折叠步行者开始于20世纪50年代初出现。第一批美国专利于1953年颁发给英国Strotford的William Cribbes Robb，为一个名为“行走援助”的设备，该装置于1949年8月向英国专利局提交。^[1]Two variants with wheels were both awarded US patents in May 1957,^[2][3]并于1965年被欧洲辛辛那提，俄亥俄州的埃尔默F.采用第一个被称为“Walker”的非轮式设计。^[4]第一个类似于现代步行者的步行者于1970年由加利福尼亚州Van Nuys的Alfred A. Smith获得专利。
The basic design consists of a lightweight frame that is about waist high, approximately 12 inches (30 cm) deep and slightly wider than the user. Walkers are also available in other sizes such aspediatric（儿童）或bariatric(for 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.

根据使用它的人的强度和能力，折叠步行者的前两条腿可能或可能没有连接的轮子。它也很常见casterwheels or glides on the back legs of a walker with wheels on the front; additionallyfelt适用于腿部滑动的产品，如粘合剂脚，以及tennis balls孔切入它们以将它们放在腿上也用于表面上的表面，如硬木，环氧树脂和亚麻油地板。

该人与围墙的框架一起走，并且他们的手通过阻挡框架的侧面而提供额外的支持。传统上，送助行员并放置在用户面前的短距离。然后用户走向它并重复该过程。通过使用轮子和滑动，用户可以推动前方的助行器，而不是拾取它。这使得可以更容易使用助行器，因为它不要求用户使用他们的手臂抬起助行器。这对臂力很小的人有益。

沃克经常被那些从腿部或背部受伤恢复的人使用。它也常用于行走或轻度平衡问题的问题。

Also related is a hemi-walker, a walker about half the size of a traditional Folding Walker which is intended for use by persons whose dexterity is limited or non-existent in one hand or arm. These walkers are more stable than a quad cane (a cane with four points that touch the ground, as opposed to one), but are not recommended as highly as a traditional walker for those who can use it.
