VRehab-SMA Phase 1.2

Spinal muscular atrophy is a genetic disorder where muscles progressively weaken, severely impacting patients' motor abilities eg sitting or walking etc.

Several disease modifying therapies have been developed to treat Spinal muscular atrophy which have led to new disease pathways. For example, previously patients who could not sit can now sit but still not walk. According to standard of care guidelines, exercise programs should be designed and monitored by a physical therapist and should include exercises to improve daily life activities. Exercises should be adapted to each patient and can be prescribed with an optimal frequency in various ways. However in a recent survey, of patients with Spinal muscular atrophy, only 20% report access to endurance exercises and only 6% report mixed exercises. This is due to manpower limitation and difficulties in engaging with young and sometimes highly disabled children.

To address this, the investigators propose the development of an innovative, virtual targeted rehabilitation platform specifically designed for young patients with Spinal muscular atrophy. This technology aims to provide a patient-centric, at-home rehabilitation solution, enabling caregivers to facilitate daily exercises in a more accessible and enjoyable manner. This technology would involve the integration of augmented electromyography signals and soft robotic haptic devices into a game controlled by exercise/movement for children. By increasing the frequency and quality of exercise interventions at home, this technology has the potential to significantly address the critically unmet need for consistent rehabilitation and decrease the burden of hospital-based assessments.

This is a proof of concept study to assess patients with Spinal muscular atrophy desire to use the equipment and the potential benefit this can bring to patients by surveying Spinal muscular atrophy patients about technology and exercise and testing the current equipment in a lab setting.
