today include a number of combinations for canes, crutches, and forearm crutches. These crutches have bands that encircle the forearms and handles for the patient to hold and rest their hands on to support the body weight. The forearm crutch typically gives a user the support of the cane but with additional forearm support to assist in mobility. The forearm portion helps increase balance, lateral stability and also reduces the load on the wrist. Walkers A walker (also known as a Zimmer frame) is the most stable walking aid and consists of a freestanding metal framework with three or more points of contact which the user places in front of them and then grips during movement. The points of contact may be either fixed rubber ferrules as with crutches and canes, or wheels, or a combination of both. Wheeled walkers are also known as rollators. Many of these walkers also come with an inbuilt seat so that the user may rest during use and with metal pouches to carry personal belongings. Walker cane hybrid A walker cane hybrid was introduced in 2012 designed to bridge the gap between a cane and a walker. The hybrid has two legs which provide lateral (side-to-side) support which a cane does not. It can be used with two hands in front of the user, similar to a walker, and provides an increased level of support compared with a cane. It can be adjusted for use with either one or two hands, at the front and at the side, as well as a stair climbing assistant. The hybrid is not designed to replace a walker which normally has four legs and provides 4-way support using both hands. Gait trainers Another device to assist walking that has entered the market in recent years is the gait trainer. This is a mobility aid that is more supportive than the standard walker. It typically offers support that assists weight-bearing and balance. The accessories or product parts that attach to the product frame provide unweighting support and postural alignment to enable walking practice. Seated walking scooter The Walk Aid Scooter allows a user with normal balance and foot, knee or hip conditions to unload the lower extremities. The two-wheeled scooter has a bicycle-type seat and handlebars, and is manually propelled with one or both feet like a balance bicycle. This walking aid scooter provides more support than a cane
