This paper presents an implementation of a practical and low-cost hardware-based
control system for multifunctional myoelectric hand prostheses. The model
utilizes a mode-switching technique in order to voluntarily control the operation
of a dual-mode prosthetic device in two degrees of freedom : grasp/release and
pronation / supination. This system was designed specifically to cater to the
increasing needs of patients in developing countries, where myoelectric
prostheses are scarce and extremely expensive. The design relied entirely on
locally-available commercial components and aimed at allowing small prosthetics
producers the freedom to utilize and modify the design according to their
clients' preferences and requirements. Evaluation tests revealed excellent
control and ability to execute basic hand and wrist functions even with short
training periods, although results varied with the underlying level of muscular activity.
