Which is NOT a mechanical aid for walking?

• A. Stroller
• B. Walker
• C. Cane
• D. Crutches

Answer: (A)

The main idea is to identify devices that support ambulation versus those that are used to transport someone. Mechanical aids for walking are tools that help a person stand, balance, or move with less effort—like a cane, crutches, or a walker. A stroller, while wheeled, is designed to transport a child or dependent and is pushed by another person; it does not provide the user with support to stand or walk or enable independent ambulation. That’s why it isn’t a mechanical aid for walking. The other options fit as walking aids: a walker offers a stable frame for support, a cane helps with balance and load distribution, and crutches distribute weight through the arms to relieve the legs.
