Teleoperated Bilateral-Arm Rehabilitation With Alex Rehab Station

In this paper we aim at demonstrating the feasibility of a bilateral training protocol supported by a dual arm exoskeleton, ALEx-RS. Three subjects performed the same reaching task in three conditions: with and without the exoskeleton, and in the bilateral mode. EMG data recorded during the experimental sessions showed that ALEx-RS features a high level of transparency and all subjects easily accomplished the bilateral task in an intuitive way. These findings demonstrated the suitability of ALEx-RS for being applied in a rehabilitation protocol in which also bilateral strategies are employed.
