Abstract: A method for regularly and controllably flexing and extending the feet and the legs of a patient who is unable to move their legs and/or feet due to some physical or mental disorder. The oscillating footboard assembly is adjustable and adaptable to the users size. The oscillating footboard assembly is designed to regularly flex and extend (by a controllable amount of excursion and at a controllable frequency) the feet and the legs of a patient who is unable to move their legs and feet due to a physical ailment such as a stroke, coma, or paralysis. If the feet and legs are not regularly flexed and extended, they "freeze" in the extended position and it is extremely difficult and in some instances, impossible to resolve this problem. The frequency and the excursion of the oscillation may be adjustable on the assembly depending upon the needs of the patient. The assembly is easily and comfortably attachable to the patient through the use of booties or other means such as foot straps.
