Assistive devices for mobility/ambulation can be referred to as ambulatory aids. Ambulatory aids (eg, canes, crutches, walkers) are used to provide an extension of the upper extremities to help transmit body weight and provide support for the patient. The type of ambulatory aid needed depends on how much balance and weight-bearing assistance is needed.

Generally, the more disabled the individual is, the greater the complexity required in the walking device. A walker supplies the most support, and a standard cane provides the least.
