Forequarter and Shoulder Disarticulation
In circumstances where an amputation is required at the shoulder or forequarter level, function is difficult to restore. In the past, due to a combination of factors: weight of prosthetic components and decreased function due to multiple joints, a purely cosmetic prosthesis is used to improve body appearance and to improve body balance.At present, however, a myoelectric arm offer amputees with forequarter and shoulder disarticulation a more realistic solution. The myoelectric arm works under the influence of electric signals extracted from skin surface. These signals are used to run various motors which enable the patient to grip and move limbs in an efficient manner.
