M...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.展开更多

Acupuncture-like therapies, including electroacupuncture （EA） and transcutaneous electrical acupoint stimulation （TEAS）, become more popular world-wide. Increasing evidence has demonstrated that EA and TEAS are effective in treating gynecological disorders, especially infertility. This present paper describes how to select acupoints for the treatment of infertility from the view of theories of traditional Chinese medicine and how to determine critical parameters of electric pulses of ENTEAS based on results from animal and clinical studies. It summarizes the principles of clinical application of EA/rEAS in treating various kinds of reproductive disorders, such as polycystic ovary syndrome （PCOS）, pain induced by oocyte retrieval, diminished ovarian reserve, embryo transfer, and oligosperrnia/ asthenospermia. The possible underlying mechanisms mediating the therapeutic effects of EA/TEAS in reproductive medicine are also examined.展开更多

METHODS： A single-blinded, randomized experimental design study was conducted. Patients from the North of Taipei Ophthalmology outpatient department diagnosed with intraocular hypertension were selected and were further enrolled if they met the research subject criteria. The patients who met all criteria, and who met no exclusion criteria became the participants. Participants were randomly assigned into the treated group, wherein the TENS electrodes （Qing Ming Medical Device Co., Ltd., New Taipei City, China） were applied with direct current （DC） on the acupoints Pucan （BL 61） and Shenmai （BL 62） for 20 min. The control group received no TENS electrode treatments. Measurements of lOP were taken four times using a pneumotonometer （Clinico Co., Ltd., New Taipei City, China）, before, immediately after, 30 min after, and 60 min after TENS electrode treatments. RESULTS： Eighty-two participants completed the experiment, lOP decreased more in the group treated with DC （P 〈 0.01） than in the control group.The lOPs were not affected by the age of the patients and their usage of medications. CONCLUSION： TENS of acupoints of Pucan （BL 61） and Shenmai （BL 62） could significantly reduce the lOP in patients with glaucoma.展开更多

Two-electrode discriminability is the key to realize high-spatial-resolution TENS, but the neural firing mechanism is not clear yet. The goal of this research is to investigate the neural firing patterns under two-electrode stimulation and to reveal the potential mechanisms. A three-dimensional(3 D) model is established by incorporating Aβ fiber neuron clusters into a layered forearm structure. The diameters of the stimulating electrodes are selected as 5, 7, 9 and 12 mm, and the two-electrode discrimination distance(TEDD) is quantified. It is found that a distant TEDD is obtained for a relatively large electrode size, and 7 mm is suggested to be the optimal diameter of stimulating electrodes. The present study reveals the neural firing patterns under two-electrode stimulation by the 3 D TENS model. In order to discriminate individual electrodes under simultaneous stimulation, no crosstalk of activated Aβ fibers exists between two electrodes. This research can further guide the optimization of the electrode-array floorplan.展开更多

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Transcutaneous electrical acupoint stimulation(TEAS)is a kind of physical therapy that use electric cur-rent through the electrodes placed on the surface of acupoints to produce clinical effects in the human body,which is characterized by less adverse reaction and convenient operation.It has been widely used in the treatment of various diseases.This review introduces six major clinical applications of TEAS,named analgesia,regulation of gastrointestinal function,improvement of reproductive function,enhancement of cognitive function,promotion of limb function recovery and relief of fatigue.Besides,TEAS has been ap-plied to the treatment of other chronic diseases such as hypertension and diabetes,achieving satisfactory clinical effects.However,two crucial challenges are encountered in the development of TEAS.One is the lack of standardization in the selection of parameters such as waveform,frequency,intensity and stimula-tion duration.The other is the limitation on the flexibility in the acupoint selection.This review analyzes key issues that need to be addressed in the current clinical application of TEAS,such as the selection of parameters and acupoints,and this review provides a certain reference value for optimizing regimens of TEAS and promoting its development and application.

文摘Objective:To evaluate the efficacy and safety of transcutaneous electrical acupoint stimulation(TEAS)for muscle atrophy in patients with immobilization after surgical fixation of foot and ankle fractures.Methods:This was a two-arm randomized controlled trial wherein 80 patients were recruited and divided into control(n=40)and intervention(n=40)groups.The control group received conventional orthopedic treatment,whereas the intervention group received TEAS and conventional treatment.The intervention group received TEAS 3 times a week for 30 min each time for 8 weeks.The primary out-comes were muscle thickness(MT)and cross-sectional area(CSA)of the rectus femoris and gastroc-nemius muscles,whereas the secondary outcome measure was echo intensity(EI).Data were collected before the fixation operations(baseline assessment)and 4 and 8 weeks after intervention.Results:Compared with baseline,the MT and CSA were reduced in both groups by the end of treatment,whereas EI increased in both groups.At week 4,the reduction in the rectus femoris CSA in the inter-vention group was significantly lower than that in the control group(P=0.02);however,the between-group differences in the MT and EI(all P>0.05)were not significant.No serious adverse events were observed in either group.Conclusion:Our study showed that TEAS can improve muscle atrophy by attenuating the decline in the muscle CSA.Because this was only a pilot trial,subsequent studies will need longer follow-ups and larger sample sizes.
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Objective:To explore the efficacy of auricular acupuncture combined with transcutaneous electrical nerve stimulation(TENS)and nonsteroidal anti-inflammatory drugs(NSAIDs)in alleviating postpartum uterine pain.Methods:A total of 501 postpartum women with uterine pain were randomly divided into an experimental group(n=250)and a control group(n=251).The control group received oral NSAIDs(such as ibuprofen sustained-release capsules,diclofenac sodium suppositories,etc.),while the experimental group received auricular acupuncture and TENS in addition to the NSAIDs.The clinical efficacy,pain intensity,and vaginal bleeding volume of the two groups were observed.Results:The total effective rate in the experimental group(93.20%)was significantly higher than that in the control group(73.20%)(P<0.001).The NRS scores in the experimental group were lower than those in the control group after the intervention,and the bleeding volume within 24 h and 48 h after the intervention was also less than that in the control group,with significant differences(all P<0.001).Conclusion:Auricular acupuncture combined with TENS and NSAIDs for the treatment of postpartum uterine pain is safe and effective,can significantly reduce pain and vaginal bleeding,and is worthy of clinical promotion.
文摘Objective:A comprehensive meta-analysis based on the latest randomized controlled trials(RCTs)was conducted to investigate the effects of transcutaneous electrical nerve stimulation(TENS)on patients undergoing treatment after inguinal hernia surgery.Methods:A detailed search of Embase,PubMed,Web of Science,and the Cochrane Library was performed for RCTs investigating the use of TENS during inguinal hernia surgery up to September 28,2021.The Cochrane tool was applied to assess the risk of bias in the included studies.Results:Seven eligible RCTs with a total of 379 cases were included.The meta-analysis showed a mean difference(MD)in VAS of-1.61[95%CI:-2.20-1.02,P<0.00001]at 2 hours post-operation,VAS MD=-1.33 at 4 hours post-operation[95%CI:-2.84-0.18,P=0.09],VAS MD=-2.36 at 8 hours post-operation[95%CI:-4.04-0.69,P=0.006],and VAS MD=-1.75 at 24 hours post-operation[95%CI:-2.64-0.85,P=0.0001].The cortisol level MD at 24 hours post-operation was-52.56[95%CI:-168.8-63.76,P=0.38].Conclusion:TENS significantly reduces postoperative pain following inguinal hernia surgery and promotes patient recovery.TENS is recommended for patients undergoing inguinal hernia surgery.However,further high-quality studies are needed to confirm additional effects.
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:Gastroesophageal reflux disease(GERD)is a common disorder.Overall,≤35%of GERD patients fail the standard dose of proton-pump-inhibitor(PPI)treatment.Due to the high prevalence and low satisfaction rate with treatment failure,there is an unmet need for new treatment.Our aim was to evaluate whether the use of the transcutaneous electrical stimulation system(TESS)can reduce esophageal-acid exposure in GERD patients unresponsive to standard-dose PPI.Methods:We enrolled 10 patients suffering from heartburn and regurgitation with an abnormal esophageal-acid exposure(off PPIs)who failed standard-dose PPI.After the placement of a wireless esophageal pH capsule,all patients were treated with TESS.The primary end point was the reduction in the baseline(pretreatment)24-hour percent total time pH<4 and/or DeMeester score by 50%.Results:Seven GERD patients(five females and two males,aged 49.3610.1 years)completed the study.At baseline,the mean percent total time pH<4 was 12.064.9.Following TESS,the mean percent total time pH<4 dropped to 5.563.4,4.562.6,3.762.9,and 4.462.5 on Days 1,2,3,and 4,respectively.At baseline,the mean DeMeester score was 39.0618.5.After TESS,the mean DeMeester score dropped to 15.869.2,13.266.8,11.269.4,and 12.066.8 on Days 1,2,3,and 4,respectively.Conclusion:TESS is a safe and potentially effective modality in reducing esophageal-acid exposure in GERD patients unresponsive to standard-dose PPI.A larger and prospective controlled study is needed to verify these preliminary results.

文摘Abstract： With the rapid development of assisted reproductive technology, various reproductive disorders have been effectively addressed. Acupuncture-like therapies, including electroacupuncture （EA） and transcutaneous electrical acupoint stimulation （TEAS）, become more popular world-wide. Increasing evidence has demonstrated that EA and TEAS are effective in treating gynecological disorders, especially infertility. This present paper describes how to select acupoints for the treatment of infertility from the view of theories of traditional Chinese medicine and how to determine critical parameters of electric pulses of ENTEAS based on results from animal and clinical studies. It summarizes the principles of clinical application of EA/rEAS in treating various kinds of reproductive disorders, such as polycystic ovary syndrome （PCOS）, pain induced by oocyte retrieval, diminished ovarian reserve, embryo transfer, and oligosperrnia/ asthenospermia. The possible underlying mechanisms mediating the therapeutic effects of EA/TEAS in reproductive medicine are also examined.

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 investigate the effects of transcutaneous electrical nerve stimulation （TENS） through acupoints on the intraocular pressure （lOP） in patients with glaucoma. METHODS： A single-blinded, randomized experimental design study was conducted. Patients from the North of Taipei Ophthalmology outpatient department diagnosed with intraocular hypertension were selected and were further enrolled if they met the research subject criteria. The patients who met all criteria, and who met no exclusion criteria became the participants. Participants were randomly assigned into the treated group, wherein the TENS electrodes （Qing Ming Medical Device Co., Ltd., New Taipei City, China） were applied with direct current （DC） on the acupoints Pucan （BL 61） and Shenmai （BL 62） for 20 min. The control group received no TENS electrode treatments. Measurements of lOP were taken four times using a pneumotonometer （Clinico Co., Ltd., New Taipei City, China）, before, immediately after, 30 min after, and 60 min after TENS electrode treatments. RESULTS： Eighty-two participants completed the experiment, lOP decreased more in the group treated with DC （P 〈 0.01） than in the control group.The lOPs were not affected by the age of the patients and their usage of medications. CONCLUSION： TENS of acupoints of Pucan （BL 61） and Shenmai （BL 62） could significantly reduce the lOP in patients with glaucoma.

文摘Transcutaneous electrical nerve stimulation(TENS) has been widely used for sensory feedback which is a key consideration of improving the performance of prosthetic hands. Two-electrode discriminability is the key to realize high-spatial-resolution TENS, but the neural firing mechanism is not clear yet. The goal of this research is to investigate the neural firing patterns under two-electrode stimulation and to reveal the potential mechanisms. A three-dimensional(3 D) model is established by incorporating Aβ fiber neuron clusters into a layered forearm structure. The diameters of the stimulating electrodes are selected as 5, 7, 9 and 12 mm, and the two-electrode discrimination distance(TEDD) is quantified. It is found that a distant TEDD is obtained for a relatively large electrode size, and 7 mm is suggested to be the optimal diameter of stimulating electrodes. The present study reveals the neural firing patterns under two-electrode stimulation by the 3 D TENS model. In order to discriminate individual electrodes under simultaneous stimulation, no crosstalk of activated Aβ fibers exists between two electrodes. This research can further guide the optimization of the electrode-array floorplan.
