Myoelectric-controlled arm prostheses are externally powered prostheses, which means that they are not driven by the muscle strength of the patient, but with the aid of electric power. The word “Myo” is derived from Greek: mys (“muscle”)
A biochemical process generates electrical tension in the microvolt range every time a muscle contracts. This tension can be measured on the skin. This also applies to the muscles remaining after an amputation. With myoelectric arm prostheses, muscle tensions from the residual limb are usually read by two electrodes – small children start with one. The low myoelectrical impulses that lie in the microvolt range are then amplified and forwarded to the electronics of the prosthesis in the form of control signals. The great functional benefits of this prosthetic system have a decisive influence on rehabilitation results. Because myoelectric prosthesis also offer an appealing design as well as wearer comfort, they have become established as the standard.
ETD (Electronic Terminal Device)
Built for rugged, all-day use! Powerful, responsive, and precise. Water resistant and durable. Compatible with other systems
In this prosthetic hand, the most important fingers-index and middle fingers including thumb, are actively driven while ring and pinky fingers can act as a support to hold things from below and also support other fingers without much efforts; Thus, the Michelangelo hand prosthesis can do most of the tasks that you do with your natural hand and provide you with more freedom and confidence in your day to day life.
Myo-Electric Elbow. For upper-limb amputees, myoelectric-controlled prostheses offer the ultimate combination of function and natural appearance. Designed to mimic human anatomy and motion, electronic components are the closest alternative to an anatomical hand or arm. Thanks to constantly advancing technology, the latest prosthetic systems feature astonishing capabilities. Elbows that flex and extend with muscle signals so you can reach for a beverage and bring it to your lips.
