Help test Vexa —
cervical dystonia with DBS.
Testing is small on purpose: a first group of up to 30 people with cervical dystonia and a DBS system, so every tester gets a real reply from a real person. Applying takes two minutes. If you're accepted you'll get an invitation from Apple TestFlight by email, usually within a few days.
Please read before applying. Vexa is a monitoring tool, not a medical device, and the severity numbers it shows are experimental — consistent, but not yet validated against clinical scales. It will not tell you what to change and should never replace your neurologist's judgment. The programming log, session history, notes and report are solid and useful today; the measurement is what you'd be helping us validate.
