NeuroLab refers to an experimental platform designed to enhance studies in human movement and neuro-motor control. The platform comprises a robotic exoskeleton and some other stand-alone devices. All of these components have communication capabilities integrated in hardware and can work cooperatively taking advantage of a networked architecture. A set of experiments have been conducted with NeuroLab. The objective of the trials was to use mechanical perturbations to identify the viscous-elastic properties in human elbow joint and to correlate such mechanical impedance with the electromyographic information of muscles associated to the joint, during a postural task and in a rest position. In each condition, a pseudo-random torque perturbation was applied directly to the arm and to the forearm by mean of an upper limb powered exoskeleton. The angular kinematics (velocity and position), kinetics (torque) and the muscular activation patterns (EMG) in the two main muscles (biceps and triceps brachii) intervening in the elbow flexion-extension movement were recorded.
