When fitting a wheelchair for a child with cerebral palsy, which body region's alignment is examined FIRST to influence seated posture?

• A. Pelvis
• B. Lower Extremities
• C. Head
• D. Spine

Answer: (A)

The pelvis sets the foundation for seated posture. In a child with cerebral palsy, how the pelvis sits on the seat largely determines how the rest of the body aligns. A neutral, level pelvis with balanced weight on the sit bones provides a stable base that allows the spine to align and the head to position itself more easily. If the pelvis tilts or rotates, the trunk will compensate, leading to asymmetry and less stable posture. Therefore, during wheelchair fitting you first assess and correct the pelvis—using cushions, wedges, or supports to level and symmetrically load the ischial tuberosities—so that subsequent adjustments to the spine and head can be more effective.
