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

(a) Online performance estimated according to the sequence of online evaluation runs for each performance metric (run 10–33). 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 (*p < 0.05 and ***p < 0.001). The error bars represent the standard deviations of the mean performance values of the thirteen able-bodied subjects.
