“…"Peaks metric" used as (-ve) number of peaks to makes increment of the peaks metric in lin e wit h increment of the smoothness [6,23,15,20,21,28]. The distance travelled and the number o f data has normalized the number of peaks in the velocity profile [25,26,32] T he metric of movement smoothness can be evaluated by dividing the mean speed wit h th e p ea k speed [7,14,15,21,23,24,28]. T ime to Peak Velocity (T PV) T he T PV defined as the percentage of the time to reach the peak velocity o f t he p atients' h and movement [26].…”
