Straight answers. If yours is not here, request access and ask us anything.
Yes. Link to any page, and print or send the patient handout as often as you like.
Each range of motion page lists its sources. Most values come from the American Academy of Orthopaedic Surgeons and the AMA Guides to the Evaluation of Permanent Impairment, the two references most clinicians use.
These resources are free to use. MotionArc itself is in early access: pricing is simple and usage-based, and early access includes a free usage allowance so you can try it on real work.
The goniometer on this site runs in your browser and never uploads photos. In MotionArc, clinicians sign a business associate agreement (BAA) with us before any real patient data is entered.
