Upper Extremity

Founder, Mr. Johnson Yeh studies hand repair at Otto Bock laboratory in Germany

After a below elbow amputation, a portion of the wrist flexion and extensor muscles still remain in the arm. When these muscles are contracted, a very low voltage potential is generated and picked up on the skin surface by electrodes. An electronic amplification system housed in the electrode amplifies this signal and activates a circuit for the electric motor in the hand. The motor drives a miniature gear system which in turn moves the finger and thumb. The Myobock System combines optimum cosmetic and physiological control with a strong gripping force and operating speed. The myo electric prosthesis at present is the most modern way to care for a below elbow amputee, it combines the best cosmetic effect with superior prehension power and speed. It works almost noiselessly and requires only minimum effort from the remaining muscles.
