Which statement best describes the one-hand drive frame?

• A. Self-propels using one UE
• B. Self-propels using both UEs
• C. Requires two-handed propulsion
• D. Not suitable for active users

Answer: (A)

The main idea is that a one-hand drive frame is built so the chair can be propelled with a single arm. Its propulsion system is arranged on one side or uses a lever or single handrim that translates the effort of one hand into wheel rotation, giving independent mobility when one arm is weak or unavailable. This design contrasts with standard setups that require two hands to drive, and it isn’t about being unsuitable for active users; rather, it enables independence for those with unilateral impairment. So the best description is that it self-propels using one upper extremity.
