For C5 Quadriplegia, which manual wheelchair handrim type is described?

• A. Standard Handrims
• B. Handrim Projections
• C. Friction Surface Handrims
• D. No Handrims

Answer: (B)

When propulsion needs to be achieved with limited finger control, the rim design should maximize leverage and ease of contact. A person with C5 quadriplegia typically has elbow flexion and shoulder movement but weak or absent finger function, so the mechanism that allows pushing on an extended surface without wrapping the hand around the rim is ideal.

Handrim projections extend outward from the wheel’s rim, giving a lever-like contact point you can press with the palm or back of the hand. This increases contact area and mechanical advantage, letting the user propel the chair with minimal finger dexterity. Friction surfaces still rely on some grip, standard rims require a firmer grasp, and no handrim implies a different control method altogether, which isn’t as suitable for this level of impairment. So the projection design best matches the functional needs of someone with this level of injury.
