Aim: To fabricate a dynamic hand prosthesis and programming it to achieve functional movements at minimal cost.

Materials and Methods: The primary design of the prosthesis is done digitally and it is simulated using 3-D printing and milled with light weight polyurethane material. For incorporating the dynamic movements into the prosthesis, motors and electromotors (flex sensomotors) which work based on the hex code programming are used. These additives allow free movements and functional movements in the prosthesis. Using electromyography (EMG) neuromuscular coordination is simulated from the individual to the prosthesis. Electromyography works based on the recording of muscle amplitude in microamperes with two sensors. One sensor transmits the actual amplitude levels of healthier muscular movements while the other sensor intensifies or deranges the value based on the muscle threshold of the individual. The amplitude values are recorded in C code programming format which is human interfacing language. This is then compiled into the assembled programming for the ease of evaluation.

Results: Based on the design, functional and dynamic movements will be obtained in the hand prosthesis, which will improve the efficiency of rehabilitation thereby leading to future developments.

Conclusion: Functionally active hand prosthesis at minimal cost will pave way for rehabilitating patients and improving their quality of life.
