Objective:To observe the clinical effect of different frequencies of transcutaneous electrical acupoint stimulation in treating postpartum pelvic girdle pain and promoting postpartum rehabilitation.Methods:From January to September 2022,300 patients with pelvic girdle pain after spontaneous delivery in a hospital in Shaanxi Province were selected and randomly divided into three groups,low frequency,high frequency,and alternating frequency,with 100 cases in each group.In addition to routine postpartum care and psychological counseling,the three groups received transcutaneous electrical acupoint stimulation at low-frequency(2 Hz,)high-frequency(100 Hz),and alternating frequency(2/100 Hz),respectively.The differences in initial pain,pain scores before and after treatment,satisfaction with analgesic effect,and postpartum rehabilitation effect were evaluated among the three groups of patients.Results:There was a significant correlation between maternal age and postpartum pelvic girdle pain(P<0.001),but no correlation was observed between newborn birth weight and postpartum pelvic girdle pain(P>0.05).After 1d/2d of treatment,the pain scores and rehabilitation effect of patients in the alternating-frequency group and low-frequency group were significantly better than those in the high-frequency group,and the postpartum curative effect of patients in the alternating-frequency group was the best,followed by the low-frequency group,and the high-frequency group;the differences were statistically significant(P<0.001).Among the three groups,the alternating-frequency group had the highest satisfaction with the analgesic effect and the highest rate of selecting the same analgesic regimen the next time;the differences were statistically significant(P<0.001).Conclusion:Transcutaneous electrical acupoint stimulation at different frequencies is safe and effective in treating postpartum pelvic girdle pain and beneficial to postpartum rehabilitation.Sparse-dense wave stimulation is effective in treating postpartum pelvic girdle pain.It has the best effect in promoting postpartum rehabilitation and the highest patient satisfaction.Therefore,its application in clinical practice is highly recommended.

Changes in plasma calcitonin gene-related peptide and serum neuron specific enolase in rats with acute cerebral ischemia after low-frequency electrical stimulation with different waveforms and intensities

Following acute cerebral ischemia in rats, plasma calcitonin gene-related peptide decreased and the level of serum neuron specific enolase and the volume of the infarction increased. Square-wave and triangular-wave electrical stimulation with low or high intensities could increase the plasma calcitonin gene-related peptide, decrease the serum neuron specific enolase and reduce the infarction volume in the brain in rats with cerebral ischemia. There was no significant difference between different wave forms and intensities. The experimental findings indicate that low-frequency electrical stimulation with varying waveforms and intensities can treat acute cerebral ischemia in rats.

Effects of routine rehabilitation therapy combined with low frequency electrical stimulation on monoamine neurotransmitters, NSE, ET-1 and cerebral hemodynamics in children with cerebral palsy

Objective:To investigate the effects of routine rehabilitation therapy combined with low frequency head stimulation on monoamine neurotransmitters, neuron-specific enolase (NSE), endothelin-1 (ET-1) and cerebral hemodynamics in children with cerebral palsy.Methods:From January 2017 to June 2018, 110 children with cerebral palsy were randomly divided into observation group (55 cases) and control group (55 cases). The control group received routine rehabilitation treatment, while the observation group received low-frequency head stimulation on the basis of routine rehabilitation treatment. The changes of dopamine (DA), norepinephrine (NE), serotonin (5-HT), NSE, ET-1 levels and mean blood flow velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA) were compared in two groups.Results:Before treatment, there was no significant difference in DA, NE and 5-HT levels in two groups. After treatment, DA, NE and 5-HT levels in the observation group were (192.23±22.71) ng/mL, (98.02±11.71) ng/L, (210.07±25.03) ng/L, and in the control group. the DA, NE, 5-HT levels were (147.06±17.02) ng/mL, (83.07±11.15) ng/L, and (171.88±20.45) ng/L, respectively. The DA, NE and 5-HT levels in two groups were higher than those before treatment, and DA, NE and 5-HT levels in the observation group were higher than those in the control group. Before treatment, there was no significant difference in NSE and ET-1 levels between the two groups. After treatment, the NSE and ET-1 levels in the observation group were (7.97±2.07) μg/L and (41.01±10.07) pg/mL, and the NSE and ET-1 levels in the control group were (10.38±3.02) μg/L, (58.46±15.02) pg/mL, respectively. the NSE and ET-1 in two groups were lower than those before treatment, and the NSE and ET-1 of the observation group were lower than the control group. Before treatment, there was no significant difference in mean blood flow velocity between ACA, MCA and PCA. After treatment, the mean blood flow velocities of ACA, MCA, and PCA in the observation group were (46.88±7.72) cm/s, (59.85±10.18) cm/s, and (49.15±7.02) cm/s, respectively, which was significantly higher than before treatment and higher than that of the control group in the same period.Conclusion: Conventional rehabilitation combined with low-frequency electrical stimulation of the head can effectively increase the content of monoamine neurotransmitters in children with cerebral palsy, enhance cerebral blood circulation, and reduce brain damage.

Effects of cervical low-frequency electrical stimulation with various waveforms and densities on body mass,liver and kidney function,and death rate in ischemic stroke rats

Low-frequency electrical stimulation has resulted in favorable effects in the treatment of post-stroke dysphagia. However, the safety of cervical low-frequency electrical stimulation remains unclear because of numerous nerves and blood vessels in the neck. In the present study, rats with ischemic stroke underwent low-frequency electrical stimulation, and systemic and local effects of electrical stimulation at different densities and waveforms were investigated. Electrical stimulation resulted in no significant effects on body mass, liver or kidney function, or mortality rate. In addition, no significant adverse reaction was observed, despite overly high intensity of low-frequency electrical stimulation, which induced laryngismus, results from the present study suggested that it is safe to stimulate the neck with a low-frequency electricity under certain intensities.

Effects of low frequency electrical stimulation on monoamine neurotransmitters,cerebral blood flow and hemorheology in children with cerebral palsy

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.

Effect of Unilateral Low-Frequency Stimulation of Hippocampus on Rapid Kindling—Induced Seizure Development in Rats

Since the last decade deep brain stimulation has been proposed as an alternative treatment for patients who do not become seizure-free with the current pharmacological treatments and cannot undergo resective surgical procedure. However, the optimal stimulation parameters remain undetermined and active research in humans and animals is necessary. The present study was designed to investigate the effect of unilateral Low Frequency Stimulation (LFS) of hippocampus on seizure development by using the hippocampal rapid kindling method (hRK) in rats. We used male Wistar rats implanted with electrodes in the ventral hippocampus. All rats underwent hRK (biphasic square wave pulses, 20 Hz for 10 seconds) during three consecutive days (twelve stimulations per day). The control group (hRK;n = 6) received only RK stimulus, while the treated group (LFS-hRK;n = 8) received also LFS (biphasic square wave pulses, 1 Hz for 30 seconds) immediately before the RK stimulus, during three consecutive days. At the end of behavioral testing on day 3, 62% (P < 0.05) of the animals receiving LFS treatment were still not fully kindled staying in stages 0-III (P < 0.01). The number of stimulations needed to achieve generalized seizures (stage IV-V of Racine scale) was significantly higher (P < 0.05) in the LFS group with respect to control group. No significant differences in the cumulative daily afterdischarge duration were observed between both groups. These findings suggest that preemptive LFS can significantly decrease the incidence of hippocampus-kindled seizures and delay the progression and secondary generalization of focal seizures.

Treatment time influences the effects of a low-frequency pulsed electric field on synthesis of tyrosine hydroxylase and dopamine in PC12 cells

BACKGROUND： Electromagnetic radiation can influence dopamine （DA） synthesis in brain tissues or ceils, but electromagnetic frequencies, intensities, and radiation time can produce different effects. In addition, the signal pathway by which electromagnetic radiation influences DA synthesis remains controversial. OBJECTIVE： To determine tyrosine hydroxylase （TH） expression in PC12 cells and DA levels in cell culture media after different periods of low-frequency pulsed electric field （LF-PEF） stimulation, and to determine how LF-PEF signaling stimulates TH synthesis using inhibitors. DESIGN, TIME AND SETTING： A parallel, controlled, cell experiment was performed at the Laboratory of Cell Biology, School of Life Science, East China Normal University, between January and October 2006. MATERIALS： PC12 cells were purchased from the Shanghai Institute of Biochemistry and Cell Biology, Chinese Academy of Sciences, China. Nerve growth factor was purchased from PeproTech, USA. The protein kinase A inhibitor, H-89, and mitogen-activated protein kinase kinase inhibitor, U0126, were purchased from Sigma, USA. METHODS： （1） Following routine culture in Dulbecco＇s modified eagle medium, primary PC12 cells were stimulated under LF-PEF （pulse frequency 50.Hz, pulse width 20 μs, peak field strength 1 V/m） for 5, 10, 15, 20, and 30 minutes. （2） Inhibitors （H-89 or U0126, 1 μmol/L） were added 30 minutes before LF-PEF stimulation for 10 minutes. MAIN OUTCOME MEASURES： （1） TH expression was determined by Western blot in PC12 cells at 0.5, 1,2, 3, and 4 days after LF-PEF stimulation. Similarly, DA was measured by high-performance liquid chromatography in media at 2, 3, 4, or 5 days after LF-PEE （2） TH expression was detected 1 day after H-89 or U0126 treatment and LF-PEE RESULTS： （1） Short-term LF-PEF stimulation （5 and 10 minutes） increased TH expression and media DA levels after short-term culture （2 days） （P 〈 0.01）, but both parameters decreased with longer culture （3 4 days） （P 〈 0.01）. Long-term LF-PEF stimulation （15, 20, or 30 minutes） decreased TH and DA synthesis, followed by a rapid increase （P 〈 0.01）. （2） H89 could completely inhibit TH expression in PC12 cells stimulated by LF-PEF for 10 minutes, while the inhibition rate of U0126 was 53.2%. CONCLUSION： Short-term LF-PEF first promotes then inhibits, while long-term LF-PEF first inhibits then promotes, TH and DA synthesis. LF-PEF stimulation regulates TH expression primarily by activating protein kinase A to regulate DA synthesis.

Electrical stimulation upregulates angiopoietin-1/Tie-2 mRNA expression in a rat model of focal cerebral ischemia

Angiopoietin-1/tyrosine kinase with immunoglobulin and epidermal growth factor homology domains 2 （Tie-2） is a newly discovered signaling pathway of angiogenesis. Angiogenesis benefits recovery of neurological functions such as swallowing. In the present study, a rat model of dysphagia following stroke was induced by middle cerebral artery occlusion to investigate the influence of low frequency electrical stimulus with bidirectional square waves and triangular waves on angiopoietin-1/-13e-2 mRNA expression. Reverse transcription-polymerase chain reaction results showed that low frequency electrical stimulus significantly improved the neurological scores of the model rats, and increased angiopoietin-1/＇13e-2 mRNA expression. This demonstrates that low frequency electrical stimulation can ameliorate neurological function in rats with focal brain ischemia, potentially through regulation of angiopoietin-1/-13e-2 expression in the angiogenesis pathway.

Hippocampal High-Frequency Stimulation Inhibites the Progression of Rapid Kindling-Induced Seizure in Rats

Epilepsy is one of the most common serious neurological disorders. Pharmacoresistant epilepsy patients are poorly controlled or their seizures are refractory to drug treatment. Resective surgery is frequently a promising therapy in this population, however, not all the patients meet the eligibility criteria for the surgical treatment. Deep brain stimulation has been investigated in clinical studies and animal studies as an alternative treatment, but the optimal stimulation parameters remain an issue. The present study was designed to investigate the effect of unilateral high-frequency stimulation (HFS) of hippocampus on seizure development by using the hippocampal rapid kindling method (hRK) in rats, and compared the results with those of low-frequency stimulation previously published by our group. We used male Wistar rats implanted with electrodes in the ventral hippocampus. All rats underwent hRK (biphasic square wave pulses, 20 Hz for 10 seconds) during three consecutive days (twelve stimulations per day). The control group (hRK;n = 7) received only RK stimulus, while the treated group (HFS-hRK;n = 9) received also HFS (biphasic square wave pulses, 130 Hz for 30 seconds) immediately before the RK stimulus, during three consecutive days. At the end of behavioral testing 78% (p 0.01) of the animals receiving HFS treatment were still not fully kindled staying in stages 0 -III (p 0.01). HFS group needed a higher number of stimulations to achieve stage III (p 0.05) with respect to control group. However, no significant differences in the cumulative daily afterdischarge duration were observed. HFS did not present significant differences compared with LFS in any of studied parameters. The findings suggest that unilateral HFS applied on hippocampus effectively inhibited the epileptogenic process induced by hippocampal rapid kindling. According to the comparative results about hippocampal rapid kindled animals stimulated with HFS and LFS (5 Hz), we found no conclusive information on which treatment is most efficient.

不同频率电刺激促进周围神经损伤的恢复

背景:电刺激是治疗周围神经损伤有效的治疗方案,但不同频率电刺激促进周围神经恢复的机制和应用不同。目的:旨在系统梳理和总结不同频率电刺激在周围神经损伤治疗中的作用和应用,深入分析各种方法的优缺点,以期找到最有利于患者神经恢复的治疗策略。方法:应用计算机检索中国知网、PubMed数据库自建库至2024年5月期间的相关文献,英文检索词为“peripheral nerve injury,electrical stimulation,low frequency electrical stimulation,medium frequency electrical stimulation,high frequency electrical stimulation,TENS,interfering electricity,short wave,ultrashort wave,frequency”,中文检索词为“周围神经损伤,电刺激,低频电刺激,中频电刺激,高频电刺激,干扰电疗法,短波,超短波,频率,周围神经再生”,最终纳入74篇文献进行分析。结果与结论:周围神经损伤作为临床中常见的疾病,会引起患者感觉与运动功能障碍。低频电刺激能够促进电刺激后细胞增殖并加速细胞内神经生长因子表达,促进巨噬细胞募集和浸润,加速髓磷脂碎片的清除,促进受损轴突的髓鞘再生。中频电刺激能够作用于更深部位组织,对于缓解神经性疼痛方面更佳。高频电刺激能够促进施万细胞和巨噬细胞增殖并抑制炎性因子,更快募集到神经损伤部位,加快神经修复的速度。不同频率的电刺激在周围神经损伤恢复中各具优点,但是仍存在一些问题,例如电刺激的部位以及应对各种疾病类型的方案不同等。
