  1. SAFFE: modified Survey of Activities and Fear of Falling in the Elderly.
  2. aFor each of the 17 activities, three response options are used: never avoid (coded 1), sometimes avoid (coded 2), and always avoid (coded 3). Thus, the total score can range from 17 to 51 points.
  3. 1Three participants left the questionnaire blank at time 1.
  4. 2Three participants did not complete retest (time 2). At time 2, data from 5 patients were excluded due to late responses and DBS surgery (see Results). Two participants left the questionnaire blank.
  5. None reached the maximum score of 51 points. At time 1, 13 out of 71 (18.3%) reached the lowest
  6. possible score (17 points). At time 2, 12 out of 62 (19.4%) attained the lowest possible score.
