Capture
A short guided session records the raw signal: taps, steps, speech, or a brief video.
Technology
Why it works.
Parkinson’s is not one symptom. It is a pattern that shows up in how you move, how you speak, and how your face carries feeling. Velsyna reads that pattern where it lives: in the brain’s motor circuits.
The journey below takes about a minute.
This is the brain.
Parkinson's begins deep inside it, in circuits that coordinate movement, speech, and expression. Keep scrolling to travel through them.
Substantia nigra · basal ganglia
Movement starts here.
Deep in the brain, in a region called the substantia nigra, the cells that make dopamine slowly fade. The basal-ganglia circuits they feed lose their rhythm, and the motor cortex fires the muscles slowly. Steps shorten, taps slow, handwriting shrinks. Velsyna measures that rhythm with a tapping test and a short walk.
Finger tapping · gait
Laryngeal motor cortex
The voice follows.
The same quieted circuits move the muscles of the voice box. Speech becomes softer and flatter, often before anyone names the change. A short reading lets Velsyna hear it.
Voice · volume and pace
Facial motor pathways
Expression fades quietly.
The automatic, emotional engine of facial movement quiets, so the face expresses less. Clinicians call it the masked face. A brief video measures it, gently.
Expression · facial motion
Three signals. One picture.
Together they describe how Parkinson's is moving. Velsyna turns them into standardized scores your clinician can trust.

From a tap to a number your clinician can trust.
02
Extract
The signal becomes precise measurements: speed, rhythm, pauses, and how they decay.
4.2 taps/s · 12% decay· 180 ms variance
03
Score
Each measurement lands on the 0 to 4 scale used by the MDS-UPDRS, so the result already speaks your clinician’s language.
04
Trend
Scores build into a timeline. Change becomes visible in weeks, not visits.
Grounded in the science of Parkinson’s.
Every signal Velsyna measures is drawn from decades of published clinical research. The measurement approach follows the evidence, and the evidence is public.
