Body-Powered Prosthetics

Body-powered prosthetics are mechanical devices operated by the movements of the user's body, typically using a system of cables, harnesses, and joints to translate motion from one part of the body to control and move the prosthesis. Here's an overview of their types, uses, and companies that manufacture them:

Types and Uses:

  1. Hook Prosthetics:

    • Uses: Primarily for individuals with upper limb amputations. Hooks are functional for gripping and holding objects.

    • Features: They are durable, lightweight, and can be covered with a cosmetic glove.

  2. Prosthetic Hands:

    • Uses: Offer a more natural appearance and are used for various daily activities, including gripping and holding.

    • Features: They may have a limited range of motion compared to hooks but are preferred for their aesthetic resemblance to a natural hand.

  3. Articulating Prosthetic Fingers:

    • Uses: For partial hand amputations, these prosthetics replace missing fingers.

    • Features: They can move and grip in coordination with the remaining part of the hand, offering more precise control.

  4. Elbow Units:

    • Uses: For those with upper arm amputations, these units replace the elbow joint.

    • Features: They allow for bending and straightening, often with locking positions for stability during different tasks.

  5. Shoulder Disarticulation Prosthetics:

    • Uses: For individuals with an amputation at the shoulder, these prosthetics replace the entire arm.

    • Features: They are typically more complex, incorporating systems to control the elbow, wrist, and hand.
