What is the recommended distance between the tops of crutches and the axillae?

The recommended distance between the tops of crutches and the axillae is 2 to 3 finger widths. This spacing is crucial for ensuring proper use of crutches while maintaining safety and comfort for the user.

When the crutches are positioned too close to the axillae—meaning there is no gap or only 1 finger width—the risk of nerve injury, particularly to the brachial plexus, increases. This can lead to numbness or tingling in the arms and hands and may compromise the user's ability to grip the crutches securely.

On the other hand, positioning the crutches too far from the axillae can affect balance and stability. Therefore, maintaining a distance of 2 to 3 finger widths allows for a safe and effective use of crutches, helping to evenly distribute weight and reduce pressure on the underarms, while also enabling the user to maintain effective support and mobility.
