Methods: Thirty-two late-stage elderly individuals were evaluated for knee pain during rest, walking, and program exercises, with and without TENS. Gait analysis was performed using an IoT-based gait analysis device to examine the effects of TENS-induced analgesia on gait. Results: TENS significantly reduced knee pain during rest, walking, and programmed exercises, with the greatest analgesic effect observed during walking. The greater the knee pain without TENS, the more significant the analgesic effect of TENS. A comparison of gait parameters revealed a significant difference only in the gait cycle time, with a trend towards faster walking with TENS;however, the effect was limited. Conclusion: TENS effectively relieves knee pain in late-stage elderly individuals and can be safely applied during exercise. Pain management using TENS provides important insights into the implementation of exercise therapy in this age group.展开更多

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.展开更多

METHODS:Forty healthy subjects were randomized to receive 45 min of either Acu-TENS or placebo-TENS(no electrical output)over acupuncture points Hegu(largeintestine 4),Neiguan(pericardium 6)and Zusanli(stomach 36).A balloon catheter attached to a dual-drive barostat machine was then inserted into the subjects'rectum.A step-wise(4 mmHg)increase in balloon pressure was induced until maximal tolerable or 48 mmHg.Visual analogue scale and a 5-point subjective discomfort scale(no perception,first per-ception of distension,urge to defecate,discomfort/ pain and extreme pain)were used to assess rectal discomfort at each distension pressure.Blood beta-endorphin levels were measured before,immediately after intervention,at 24 mmHg and at maximal toler- able distension pressure. RESULTS:There was no difference in the demographic data and baseline plasma beta-endorphin levels between the two groups.Perception threshold levels were higher in the Acu-TENS group when compared to the placebo group,but the difference reached statistical significance only at the sensations"urge to defecate"and"pain".The distension pressures recorded at the"urge to defecate"sensation for the Acu-TENS and placebo-TENS groups were 28.0±4.5 mmHg and 24.6±5.7 mmHg,respectively(P=0.043);and the pressures recorded for the"pain"sensation for these two groups were 36.0±4.2 mmHg and 30.5± 4.3 mmHg respectively(P=0.002).Compared to the placebo group,a higher number of participants in the Acu-TENS group tolerated higher distension pressures (>40 mmHg)(65%in Acu-TENS vs 25%in placebo, P=0.02).The plasma beta-endorphin levels of the Acu-TENS group were significantly higher than that of the placebo group at barostat inflation pressure of 24 mmHg(1.31±0.40 ng/mL vs 1.04±0.43 ng/mL,P= 0.044)and at maximal inflation pressure(1.46±0.53 ng/mL vs 0.95±0.38 ng/mL,P=0.003). CONCLUSION:Acu-TENS reduced rectal discomfort during barostat-induced rectal distension and concur-rently associated with a rise in beta-endorphin level.展开更多

Methods: A total of 31 fatty liver volunteer patients were observed in this study. Changes of color Doppler energy (CDE) images before and after TEPS of local points nearby the liver were recorded by using color Doppler ultrasound diagnostic apparatus (ACUSON 128XP/10C). Sum of color pixel area (SCPA), average of color value (ACV) and SCPA×ACV (integral) of the hepatic flow images were analyzed by an image processing system, single blind method and paired t-test. Programmed TEPS (0.5- 150 Hz / 2 000 Hz , 10- 25 V ) was applied to the right Qimen (期门 LR 14)-Jingmen (京门 GB 25), Fuai (腹哀 SP 16)-Ganshu (肝俞 BL 18) respectively for 15 min. Results: Compared with basic values of pretreatment, SCPA, ACV and SCPA×ACV increased significantly (t=2.71, P<0.02; t=3.42, P<0.01; and t=8.15, P<0.001) after TEPS, meaning improvement of hepatic blood flow supply. Conclusion: TEPS of acupoints near the liver can improve hepatic blood flow and hepatic parenchymal microcirculation in patients with fatty liver.展开更多

Methods: Sixty ...Objective: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on nausea and vomiting (N&V) induced by patient controlled intravenous analgesia (PCIA) with Tramadol. Methods: Sixty patients who were ready to receive scheduled operation for tumor in the head-neck region and post-operation PCIA, aged 39-65 years, with the physique grades Ⅰ -Ⅱ of ASA, were randomized into two groups, A and B, 30 in each group. The pre-operation medication, induction of analgesia and continuous anesthesia used in the two groups were the same. TEAS on bilateral Hegu (LI4) and Neiguan (PC6) points was intermittently applied to the patients in group A starting from 30 min before analgesia induction to 24 h after operation, and the incidence and score of nausea and vomiting, antiemetic used, visual analogue scores (VAS), and PCIA pressing times in 4 time segments (0-4, 4-8, 8-12 and 12-24 h after the operation was finished) were determined. The same management was applied to patients in Group B, with sham TEAS for control. Results: The incidence and degree of N&V, as well as the number of patients who needed remedial antiemetic in Group A were less than those in Group B. The VAS score and PCIA pressing time were lower in Group A than those in Group B in the corresponding time segments respectively. Conclusion: TEAS could prevent N&V induced by PCIA with Tramadol.展开更多

文摘Purpose: This study verified the effects of transcutaneous electrical nerve stimulation (TENS), which can be worn during walking and exercise, in elderly individuals with late-stage knee pain who exercise regularly. Methods: Thirty-two late-stage elderly individuals were evaluated for knee pain during rest, walking, and program exercises, with and without TENS. Gait analysis was performed using an IoT-based gait analysis device to examine the effects of TENS-induced analgesia on gait. Results: TENS significantly reduced knee pain during rest, walking, and programmed exercises, with the greatest analgesic effect observed during walking. The greater the knee pain without TENS, the more significant the analgesic effect of TENS. A comparison of gait parameters revealed a significant difference only in the gait cycle time, with a trend towards faster walking with TENS;however, the effect was limited. Conclusion: TENS effectively relieves knee pain in late-stage elderly individuals and can be safely applied during exercise. Pain management using TENS provides important insights into the implementation of exercise therapy in this age group.

文摘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.

文摘Background:The present investigation tested the efficacy of the Tennant Biomodulator,a novel pain management intervention that uses biofeedback-modulated electrical stimulation,to reduce chronic pain and its psychosocial sequelae in a sample of current and former military service members.The Tennant Biomodulator used on its most basic setting was compared to two commonly used,non-pharmacological pain treatments—traditional Chinese acupuncture and transcutaneous electrical nerve stimulation(TENS)—in a comparative efficacy,randomized,open-label trial.Methods:Participants included 100 active duty and retired service men and women with chronic pain undergoing treatment at the Brooke Army Medical Center in Texas,USA,randomly assigned to receive six,weekly sessions of either Tennant Biomodulator treatment,traditional Chinese acupuncture,or TENS,in addition to usual care.Recruitment was conducted between May 2010 to September 2013.Outcome measures were collected at intake,before and after each treatment session,and at a 1-month follow-up.Intent-to-treat analyses were used throughout,with mixed models used to investigate main effects of group,time,and group×time interactions with consideration given to quadratic effects.Outcomes measured included ratings of chronic pain,pain-related functional disability,and symptoms of post-traumatic stress disorder(PTSD)and depression.Results:On average,regardless of their treatment group,participants exhibited a 16%reduction in pain measured by the Brooke Army Medical Center’s Clinic Pain Log[F(1,335)=55.7,P<0.0001]and an 11%reduction in pain-related disability measured by the Million Visual Analog Scale[MVAS:F(1,84)=28.3,P<0.0001]from baseline to the end of treatment,but no one treatment performed better than the other,and the reductions in pain and pain-related disability were largely lost by 1-month follow-up.Symptoms of PTSD and depression did not change significantly as a function of time or group.Conclusions:Findings build on previous work suggesting that traditional Chinese acupuncture and TENS can reduce pain and its functional sequelae without risks associated with pharmacological pain management.The Tennant Biomodulator used on its most basic setting performs as well as these other interventions.Based on the present findings,large,randomized controlled trials on the Tennant Biomodulator are indicated.Future work should test this device using its full range of settings for pain-related psychological health.Trial registration:Clincialtrials.gov(NCT01752010);registered December 14,2012.

文摘We reviewed the literature on transcutaneous electrical nerve stimulation(TENS)used as a therapy for overactive bladder(OAB)symptoms,with a particular focus on:stimulation site,stimuli parameters,neural structures thought to be targeted,and the clinical and urodynamic outcomes achieved.The majority of studies used sacral or tibial nerve stimulation.The literature suggests that,whilst TENS therapy may have neuromodulation effects,patient are unlikely to benefit to a significant extent from a single application of TENS and indeed clear benefits from acute studies have not been reported.In long-term studies there were differences in the descriptions of stimulation intensity,strategy of the therapy,and positioning of the electrodes,as well as in the various symptoms and pathology of the patients.Additionally,most studies were uncontrolled and hence did not evaluate the placebo effect.Little is known about the underlying mechanism by which these therapies work and therefore exactly which structures need to be stimulated,and with what parameters.There is promising evidence for the efficacy of a transcutaneous stimulation approach,but adequate standardisation of stimulation criteria and outcome measures will be necessary to define the best way to administer this therapy and document its efficacy.

文摘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.
文摘AIM:To explore the effectiveness of acupuncture transcutaneous electrical nerve stimulation(Acu-TENS), a non-invasive modality in reduction of rectal discomfort during barostat-induced rectal distension. METHODS:Forty healthy subjects were randomized to receive 45 min of either Acu-TENS or placebo-TENS(no electrical output)over acupuncture points Hegu(largeintestine 4),Neiguan(pericardium 6)and Zusanli(stomach 36).A balloon catheter attached to a dual-drive barostat machine was then inserted into the subjects'rectum.A step-wise(4 mmHg)increase in balloon pressure was induced until maximal tolerable or 48 mmHg.Visual analogue scale and a 5-point subjective discomfort scale(no perception,first per-ception of distension,urge to defecate,discomfort/ pain and extreme pain)were used to assess rectal discomfort at each distension pressure.Blood beta-endorphin levels were measured before,immediately after intervention,at 24 mmHg and at maximal toler- able distension pressure. RESULTS:There was no difference in the demographic data and baseline plasma beta-endorphin levels between the two groups.Perception threshold levels were higher in the Acu-TENS group when compared to the placebo group,but the difference reached statistical significance only at the sensations"urge to defecate"and"pain".The distension pressures recorded at the"urge to defecate"sensation for the Acu-TENS and placebo-TENS groups were 28.0±4.5 mmHg and 24.6±5.7 mmHg,respectively(P=0.043);and the pressures recorded for the"pain"sensation for these two groups were 36.0±4.2 mmHg and 30.5± 4.3 mmHg respectively(P=0.002).Compared to the placebo group,a higher number of participants in the Acu-TENS group tolerated higher distension pressures (>40 mmHg)(65%in Acu-TENS vs 25%in placebo, P=0.02).The plasma beta-endorphin levels of the Acu-TENS group were significantly higher than that of the placebo group at barostat inflation pressure of 24 mmHg(1.31±0.40 ng/mL vs 1.04±0.43 ng/mL,P= 0.044)and at maximal inflation pressure(1.46±0.53 ng/mL vs 0.95±0.38 ng/mL,P=0.003). CONCLUSION:Acu-TENS reduced rectal discomfort during barostat-induced rectal distension and concur-rently associated with a rise in beta-endorphin level.

文摘Objective: To evaluate the effect of transcutaneous electric pulse stimulation (TEPS) on hepatic blood flow and parenchymal microcirculation in patients with fatty liver. Methods: A total of 31 fatty liver volunteer patients were observed in this study. Changes of color Doppler energy (CDE) images before and after TEPS of local points nearby the liver were recorded by using color Doppler ultrasound diagnostic apparatus (ACUSON 128XP/10C). Sum of color pixel area (SCPA), average of color value (ACV) and SCPA×ACV (integral) of the hepatic flow images were analyzed by an image processing system, single blind method and paired t-test. Programmed TEPS (0.5- 150 Hz / 2 000 Hz , 10- 25 V ) was applied to the right Qimen (期门 LR 14)-Jingmen (京门 GB 25), Fuai (腹哀 SP 16)-Ganshu (肝俞 BL 18) respectively for 15 min. Results: Compared with basic values of pretreatment, SCPA, ACV and SCPA×ACV increased significantly (t=2.71, P<0.02; t=3.42, P<0.01; and t=8.15, P<0.001) after TEPS, meaning improvement of hepatic blood flow supply. Conclusion: TEPS of acupoints near the liver can improve hepatic blood flow and hepatic parenchymal microcirculation in patients with fatty liver.

文摘Objective To observe the clinical efficacy of transcutaneous electrical acupoint stimulation(TEAS)combined with warm acupuncture in treating breast cancer associated with upper limb lymphedema(BCRL).Methods This was a retrospective cohort study using a paired control design.Fifty-two BCRL patients were assigned to the control group(27 cases)and the treatment group(25 cases).The patients in the control group were treated with lymphedema comprehensive detumescence treatment(CDT)for 4 weeks,including systematic therapy composed of manual lymphatic drainage,compression bandage,skincare,and functional exercise.The patients in the treatment group were treated with TEAS combined with warm acupuncture based on the control group methods.Each treatment lasted for 30 min and was applied twice a week for 4 weeks.The arm circumference(AC)of different positions of the affected limb and the degree of swelling of the affected limb were evaluated before the first treatment and after the last treatment.The clinical efficacy was evaluated according to the degree of edema before and after treatment.All adverse events during treatment were recorded.Results The patients’AC and the swelling feeling of the affected limb in the treatment group and the control group were both reduced compared with those before treatment.Compared with the control group,AC of the wrist joint transverse stria,the midpoint between the wrist joint transverse stria and the elbow joint transverse stria in the treatment group were significantly reduced(P<0.05).The decrease in AC diameter at the midpoint between the elbow joint transverse stria and the axillary transverse stria was the most significant(P<0.01).The swelling degree of the affected limbs in the treatment group was significantly lower than before treatment,and was significantly lower compared with the control group after treatment(P<0.01).The total effective rate was 72%in the treatment group,significantly higher than that in the control group(55.56%,P<0.05).No serious adverse events occured in either group.Conclusions TEAS combined with warm acupuncture can effectively reduce AC and swelling feeling of the affected limb in patients with BCRL.The effect is better than that of CDT therapy alone.
文摘BACKGROUND Anesthetic drugs used in labor analgesia also paralyze the bladder muscle by blocking the sacral plexus,thereby affecting maternal postpartum spontaneous urination and increasing the risk of postpartum urinary retention(PUR).AIM To analyze the effect of percutaneous electrical stimulation at the Baliao point combined with biofeedback therapy for PUR prevention.METHODS We selected 182 pregnant women who received labor analgesia in obstetrics between June 2022 and December 2023.They were divided into the combined therapy group(transcutaneous electrical stimulation of the Baliao point combined with biofeedback therapy)and the control group(biofeedback therapy alone).The first spontaneous urination time,first postpartum urine volume,bladder residual urine volume,postpartum hemorrhage volume,pre-urination waiting time,PUR incidence,adverse reactions,and the intervention’s clinical efficacy were compared between the two groups.RESULTS The first spontaneous urination time after delivery was more delayed(2.92±1.04 h vs 3.61±1.13 h,P<0.001),with fewer initial postpartum urine(163.54±24.67 mL vs 143.72±23.95 mL,P<0.001),more residual bladder urine(54.81±10.78 mL vs 65.25±13.52 mL,P<0.001),more postpartum bleeding(323.15±46.95 mL vs 348.12±45.03 mL,P=0.001),and longer waiting time for urination(0.94±0.31 min vs 1.29±0.42 min,P<0.001),in the control group than in the combined therapy group.The control group also had higher PUR incidence(4.65%vs 15.85%,P=0.016).Both groups had no adverse reactions,but the clinical total efficacy rate of the intervention was significantly higher in the combined therapy group than in the control group(95.35%vs 84.15%,P=0.016).CONCLUSION Percutaneous electrical stimulation of the Baliao point combined with biofeedback can significantly promote postpartum micturition of parturients with labor analgesia,thereby effectively preventing PUR occurrence.

文摘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.
文摘Objective: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on nausea and vomiting (N&V) induced by patient controlled intravenous analgesia (PCIA) with Tramadol. Methods: Sixty patients who were ready to receive scheduled operation for tumor in the head-neck region and post-operation PCIA, aged 39-65 years, with the physique grades Ⅰ -Ⅱ of ASA, were randomized into two groups, A and B, 30 in each group. The pre-operation medication, induction of analgesia and continuous anesthesia used in the two groups were the same. TEAS on bilateral Hegu (LI4) and Neiguan (PC6) points was intermittently applied to the patients in group A starting from 30 min before analgesia induction to 24 h after operation, and the incidence and score of nausea and vomiting, antiemetic used, visual analogue scores (VAS), and PCIA pressing times in 4 time segments (0-4, 4-8, 8-12 and 12-24 h after the operation was finished) were determined. The same management was applied to patients in Group B, with sham TEAS for control. Results: The incidence and degree of N&V, as well as the number of patients who needed remedial antiemetic in Group A were less than those in Group B. The VAS score and PCIA pressing time were lower in Group A than those in Group B in the corresponding time segments respectively. Conclusion: TEAS could prevent N&V induced by PCIA with Tramadol.
