Crutches and canes help patients walk without putting too much weight on their hind limbs. They also help improve balance, assist in walking, reduce the load on the lower limbs, transmit sensory cues, and enable maneuvering in places inaccessible to a wheelchair. Assistive devices are manufactured in many designs. Canes differ by material, handle shape, and base. There are three types of crutches; Axilla crutches, Elbow crutches, and Gutter crutches.
