  1. Clinical scores are given as total score of the Movement Disorder Society Unified Parkinson’s disease rating scale (UPDRS) part III for levodopa off/on (pre-surgery) and as items 3–8 & 14–18 (limb scores) for DBS off/on. Medication is given in levodopa-equivalent daily dose (LEDD). Standard deviation and range are presented within the brackets.
  2. aSex was assigned.
  3. bStimulation intensity for electrodes of the contralateral and ipsilateral STN (in relation to the drawing hand) in mA.
  4. cItems 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.14, 3.15, 3.16, 3.17, and 3.18.
  5. dP < 0.001 (two-sided paired samples t-test).
