Characteristic of subjects.

Group	Case	Gender	Age	Disease duration (mo)	Scores for ordinary BIT	Scores for action BIT	Lesion
USN(+)	A	Male	65	4	128	68	Parietal lobe
	B	Male	81	31	66	49	Parietolateral lobe
	C	Male	65	5	22	11	Putamen
	D	Male	68	51	105	47	Putamen
	E	Female	72	6	127	53	Putamen
	F	Male	63	5	40	24	Putamen
USN(−)	G	Female	68	32	138	76	Putamen
	H	Female	41	6	144	77	Putamen
	I	Female	63	8	135	73	Putamen
	J	Male	55	36	144	77	Putamen
	K	Male	75	26	143	77	Putamen
	L	Male	55	5	145	81	Occipitotemporal lobe

An ordinary BIT score of 131 or greater together with an action BIT score of 68 or greater determined the presence of USN. There was no significant difference in age (𝑃=0.11) or disease duration (𝑃=0.41) between the USN-positive and -negative groups.
