When using a non-adjustable flat backrest, the top por- tion of the upholstery will usually push the trunk forward of the center of gravity over the pelvis. To maintain the trunk in the upright posture, the user must have and use the back extensor musculature, or add tilt or recline to backrest (FIGURE 3).

The best point of control for the pelvis is near the Poste- rior Superior Iliac Spine (P.S.I.S). The upper trunk should be relined until a balance posture is achieved, approxi- mately 10 to 15 degrees (FIGURE 5).

When using adjustable upholstery, it is possible to tighten the lower portion of the backrest which assists in main- taining a neutral pelvis. The upper portion can then be adjusted to follow the natural curvature of the spine bring- ing the trunk back over the pelvis in a position of balance relative to the center of gravity (FIGURE 4).
