Ambulatory Devices: Assessment and Prescription

Injuries or disabilities associated with the lower extremities and aging frequently result in ambulation difficulty and this usually necessitates the prescription of ambulatory assistive device (e.g., cane, crutch and walker) in an attempt to restore locomotory function. Ambulatory devices are orthotic devices that provide support, stability and balance for users to able to move from one point to another. Users can progress or retrogress from one ambulatory device to another while some are permanently fit on a particular device throughout lifetime. The progression is dependent on the medical condition, user’s abilities, user’s anthropometric and environment. Physiotherapist prescribes ambulatory device to users and helps with the fitting and proper use of the ambulatory device. A correct prescription and well fitted ambulatory device minimize functional limitation and promote functional ability and improve quality of life. Incorrect prescription, fitting and use of ambulatory device may result in early fatigue, frustration, fall and damage to blood vessels, muscles or nerves
