For each patient the age (yrs), the sex (m/f), the predominantly affected body side (right/left) are specified besides the time since disease onset (yrs), the time since the implantation of the DBS devise and the manufacturer. In addition, the programming details (specific contacts, stimulation amplitude, pulse width and frequency) before and after VAS-programming are specified. The type of stimulation is specified indicating either ring mode (r) or the use of subsegments on a given ring level (s). The ring level indicates the electrode height on a four-level lead (i.e., 1, 2, 3, or 4).
