Choosing the right prosthetic limb is an enormous decision. As you begin the journey to restored independence and greater mobility, you want to make sure that you’ve made the perfect choice based on your personal needs. Here’s what you need to know about both myoelectric and body-powered devices.

Myoelectric Prosthetics

A myoelectric prosthesis is powered by batteries and a motor to generate movements. Those motions are controlled by signals that are delivered from muscles attached to the limb. Whenever those muscles contract, they send a powerful electrical sign to electrodes, which are situated on your skin within the socket. In turn, the electrodes trigger the prosthetic leg or arm to move in whatever manner or direction you wish.

As technological advancements increase, users discover they have more options than ever before. Strength comes effortlessly, and it’s easy to use the device to perform many movements with ease. For example, squeezing a hand, gripping a doorknob, and kicking a leg all feel smooth and natural. However, these limbs cannot become wet, although some components may be resistant to moisture intrusion.

Body-Powered Prosthetics

A body-powered prosthesis uses harnesses, cables, or manual control systems to manage limb movement. The user uses this system or their body parts to control movements. Many people who have myoelectric devices rely on a body-powered device as a secondary option. The key with this option is that the user is in complete control of every movement, with no dependence on external sources of power. 

They are generally ideal for upper limbs, including above and below the elbow. If you have a passive arm, or one that requires a prosthetic limb but that you don’t use for everyday functioning, you might choose a body-powered device merely for its aesthetic appeal. This option is ideal for those with refined fine motor skills, as a great deal of precise control is necessary to operate them.
