From: Human arm weight compensation in rehabilitation robotics: efficacy of three distinct methods
Confidence intervals of the Mean effort index (MEI) results of the methods over all subjects and poses: The plot shows the MEI mean in 95% confidence intervals for the three arm weight compensation methods summarized for all participants and poses. Method Average: 0.435±0.035 MEI, method Full: 0.491±0.055 MEI, and method Equilibrium: 0.353±0.041 MEI. Dunnet’s multiple comparison revealed that method Equilibrium is highly significantly better as method Average (p<0.001) and method Full (p<0.001) respectively
