Discover the differences between an electric prosthetic arm and a body-powered prosthetic arm to help you decide which type of arm prosthesis is best for your unique needs.

For arm amputees, being fitted for an upper limb prosthesis is an important first step to recovery and regaining independence. One decision patients need to make regarding a prosthetic arm, however, is between an electric or body-powered prosthesis. Understanding the primary differences between these options will help you make the right decision for your needs.

Understanding Electric Arm Prostheses



Electric prostheses, also commonly referred to as myoelectric prostheses, are controlled using electric signals that are actually created by your body’s muscles.

  • Specifically, these prosthetics work by using your existing muscles in your residual limb to control the functions of the prosthetic device itself


A sensor within the device is able to:

  • Obtain electrical signals from these muscles.
  • Translate those signals into movements.
  • Execute the demands properly.

These can be a great option for those who want a natural-looking prosthesis that utilizes existing nerves for functional use.

On the other hand, this upper limb prosthesis tends to be more expensive than a body-powered arm prosthesis, and it can take a longer adjustment period to become familiar to the body. Furthermore, the power source that operates the prosthesis does need to be charged regularly or may need battery replacement on occasion.

Understanding Body-Powered Arm Prostheses




A body-powered prosthesis relies on a system of cables or harnesses (along with manual controls, in many cases) to control the limb itself. Essentially, you operate and control the prosthetic arm using other parts of your body, such as your shoulders, elbows, or chest.

For many patients:

  • Body-powered prostheses are a practical option because they tend to be more affordable than myoelectric options and do not rely on an outside power source to operate.
  • Body-powered arm prostheses also make for an excellent secondary device, as they are great for use in more rugged environments and are ideal for getting specific tasks done.

It should be noted that this option typically does come with a sacrifice in fine motor skills and precision, so it is not the best option for everybody.

Which Option is Right For You?

Now that you have a better idea of the differences between these two types of prosthetic arms, you may be in a better position to decide which option is best for you. Still, there are some additional considerations worth keeping in mind to help you reach a decision, such as:

  • What you will mostly be using the prosthesis for.
  • Specific job duties or daily obligations.
  • Ability/willingness to charge a myoelectric device.
  • Ruggedness/durability required in the prosthesis.

You may also want to consider the specific level of your amputation, as some levels may make you a more suitable candidate for an electric prosthetic than others. These, along with other important factors, can be discussed with your prosthetist to ultimately make a sound decision. In some cases, it may make the most sense to have both types of prostheses:

  • One that you use the majority of the time.
  • A secondary option for certain tasks.

NOTE  : Hello, I Mahen Pitale, Below Elbow Prosthetic Users, I came across some websites while surfing the internet, which would be very helpful for people who (hand and leg amputees). And here is great information about modification and their parts. And you will be inspired by watching videos of some amputee. This will give you more convenience For this, I thank the company that created the website. This information should reach maximum amputees, it is for this, not to do any business. I request the wheelchair user ,amputees to please drive ,only after doing good practice.

Prosthetic Care - Wearing Prosthetics In The Summer

 Wearing Prosthetics In The Summer  Summer months are getting hotter each year. And if you're thinking of spending a day at the beach or lounging by the swimming pool, you are not exempt from some skin and prosthesis-related problems that are commonly prevalent during the hot and humid season. So, we'd like to help you keep your vacations fun by exercising a bit of caution to prevent discomfort and even jeopardizing your mobility. In this article, we’ll help you prepare to make the most out of the remaining hot season while also staying clear of season-related skin and prosthetic problems.   1. Heat-related illnesses Before we delve deeper into the most common skin and prosthetic problems you may encounter this summer, we feel that we must talk about season-related illness such as heat stroke (a.k.a. sunstroke), heat cramps, and heat exhaustion. Taking care of your body works best when it’s done from the inside out. The body is designed to cool itself down under extre

This Is the Most Amazing Biomimetic Anthropomorphic Robot Hand We've Ever Seen

Image
Image: Movement Control Laboratory/University of Washington With their hand, Xu and Todorov decided to start from scratch, duplicating the human hand mechanically in as accurate a way as possible. First, they laser scanned a human skeleton hand, and then 3D-printed artificial bones to match, which allowed them to duplicate the unfixed joint axes that we have, as Xu explains: “For example, the motion of our opposable thumb is relying on the complicated shape of the trapezium bone located at the carpometacarpal (CMC) joint. Due to the irregular shape of the trapezium bone, the exact locations of CMC joint axes are not fixed. Thus, none of the existing anthropomorphic robotic hands can restore the natural thumb motions with conventional mechanical joints that require fixed rotation axes. We 3D print artificial bones from the laser-scanned model of a cadaver skeleton hand and connect them with artificial finger joints whose range of motion, stiffness, and dynamic behaviors are very close t
