A walker is a movable device used to help a person walk. It is lightweight, made of metal tubing, and has four widely placed, sturdy legs shaped in a "U" with the open end next to the person holding it. The patient holds onto the walker, takes a step into the "U", then moves the walker forward and takes another step. The walker can be collapsed into itself for easy storage and transportability, so that the person can take it with him or her into a car, onto a bus, etc. The walker is frequently given to patients recovering from a |stroke|, hip surgery, or other condition which might lessen the patient's ability to walk unaided. With the walker the patient has considerably more freedom because the walker is so stable.
