Tilt-in-space wheelchair is indicated for which condition besides pressure relief?

• A. Upper cervical SCI unable to pressure relief
• B. Trunk extensor spasms
• C. Bariatrics
• D. Pes planus

Answer: (B)

Tilt-in-space seating redistributes pressure while stabilizing the body's posture. When trunk extensor muscles go into spasms, the torso tends to extend forcefully, making it difficult to sit in a stable, comfortable position. Tilting the chair backward changes the orientation so the pelvis can assume a more neutral or posterior tilt, which lessens the demands on the extensor spasms. This support reduces reflexive extension, improves spinal and pelvic alignment, and allows the person to sit longer with less pain or discomfort. With a more stable trunk, the person can use the arms more effectively for activities, since the shoulders and elbows aren’t fighting to compensate for an unstable core. Pressure relief remains a benefit, but the key advantage for trunk extensor spasms is the enhanced stability and tolerance to sitting provided by the tilt. Other options don’t address trunk control and stability in the same way.
