The effect of AF (at 0.0083 Hz) on logarithmic OCBF velocity (OCBFv) power at 0.03, 0.05, and 0.10 Hz. A: AF alone compared with baseline (solid bars) has no effect on logarithmic power at OLBNP frequencies. AF is followed by OLBNP (open bars) while flexion continues. B: the effect of OLBNP compared with baseline (open bars) on OCBFv power when it is applied first. The addition of AF follows (shaded bars). Comparing OCBFv power in A and B suggests that it is reduced by AF at each frequency of OLBNP. Values are means ± SE. *Significant difference of the comparison.
