What is the primary purpose of using a cane for a patient with weakness?

The primary purpose of using a cane for a patient with weakness is to provide support and stability. Canes are designed to enhance balance and reduce the risk of falls by offering an additional point of contact with the ground. This is particularly important for individuals who may have decreased strength or coordination, as it helps distribute weight more evenly and allows the patient to move safely.

When using a cane, the patient can rely on it for support, which improves their confidence in mobility and encourages independence during movement. It can help compensate for weakness on one side of the body, allowing for easier navigation around obstacles and in different environments. The other options, while they may have some relevance, do not capture the primary role of a cane, which is fundamentally about enhancing stability and support during ambulation.
