When assessing the client’s static posture a plumb line is used to represent a line of reference (a plumb line is a cord with a plumb bob attached to it to provide an absolute vertical line).
The point in line with which a plumb line is suspended must be of a standard fixed point. Since the only fixed point in the standing posture is at the base where the feet are in contact with the floor, the plumb should be aligned at this position.
The assessment should begin with the anterior view with the client facing you while standing behind the plumb line. You should start from the feet and work your way up to the head. Repeat this process next for the coronal (side) view then lastly with the posterior view.
