ionic develops a wearable, non-invasive neuromodulation device for gait impairment and lower-limb spasticity linked to neurological disease and injury. The company positions the Neural Sleeve as a prescribed medical device used in everyday walking contexts.

The system combines embedded motion sensing with multi-channel functional electrical stimulation delivered to key leg muscle groups. Algorithms adapt stimulation timing and intensity to the user’s gait cycle, with parameter control and progress tracking supported through a companion app.

Primary use cases include foot drop, muscle weakness, and spasticity in conditions such as multiple sclerosis, stroke, cerebral palsy, and spinal cord injury. Deployment is positioned for home use with clinician onboarding and integration into rehabilitation pathways alongside standard mobility care.
