Balance Retraining Practice Exam

Base of support is the area where the body contacts the supporting surface to stay upright. When sitting, the main contact points are the pelvis against the chair and the feet on the floor. These two points create the stable base that supports the body’s weight and resists tipping in different directions. The trunk and head sit above this base and help with balance, but they aren’t the points of contact that define the base of support. Knees and shoulders aren’t the primary contact with the surface in a typical seated posture, unless you’re using them for additional support, which would change the base. In a standard seated position with feet flat, the pelvis and feet form the base of support.
