MagicTrain · Working beta · New South Wales
Rehab at home, with your physio still in the loop.
Your phone camera tracks 33 body points while you do the exercises your physiotherapist prescribed. MagicTrain counts the reps, measures the joint angles and sends your physio a report after every session.
No hardware to buy. Works with the camera on the phone or laptop you already have.

How it works
MagicTrain is AI-guided home rehabilitation for physiotherapy patients.
Three steps, and your physiotherapist stays in the loop at every one of them.
Upload the plan your physio gave you
A photo of the exercise sheet is enough. MagicTrain turns it into today's session: exercises, sets, reps and the cues your physiotherapist wrote.

- Glute bridge · 3 × 12
- Step-up · 2 × 8
Do the session in front of your camera
The camera tracks 33 body points in real time. Reps are counted, joint angles measured and form is flagged, all on your device.
- Rep 6 / 10
- Knee 92°
- Depth reached
Your physio gets the report
Angles per rep, tempo, flagged reps with a still frame, and the trend across weeks. A video consult is one tap away when something needs a look.

What the camera sees
Numbers your physio can act on, not a score out of ten.
Each rep becomes a row of measurements. The same joint angles a physiotherapist would read off a goniometer, captured on every rep, at home.
| Joint | Angle error (MAE) | Agreement (ICC) |
|---|---|---|
| Knee | ≤ 5° | ≥ 0.75 / ≥ 0.90 |
| Hip | ≤ 7° | ≥ 0.75 / ≥ 0.90 |
| Ankle | ≤ 10° | ≥ 0.75 / ≥ 0.90 |
| Shoulder | ≤ 10° | ≥ 0.75 / ≥ 0.90 |
ICC ≥ 0.75 good, ≥ 0.90 excellent. Evaluation pipeline and thresholds, not results. Ground truth: Qualisys marker-based motion capture from the public BioCV dataset.
Evidence
Scored against marker-based motion capture.
Before a model ships, its joint angles are compared with optical marker-based motion capture on the same movements. We publish the thresholds a model has to clear, so a physiotherapist knows what the numbers mean.
Technology
Trained on NVIDIA H200 and B300.
We train MagicTrain's pose and movement-quality models in PyTorch with CUDA on NVIDIA H200 GPUs, and rent NVIDIA B300 capacity for the larger training runs.
Pose and movement-quality models
PyTorch with CUDA on NVIDIA H200; larger runs on rented NVIDIA B300 capacity.
H200 in-house · B300 rented for larger runs
33-landmark pose in the browser
Pose estimation runs on the phone or laptop GPU. Raw video never leaves the device; measurements and, if the patient opts in, still frames of flagged reps go to the physiotherapist.
Marker-based ground truth
Joint-angle MAE and ICC against Qualisys marker-based motion capture (BioCV), with acceptance thresholds set per joint.

For physiotherapists
You prescribe. MagicTrain shows you what happened between visits.
- A report after every session: angles per rep, tempo, flagged reps with a frame.
- A patient list with adherence and trend, so the next appointment starts from data.
- Video consultations from the same portal when a movement needs your eye.
