While there are certainly some different features and aesthetics based on the brand and model of the walker you choose, they are generally very similar. They will have four legs, along with comfortable grips. Some may actually have wheels on the front legs.
How walkers work
Those who are going to use a walker need to make sure they do so safely. They are simple devices, but they do take some getting used to when first using them. The walker acts as extra support ensuring the patient doesn't fall. When first learning to use the device, it's important to practice the basics first, such as standing up and sitting down. Walk slowly to get accustomed to moving the walker, and then learn how to turn around in the device. It will usually take two to three steps to make a 180 degree turn. Do not try to move too quickly, and do not twist your back while you are making the turn.
Walkers are relatively simple devices, but they can provide an extraordinary amount of help to those who use them. Many people, whether they are elderly and have problems with mobility, or they are recovering from an injury, find walking to be difficult. It can take a lot of energy out of them, and they may have a fear of falling. Using a walker will help to negate these issues and return some mobility to the person's life.
