Partial hand loss comprises about 90 percent of all upper extremity amputations and may involve the loss of one or more digits. Prostheses for this level of limb absence have historically been simple opposition designs that utilize movements from the person's remaining thumb or fingers for grasping. We investigated the finger design and kinematics, mechanical joint coupling, and actuation methods of these commercial prosthetic hands. The empirical findings are supplemented with a compilation of published data on both commercial and prototype research prosthetic hands

Typical kinematic designs of the commercially available prosthetic fingers include two phalanges where the distal interphalangeal (DIP) joint is fixed, and the metacarpal phalangeal (MCP) and proximal interphalangeal (PIP) joints are free to rotate The overall design for this prosthetic hand was treated as an investigation of feasibility. After performing the necessary background research and studying the available products on the market, it was determined that constructing an entire prosthetic arm was not necessary. A prosthetic hand would be much more realistic to design any limited. In hand prosthesis design, the important characteristics that directly affect hand performance are the ability to grasp various type of objects, grasping force that provides stability for holding. Today, there are many prosthetic hand designs that offer a wider range of mobility and also provide a more natural appearance.
