This study aimed to evaluate the cognitive workload and muscular demands of a passive shoulder exoskeleton. Twenty-six participants were involved in completing four simulated overhead construction tasks in With and No Exo conditions. We used the NASA-TLX to determine their cognitive workload scores and utilized surface electromyography (EMG) to capture the muscle activities of the Anterior Deltoid, Lateral Deltoid and Triceps muscles. Mean and standard deviation were used to present the average cognitive load and EMG scores. The Wilcoxon Signed Rank Test and Mann-Whitney U Test were conducted to determine statistical differences between means with a P value of
