**P < 0.01, initial VMR values versus VMR values after EA stimulation in EA group. F(6, 35) = 7.613, P = 0.000 for days 19 and 22 with 40 mmHg; F(6, 35) = 6.738 for 22, P = 0.000 for days 19 and 22 with 60 mmHg; F(6, 35) = 12.690, P = 0.000 for days 16, 19 and 22 with 80 mmHg; F(6, 35) = 17.432, P = 0.000 for days 16, 19 and 22 with 100 mmHg. One-way ANOVA is followed by Bonferroni post-hoc test.
