What do wheelchair components provide in tone management?

• A. Improved speed and agility
• B. Support for low tone areas and inhibit high tone areas
• C. Increased endurance
• D. Aesthetic alignment

Answer: (B)

Wheelchair components manage tone by providing stable, aligned support that helps regulate muscle activity. When the seating system supports areas with low tone, it prevents collapse and promotes better postural control. At the same time, proper positioning and contact with supportive surfaces give cues that can dampen excessive muscle activity in high-tone areas, reducing reflexive guarding. A well-contoured seat cushion and backrest align the pelvis and trunk, while lateral supports and correct leg/foot positioning help maintain symmetry and limit overactivity in hypertonic muscles. The result is a balanced base that allows safe weight bearing and gradual, controlled stretch, which helps normalize tone. These components aren’t primarily about speed, endurance, or cosmetic appearance; their main role is to support low-tone regions and inhibit high-tone activity for better overall tone management.
