Abstract
Abstract A therapeutic walker has features which permit its use by persons with varying degrees of disability and is capable of adaptation to be used in different ways as the level of disability diminishes. A walker frame extends substantially around three sides of the region occupied by person using the walker and a removable closure bar is attached across the frame on its open side. An elongated crotch-cradling panel of flexible material is removably attached between the closure bar and the frame on the opposite side of the walker. The person using the walker straddles the crotch-cradling panel which is adjustable in length for persons of different sizes. The legs of the walker are adjustable in height and terminate in removable or retractable casters. A person using the walker can either sit down on the seat or stand up in the walker (with appropriate adjustments being made in the length of the legs). In more severe cases of disability, the caster wheels are employed and the seat acts as a safety feature if the person using the walker should stumble or fall, since it will catch the person and prevent or minimize injury. For persons with less disability, the seat may be removed and the casters may be removed or retracted; so that the walker can be used in a conventional manner.
