Times for completing the clothespin relocation test per participant. Lower time scores indicate better performance. The number written above each bar indicates how many pins were dropped (maximum = 6). Participants in the game group are in solid colour (P3, P6), while participants in the conventional group are shaded (P2, P5). Baseline was conducted before training using the participants’ own DC controlled prosthesis. Pre- and post-tests were conducted using the Michelangelo hand controlled with ML. In the pre-test all participants used one DoF and in the post-test participants used two DoFs. Participant P3 was unable to grasp any of the yellow clothespins at the pre-test, so the time is for the red clothespins only
