High Quality Content by WIKIPEDIA articles! A walker or walking frame is a tool for disabled or elderly people who need additional support to maintain balance or stability while walking. The British English common equivalent term for a walker is Zimmer frame - from Zimmer Holdings, a major manufacturer of such devices and joint replacement parts.The modern walker was patented by Andrejs Muiza who immigrated to the United States (Nashville, TN) from Latvia following World War II. The basic design consists of a frame that is about waist high, approximately twelve inches deep and slightly wider than the user. Walkers are also available in other sizes such as Pediatric (for children: see baby walker) or Bariatric (for overweight or obese persons). Modern walkers are height adjustable and should be set at a height that is comfortable for the user, but will allow the user to maintain a slight bend in their arms. This bend is needed to allow for proper blood circulation through the arms as the walker is used. The front two legs of the walker may or may not have wheels attached depending on the strength and abilities of the person using it.
