Which option is designed so the user can operate brakes with coordinated motor ability?

• A. Toggle/lever brakes
• B. Planar lateral supports
• C. Chest strap
• D. No armrests

Answer: (A)

The design aim is to enable braking with controlled, simple hand movements. A toggle or lever brake uses a lever action that translates a clear, intentional movement into braking force, often requiring less precise finger control and more gross motor action. This makes it easier for users to operate the brakes reliably and quickly, preserving independence and safety. Other options serve support or stability rather than brake activation: planar lateral supports help with trunk alignment, a chest strap stabilizes the upper body, and removing armrests changes balance and support. None of these directly improve the ease or reliability of braking, whereas a toggle/lever brake is specifically designed for operation with coordinated motor ability.
