lo 4.6. how do you use a goniometer?
flex the joint to 90 degrees and read the angle from the goniometer.
estimate the joint angle by eye - balling it instead of using a goniometer.
identify the joint, position the goniometer on it, move the joint through its full range of motion, and read the angle from the goniometer.
place the goniometer on the joint and read the angle without moving the joint.
place the goniometer on the opposite side of the joint

Explanation:

A goniometer is used to measure joint - range of motion. First, the joint is identified, then the goniometer is positioned on it. The joint is moved through its full range of motion, and the angle is read from the goniometer. Flexing to a specific angle like 90 degrees is not the general way, eye - balling is not using a goniometer, reading without moving the joint won't measure range of motion, and placing on the opposite side is incorrect.

Answer:

Identify the joint, position the goniometer on it, move the joint through its full range of motion, and read the angle from the goniometer.
