5.4 Types of walkers

Standard walker: has four legs with ferrule (no mobile base) (Figure 7A). The user requires strength and grip power to lift the entire frame forward during ambulation.

Wheeled walker: the design is similar to the standard walker but the ferrules are replaced by wheels (Figure 7B). The number of wheels depends on the strength and stability of the user. The user only needs strength tilt the ambulatory device move forward. The wheeled walker can be 2-wheeled walker or 4-wheeled walker. Some design can come in with three legs instead of four and the three legs will be wheeled. Some walkers are design with hand brake for stability. The wheeled walker is better than the standard walker because the user require less energy to move the device forward. However, it is better prescribed for stable users, who can control the walker reasonably. Another disadvantage of 2-wheeled and standard walker is that they cannot be swivel by user when turning, they need to be carried but the 4 wheeled walker and 3-wheeled walker can be swivel. There are two different

with about four legs or less in which the user holds the handle bars at wrist height and place the device in front during movement (Figure 7). It has horizontal bars on vertical posts for adjustment and folding. It has a permanent hand grip and rubber ferrules. The horizontal bars are about 18 inches apart to fit the body of the user while the height can be adjusted by the vertical posts. Adult walker height is between 32 and 37 inches (81–92 cm). Pediatric walkers are also available with

The parts that formed the walker include handgrip, ferrule (or wheels), open and close button (for folding or collapsing the walker), push buttons (for adjustment of the height of the walker). The horizontal bars and vertical posts are made of different materials such as wood, hard plastic, stainless steel, aluminum steel and iron. The material used to manufacture the walker determines the weight,
