Summary of demographic information for Control, PDAR, and PDT subjects included in the study. Age, disease duration, total UPDRS, Hoehn & Yahr score, LED, and Tremor/AR ratio were compared using a two-tailed t-test. PDAR – akinetic/rigid predomiant PD, PDT – tremor predominant PD, NA – not applicable, mon – months, tremor/AR ratio – tremor/akinetic-rigidity ratio.

Comparison of age for Controls and PDAR subjects p=0.990, Controls and PDT subjects p=0.139, and for PDAR and PDT subjects p=0.066.
**
P value reflects the comparison between PDAR and PDT subjects.
