Quantitative Assessment of ADL: A Pilot Study of Upper Extremity Reaching Tasks

Figure 7

Sensitivity comparison of the five approaches with respect to the change in the severity of involuntary movements. A better evaluation technique is preferred to be sensitive to the small changes in the severity of involuntary movements and the change rate metric should be proportional to the change rate of severity. The blue and red lines show the improvement of metrics of the second and third severity levels with respect to the metric of the first trajectory computed with various approaches (refer to (12)). The orange lines are the regression lines of the corresponding metrics, showing the approximate improvement rate of each method. The value at the right bottom of each graph is the gradient of the regression line.
