Table 4.

Correlation between PLM MT(s) and UPDRS III for each diagnosis.

	OFF			ON			OFF-ON
	r	p-Value	n	r	p-Value	n	r	p-Value	n
PD	0.47	0.0013	44*	0.44	0.0019	47	0.47	0.0015	44*
MSA	0.49	0.0448	17	0.46	0.0635	17	0.05	0.8544	17
PSP	0.27	0.4860	9	0.22	0.5755	9	0.75	0.0210	9

*The PLM results for three PD patients in OFF were omitted from the correlation analysis due to freezing of gait phenomena yielding very long movement times.
