Also known as underarm crutches or axillary crutches, are mobility aids that help individuals with lower limb injuries or disabilities. The main function of armpit crutches is to transfer weight from the legs to the upper body, allowing the user to walk without putting weight on their affected leg or foot. They consist of two upright posts that are attached to a crossbar which extends beneath the arm. Some general specifications include: - Height adjustment: Most armpit crutches can be adjusted in height to fit the user's specific measurements. - Weight capacity: It's important to choose crutches that can support the user's weight. - Material: Armpit crutches can be made from various materials such as aluminum or steel, which can affect their weight and durability.
