Stroke Upper Limb Rehabilitation With Robot Operators: a Synergistic Approach for Human-Robot Interaction and Rehabilitative Trials.

Brief Summary

In clinical scenario, clinical scales and kinematic analysis are usually used for the evaluation of patients. However, these methods are limited, since they may suffer from the lack of objectivity and sensitivity. Synergies go beyond pure kinematics and allow to directly understand the neural mechanisms underlying the motor impairment. Synergy analysis has been exploited for understanding physiological mechanisms in healthy subjects, but only few studies analyzed muscle synergies on patients during rehabilitation. In order to translate this methodology to the clinical practice, there is the need of comprehensive and structured studies. However, only few pilot studies are available that analyzed synergies during rehabilitation. Thus, in this study we aimed at filling this gap by analyzing synergies during human-robot interaction when using an end-effector robot and an exoskeleton robot and by assessing in detail the modifications of synergies after robotic rehabilitation.
