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

Table 3

Two-sample t test to compare the FC values between two groups pre- and postacupuncture.

Acupuncture condition	Group of participants	FC (X ± S)	T value	P value
Preacupuncture	Stroke patients	0.062 ± 0.096	–0.682	0.499
	Healthy controls	0.044 ± 0.070
Postacupuncture	Stroke patients	0.130 ± 0.106	–4.355	< 0.001
	Healthy controls	0.018 ± 0.057

No significant differences were found between the two groups in the preacupuncture resting state. After acupuncture, the stroke group exhibited prominently greater enhanced FC compared with the healthy controls.
