Forearm crutches are just what the name implies—they have a cuff that fits around your forearm and handles for your hands that allow you to maneuver yourself from place to place safely and with a lot less discomfort than there would be using the old-style crutches.
Forearm crutches are smaller, made of lightweight aluminum, are comfortable, and safe to use.
Forearm crutches give you a better sense of control over your body and your movements and are just safer and easier no matter how you look at it.
So if you find yourself in need of crutches for any reason, make sure you opt for forearm crutches. You will be glad you did.
