The main aim of the project is to evaluate a novel upper body exoskeleton during simulated industrial work. In this stage of the project, a study analysing the physical and mental load during occupational work will be carried out. High risk tasks will be identified in the field and simulated in lab-setting to analyse physical and mental load using physiological and biomechanical data.These will include, but will not be limited to, non-ergonomic postures, for example performing operations above the head or reaching in front of, to the side of, or behind the body; flexing the arms for extended periods of time; and bending or twisting the torso to lift an object from low or distant locations. Important items to assess in this task are the frequency and duration of tasks and activities, lifting characteristics, perceived physical effort and work-induced fatigue.

| Industrial work | Behavioral | Subjects perform simulated industrial work in lab setting. The industrial task exists of a physical component and a cognitive component. Physical load is measured by questionnaires and basic physiological measurements (e.g. heart rate). Mental fatigue will be determined by questionnaires and a cognitive stroop task before and after the trial. |
| Measure | Description | Time Frame |
|---|---|---|
| EEG: change in power spectral density (change in mental fatigue: physiological component) | The power of different frequency bands during a cognitive Stroop task will be compared PRE vs POST 90 minute task and differences between different tasks will be analysed. | Measuring EEG during Stroop tasks (10 minutes) before and after each 90 minute task |
