Massage Therapist

Answer: D The client is positioned in front of a Plumb Line in order to evaluate their symmetric posture. A plumb line is commonly used for postural reference. Sometimes a plumb line is merely a string attached to the ceiling with a weight on the bottom to hold it in place and to line up a straight reference point. Other professionals have complete standing grids with strings intersecting in horizontal and vertical positions to create a grid pattern. The client is instructed to face forward, to the side and backward in order for the therapist to gain various postural views.
