Fig. 3

Parkinsonian tremor peaks detected in anteroposterior direction in a patient standing with eyes closed and DBS OFF. Noteworthy, both the force platform and 3D motion capture system detected tremor peaks, and the 3D motion capture system detected tremor peaks at all four multi-segmental body positions of an identical frequency. Both assessment methods record physical representations of the tremor, though of different entity, i.e., as additional torque towards the support surface or as additional body movements within a specific frequency range. The power spectrums have been moved vertically in the figures to better display the individual recordings
