Place the sensors
One on each limb, in the same spot every time. They pair over Bluetooth in seconds. No cameras, no markers.
PL1 is a wearable sensor system that turns physiotherapy exercises into objective data in real time.
In development. Early access for clinics and researchers.

Physiotherapy sessions get recorded in notes, but rarely benchmarked. Notes capture what was done, not how well it was done, and without an objective reading to compare against, changes in range and symmetry go unnoticed until they matter.
Benchmarked, not just noted

One on each limb, in the same spot every time. They pair over Bluetooth in seconds. No cameras, no markers.
Perform the prescribed physiotherapy movements. The sensors track orientation continuously, through every repetition.
Joint angle and left against right symmetry appear live on screen, and are saved to the patient record.
This is the reading PL1 takes, and the threshold it's measured against. Move the arm and watch a limb go from within range to a flagged deficit.

The exercise and the app, recorded side by side, so you can watch the numbers move with the limb.
Every session adds to a trend: how close the injured limb is to the healthy one, range of motion side by side, and how far things have moved since the first reading.


Sensor units worn on both limbs at once, streaming to the clinician app. We're actively expanding what PL1 measures.

Orientation and movement captured continuously. No cameras and no line of sight required.
Joint angle, repetitions and left against right symmetry read as the movement happens.
Pairs straight to the clinician app and streams live.
Every session stored against the patient record for review.
Plato argued that physical training and intellectual training had to advance together. Neither works properly alone. Movement and measurement belong together. That is what we build.
Working with physiotherapists, clinics, sports and performance teams ahead of launch.
