Product Overview
Myoelectric Technology
Arm Dynamics patient testing electrode placement for myoelectric prosthesis
Arm Dynamics patient and clinician testing myoelectric pickup sites
Myoelectric upper limb technologies use electrical signals generated by muscles in the residual limb to control the movements of a prosthesis. When the user contracts certain muscles, surface electrodes in the socket detect the muscle signals and send them to a controller, which triggers tiny, battery-powered motors to move the fingers, hand, wrist or elbow.
The advantages of myoelectric prostheses include more intuitive control of the prosthesis, increased grip strength, access to multiple grip patterns and more natural hand movements.
Myoelectric technologies are available for all levels of upper limb loss.
-Myoelectric Fingers: Electric finger solutions for those with finger amputations consist of individually-powered prosthetic fingers that can bend, touch, pick up and point. Electric finger solutions are custom built to replace any missing fingers and work in harmony with any remaining fingers.
-Myoelectric Hands: Fully articulating myoelectric hands are available from a variety of manufacturers in multiple sizes and configurations. Some of the most popular devices are:
The Taska Hand
The bebionic
The i-limb
The Michelangelo Hand
-Myoelectric Arms and Elbows:
Dynamic Arm Elbow: The DynamicArm Elbow prosthesis incorporates a powerful electric motor in combination with the Vario Drive clutch to help with flexion and extension of the elbow and can hold up to 11 pounds. It pairs with the SensorHand Speed prosthetic hand and features an Automatic Forearm Balance system that spares energy and makes the prothesis look and feel more natural.
Utah Arm: The sturdy Utah 3 provides simultaneous electronic control of the hand and elbow, effortless extension of the elbow, a free-swing mode, optional wrist rotation, and is available in jet black, tan and brown.
The Utah Arm 3+ offers the same features as the Utah 3 with the addition of the "Dual Lock System," silent free-swing and Bluetooth wireless communication.
