Which type of assistive technology can positively impact bone mineral density?

• A. Wheelchair cushions
• B. Standing devices
• C. Manual wheelchairs
• D. Speech amplification devices

Answer: (B)

Weight-bearing through the legs in an upright position stimulates bone remodeling (Wolff's law). Standing devices provide a safe way for individuals with cerebral palsy to achieve axial load on the bones of the lower extremities and pelvis, which over time increases bone mineral density and can reduce fracture risk. In CP, limited mobility often leads to low BMD, so a standing program helps counteract this by converting gravitational forces into bone formation, especially when standing sessions are regular and properly aligned. The load from standing is more effective for increasing BMD than sitting or passive seating, which don’t provide the necessary axial forces. Other options primarily address comfort, mobility, or communication, not weight-bearing bone stimulation. Therefore, standing devices are the best choice for positively impacting bone mineral density.
