Here are several types of frames that are used in rehabilitation:
Balkan frame
Metal construction above a bed, to which it is attached, providing for the suspension of a limb (e.g., after fracture), for the attachment of a pulley for exercise, or of a trapeze to facilitate the patient's moving about. It was reportedly used for the first time in a Dutch ambulance during the Balkan wars between 1908 and 1913.
Bradford frame
Rectangular frame made of gas pipe, covered with heavy canvas. Devised in 1890 by Boston orthopedic surgeon Edward H. Bradford (1848-1926). In a subsequent modification the canvas consisted of an upper and lower half, both movable, so that the patient could use a bedpan without changing position.
Foster® frame
Propietary name of a turning bed permitting easy change of a patient's position. Similar to the Stryker frame.
Stryker® frame
Proprietary name of a frame with a mattress that can be turned around its longitudinal axis, together with the patient. A second mattress is applied above the patient before turning, providing for the change from the supine to the prone position. Developed in 1939 by Homer H. Stryker (1894-1980), Michigan orthopedic surgeon.
Whitman frame
A variant of the Bradford frame but with curved sides.
