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

Great tool for checking range of motion for bionic knee. Pros: Looks and functions like the tool used physical therapy, portable, easy to use, nice price point. Cons: None yet. I recommend this tool and would buy it again.

My wife had a serious knee injury and has been in therapy to regain extension and flexure. The hospital therapist used a device exactly like this to measure improvement. We wanted to have a device like it so that we could check progress at home. This one is perfect. Exactly as used by the pros.

The goniometer worked well in measuring how much bend I was getting in my knee. It was good to keep track of progress after knee replacement surgery.

Good

I had to buy this for chiropractic school/practice, and it does the job. It is a cheaper plastic than a nice one and quite flimsy. Stick this in your chiro table bag and let it hang out but don't be surprised if it breaks or cracks. The rivet is a little sticky and does not allow fully free motion, it'll sometimes require two hands to get it to move. Other than that the numbers are painted on so as you use it and it breaks in expect the rivet to loosen but the numbers to get more difficult to read. Pros: I needed it for a grade and to get used to using one. This does that 1000% Neg: This is not a professional model. You get what you pay for. I have recommended this to others, but I will be replacing after graduation.
