MF-Industrial Work

Details and patient eligibility

About

To investigate the effect of mental fatigue on industrial work performance, biomechanical determinants, (electro-)(psycho-) physiological measures and physical ergonomics. Additionally, the current project wants to evaluate whether or not the Laevo exoskeleton influences the aforementioned parameters when mental fatigue is acutely induced.

12 participants in 4 patient groups, including a placebo group

Mental fatigue - No Robot

Experimental group

Description:

During a 15 minute trial, the participant will relocate a box of 5 kilograms between ground level and shoulder height. During this task, the participants are asked to perform the serial seven task, continuously subtracting seven from a given number between 900 and 950. Afterwards, the participant will perform a 60- minute Stroop task and is asked to repeat this abovementioned physical dual-task.

Treatment:

Other: Mental fatigue (Stroop task)

Mental fatigue - Exoskeleton

Experimental group

Description:

During a 15 minute trial, the participant will wear the Laevo exoskeleton and will relocate a box of 5 kilograms between ground level and shoulder height. During this task, the participants are asked to perform the serial seven task, continuously subtracting seven from a given number between 900 and 950. Afterwards, the participant will perform a 60- minute Stroop task and is asked to repeat this abovementioned physical dual-task.

Treatment:

Other: Mental fatigue (Stroop task)

No Mental fatigue - No Robot

Placebo Comparator group

Description:

During a 15 minute trial, the participant will relocate a box of 5 kilograms between ground level and shoulder height. During this task, the participants are asked to perform the serial seven task, continuously subtracting seven from a given number between 900 and 950. Afterwards, the participant will watch a 60- minute neutral documentary and is asked to repeat this abovementioned physical dual-task.

Treatment:

Other: Control (documentary)
