Passive shoulder exoskeleton support partially mitigates fatigue-induced effects in overhead work

•Passive shoulder exoskeleton support does not affect the fatigue-induced decrease in overhead work precision performance.•Fatigue-induced decrease in performance was limited by changing shoulder kinematics and increasing muscle co-activation.•Passive shoulder exoskeleton support partially mitigated these fatigue-induced alterations.•The perceived workload of overhead work was not altered, despite activity reductions in muscles elevating the arm.
