Exoskeleton prototype. The exoskeleton is composed of three parts: the metallic structure, the elbow joint (Joint 1), and the forearm joint (Joint 2). The metallic structure is an off-the-shelf Breg T-Scope Elbow brace, which has telescoping struts to allow maximum customization of fit. The Breg T-Scope Elbow brace also provides an extension and flexion control from 10° to 120°. Moreover, for safety purposes, it has an adjustable mechanical lockout. Besides, the Breg T-Scope Elbow brace has four straps: two for the forearm and two for the upper arm. These straps ensure full attachment between the brace and the user’s arm.
