Impact of a passive upper-body exoskeleton on muscular activity and precision in overhead single and dual tasks: an explorative randomized crossover study.

For the conditions of single-task pre-fatigue without exoskeleton and dual-task pre-fatigue with exoskeleton, the results showed barely insignificant values. 3.2 Speed-accuracy trade-off management with and without exoskeleton according to the fatigue condition (Fitts’ task) Figure 3 shows the differences between the fatigue and the IDs (Fitts’ task) separately for the conditions with and without the exoskeleton.
