Table 2.

Ratio calculation for PD motor subtypes.

Scale UPDRS MDS-UPDRS
Formula TD/AR ratio = TD score/ AR score
AR score = sum of rigidity items/12
TD score = sum of tremor items/9
TD/AR ratio = TD score/ AR score
AR score = sum of rigidity items/15
TD score = sum of tremor items/11
Cutoff score Tremor Dominant ≥ 0.97
Akinetic Rigid ≤ 0.80
Mixed > 0.80 and < 0.97
Tremor Dominant ≥ 0.82
Akinetic Rigid ≤ 0.71
Mixed > 0.71 and < 0.82
