The height of the axilla crutches should be measured by standing in an upright position with appropriate supportive footwear. The underarm pad must fit under the armpit with two finger widths space above to ensure that no pressure is applied on the armpit while the crutches are in use. The adjustable handgrip can be set along the upright side of the crutches at a level where the protruding bone at the side of the wrist. The height of elbow crutches can be adjusted according to the user. The measurement is taken by lining up the handgrips with the wrist bone. Some models allow for the adjustment for the elbow cuff, which should cradle the forearm just below the elbow joint so that movement of the elbow is not impeded.
