Figure 8From: Quantitative assessment of parkinsonian bradykinesia based on an inertial measurement unitTen-second hand grasps and their PSD figures. a 72 year old control subject; b 82 year old PD patient with tremor and bradykinesia, UPDRS bradykinesia score D = 1; c 86 year old PD patient, UPDRS bradykinesia score D = 3. The peak powers in the figure were calculated based on the power estimation around the dominant frequency and with a weighted scale.Back to article page
