Figure 2
The absolute (A) and relative (B) power of the angular velocity in 2 s windows as a function of the mean frequency in the 3 frequency sub-bands, delineated by dashed lines: the LF band (<3.5 Hz), the pathological tremor (TF) band (3.5-7.5 Hz), and the normal physiological tremor frequency (HF) band (7.5-15 Hz). Each window was classified as a tremor (closed markers) or non-tremor (open markers) window. Tests were performed with auditory cues with different frequencies: 1.6 Hz (blue markers), 3.2 Hz (green markers), and 4.8 Hz (red markers). Each data marker represents a single extremity in individual patients at a particular DBS setting.
