10. Three-Point Pressure System in the Boston Scoliosis Brace Primary Pressure Point (Corrective Force): The primary corrective force is applied to the apex of the curve or the most prominent area of the spinal deformity. This pressure is exerted through pads placed inside the brace. For example, in a right thoracic curve, the pad would be placed on the right side of the rib cage, pressing on the ribs to move the spine back towards the midline. Counteracting Pressure Points: To balance the corrective force and stabilize the spine, two counteracting pressure points are applied above and below the primary pressure point. These counteracting forces are exerted in the opposite direction of the primary force to create a balanced system, preventing the spine from simply shifting away from the primary pressure point without correction. One counteracting pressure point is typically located on the opposite side of the body at a point above the curve (e.g., on the left side of the rib cage in a right thoracic curve), and the other is located below the curve, often on the pelvis or lower spine. Purpose of the Three-Point Pressure System The goal of this system is to create a mechanical advantage that helps reduce or stabilize the curvature by applying pressure on specific points along the spine. This pressure system works to realign the spine, encourage more balanced muscle activity, and prevent further progression of the curve. Summary The Boston Scoliosis Brace uses a three-point pressure system where the primary corrective force pushes against the apex of the spinal curve, while two counteracting forces stabilize and balance this pressure above and below the curve. This system is essential for the brace's effectiveness in managing scoliosis in patients.
