Gait disorders in the elderly are common and in most cases cannot be treated medically or surgically. Therefore, treatment often relies on ambulatory devices such as canes, crutches, and walkers. Before selecting a device, the patient should be evaluated to define whether one or both upper extremities are required to achieve balance or bear weight.
