Upper limb amputations often have a significant impact on functionality and quality of life, limiting work, leisure, and daily activities. During rehabilitation, the amputee’s main expectation is the use of a prosthesis, particularly its functionality and appearance. Prosthetic devices provided by the Brazilian Unified Health System (SUS) are typically mechanical and offer limited functionality. Myoelectric prostheses, which are capable of restoring pincer movements through electrodes, represent a more advanced alternative, but their high cost and unavailability within SUS restrict access. Considering the functional impact of upper limb amputation and the limited prosthetic options available through public health services, the objective of this study was to describe the development process of a low-cost myoelectric prosthesis and to evaluate its functionality. The study was divided into two phases: (1) prosthesis development, and (2) clinical testing with six non-amputated individuals (control group) and two amputees (test group). The Pick and Place (PAP) test and the Quebec User Evaluation of Satisfaction with Assistive Technology were employed. Preliminary results showed that the developed prosthesis was functional for the proposed tasks involving grasping, reaching, and object manipulation. The prosthesis demonstrated safety and stability, offering users confidence and efficiency during use.
