Final answer:
Axillary crutches and Loftstrand crutches are used in the modified 3 point (bilateral crutches) PWB technique to provide support and stability while offloading weight from the affected leg.
Step-by-step explanation:
Axillary crutches and Loftstrand crutches are both types of assistive devices used for walking when a person has a lower limb injury or disability. In the modified 3 point (bilateral crutches) PWB (partial weight-bearing) technique, crutches are used to offload weight from the affected leg.
When using axillary crutches, the crutches are placed under the armpits and the handgrips are held. The patient bears partial weight on the affected leg, while the crutches provide support and stability.
Loftstrand crutches are forearm crutches that offer increased maneuverability and control. These have cuffs that go around the forearms, allowing the hands to be free. The patient holds onto the handgrips and bears partial weight on the affected leg.
