Incorporates either a passive, cable operated, or external powered elbow to assist with positioning of the terminal device. Requires more body motion for control of cable operated devices than the transradial level, therefore some patients may require an external powered terminal device for optimum function.

A “Hybrid” device, a passive or cable operated elbow combined with an external powered terminal device, provides a lightweight device with high function. Most often suspension is achieved by the use of a harness system, although suction and gel liners can be used as an auxiliary suspension.
