Spiral Analysis turns a spiral drawn on any tablet into objective measures of smoothness, speed, and pressure. Whether you're a researcher, a medical professional, or just curious, this non-invasive tool makes it easy to gain insights into hand stability.
From pen stroke to longitudinal record in three steps.
01
Draw the spiral
The patient traces an Archimedean spiral on a tablet — no wires, no specialist hardware. Takes under two minutes.
02
We analyze the trace
Every point (x, y, pressure, time) is decomposed into smoothness, speed, pressure, and consistency indices.
03
Track over time
Saved as an objective baseline so subtle change is visible session over session.
GROUNDED IN RESEARCH
Built on a clinically validated method.
Digitized spiral drawing is an established, non-invasive technique for characterizing upper-limb motor performance and detecting subtle change — studied across movement disorders for over two decades.
