What is the name of the rod used as an aid in walking?

The term "cane" refers to a walking aid that is typically a single stick or rod used by individuals for support and balance while walking. Canes are often used by people who may have difficulty walking independently or who need extra stability. They provide a point of support that helps distribute weight more evenly, making walking easier and safer. Canes are lightweight and portable, making them suitable for everyday use.

While options like "walker," "crutch," and "rollator" also serve as mobility aids, they differ in design and function. A walker provides a frame that users can lean on for full support, a crutch typically supports the weight of the body under the arms for those with severe mobility issues, and a rollator has wheels and is designed for individuals who require assistance to walk but still have some mobility. Understanding the specific uses and characteristics of these aids helps clarify why "cane" is the correct answer in the context of a simple walking aid.
