Most stroke survivors never fully recover hand function, and conventional therapy plateaus within months. SmartVNS is a wearable device that breaks that plateau by combining real-time motion tracking, AI movement classification, and non-invasive auricular vagus nerve stimulation in a single closed-loop system. Stimulation fires precisely when the patient performs a therapeutic movement and is suppressed during compensatory patterns, amplifying neuroplasticity exactly when it matters. Continuous motion data lets therapists personalise therapy remotely, document progress objectively, and lower per-patient treatment cost through automation. The result is faster, more effective recovery, better adherence, and a defensible reimbursement pathway.
