Objective: To investigate the effects of low frequency electrical stimulation on monoamine neurotransmitters, cerebral blood flow and hemorheology in children with cerebral palsy. Methods: A total of 83 children with cerebral palsy were divided into the control group (n=42) and the observation group (n=41) according to the random data table, patients in the control group were treated with routine rehabilitation treatment, on this basis; the children in the observation group were treated with low-frequency electric stimulation. Before and after the treatment, the levels of monoamine neurotransmitter [dopamine (DA) and 5-hydroxy tryptamine (5-HT) and norepinephrine (NE)], cerebral blood flow [the average blood flow velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA)] and blood rheology index [high/low shear whole blood viscosity, plasma viscosity and fibrinogen (FIB)] of two groups were compared. Results: Before treatment, there were no significant difference of the levels of DA, 5-HT, NE, the average blood flow velocity of ACA/MCA/PCA, high/low shear whole blood viscosity, plasma viscosity and FIB between the two groups. After treatment, two groups of DA, 5-HT and NE levels were significantly higher than those in the same group before treatment, and the observation group of DA, 5-HT and NE levels were significantly higher than those of the control group, the difference was statistically significant; The average blood flow rate of ACA/MCA/PCA in the observation group after treatment was significantly higher than those in the same group before treatment; After treatment, the levels of high shear/low shear blood viscosity, plasma viscosity and FIB of the two groups were significantly lower than those in the same group before treatment, and the levels of observation group after treatment were significantly lower than that in the control group, the difference was statistically significant. Conclusion: Low frequency electrical stimulation can effectively increase the level of monoamine neurotransmitter, improve the level of cerebral blood flow and hemorheology, has an important clinical value.
