The DEKA Arm System is the first prosthetic arm that performs multiple, simultaneous powered movements controlled by signals from Electromyogram (E.M.G.) electrodes. The E.M.G. electrodes detect electrical activity from contracting muscles near the attachment area of the prostheses. The electrodes then send those signals to a processor in the prosthesis that in turn translates them to movement or movements.
The arm can convert the signals in up to 10 powered movements and weighs as much as an adult arm. It can be configured for people with limb loss occurring at the shoulder joint, mid-upper arm, or mid-lower arm.
