Overview

"In the context of limited accessibility to prolonged and efficient rehabilitation programs based on physical activity, this study aims to develop a home program for children with chronic diseases affecting physical health (including cerebral palsy, obesity, and neuromuscular diseases). The French company EzyGain has designed a compact treadmill equipped with sensors and a safety system, which communicates with a tablet application and a virtual reality headset to support at-home rehabilitation. This study seeks to advance the development of this solution into a prolonged and progressive training program, tailored to positively impact children's health. Future users, including children, their parents, and therapists, will be at the heart of the development process. A qualitative methodology will be employed, incorporating focus groups and a series of user experience (UX) questionnaires. The research hypothesis is that user feedbacks will enable the development of an appropriate solution that meets their specific needs and ensures high adoption rates of the device. This study is the first step before assessing the impact of the solution in these 3 groups of children (with cerebral palsy, obesity and neuromuscular disease)."

"Visit 1: Children, accompanied by one of their parents, will test the treadmill and the associated rehabilitation games on a tablet and in immersive virtual reality in its current version, and UX questionnaires will be administered. Visit 2: Children, parents, and therapists, in groups of 6 to 8, will participate in focus groups during which they will express their opinions regarding the solution they tested in Visit 1 and discuss areas for improvement. (several monthsare dedicated to the developpement of the solution by the society, based on the children, parents and therapists' feedbacks) Visit 3: Children, accompanied by one of their parents, will test the treadmill and the associated rehabilitation games on a tablet and in immersive virtual reality in its new version, and UX questionnaires will be administered."

Outcomes

Primary Outcomes

Focus group outputs

List of topics addressed during the focus groups by patients, parents, and therapists. The topics will include: the needs and expectations of an at-home rehabilitation tool including virtual reality, perceived barriers and facilitators, and acceptability related to certain features of the solution.

Time frame: Between the second and third week

Secondary Outcomes

User Experience Questionnaire (UEQ-S)

UX will be evaluated using the French short version of the User Experience Questionnaire (UEQ-S). It contains 8 items grouped into two scales: pragmatic qualities (efficiency, clarity, dependability) and hedonic qualities (stimulation, novelty). The format of the items is a semantic differential (e.g., Complicated - Simple) with a 7-point Likert scale.
