Acupuncture Enhances Communication between Cortices with Damaged White Matters in Poststroke Motor Impairment

Table 4

Paired t test to compare the FC values between pre- and postacupuncture in stroke patients and healthy controls.

Group of participants	Acupuncture condition	FC (X ± S)	T value	P value
Stroke patients	Preacupuncture	0.062 ± 0.096	–3.544	0.002
	Postacupuncture	0.130 ± 0.106
Healthy controls	Preacupuncture	0.044 ± 0.070	1.306	0.206
	Postacupuncture	0.018 ± 0.057

A significant connectivity increase (pre- and postacupuncture FC changes) was observed in the stroke group but not in the healthy controls.
