Experimental setting. a Participant setting; b, c experiment timeline for Task (movement) and rest trials. The red dotted line represents the activation profile required to correctly complete the task as for the target muscle (ED for Ext and FD for Grasp) and Rest. In addition to EEG and EMG data, the recording included also kinematic data. They were collected at 100 Hz by means of 8 IMUs (MTw Awinda, Xsens Technologies, The Netherlands). The IMUs were placed by a double-sided medical tape on the following anatomical points: hand, mid forearm, mid arm of both upper limbs, over the clavicular notch and at the lumbar vertebrae level. Such data were not included in this study
