Research on the Different Frequencies of Transcutaneous Electrical Acupoint Stimulation for Postpartum Pelvic Girdle Pain

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.

Transcutaneous electrical acupoint stimulation in adult patients receiving gastrectomy/colorectal resection:A randomized controlled trial

BACKGROUND Acupuncture promotes the recovery of gastrointestinal function and provides analgesia after major abdominal surgery.The effects of transcutaneous electrical acupoint stimulation(TEAS)remain unclear.AIM To explore the potential effects of TEAS on the recovery of gastrointestinal function after gastrectomy and colorectal resection.METHODS Patients scheduled for gastrectomy or colorectal resection were randomized at a 2:3:3:2 ratio to receive:(1)TEAS at maximum tolerable current for 30 min immediately prior to anesthesia induction and for the entire duration of surgery,plus two 30-min daily sessions for 3 consecutive days after surgery(perioperative TEAS group);(2)Preoperative and intraoperative TEAS only;(3)Preoperative and postoperative TEAS only;or(4)Sham stimulation.The primary outcome was the time from the end of surgery to the first bowel sound.RESULTS In total,441 patients were randomized;405 patients(58.4±10.2 years of age;247 males)received the planned surgery.The time to the first bowel sounds did not differ among the four groups(P=0.90;log-rank test).On postoperative day 1,the rest pain scores differed significantly among the four groups(P=0.04;Kruskal–Wallis test).Post hoc comparison using the Bonferroni test showed lower pain scores in the perioperative TEAS group(1.4±1.2)than in the sham sti-mulation group(1.7±1.1;P=0.04).Surgical complications did not differ among the four groups.CONCLUSION TEAS provided analgesic effects in adult patients undergoing major abdominal surgery,and it can be added to clinical practice as a means of accelerating postoperative rehabilitation of these patients.

Effect of transcutaneous electrical acupoint stimulation combined with palonosetron on chemotherapy-induced nausea and vomiting: a single.blind,randomized, controlled trial

Background: Chemotherapy?induced nausea and vomiting adversely affects the quality of life of patients who receive chemotherapy via intravenous infusion or transcatheter arterial chemoembolization(TACE). This study aimed to investigate the clinical effects of transcutaneous electrical acupoint stimulation(TEAS) on nausea and vomiting after TACE.Methods: A total of 142 patients who received TACE with cisplatin for primary or metastatic liver cancer were assigned to the active?acupuncture(n = 72) or placebo?acupuncture(n Hegu(LI4), Neiguan(P6), an= 70) groups using a covariate?adaptive randomization at a ratio of 1:1. The acupointsd Zusanli(ST36) were stimulated twice daily for 6 days. The effects of TEAS on nausea and vomiting were assessed by using occurrence rate and severity of these symptoms. Anorexia scale and M. D. Anderson Symptom Inventory(MDASI) scores were secondary endpoints and were used to assess the effect of TEAS on patient appetite and quality of life. The safety of the treatments was also monitored.Results: Between the two groups, the differences in occurrence rates and severities of nausea and vomiting after TACE were not significant(all P > 0.05). From the second day after TACE, anorexia scores were significantly lower in the active?acupuncture group than in the placebo?acupuncture group and continued to decrease over time with treat?ment(all P values less than 0.01). On days 0, 1, and 2, the mean MDASI scores for the active?acupuncture group were slightly lower than those for the placebo?acupuncture group, but the differences were not statistically significant(all P > 0.05). No significant differences were found between the two groups in the occurrence rate of any adverse event(P > 0.05).Conclusion: TEAS appears to be a safe and effective therapy to relieve patients' gastrointestinal discomfort after chemotherapy.

Evaluation of the Efficacy of Transcutaneous Electrical Acupoint Stimulation during the Treatment of Painless Colonoscopy

Objective:To investigate the clinical efficacy of transcutaneous electrical acupoint stimulation combined with propofol infusion during the treatment of patients under colonoscopy.Methods:A total of 90 patients received painless colonoscopy were randomly divided into three groups:transcutaneous electrical acupoint stimulation combined with propofol group(group T),sufentanil combined with propofol group(group S)and propofol group(group P),with 30 cases in each group.The patients in group T were anesthetized with propofol after transcutaneous electrical acupoint stimulation of 30min at Hegu(LI4),Neiguan(PC6),Zusanli(ST36),Shangjuxu(ST37)and Sanyinjiao(SP6)on both sides,and the electrical stimulation lasted until the end of the operation.Group S and group P were pasted electrode slices at the same acupoint with group T,but no electrical stimulation was given.The other treatments were the same as those in group T.Group S was given sufentanil 0.1ug/kg at the beginning of anesthesia.The levels of blood pressure(MAP),heart rate(HR)and pulse oxygen saturation(SpO2)were continuously monitored at time points of entering operating room(T0),disappearance of eyelash reflex(T1),during operation(through the liver region T2)and immediately after operation(T3),and the total dosage of propofol,awakening time and incidence of adverse reactions in each group were recorded.Results:Compared with group P,the blood pressure and heart rate of the patients at T1 and T2 in group T were more stable(P<0.05),the awakening time after operation was significantly shorter(P<0.05),and the dosage of propofol was significantly lower than that in group P(P<0.05).The incidence of bradycardia,hypotension and respiratory depression decreased significantly(P<0.05).Compared with group S,the postoperative awakening time of group T was significantly shorter(P<0.05),and there was no significant difference in other indexes.Conclusion:Transcutaneous electrical acupoint stimulation is effective during the treatment of analgesia under colonoscopy.It can reduce the dosage of anesthetics,reduce the incidence of postoperative adverse reactions and shorten the awakening time of patients.

Objective：To investigate the efficacy of transcutaneous electrical nerve stimulation（TENS）on four specific acupuncture points Hegu（LI4）,Neiguan（PC6）,Danshu（BL19）and Weishu（BL21）for reducing pain in labor.Methods：A total of 160 voluntary nulliparous women who were willing to receive TENS for analgesia were assigned to the treatment group after cervical dilation of more than 2 cm.Another 145 matched nullipara were recruited as the control group.Visual analogue scale（VAS）was used to assess the pain before and 0.5 h after the application of TENS.Then,VAS was assessed every one hour until delivery.Percentage of VAS score decreased by〉25%was the primary outcome,the delivery mode and neonatal outcome were measured as secondary outcomes.Adverse reactions were also recorded during TENS.Results：The percentage of VAS score decreased by〉25%was 68.6%in the TENS treatment group.Maternal delivery mode and neonatal outcomes were not significantly different between the two groups.In addition,the incidence of postpartum hemorrhage in the TENS treatment group was less than the control group（P〈0.05）.There was no adverse reaction recorded with TENS on acupoints.Conclusion：As a novel and non-invasive approach,TENS on specific acupoints including Hegu（LI4）,Neiguan（PC6）,Danshu（BL19）and Weishu（BL21）was an effective method for analgesia in labor.

Perioperative transcutaneous electrical acupoint stimulation for improving postoperative gastrointestinal function:A randomized controlled trial

Background:Postoperative gastrointestinal dysfunction(PGD)is one of the most common complications in patients undergoing major abdominal surgery.Acupuncture has been used widely in gastrointestinal diseases due to its effectiveness and minimally invasive nature.Objective:This study evaluated the efficacy of using transcutaneous electrical acupoint stimulation(TEAS)during the surgery and postoperative recovery in patients with gastric and colorectal surgery for improving postoperative gastrointestinal function.Design,setting,participants and interventions:A total of 280 patients undergoing abdominal surgery were stratified by type of surgery(i.e.,gastric or colorectal surgery)and randomly allocated into the TEAS group(group T)or the sham group(group S).Patients in group T received TEAS at LI4,PC6,ST36 and ST37.Patients in group S received pseudo-TEAS at sham acupoints.The stimulation was given from 30 min before anesthesia until the end of surgery.The same treatment was performed at 9 am on the 1st,2nd and 3rd days after surgery,until the recovery of flatus in patients.Main outcome measures:The primary outcome was the time to the first bowel motion,as detected by auscultation.The secondary outcomes included the first flatus and ambulation time,changes of perioperative substance P(SP),incidence of PGD,postoperative pain,postoperative nausea and vomiting(PONV)and some economic indicators.Results:The time to first bowel motion,first flatus and first ambulation in group T was much shorter than that in group S(P<0.01).In patients undergoing colorectal surgery,the concentration of SP was lower in group T than in group S on the third day after the operation(P<0.05).The average incidence of PGD in all patients was 25%,and the frequency of PGD was significantly lower in group T than in group S(18.6%vs.31.4%,respectively;P<0.05).TEAS treatment(odds ratio=0.498;95%confidence interval:0.232–0.786)and type of surgery were relevant factors for the development of PGD.Postoperative pain score and PONV occurrence were significantly lower in group T(P<0.01).Postoperative hospitalization days and the resulting cost to patients were greatly reduced in the TEAS group(P<0.01).Conclusion:Perioperative TEAS was able to promote the recovery of postoperative gastrointestinal function,reduce the incidence of PGD and PONV.The concentration of SP was decreased by TEAS treatment,which indicates that the brain-gut axis may play a role in how TEAS regulates gastrointestinal function.Trial registration:Chinese Clinical Trial Registry,Chi CTR1900023263.

Effects of Transcutaneous Electrical Acupoint Stimulation on Ovarian Responses and Pregnancy Outcomes in Patients Undergoing IVF-ET:A Randomized Controlled Trial

Objective:To evaluate the influence of different transcutaneous electrical acupoint stimulation(TEAS)modes on ovarian responses and pregnancy outcomes in patients with infertility undergoing in vitro fertilization and embryo transfer(IVF-ET).Methods:Two hundred infertility patients undergoing IVF-ET were divided randomly into experimental groups(TEAS groups:E-Ⅰ,E-Ⅱ,E-Ⅲ,and E-Ⅳ,40 cases each group)and a control group(mock TEAS group,40 patients)using the random number method.The patients in the experimental groups received TEAS treatment of 20,30,40 and 50 m A for the E-Ⅰ,E-Ⅱ,E-Ⅲand E-Ⅳgroups,respectively.The control group received a treatment of 5 m A.TEAS was applied at acupoints of Guanyuan(RN 4),Zhongji(RN 3),Sanyinjiao(SP 6),Zigong(EX-CA 1),and Taixi(KI 13),once a day for 30 min each time for a treatment period of 10-13 d.Treatment effect was assessed using the following indicators:endometrial thickness on the 6 th day of gonadotropin treatment(GN6 day),endometrial thickness on the day on chorionic gonadotropin administration(HCG day),number of ovarian follicles on HCG day,number of ova captured,amount of estrogen required for each harvested ova,number of mature ova divided by the total number of ova,percentage of high-quality embryos,and clinical pregnancy.Results:Endometrial thickness in the experimental groups on the HCG day was significantly better than that of the control group after TEAS stimulation(P=0.01).TEAS exhibited a greater impact on the number of ova captured(P=0.003).However,the effect of TEAS stimulation on the high-quality embryo rate and clinical pregnancy in patients was not statistically significant(P>0.05).Conclusions:TEAS is an effective method in improving the ovarian state.When the stimulus intensity was at 40 m A and above,it could be helpful to improve the patient’s endometrial condition and endometrial receptivity and to retrieve more oocytes.(Trial registration No.Chi CTR-TRC-11001780)

目的:探讨经皮穴位电刺激(Transcutaneous Electrical Acupoint Stimulation,TEAS)复合药物全麻行控制性降压对肝脏的影响,并为临床行针药复合麻醉提供实验依据。方法:18只雄性比格犬随机分为单纯药物全麻组(单纯全麻组)(6只)、单纯药物全麻行控制性降压组(对照组)(6只)和经皮穴位电刺激复合药物全麻行控制性降压组(实验组)(6只)。后两组动物均以异氟醚联合硝普钠行控制性降压,将动脉血压降至60%基础平均动脉血压(Mean arterial pressure,MAP)水平并维持60min,单纯全麻组不行控制性降压。实验组采用TEAS干预处理,刺激强度(4±1)mA,频率2/100Hz,穴位选用犬双侧"合谷(LI 4)"、"曲池(LI 11)"、"足三里(ST 36)"、"三阴交(SP 6)",电刺激在动物生理状态稳定后开始至维持目标MAP60min后停止。采用激光多普勒组织血流仪监测相应时间点肝组织表面血流的变化,用免疫组化法检测术后肝组织中GSH活性、T-SOD活力以及MDA含量的变化,并采用TUNEL法检测术后72h肝组织细胞凋亡数。结果:在行控制性降压至目标低血压(T3)时,对照组肝血流显著低于基础水平(P<0.05),而实验组肝血流未明显降低,在目标低血压维持10min(T4)时,两控压组肝血流显著低于各自基础水平(P<0.05),在维持20min至维持60min阶段(T5～T7),两控压组肝血流显著低于单纯全麻组水平和各自基础水平(P<0.05),且对照组肝血流维持水平更低,在血压回升阶段,实验组肝血流上升明显,在血压回升10min(T8)时,实验组肝血流已基本恢复,而对照组肝血流仍低于同期单纯全麻组水平,在血压回升60min和回升结束(T11～T12),实验组肝血流明显高于对照组水平(P<0.05)。与单纯全麻组相比,控制性降压术后两控压组GSH活性均有显著升高(P<0.05),且实验组较对照组相比升高趋势更明显。实验组SOD/MDA比值显著升高(P<0.05),而对照组升高不明显。实验组肝组织细胞凋亡数(3.2±1.09)明显低于同水平对照组(5.47±1.02)(P<0.05),但与空白组(3.49±1.42)相比,无统计学差异(P>0.05)。结论:TEAS复合药物全麻行控制性降压能有效改善肝组织血流的低灌注状态,增强肝脏的抗自由基能力,抑制肝细胞凋亡,起到肝保护作用。

TEAS对IVF肾气虚型患者子宫内膜容受性影响

目的:观察经皮穴位电刺激(TEAS)治疗对IVF肾气虚型患者冻胚移植周期子宫内膜容受性的影响。方法:将我院收集的153例符合纳入标准的行冻胚移植的肾气虚型患者随机分为TEAS治疗组、MOCK组、对照组。观察3组患者治疗前后临床指标的变化,以及妊娠结局的差异。结果:3组患者的平均年龄、不育年限、体重指数、基础FSH比较差异无统计学意义。治疗后,TEAS组患者中医证候评分较治疗前明显降低,差异有统计学意义(P<0.05)。黄体酮注射日TEAS组的子宫内膜厚度高于MOCK组和对照组,差异有统计学意义(P<0.05);TEAS组A型与AB型子宫内膜百分比、(+、++)型子宫内膜下血流明显高于MOCK组和对照组,差异有统计学意义(P<0.05);黄体酮注射日3组血清E2、P比较,差异无统计学意义(P>0.05);TEAS组PI、RI、S/D低于治疗前,与MOCK组、对照组比较明显降低,差异均有统计学意义(P<0.05),治疗前后MOCK组与对照组两组间、组内比较差异均无统计学差异(P>0.05)。TEAS组HCG阳性率及临床妊娠率明显高于MOCK组与对照组,差异有统计学意义(P<0.05)。MOCK组与对照组比较无统计学差异(P>0.05)。结论:TEAS治疗能改善IVF肾气虚型患者的中医临床症状及体征,增加子宫内膜厚度,降低子宫内膜血流参数PI、RI、S/D,进而提高患者的子宫内膜容受性,改善临床妊娠结局。

中医证候量表评价TEAS治疗腹泻型肠易激综合征的相关性研究

目的:应用中医证候量表评价经皮穴位电刺激法(TEAS)治疗腹泻型肠易激综合征(IBS-D)的相关性。方法:110例IBS-D患者随机分为两组,治疗组予TEAS刺激太冲、阴陵泉和天枢三穴,每天2次;对照组予TEAS模拟治疗,疗程4周。评价中医证候量表积分与肠道症状积分、生活质量积分的相关性,并评估治疗前后受试者的中医证候改善情况。结果:肠道症状总积分以及腹痛程度、腹痛天数、腹胀情况、排便满意度、生活干扰度、排便次数、急迫天数等与中医证候呈正相关(P<0.05,P<0.01);生活质量总积分以及睡眠质量、精力改变、工作影响等与中医证候积分呈负相关(P<0.05,P<0.01)。治疗结束后,TEAS治疗组对主症大便泄泻、腹痛、胸胁胀闷,次症脘腹胀满、抑郁烦躁、肠鸣矢气、嗳气、太息,以及中医证候总积分的改善优于TEAS模拟组(P<0.05,P<0.01)。结论:中医证候与IBS-D患者的肠道症状、生活质量相关,采用中医证候量表能反映IBS-D肝气乘脾证的证候改善情况,TEAS能有效改善IBS-D肝气乘脾证患者的中医证候。
