Losing an arm or experiencing limb deficiency due to an accident can be devastating. It's a challenge to adjust to such a life-changing experience. Upper-limb prosthetics have made remarkable progress over the past few decades. It has provided the opportunity for people to restore their abilities and empower them to lead productive lives. There are a variety of upper-limb prosthetics available in the market, each with its advantages and disadvantages.

Here's a breakdown of the different types of upper-limb prosthetics.

1. Body-Powered Prosthetics

Body-powered prosthetics work on the principle of cables and pulleys, and these are the oldest types of prosthetics. They are operated by a cable that connects the prosthetic arm to the body's remaining muscles. This prosthetic can be controlled by attaching and releasing a cable connected to the opposite shoulder. The prosthetic user pulls the cable to move the arm and releases it to make the arm come back to its initial position.

One of the advantages of body-powered prosthetics is durability. They are comparatively more durable than any other type of prosthetic. They also produce enough force for everyday activities like lifting things and grasping objects. However, body-powered prosthetics require constant repositioning and adjustment, making them cumbersome to use sometimes.

2. Myoelectric Prosthetics

Myoelectric prosthetics work on the principle of an electrical signal; they use an external sensor that detects muscle activity. The prosthetic arm is operated using electrodes on the surface of the skin. The electrodes detect the signals produced by the muscles and send a signal to operate the prosthetic. This prosthetic is usually battery-operated and can be operated by the users using buttons, switches, or sensors.

One of the advantages of myoelectric prosthetics is that they are easy to use and provide more natural-looking movements than body-powered prosthetics. They also allow greater maneuverability, precision in movements, and more control. One disadvantage is that they require regular maintenance and need a rechargeable battery.

3. Hybrid-Prosthetics

Hybrid prosthetics work by combining the benefits of both body-powered and myoelectric prosthetics. They come with an external power source that enables the prosthetic to work with the body's muscle signals and the body's mechanical pull/push signals. The prosthetic combines these two types of signals to create fluid motion.

One advantage of hybrid prosthetic is that it reduces the effort it takes to operate them when compared to the traditional body-powered prosthetic. They are also very durable and provide users with natural movement and more significant control. Despite this, they are often heavy and bulkier, which can be limiting for some users.

4. Passive Prosthetics

Passive prosthetics are designed to mimic the appearance of a natural arm, shoulder, or hand. The purpose of these prosthetics is to restore balance and symmetry to the body. Passive prosthetics are built to look like an actual limb but are not motorized or electronic. They are attached to the body, and they make it look as though the user has an actual limb.

One advantage of passive prosthetics is the cosmetic appeal; it offers users the chance to feel a sense of normalcy as it helps them fit into their surroundings better. Passive prosthetics are also lightweight and require little to no maintenance. However, they do not have the same functionality as other types of prosthetics. They are simply cosmetic, and they do not enable the user to complete everyday tasks that require physical assistance.
