Boxplots of path length of Z in each block in the wheelchair condition (days 1 and 2) and in the bucket condition (days 3 and 4). Each testing session was separated by 1 week. Testing sessions consisted of 24 trials whereas training sessions consisted of 20 trials each. Each day consisted of a pre-test, 4 training blocks, a mid-test, 4 more training blocks and a post-test. The pre-test of the bucket condition on day 3 is not displayed because of missing data. The Y-axis has been truncated to avoid 7 extreme outliers
