Why Physical Therapy Motion Tracking Works Here
Live joint angle readout
Elbow and knee bend shown in degrees directly on the tracked skeleton, updated every frame.
Track just the region you need
Body Region presets (Full/Upper/Lower) and individual joint-group toggles let you focus tracking on the relevant limbs.
Export tracking data to CSV
Motion Tracking Data Export saves per-frame coordinates and speeds for review outside the app.
Smooth Jitter option
An exponential smoothing toggle reduces frame-to-frame joint jitter for a steadier readout.
Works from a recorded clip too
Load a video of an exercise session (not just live webcam) and Render Mode will process it frame-accurately.
Private by design
No frame is ever uploaded — all tracking and analysis happens locally in the browser.
Frequently Asked Questions
Is this a medical device or diagnostic tool?
No — it's a general-purpose visual pose tracker, not a certified clinical measurement device.
How accurate are the joint angles?
They're computed geometrically from tracked keypoint positions — accurate enough for visual form/range checks, not lab-grade biomechanics.
Can I track just one limb?
Yes — use the Track Joints toggles or Body Region presets to focus on Arms or Legs only.
Can I save the numbers, not just the video?
Yes — Motion Tracking Data Export writes tracked coordinates/speeds to a CSV file.
Does it need special hardware, like a depth camera?
No — any regular webcam or uploaded video works.
