Freeform Hip Goniometer

Hip range of motion measurement, simplified!
Simply place the phone on thigh, tap to start, then move the hip freely. The app automatically calculates the motion in each plane of movement. No need to stop between each position to obtain a measurement!

Planes of motion calculated:
-Abduction
-Internal and external rotation (in extension)
-Internal and external rotation (in flexion)
-Flexion
-Pure sagittal plane flexion

Also includes support for preexisting hip flexion contractures.
