When I lost my leg I had to use a walker for the physical therapy rehabilitation process. Since I had to wait for the swelling to go down before I could get a prosthetic I had to have a walker in order to get around; this wasn't the safest thing because I had to hop while using it but for getting to the bathroom or moving from the bed to a chair it was easier than using a wheelchair. The Medline Folding Walker has two release buttons so the sides can be collapsed; this makes it completely portable so you can fit it in a vehicle with no problem. Once the sides are opened and the buttons pop out, it is locked in place and will not close while it is being used. When I was using this I had a lot of support from it and it really helped me regain my balance and confidence, two crucial elements that you need to work on during physical therapy so you can transition to a prosthetic with no balance problems. Most insurance companies will cover the cost of this whether it is a sort term rental or something that is given to the patient. Since I needed mine for more than three months the insurance company paid for it and it was mine to keep. I used this before I got my prosthetic as well as after I got it when I was still learning to walk again. One of the biggest perks to this over others that I tried was that the height could easily be adjusted. The spacer prongs that are used to lock the height in place are clearly marked too so if you have poor vision you won't have any problems adjusting this to the correct height.
