HZMM Goniometer 12 inch, Transparent Orthopedic Angle Ruler Plastic Goniometer, 360 Degree Clear Protractor Physical Therapy for Body Measuring Tape Goniometer Protractor Ruler

Best used if other person does measuring. Helped post op to determine progress.

Great easy to read goniometer

Bought this as a gift for my physical therapist who just opened his own practice and hadn’t bought one yet. Inexpensive and works well. Dr. uses it weekly to gauge my progress after surgery.

A handy tool for someone whose had a knee replacement and wants to monitor their range of motion after having completed physical therapy.

This product measures a knee’s range of motion accurately. The only problem I have with it is that the plastic is a little brittle. I was outside and a wasp buzzed me. I used the first thing I could find to swat it with and some of the plastic shattered. To be fair, it was not marketed as an insect swatter.
