Disability and mobility problems increase with age. Assistive devices such as canes, crutches, and walkers can be used to increase a patient's base of support, improve balance, and increase activity and independence, but they are not without significant musculoskeletal and metabolic demands. Most patients with assistive devices have never been instructed on the proper use and often have devices that are inappropriate, damaged, or are of the incorrect height. ⋯ The top of a cane or walker should be the same height as the wrist crease when the patient is standing upright with arms relaxed at his or her sides. A cane should be held contralateral to a weak or painful lower extremity and advanced simultaneously with the contralateral leg. Clinicians should routinely evaluate their patients' assistive devices to ensure proper height, fit, and maintenance, and also counsel patients on correct use of the device.
