Step 2: Put an X on the anterior axillary lines and then measure the distance between the anterior axillary lines.

Step 3: Put an X on the bottom corners of the shoulder blades and measure the distance between them.

Step 4: Put an X on the posterior axillary lines and measure the distance between them.

Step #5: Measure the circumference of the rib cage from the highest point of the deformation.
