Which lateral support is indicated for mild to moderate lateral listing or scoliosis?

• A. Contoured or curved lateral supports
• B. Planar lateral supports
• C. Chest strap
• D. No armrests

Answer: (B)

Planar lateral supports are used when the trunk deviation is mild to moderate because they provide broad, even contact along the sides without forcing the torso into a highly molded shape. This flat, non-conforming surface allows you to establish stable lateral contact to help limit lateral listing while still accommodating breathing and natural movement. They’re easy to adjust with padding and can be positioned to push the trunk toward midline without creating pressure points that a curved, highly contoured surface might cause in less severe curvatures. In contrast, a contoured or curved lateral support is more appropriate when the curvature is pronounced and a tighter fit to the torso is needed to resist lateral flexion. A chest strap or armrest position relates to other aspects of stability and seating support, not the primary lateral support type.
