What type of assistive device is used by patients to aid in walking?

Crutches are a type of assistive device specifically designed to provide support and stability while walking, especially for those who may have difficulty using one or both legs. They function by allowing the user to transfer weight from their lower extremities to the crutches, thus facilitating movement and helping patients maintain mobility during recovery from injuries or surgeries.

In contrast, walkers offer additional support, particularly for individuals who may require more stability than crutches provide. Canes serve a similar purpose to crutches but are generally intended for those who need assistance with balance rather than full weight-bearing support. Wheelchairs are mobility devices designed for those who cannot walk at all or have severe limitations in mobility, thus serving a different function altogether.

Each of these devices has its specific uses and is selected based on the individual's needs, strength, and level of mobility. Crutches are particularly useful for individuals who are able to bear some weight on their legs but require additional support while walking.
