the hospital. Hospitalized patients are often limited to sedentary activities, spending the majority of their time in bed, which can contribute to deconditioning and functional mobility deficits. This study seeks to explore the feasibility of a tool designed to promote movement through engaging gameplay that is acceptable to both clinicians and families.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Pediatric patient; Pediatric patient will engage with engagement-focused software platform (Snipperfingers) and movement will be analysed by the real-time motion capture system (the OptiTrack system).	Behavioral: Snipperfingers; Snipperfinger is a self developed engagement focused software platform designed to encourage participation in pediatric physical therapy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluate the ease of use of Optitrack system measured by System Usability Scale (SUS)	10-item questionnaire with a scale from 1- 5, 1 being strongly disagree to 5 being strongly agree on a five-point Likert scale to measure usability.	Post-simulation (5 minutes)]

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Setup time required for system use	Time required to set up the system, defined as the duration from participant arrival in the gym to the start of the physical activity.	Before intervention
Duration of gameplay-driven physical activity	Time from first recorded movement in response to gameplay to last movement as recorded by OptiTrack motion capture or clinician observation	immediately at the start of intervention, immediately after intervention
Evaluation parent's perception of patient's engagement.	Parent acceptance of the system will be evaluated by self developed questionnaire. The questionnaire contains 10 items with scale from 1-5, 1 being strongly disagree to 5 being strongly agree on a five-point Likert scale.	immediately after intervention
Acceptability of Intervention Measure (AIM) survey	This questionnaire consists of 4 items. Measures are to be graded using a 1-5 scale, from 1=completely disagree, to 5= completely agree	immediately after the intervention
Intervention Appropriateness Measure (IAM) survey	This questionnaire consists of 4 items. Measures are to be graded using a 1-5 scale, from 1=completely disagree, to 5= completely agree	immediately after the intervention
Feasibility of Intervention Measure (FIM) survey	This questionnaire consists of 4 items. Measures are to be graded using a 1-5 scale, from 1=completely disagree, to 5= completely agree	immediately after the intervention
ISO 9241-400	6-item ergonomic questionnaire with a scale from 1- 5, 1 being strongly disagree to 5 being strongly agree on a five-point Likert scale.	immediately after intervention
