How does severe spinal deformity affect seating for a student with profound neurological damage?

• A. The student can still sit upright in a standard wheelchair.
• B. The student cannot sit up and requires a reclining wheelchair.
• C. The student must stand with support.
• D. The student should be placed in a prone position.

Answer: (B)

Severe spinal deformity disrupts the ability to hold the trunk upright, and when combined with profound neurological damage, the muscles that normally support sitting are often too weak or uncoordinated to maintain a stable, upright position. The goal of seating in this situation is to keep the head, trunk, and pelvis in a safe, aligned posture, while distributing pressure to prevent skin breakdown and reducing strain on the spine and breathing mechanics. A reclining wheelchair provides adjustable support and allows the sitter to be positioned with a backrest and seat that follow the natural curves of the spine, maintaining alignment even with deformity. It also enables tilt and recline to improve comfort, respiration, digestion, and circulation, and to accommodate fluctuations in tone and fatigue throughout the day. Standing with support would require more postural control than is available, and prolonged prone positioning is not practical for daily seating needs and comfort.
