UPDRS-III score and limb rest tremor and rigidity during the measurement phases I–IV.

	UPDRS-III	Tremor	Rigidity
Range	0–108	0–16	0–16
I	37.2 ± 7.9	1.9 ± 2.4	6.9 ± 3.2
II	–	0.4 ± 0.5	3.0 ± 3.2
III	12.7 ± 5.0	0.0 ± 0.0	2.0 ± 2.5
IV	–	0.5 ± 1.2	3.5 ± 2.4

The whole UPDRS-III was done in phases I and III, the limb rigidity and rest tremor assessment were done in each phase I–IV. The maximum of each item in UPDRS-III is 4, though the whole range of limb tremor and rigidity is 0–16.
