User experience: Neuro-cognitive assessment experiment setup. A Example of a single episode showing the grid layout with a goal trajectory for subjects to track cursor with corresponding arm movements. B Subject wearing soft exosuit sitting in a chair facing the monitor displaying the experiment. The subject is wearing an EEG cap with 32 active gel-based electrodes for measuring neural activity. In this part of the experiment, the subject is controlling the cursor through the grid trajectory. C The Delsys Trigno EMG system with two electrodes from the QUATTRO sensor is used to record EMG data from biceps and triceps muscles respectively. The wrist position determined from the inverse kinematics from the IMU sensors is used to map the cursor position on the screen in the task. A full range of motion was required to move the cursor throughout the entire grid, with the arm needing to reach fully flexed and extended positions from medial to lateral-right side of the body
