  • Motor UPDRS, Total score of the motor examination section of the UPDRS (items 18–31); DUEBR, dominant upper extremity bradykinesia and rigidity (total of UPDRS items 22–25 for the arm tested); RH, right hand; LH, left hand; M, male; F, female; Ctl, control. The numbers in parentheses indicate the range of possible scores for each measure. p value data: two-sample t test for age; Fisher's exact test for handedness and sex.
