UMD: Devices designed as a framework that combines a standard (nonwheeled) walker with an integral seat. These frameworks are typically a metal (some also include hard plastics) structure that frames the front and sides of users at waist level and is supported by three to five legs; they usually include supports (i.e., grips, platforms) for the hands and a seat (with or without a backrest) that allows a comfortable long-term sitting position. Nonwheeled walker/chairs may be foldable and/or adjust in height and/or width; they are intended for the permanent assistance of disabled (e.g., infirm) patients and/or for use during rehabilitation by patients who need to rest often while walking.
