Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
EEG: change in power spectral density (change in mental fatigue: physiological component)Measuring EEG during Stroop tasks (10 minutes) before and after each 90 minute task

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.

Secondary Outcome Measures
NameTimeMethod
EEG: changes in event related potentials during cognitive Stroop task (change in mental fatigue: physiological component)Measuring EEG during Stroop tasks (10 minutes) before and after each 90 minute task

Event related potentials during cognitive Stroop task will be compared PRE vs POST 90 minute task and differences between different tasks will be analysed.

Change in mental fatigue (subjective component)Before and after each 90 minute task subjective questionnaire will be filled out

Questionnaire (sRPE) before and after performing each 90 min task

Change in mental fatigue (behavioral component: part 1)Measuring reaction time during Stroop tasks (10 minutes) before and after each 90 minute task

Reaction time during cognitive stroop task

Change in mental fatigue (behavioral component: part 2)Measuring accuracy during Stroop tasks (10 minutes) before and after each 90 minute task

Accuracy time during cognitive stroop task
