Exacta Transparent Protractor Goniometer Extremity Measurer is a protractor with two arms that measures angles.
Measuring Lateral Rotation of the Shoulder Joint
Lateral rotation is measured from 0 to 180 degrees and uses the shoulder joint as a central point of reference. The norm range of motion is about 170 degrees.
Measuring Hyper Extension of the Shoulder Joint
Hyper extension of the shoulder joint is measured in degrees of backward flexion. Using the shoulder joint as a point of reference, the shoulder joint range of motion in hyper extension can be measured. The normal angle of hyper extension is 50 degrees.
Measuring Flexion and Hyperextension of the Hip Joint
The average range of movement for flexion of the hip joint is 110 degrees. Flexion is measured from the horizontal neutral position vertically up without lifting the hips from the floor. Use the hip joint as a reference point for both flexion and hyperextension. Hyperextension of the hip is measured from the neutral line backwards, and normal hyperextension measures 20 degrees.
Measuring Flexion, Hyperextension, Radial, and Ulnar Deviation of the Wrist Joint
A goniometer can be used to measure range of motion at the wrist in forward and backward movement, as well as side-to-side. Wrist flexion and extension occur both in the sagittal plane. Normal value of wrist flexion is 80 degrees and extension is 70 degrees. For ulnar deviation, the hand should be in a pronate position on the table. The capitate is the axis point. By deviating the wrist to the left and then right side, ulnar deviation can be measured.
Measuring Finger Range of Motion
A goniometer can also be used to measure the range of motion in the MCP, PIP, and DIP joints. MCP Extension is measured using the knuckle as the axis point. PIP flexion range of motion can also be measured to determine the active range of motion.
