These crutches rest under the arm (armpit ~ axilla), hence the name axillary crutches or underarm crutches. The body weight is transferred from the armpit to the floor and in this manner it can bear up to 80% of the body weight. The hands should grasp on the handles during walking but can be freed momentarily when standing, only if the hands need to be used and the entire body weight will not be rested on a single crutch during this time. It is more restrictive than nonaxillary crutches but does not require the same upper body strength and stability as nonaxillary crutches. However, users need to be aware of the dangers of using these crutches as ongoing pressure on the armpit area can cause compression of the nerves running through it. Therefore, crutch users are discouraged from resting their entire weight on the crutch for long periods like when standing.
