Ever Ready First Aid Top Quality 12 inch Protractor Goniometer with 360 degree coverage with 1- degree increments to ensure ISOM accuracy. Measurements in inches and centimeters are also available on the arm of the goniometer.

Review: To measure something like degree of knee flexion after knee surgery, this works - VERY nice protractor and easy to use and easy to read. Got it to measure knee flexion after knee surgery ( a really key indicator of recovery). Well made.
Review: Works well - I'm not a PT but needed this for a knee injury. 1. Larger tool is better for your eyes HOWEVER 2. Smaller tool better for when you need to transport it, or when there is something blocking the limb like a table or something depending on which position you are using it for. In general I am a little disillusioned with these bc it could be 1-20 degree difference depending on where you point the ends. But I guess good to see the numbers inching up and you know progress is being made.

## Questions & Answers

**Q: is this hard plastic? or does it bend easily?**
A: It is pretty stiff, but will bend gently and slightly ~10-30 degrees under pressure, rather than break.  But left alone, it stays straight.

**Q: What the uncertainty principle on this goniometer?**
A: I'm not sure I understand the question. I used it to measure my knee after total knee replacement. It lets you know the degrees of where your at for the curve and when its straight. 12 years ago your knee had to be 180 for it to be straight and then they liked it around 110 for the bend. Last year when I had the other knee done you came out of surgery at 180 degrees so you only needed to measure for the bending of your knee

**Q: Will this work for elbow ?**
A: It is designed to measure angles of joints, so although its larger size accomodates hip and knee joints, it also may be used to check elbows.

**Q: What is the radius of the ruler?**
A: From the center pivot to the end of the arms is ~10".
