r calculated between sensor 1 and sensors 2, 3 and 4 during exercise 3. Parameter $r_{12}$ is the average of r calculated between the signals $S_{\omega 1}$ and $S_{\omega 2}$ over all the movements that each volunteer performed to complete the exercise 3; $\left({\sigma }_{12}\right)$ is the standard deviation of these calculations. $r_{13}\left({\sigma }_{13}\right)$, gives the same information as previous column, but correlation was performed between sensors 1 and 3. $r_{14}\left({\sigma }_{14}\right),$ In the same way as the previous two, brings the information regarding correlation between sensor 1 and 4. Finally, $r_{23}\left({\sigma }_{23}\right)$ shows behavior of the combination thumb-index (for exercise 3, it brings information regarding tweezers manipulation).
