Which device requires strong upper extremity and trunk?

• A. Forearm crutches
• B. Parallel Bars
• C. Walker
• D. Quad Cane

Answer: (A)

Working with forearm crutches demands the most from the upper extremities and the trunk because you bear a large portion of your body weight through the hands and forearms while you simultaneously keep the torso stable and aligned with each step. The grip must be strong, the wrists and elbows must control the crutches, and the core must brace to maintain balance and posture as you advance. In comparison, parallel bars provide a fixed, supportive frame that reduces the load borne solely by the arms, making balance easier but still requiring upper-body and trunk engagement. A walker offers a broad base and you push it forward, distributing weight more across the arms and the device itself, which generally lowers the demand on isolated arm strength. A quad cane has the widest base and least reliance on upper-extremity strength, with more weight support through the leg and the cane.
