a Tremor amplitudes during DBS OFF and DBS ON, in terms of spectral power, at each recording site in one patient with tremor simultaneously in all body sites assessed. For graphical reasons the amplitude of tremor during DBS ON has been multiplied with 100. The data recorded are from when the same patient is standing with eyes open. b, Tremor peak frequency recorded at each site in the same patient and test condition as in (a)
