dc.description.resumoBACKGROUND: Manual movements are affected by the index of difficulty of the task andhandedness. High index of difficulty and execution with the non-dominant hand can increase the mental workload.AIM:This study investigatedthe relation between the level of mental workload, the index of difficulty of the task,and handedness in manual movements. METHOD: Twenty-three right-handed male students (24.1 ± 4.3 years) participated in this study. The index of difficulty in the Grooved Pegboard task was manipulated by placing and removing the pegs and manipulation of handedness was made via right and left hand execution. Two mental workload metrics were obtained by electroencephalographic analysis: EEG-cognitive index, and EEG-workload index. RESULTS: The index of difficultyanalyses indicated lower movement time when removing the pegs (low index of difficulty) compared to placing the pegs (high index of difficulty). EEG-workload index was higher when placing the pegs than removing. The handedness analyses indicated lower movement time with the right hand compared to the left hand. However, similar levels of mental workload were found. CONCLUSION: Results suggest higher mental effort when index of difficultyis increased, but not when the left non-dominant hand is performing the task.pt_BR
