ABSTRACT
OBJECTIVE: To investigate the effects of visualized precision electrophysiological diagnosis and transcutaneous low-frequency electrical stimulation (TES) on hypoxia-induced ED in high-altitude areas. METHODS: This study included 152 ED patients from high-altitude hypoxic areas treated by TES based on the parameters obtained from visualized precision electrophysiological diagnosis. We followed up the patients for 1 to 3 months and compared their IIEF-5 scores, nocturnal penile tumescence and rigidity (NPTR) and infrared thermal metabolic technology (TMT)-based temperature of the whole body and diseased parts before and after treatment. RESULTS: All the patients successfully completed 1 to 3 courses of TES. There were no statistically significant differences in the IIEF-5 scores (P<0.05) and penile tip optimal erection rigidity and duration (P<0.01) of the patients before and after treatment. TMT images indicated a temperature change of >1.5 â in the penis and bilateral inguinal regions after treatment, suggesting the effectiveness of electrical stimulation. No recurrence was observed during the follow-up. CONCLUSION: TES based on the parameters obtained from visualized precision electrophysiological diagnosis has a definite effect on hypoxia-induced ED by enhancing oxygen supply to the penile corpus cavernosum and improving its function and structure.

Objective. Phantom limb pain (PLP) is debilitating and affects over 70% of people with lower-limb amputation. Other neuropathic pain conditions correspond with increased spinal excitability, which can be measured using reflexes andF-waves. Spinal cord neuromodulation can be used to reduce neuropathic pain in a variety of conditions and may affect spinal excitability, but has not been extensively used for treating PLP. Here, we propose using a non-invasive neuromodulation method, transcutaneous spinal cord stimulation (tSCS), to reduce PLP and modulate spinal excitability after transtibial amputation.Approach. We recruited three participants, two males (5- and 9-years post-amputation, traumatic and alcohol-induced neuropathy) and one female (3 months post-amputation, diabetic neuropathy) for this 5 d study. We measured pain using the McGill Pain Questionnaire (MPQ), visual analog scale (VAS), and pain pressure threshold (PPT) test. We measured spinal reflex and motoneuron excitability using posterior root-muscle (PRM) reflexes andF-waves, respectively. We delivered tSCS for 30 min d-1for 5 d.Main Results. After 5 d of tSCS, MPQ scores decreased by clinically-meaningful amounts for all participants from 34.0 ± 7.0-18.3 ± 6.8; however, there were no clinically-significant decreases in VAS scores. Two participants had increased PPTs across the residual limb (Day 1: 5.4 ± 1.6 lbf; Day 5: 11.4 ± 1.0 lbf).F-waves had normal latencies but small amplitudes. PRM reflexes had high thresholds (59.5 ± 6.1µC) and low amplitudes, suggesting that in PLP, the spinal cord is hypoexcitable. After 5 d of tSCS, reflex thresholds decreased significantly (38.6 ± 12.2µC;p< 0.001).Significance. These preliminary results in this non-placebo-controlled study suggest that, overall, limb amputation and PLP may be associated with reduced spinal excitability and tSCS can increase spinal excitability and reduce PLP.

Upper limb amputation severely affects the quality of life of individuals. Therefore, developing closed-loop upper-limb prostheses would enhance the sensory-motor capabilities of the prosthetic user. Considering design priorities based on user needs, the restoration of sensory feedback is one of the most desired features. This study focuses on employing Transcutaneous Electrical Nerve Stimulation (TENS) as a non-invasive somatotopic stimulation technique for restoring somatic sensations in upper-limb amputees. The aim of this study is to propose two encoding strategies to elicit force and slippage sensations in transradial amputees. The former aims at restoring three different levels of force through a Linear Pulse Amplitude Modulation (LPAM); the latter is devoted to elicit slippage sensations through Apparent Moving Sensation (AMS) by means of three different algorithms, i.e. the Pulse Amplitude Variation (PAV), the Pulse Width Variation (PWV) and Inter-Stimulus Delay Modulation (ISDM). Amputees had to characterize perceived sensations and to perform force and slippage recognition tasks. Results demonstrates that amputees were able to correctly identify low, medium and high levels of force, with an accuracy above the 80% and similarly, to also discriminate the slippage moving direction with a high accuracy above 90%, also highlighting that ISDM would be the most suitable method, among the three AMS strategies to deliver slippage sensations. It was demonstrated for the first time that the developed encoding strategies are effective methods to somatotopically reintroduce in the amputees, by means of TENS, force and slippage sensations.

Background: Obesity is widely recognized for its role in predisposing individuals to a spectrum of chronic health conditions. Emerging preliminary evidence points to the potential benefits of low-frequency transcutaneous electrical nerve stimulation (Lo-TENS) in enhancing various health outcomes among those with obesity and associated disorders. Objective: This systematic review was designed to assess the effectiveness of Lo-TENS for managing obesity and its related chronic diseases. Methods: For this systematic review, we included randomized controlled trials that evaluated the impact of Lo-TENS on individuals with obesity and its associated chronic diseases. Results: Eight trials encompassing 671 participants and spanning three unique populations: essential hypertension (EH), type 2 diabetes mellitus (T2DM), and obesity were deemed eligible for inclusion in this review. Compared to baseline measurements, Lo-TENS demonstrated a tendency to positively affect blood pressure in individuals with EH and metabolic parameters in those with T2DM. Nonetheless, the efficacy of Lo-TENS in treating obesity is not yet clear when contrasted with a no-intervention control group. When compared with other intervention modalities, three of the trials reported less favorable results. Conclusions: Although Lo-TENS did not consistently surpass other treatments or yield substantial improvements, it generally provided greater benefits than the majority of placebo controls. This suggests that Lo-TENS could potentially serve as a beneficial adjunctive therapy in the management of obesity and its associated conditions. However, given the limited number of trials assessed, the elevated risk of bias within these studies, and the scarce evidence currently available, it is too early to reach definitive conclusions. Caution should be exercised when interpreting the current findings. There is an imperative for further high-quality research to thoroughly investigate and substantiate the efficacy of Lo-TENS in relation to obesity and its related disorders.

INTRODUCTION: Long head of biceps brachii tendinopathy, a frequent source of anterior shoulder pain, may lead to discomfort and diminished function. The objective of this study is to assess the efficacy of dry needling and transcutaneous electrical nerve stimulation in these patients. PATIENTS AND METHODS: Thirty patients were randomized into dry needling and transcutaneous electrical nerve stimulation groups and assessed before treatment, 8 and 15 days after treatment using a visual analogue scale, shoulder pain and disability index, pressure pain threshold, tissue hardness, and biceps peritendinous effusion. RESULTS: Both treatments significantly reduced the visual analogue scale in immediate (p < 0.001), short-term (p < 0.01), and medium-term effects (p < 0.01). Dry needling outperformed transcutaneous electrical nerve stimulation for the pain (p < 0.01) and disability (p < 0.03) subscales of the shoulder pain and disability index in the short-term and medium-term effects, respectively. Pressure pain threshold increased after both treatments but didn't last beyond 8 days. Neither treatment showed any improvements in tissue hardness of the long head of biceps brachii muscle. Notably, only the dry needling group significantly reduced biceps peritendinous effusion in both short-term and medium-term effects (p < 0.01). CONCLUSIONS: Dry needling showed non-inferior results to transcutaneous electrical nerve stimulation in reducing pain and disability and demonstrated even superior results in reducing biceps peritendinous effusion (see Graphical Abstract). TRIAL REGISTRATION: The Institutional Review Board of the China Medical University Hospital (CMUH107-REC2-101) approved this study, and it was registered with Identifier NCT03639454 on ClinicalTrials.gov.

BACKGROUND: Perioperative neurocognitive disorder (PND) is a critical concern for older patients undergoing cardiac surgery, impacting cognitive function and quality of life. Electroacupuncture and transcutaneous electrical acupoint stimulation (TEAS) hold promise for mitigating PND. This protocol outlines a systematic review and meta-analysis to thoroughly assess the efficacy of electroacupuncture and TEAS in older patients undergoing cardiac surgery with PND, providing up-to-date evidence for PND prevention and treatment. OBJECTIVE: This study aimed to thoroughly assess the efficacy of electroacupuncture and TEAS in older patients undergoing cardiac surgery with PND, providing up-to-date evidence for PND prevention and treatment. METHODS: A comprehensive and systematic approach will be used to identify eligible studies from a diverse range of electronic databases, including 9 major sources such as PubMed (NLM) and Cochrane (Wiley), as well as 2 clinical trial registration websites. These studies will focus on investigating the effects of electroacupuncture and TEAS on PND in older patients undergoing cardiac surgery. The study selection will adhere to the criteria outlined in the patient, intervention, comparison, outcome, and studies (PICOS) format. Data extraction will be carried out by 2 independent researchers (YP and LS), using established tools to evaluate the risk of bias. The primary outcome will be PND incidence, with secondary outcomes including Mini Mental State Examination scores, neuron-specific enolase, S100ß, interleukin-1ß, interleukin-6, tumor necrosis factor-α, time to first flatus, first defecation, bowel sound recovery, and hospitalization duration to be selectively reported. Adverse events linked to acupuncture, such as bleeding, needle site pain, and local reactions, rather than serious adverse events, will also be considered. Meta-analysis will be performed using appropriate statistical methods to assess the overall effect of electroacupuncture and TEAS on PND prevention, treatment, or other relevant outcomes. The Cochrane Collaboration Risk of Bias tool will be used for assessment, and data synthesis will be executed using the RevMan 5.4 software (Cochrane). RESULTS: We plan to summarize the eligible studies through the use of a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flowchart. The findings will be showcased in the form of a summary table of evidence. Figures and forest plots will be used to illustrate the outcomes of the meta-analysis. CONCLUSIONS: The impacts of electroacupuncture and TEAS interventions on PND in older patients undergoing cardiac surgery have not yet been established. This protocol addresses a critical gap by thoroughly assessing electroacupuncture and TEAS for PND in older patients undergoing cardiac surgery, enhancing understanding of nonpharmacological interventions, and guiding future research and clinical practices in this field. Its strength lies in rigorous methodology, including comprehensive search strategies, independent review processes, and thorough assessments of the risk of bias.

BACKGROUND: Radiculopathy can cause pain and numbness along a pinched nerve. OBJECTIVE: To investigate how people with cervical radiculopathy respond to intense cervical traction in terms of depression, sleeplessness, and quality of life (QoL). METHODS: Two equal groups of forty male patients with unilateral cervical radiculopathy were randomly assigned. In addition to transcutaneous electrical nerve stimulation (TENS) and other treatments, twenty individuals in group I received mechanical cervical traction. Group II consisted of twenty individuals who received only TENS treatment. Before and after treatment, every participant completed the Arabic versions of the Hospital Anxiety and Depression Scale (HADS), the Insomnia Severity Index (ISI), and Short-Form 36 Health Survey (SF-36). RESULTS: While there was no significant difference in group II, there was a significant decline in group I visual analog scale (Pâ=â0.001), depression subscale of the hospital anxiety and depression score (Pâ=â0.001), and ISI (Pâ=â0.001). Eight domains of SF-36 showed a significant increase in group I. These domains included physical functioning (Pâ=â0.001), role limitations due to physical health (Pâ=â0.001), role limitations due to emotional problems (Pâ=â0.001), and energy (Pâ=â0.001). In group II, there was a non-significant increase nevertheless. CONCLUSION: Cervical traction improved individuals' QoL, depression, and insomnia, suggesting the effectiveness of it with TENS for cervical radiculopathy patients.

Background: The effect of transcutaneous electrical nerve stimulation (TENS) on pain and impression of change was assessed during a 2.5-hour intervention on the first postoperative days following hip surgery in a randomized, single-blinded, placebo-controlled trial involving 30 patients. Methods: Mixed-frequency TENS (2 Hz/80 Hz) was administered using specially designed pants integrating modular textile electrodes to facilitate stimulation both at rest and during activity. The treatment outcome was assessed by self-reported pain Numerical Rating Scale (NRS) and Patient Global Impression of Change (PGIC) scores at four time points. The ability to perform a 3-meter walk test and the use of analgesics were also evaluated. Group comparison and repeated-measure analysis were carried out using nonparametric statistics. Results: The active TENS group exhibited significantly higher PGIC scores after 30 minutes, which persisted throughout the intervention (all p ≤ 0.001). A reduction in NRS appeared after one hour of active TENS, persisting throughout the intervention (all p ≤ 0.05). The median group differences in pain ratings were greater than the minimum clinically important difference, and the analysis of pain trajectories confirmed clinical significance at the individual level. Moreover, patients in the active TENS group were more likely able to perform a 3-meter walk test by the end of the intervention (p = 0.04). Analysis of the opioid-sparing effect of TENS was inconclusive (p = 0.066). No postoperative surgical complications or TENS-related side effects were observed during the study. Conclusion: Mixed-frequency TENS integrated in pants could potentially be an interesting addition to the arsenal of treatments for multimodal analgesia following hip surgery. This trial is registered with NCT05678101.

Transcutaneous spinal stimulation (TSS) is a promising rehabilitative intervention to restore motor function and coordination for individuals with spinal cord injury (SCI). The effects of TSS are most commonly assessed by evaluating muscle response to stimulation using surface electromyography (sEMG). Given the increasing use of robotic devices to deliver therapy and the emerging potential of hybrid rehabilitation interventions that combine neuromodulation with robotic devices, there is an opportunity to leverage the on-board sensors of the robots to measure kinematic and torque changes of joints in the presence of stimulation. This paper explores the potential for robotic assessment of the effects of TSS delivered to the cervical spinal cord. We used a four degree-of-freedom exoskeleton to measure the torque response of upper limb (UL) joints during stimulation, while simultaneously recording sEMG. We analyzed joint torque and electromyography data generated during TSS delivered over individual sites of the cervical spinal cord in neurologically intact participants. We show that site-specific effects of TSS are manifested not only by modulation of the amplitude of spinally evoked motor potentials in UL muscles, but also by changes in torque generated by individual UL joints. We observed preferential resultant action of proximal muscles and joints with stimulation at the rostral site, and of proximal joints with rostral-lateral stimulation. Robotic assessment can be used to measure the effects of TSS, and could be integrated into complex control algorithms that govern the behavior of hybrid neuromodulation-robotic systems.

BACKGROUND: Transcutaneous spinal stimulation (TSS) and neuromuscular electrical stimulation (NMES) can facilitate self-assisted standing in individuals with paralysis. However, individual variability in responses to each modality may limit their effectiveness in generating the necessary leg extension force for full body weight standing. To address this challenge, we proposed combining TSS and NMES to enhance leg extensor muscle activation, with optimizing timing adjustment to maximize the interaction between the two modalities. METHODS: To assess the effects of TSS and NMES on knee extension and plantarflexion force, ten neurologically intact participants underwent three conditions: (1) TSS control, (2) NMES control, and (3) TSS + NMES. TSS was delivered between the T10 and L2 vertebrae, while NMES was delivered to the skin over the right knee extensors and plantarflexors. TSS and NMES were administered using a 15 Hz train of three 0.5 ms biphasic pulses. During the TSS + NMES condition, the timing between modalities was adjusted in increments of » the interval within a 15 Hz frequency, i.e., 66, 49.5, 33, 16.5, and 1 ms. RESULTS: NMES combined with TSS, produced synergistic effects even on non-targeted muscle groups, thereby promoting leg extension across multiple joints in the kinematic chain. The sequence of NMES or TSS trains relative to each other did not significantly impact motor output. Notably, a delay of 16.5 to 49.5 ms between interleaved TSS and NMES pulses, each delivered at 15 Hz, results in more robust and synergistic responses in knee extensors and plantarflexors. CONCLUSIONS: By adjusting the timing between TSS and NMES, we can optimize the combined use of these modalities for functional restoration. Our findings highlight the potential of integrated TSS and NMES protocols to enhance motor function, suggesting promising avenues for therapeutic applications, particularly in the rehabilitation of individuals with SCI.

PURPOSE OF REVIEW: The aim of this article is to review considerations and efficacy of third-line treatments for pediatric non-neurogenic bladder dysfunction, including Botulinum toxin A (BoTNA), Posterior Tibial Nerve Stimulation (PTNS), and Sacral Neuromodulation (SNM). RECENT FINDINGS: Federal Drug Administration approval for use of beta-3-agonists in overactive detrusor activity in pediatric patients may provide an additional step prior to third-line therapies. New long-term data on pediatric SNM efficacy, complications, and revision rates will provide valuable information for counseling families. BoTNA offers a safe and efficacious treatment to decrease detrusor contractility and improve bladder capacity but is limited by the half-life of BoNTA agent. Percutaneous or transcutaneous PTNS offers improved voided volumes or cure in some patients but is time-intensive. SNM can be utilized in a variety of LUTD pathology with high success rate and cure but should consider cumulative anesthetic and fluoroscopic exposures for battery replacements and re-positioning for patient growth.

BACKGROUND: Low anterior resection syndrome (LARS) is a distressing condition that affects approximately 25-80% of patients following surgery for rectal cancer. LARS is characterized by debilitating bowel dysfunction symptoms, including fecal incontinence, urgent bowel movements, and increased frequency of bowel movements. Although biofeedback therapy has demonstrated effectiveness in improving postoperative rectal control, the research results have not fulfilled expectations. Recent research has highlighted that stimulating the pudendal perineal nerves has a superior impact on enhancing pelvic floor muscle function than biofeedback alone. Hence, this study aims to evaluate the efficacy of a combined approach integrating biofeedback with percutaneous electrical pudendal nerve stimulation (B-PEPNS) in patients with LARS through a randomized controlled trial (RCT). METHODS AND ANALYSIS: In this two-armed multicenter RCT, 242 participants with LARS after rectal surgery will be randomly assigned to undergo B-PEPNS (intervention group) or biofeedback (control group). Over 4 weeks, each participant will undergo 20 treatment sessions. The primary outcome will be the LARS score. The secondary outcomes will be anorectal manometry and pelvic floor muscle electromyography findings and the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire-Colorectal 29 (EORTC QLQ-CR29) scores. Data will be collected at baseline, post-intervention (1 month), and follow-up (6 months). DISCUSSION: We anticipate that this study will contribute further evidence regarding the efficacy of B-PEPNS in alleviating LARS symptoms and enhancing the quality of life for patients following rectal cancer surgery.

The occurrence of wound infection following a Caesarean section procedure poses a substantial clinical obstacle. Transcutaneous Electrical Nerve Stimulation (TENS) has been identified as a promising supplementary treatment option for improving the healing process and decreasing the incidence of infections. This study assessed the efficacy of TENS therapy in the postoperative care of patients who have had Caesarean section. We randomly assigned a total of 108 women who had Caesarean sections to either a TENS group (n = 54) or control (n = 54). The TENS therapy was provided twice daily for a duration of 30 min for the period of 14 days following the surgery. The main measure of interest in this study was the occurrence of wound infection during 30-day period. Additionally, secondary measures included the rate of wound healing, levels of pain experienced and level of patient satisfaction. In comparison to the control (22.2%, p < 0.05), the TENS group had notably reduced occurrence of wound infection, with the rate of 7.4%. TENS group had superior wound healing results, as measured by REEDA scale, at 7 days (2.1 ± 0.8 vs. 2.5 ± 1.0, p < 0.04), 14 days (1.2 ± 0.5 vs. 1.9 ± 0.7, p < 0.05) and 30 days (0.3 ± 0.5 vs. 0.7 ± 0.6, p < 0.05). Furthermore, TENS group had reduced pain levels on the Visual Analog Scale (VAS) at all evaluation intervals (p < 0.05). TENS group exhibited significantly higher levels of patient satisfaction, as evidenced by 64.8% of participants rating high satisfaction, in contrast to 40.7% in the control group (p < 0.05). The incidence of adverse effects was found to be minor, as indicated by a skin irritation rate of 3.7% and reported discomfort rate of 1.9% at the electrode location. TENS therapy effectively decreased the occurrence of post-Caesarean wound infections, expedited the healing process and enhanced pain control. This treatment was well-received by patients and had little negative consequences. The aforementioned results provided evidence in favour of incorporating TENS into post-Caesarean care regimens, which may have significant consequences for improving patient outcomes and maximizing healthcare resources.

BACKGROUND: Previous work demonstrated the beneficial effect of T6 dermatomal stimulation by the percutaneous method in managing obesity. However, a simple, cost-effective, and feasible intervention stimulating the dermatome can be a potential solution for obesity care. OBJECTIVE: The objective of this study was to find the effect of transcutaneous electrical nerve stimulation (TENS) of T6 dermatome on appetite and weight loss in obese individuals. MATERIAL AND METHODS: In this prospective single-arm experimental study, 20 obese patients received TENS treatment of T6 dermatome for 30 min, once a week and for 12 weeks. Outcome measures such as appetite level in the visual analog scale (VAS), weight in kg, and basal metabolic index (BMI) in kg/m2 were assessed at baseline, 12 weeks -post-intervention, and at 8 weeks of follow-up. RESULTS: A statistically significant difference in all the variables was found from baseline to 12 weeks of intervention (P < 0.001) and maintained till 8 weeks of follow-up. From pre- to post-treatment, the effect size for appetite reduction was large (>1) while for weight and BMI loss was (0.14, 0.16), respectively small. Additionally, a weak correlation was found between pre- and follow-up appetite and weight loss (r = 0.25, P = 0.294). CONCLUSIONS: Twelve weeks of TENS treatment of T6 dermatome showed a positive effect in reducing appetite with sustained reduction up to 8 weeks of follow-up even after completion of the intervention. However, in the absence of dietary modification, TENS treatment was associated with low effect sizes weight and BMI loss.

(1) Background: Restoring arm and hand function is one of the priorities of people with cervical spinal cord injury (cSCI). Noninvasive electromagnetic neuromodulation is a current approach that aims to improve upper-limb function in individuals with SCI. The aim of this study is to review updated information on the different applications of noninvasive electromagnetic neuromodulation techniques that focus on restoring upper-limb functionality and motor function in people with cSCI. (2) Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were used to structure the search protocol. A systematic review of the literature was performed in three databases: the Cochrane Library, PubMed, and Physiotherapy Evidence Database (PEDro). (3) Results: Twenty-five studies were included: four were on transcranial magnetic stimulation (TMS), four on transcranial direct current stimulation (tDCS), two on transcutaneous spinal cord stimulation (tSCS), ten on functional electrical stimulation (FES), four on transcutaneous electrical nerve stimulation (TENS), and one on neuromuscular stimulation (NMS). The meta-analysis could not be completed due to a lack of common motor or functional evaluations. Finally, we realized a narrative review of the results, which reported that noninvasive electromagnetic neuromodulation combined with rehabilitation at the cerebral or spinal cord level significantly improved upper-limb functionality and motor function in cSCI subjects. Results were significant compared with the control group when tSCS, FES, TENS, and NMS was applied. (4) Conclusions: To perform a meta-analysis and contribute to more evidence, randomized controlled trials with standardized outcome measures for the upper extremities in cSCI are needed, even though significant improvement was reported in each non-invasive electromagnetic neuromodulation study.

BACKGROUND: Abdominal pain due to menses (primary dysmenorrhea) is an extremely pervasive and debilitating symptom affecting up to 90% of menstruating individuals. OBJECTIVE: The objective of this randomized control trial was to investigate the effect of a commercial transcutaneous electrical nerve stimulation unit, Therabody PowerDot® (Therabody Inc., Los Angeles) on dysmenorrhea compared with non-steroidal anti-inflammatory drug use. DESIGN: This was a randomized cross-over study. METHODS: A total of 47 participants agreed to participate in the study, with 34 completing it. Participants completed treatments across three consecutive menstrual cycles in randomized order: single-unit transcutaneous electrical nerve stimulation (Uno), dual unit transcutaneous electrical nerve stimulation (Duo), and non-steroidal anti-inflammatory drug use (Control). Upon onset of dysmenorrhea, participants applied transcutaneous electrical nerve stimulation to their abdomen for a minimum of 30 min. Control participants were instructed to take non-steroidal anti-inflammatory drugs as needed. Surveys were used to record pain before and after treatment. We hypothesized that the PowerDot would decrease self-reported pain scores, and decrease non-steroidal anti-inflammatory drug consumption during menses. RESULTS: Participants experienced a statistically and clinically significant reduction in pain during the Control (-3.52 ± 1.9), Uno (-2.10 ± 1.6), and Duo (-2.19 ± 1.7) cycles (p < 0.001). The doses of non-steroidal anti-inflammatory drugs consumed during the Control cycle (3.5 ± 2.6), was significantly different as compared with that of Uno (1.5 ± 3.0), or Duo (1.1 ± 2.6) (p = 0.004). CONCLUSIONS: Use of a commercial transcutaneous electrical nerve stimulation unit results in significant decrease in pain. Although not as robust as the relief in pain induced by non-steroidal anti-inflammatory drugs, the adverse events of transcutaneous electrical nerve stimulation are minimal in comparison. Therefore, transcutaneous electrical nerve stimulation appears to be a viable alternative to pain relief from dysmenorrhea. CLINICAL TRIAL REGISTRATION: NCT05178589.
The role of electrical signals for period pain reliefMenstruation, also known as the period, is a cyclicly occurring event in people who are assigned female at birth. Often, the period is associated with abdominal pain that can be debilitating for many. This abdominal pain is typically treated using over-the-counter medications, such as ibuprofen; however, there several noted side effects that can arise from use of such medication. As such, this study aimed to understand if a device (Therabody PowerDot®; Therabody Inc., Los Angeles) that sends an electrical current to pads placed over the abdomen, much like a heating pad, could be used to decrease pain during the period to a similar level as medication. The research team studied three consecutive periods with differing setups: a single, elongated pad, placed on the lower abdomen (Uno), two circular pads placed on the lower abdomen (Duo), or no use of the device, only medication (Control). The researchers analyzed data from 34 individuals. It was found that all three cycles experienced a significant decrease in pain, with the control cycle having a greater decrease in pain than both the Uno and Duo. This study suggests that the electrical stimulation used here can greatly decrease pain during the period, though not as substantial as medication.

Aim: Despite the growing evidence supporting the use of peripheral nerve stimulation (PNS) for cancer pain in adults, it is underutilized in the pediatric oncology population.Method: We describe the use of temporary, percutaneous PNS for pain management in pediatric patients suffering from cancer related pain.Results: Two adolescent patients underwent an ultrasound-guided suprascapular nerve PNS placement utilizing the percutaneous 60-day therapy system. Both patients reported approximately 60% pain relief during the therapy, as well as up to 90 days post lead removal.Conclusion: PNS may play a crucial role in the pediatric oncology population. Further studies are warranted to investigate the efficacy and safety of PNS for various cancer-related pain conditions in pediatric populations.
Peripheral nerve stimulator is a device that uses electrical impulses to stimulate the nerves that send pain signals to the brains. This device may be useful in treating pain in cancer patients. We highlight two pediatric cancer patients that had pain relief using a specific type of peripheral nerve stimulator that is removed after 60 days. It is thought that pain relief is sustained even after removing the stimulator by altering the pain signals to the brain. This treatment may serve an important role in treating pediatric cancer pain.

Percutaneous neuromodulation is emerging as a promising therapeutic approach for atrial fibrillation (AF). This article explores techniques such as ganglionated plexi (GP) ablation, and vagus nerve stimulation, pinpointing their potential in modulating AF triggers and maintenance. Noninvasive methods, such as transcutaneous low-level tragus stimulation, offer innovative treatment pathways, with early trials indicating a significant reduction in AF burden. GP ablation may address autonomic triggers, and the potential for GP ablation in neuromodulation is discussed. The article stresses the necessity for more rigorous clinical trials to validate the safety, reproducibility, and efficacy of these neuromodulation techniques in AF treatment.

Transcutaneous vagus nerve stimulation (tVNS) is a promising technique for enhancing cognitive performance and skill acquisition. Yet, its efficacy for enhancing learning rate and long-term retention in an ecologically valid learning environment has not been demonstrated. We conducted two double-blind sham-controlled experiments examining the efficacy of auricular tVNS (taVNS: Experiment (1) and cervical tVNS (tcVNS: Experiment (2), on a 5 day second-language vocabulary acquisition protocol among highly selected career linguists at the US Department of Defense's premier language school. tcVNS produced accelerated recall performance during training (Day 2-4), benefits of which were maintained across a 24 h retention interval with no stimulation at the final test. Consistent with prior work, tcVNS also produced fatigue-mitigating and focus-promoting effects as measured by the Air Force Research Laboratory Mood Questionnaire. Based on the current and the previous findings supporting tVNS' efficacy on performance, training enhancement, and fatigue mitigation, we believe tcVNS to be an effective learning acceleration tool that can be utilized at language-teaching and other institutions focused on intensive training of cognitive skills.
