Real-time robustness evaluation of regression based myoelectric control against arm position change and donning/doffing - Fig 7

<p><b>(a) Online performance estimated according to the sequence of online evaluation runs for each performance metric (run 10–33)</b>. Note that due to the subject-specific randomization different combinations of training and testing arm positions were averaged, and thus the general impact of donning/doffing and growing user-experience on control performance can be observed. (b) Comparison of the mean performance estimated before and after donning/doffing (*<i>p</i> < 0.05 and ***<i>p</i> < 0.001). The error bars represent the standard deviations of the mean performance values of the thirteen able-bodied subjects.</p>
