Assisted devices help a person with leg/knee injuries to be able to move about with a bit of comfort. In case you are looking to go through surgery or are recovering from injuries, the following are some devices that will help enable you to move around easier:
 

Grab Bars
This is a bar which you can attach to your shower or bathtub for assistance when you want to support yourself with something when you are entering or getting out of your bathtub. The grab bar can also be placed along your faucet wall so you can hang on to it when you want to lean over and turn your water on or off. The other can be placed horizontally on the back wall to help you rise after sitting on your bathtub. You need to ensure that the grab bars have been screwed securely on your wall so they may be able to handle your weight.

Knee Scooter
Knee scooters are associated to crutches because they are being used to replace conventional crutches. Knee scooters are easier to move around with and more comfortable than crutches. They are being used mainly for those suffering from arthritis, a condition that makes it difficult to move around with crutches.

Knee Walker
Roll about walkers enable you get rid of the weight from your lower body so that you can be able to heal or await your surgery comfortably. This walker helps you roll about by supporting your leg or foot in order to prevent any more damage. A steerable walker or knee scooter is a substitute for crutches since crutches can lead to further injury. Some of the best knee walkers in the industry are available from Knee Rover, who also provides an all-terrain knee walker.

Knee Caddy
You can use a knee caddy while your hands are free enabling you to go about your daily activities in comfort. These devices are most appropriate for someone with ankle, foot or lower leg injuries since it reliefs the weight of your lower body in order to make recovery easier.

Cane
If you have a weak leg or unsteady feet, a cane offers support and balance for your body. A cane should be the right length to prevent back and shoulder pain. The ideal length of a cane is the point where you wear your wrist watch while standing with arms beside you. You should hold your cane on the strong side of your body. If you are suffering from arthritis of the hip, use the cane on your opposite hand to get rid of pressure on the hip. Ensure you move your cane and weak leg together.

Assisted devices are indispensable if you are looking to have surgery on your leg or are recovering from a major or minor leg injury. Moreover, they are a great assistance for those who have to cope with conditions such as arthritis.
