The number of successfully transferred pins for intervention and control groups (boxplots), and the subject with dysmelia (black dots) in pre- and posttest with the real prosthesis. The boxplots depict median (horizontal line), interquartile range (box), min and max values (whiskers), and outliers (cross). The horizontal bars indicate statistically significant difference (*, p < 0.05). IG and CG stand for intervention and control group, while PRE and POST refer to pre- and posttest, respectively. The performance of the intervention group increased significantly after the training, outperforming the control group in the posttest
