Background:
The da Vinci robot provides a sitting position and an armrest to decrease workload and increase dexterity. We investigated the surgeon's ergonomic behaviour by installing force sensors on the dV-Trainer® simulator's armrest to measure the 'armrest load' during the performance of simulated exercises.
Methods:
Five experts and 48 novices performed two robotic simulation exercises on the dV-Trainer. We calculated the armrest load and evaluated their armrest-using habits. Overall score and workspace range were evaluated automatically by the simulator and compared with armrest load.
Results:
Statistically significant differences exist for overall score, workspace range and armrest load between novices and experts.
Conclusion:
The armrest load score is a direct, sensitive measure for the ergonomic evaluation of a simulator's armrest use. This experience-dependent ergonomic difference between experts and novices (p = 0.007) highlights the importance of ergonomic training for novice robot users. Copyright © 2016 John Wiley & Sons, Ltd.
