Virtual arm proprioception error (VPE). Red diamonds present outcomes from the prosthesis user, excluded from the statistical analysis and solely used for representing the target population. a Shows the \(\hbox {VPE}_C\) for the baseline and the conditions without taking the baseline into account (Eq. 1). In b we visualize the VPE according to Eq. 2. Estimated means and standard errors from a post-hoc Tukey test are reported in a barplot format. The data was transformed via a quantile transformation for the statistical analysis, and its inverse transform was applied to the results presented
