Most wheelchairs come standard with metal handrims that clients can utilize to self propel. However, sometimes metal handrims are not optimal. For instance, in climates where weather reaches low temperatures, the metal rims often become very cold to touch. Furthermore, metal handrims possess a surface that is smooth, thus making it hard to grasp to spin the wheel.
Fortunately, there exist plastic and foam handrims. These increase the surface area and vary in treads available to facilitate grasping of the handrim. With a good grasp, the client is better able to self propel. However, these type of handrims add an additional width to the wheelchair and may make traversing through doors and tight spaces difficult.
