<P> Recently, some studies demonstrated that exoskeletons could achieve a consistent 40% of tremor power reduction for all users, being able to attain a reduction ratio in the order of 80% tremor power in specific joints of users with severe tremor . In addition, the users reported that the exoskeleton did not affect their voluntary motion . These results indicate the feasibility of tremor suppression through biomechanical loading . </P> <P> The main drawbacks of this mechanical management of tremor are (1) the resulting bulky solutions, (2) the inefficiency in transmitting loads from the exoskeleton to the human musculo - skeletal system and (3) technological limitations in terms of actuator technologies . In this regard, current trends in this field are focused on the evaluation of the concept of biomechanical loading of tremor through selective Functional Electrical Stimulation (FES) based on a (Brain - to - Computer Interaction) BCI - driven detection of involuntary (tremor) motor activity . </P>
