Automatic assessment of time execution (left) and smoothness of movement (right) over different directions in the vertical plane. The first and second radial plots show the difference for each direction of the first and the last rehabilitation sessions in terms of Execution Time and Smoothness Index respectively averaged over patients. For each direction ‘*’ and ‘**’ show significant differences (paired t-test) at p < 0.05 and p < 0.01 respectively
