| dc.description | Ever since the concept of myoelectric prosthetics first became a reality there has been a continuing and incremental effort aimed at maximizing the number of degrees of freedom in which the device may be operated, while simultaneously minimizing the number of electrode muscle sites required to accomplish this task. Berger and Huppert where among the first to employ an electrical signal for the control of a myoelectric prosthesis.1 Shortly after, in 1966, a three-state (rest, open, and close) single-site control concept was introduced by Dorcas and Scott in which each degree of freedom was controlled by a single muscle site.2 During approximately the same period various other strategies based on multistate myoelectric control were also introduced; these systems required multiple control sites for multifunctional control.3,4 Paciga et al.5 and Richard et al.6 studied the feasibility of multi-state (up to five-state) myoelectric control systems. The user error was found to significantly increase when attempting to control more than three states from a single channel. | |
| dc.description.abstract | 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.
