What Are Assistive Devices for Ambulation?

Ambulatory problems have a variety of roots, from muscle and joint damage to hyperobesity to paraplegia. For almost every type, there are devices designed to aid the user while walking and moving, and vary from simple to highly complex.

Cane/Crutches

• A one or two point system of support is a cheap and effective method when there is a weakness in one leg. It allows the arms and upper body to stand in for the weak or damaged limb.

Walker

• If both legs are too weak for satisfactory ambulation, the use of a 4-point walker may be required. This is a U-frame shaped device with an open back that allows support during both left and right leg steps.

Scooter/Motorized Cart

• For users with proper upper-body function, a motorized scooter is a good alternative. It can be mounted and dismounted fairly easily and reduces energy exertion compared to other alternatives.

Prosthetics

• Prosthetic limbs and braces can help those with certain mobility issues, and vary in price and function. Some allow fast running and do not resemble limbs, while others are more for aesthetics and slow walking.

Robotic Aids

• Newly developed robotic walking devices are an expensive but effective strategy for increasing ambulation. Argo Medical's ReWalk helps even those with no leg control, while other versions aid those with some remaining ambulatory function.
