Objectives: We aimed to evaluate the effect of non-invasive NESA neuromodulation compared to posterior tibial nerve stimulation (PTNS) in patients with an overactive bladder (OAB), also given the same exercises and patient education, on quality of life, symptoms, discomfort and sleep quality. Method: Twenty-four women, aged 38–85 years with OAB, were included in this preliminary randomized controlled trial. Each patient attended ten sessions, twice a week. Patient pelvic floor function and urinary incontinence symptoms were collected throughout ICIQ-SF and B-SAQ questionnaires. Patient QoL and sleep quality were reported using SF-36 and PSQI, respectively. All outcomes were measured using three assessments: previous treatment (T1), immediately after treatment (T2) and two-month follow-up (T3). Results: Both groups showed significant improvements in pelvic floor function and urinary incontinence symptoms, as well as in sleep quality (p < 0.05). Although no significant differences between the groups were observed for any of the variables (p > 0.05), only the NESA group showed compelling improvements in quality of life (p < 0.05). Conclusions: The two treatments improved OAB symptoms, discomfort, and sleep quality in the short term yet only the non-invasive NESA group improved quality of life in women with OAB. These findings warrant further investigation in larger trials. Full article

In this review, we summarize current insights into the treatment of functional constipation (FC) in children. Constipation is a global issue in the pediatric population, with a prevalence of approximately 9.5%. Initial management involves a combination of non-pharmacological and pharmacological interventions. However, a significant number of children continue to experience therapy-resistant FC despite optimal non-pharmacological and pharmacological treatments. While studies on novel pharmacological options in children are limited, adult trials have shown promising results. New agents such as lubiprostone, prucalopride, linaclotide, and plecanatide have demonstrated improved outcomes compared to placebo or conventional therapies, particularly in increasing spontaneous bowel movements. Neurostimulation presents an additional treatment modality. Posterior tibial nerve stimulation appears to be a promising new option, offering high treatment satisfaction and a favorable safety profile with a low rate of severe adverse events. For children who do not respond to optimal conservative therapy, the impact on quality of life can be substantial. In such cases, surgical interventions may be considered, including intrasphincteric botulinum toxin injections, antegrade continence enema surgery, and, in severe cases, colonic resection or a diverting ostomy. The choice of surgical treatment remains a subject of ongoing debate. Therapy-resistant FC in children is a complex and impactful condition. An individualized, stepwise approach is essential, with surgical options such as colonic resection reserved as a last resort. Full article

Background/Objectives: Acute lateral ankle sprain (ALAS) affects balance, often assessed by changes in traditional center of pressure (COP) parameters. Spatiotemporal measures of COP and time-to-boundary (TTB) analysis may offer improved sensitivity in detecting postural deviations associated with ALAS. However, the neurophysiological mechanism underlying these changes remains unknown. This study aimed to explore the effects of ALAS on spinal reflex excitability in the fibularis longus (FL) during single-leg balance and TTB parameters following ALAS. Methods: Fourteen participants with and without ALAS were recruited within 14 days from the onset of the injury. We assessed FL spinal reflex excitability and postural control during a single-leg stance. The primary outcomes included the H/M ratio, H-latency, and TTB parameters. For H-reflex testing, the peripheral electrical stimulation was delivered at the sciatic nerve before bifurcating into the tibial and common fibular nerve while participants maintained a single-leg balance position with the involved side of the limb. The TTB parameters of the medial–lateral (ML) and anterior–posterior (AP) directions of the mean, SD, and minimum were assessed, which indicate postural correction and strategies. Results: Patients with ALAS had a significantly lower AP-TTB minimum compared with healthy uninjured controls, with a moderate effect size (p = 0.039; d = −0.83). However, there was no significant difference in the H/M ratio (ALAS: 0.29 ± 0.16 vs. CON: 0.24 ± 0.10; p = 0.258) and H-reflex latency (ALAS: 34.6 ± 1.92 vs. CON: 33.8 ± 1.75 ms; p = 0.277); Conclusions: These results indicate that reflex control at the spinal level may have a minimal role in response to balance deficits following ALAS.

Background: Primary dysmenorrhea is a leading cause of chronic cyclic pelvic pain, contributing to a reduced quality of life and sleep disturbances in women. The objective of this study was to assess the effectiveness of transcutaneous tibial nerve stimulation (TTNS) in improving the quality of life, sleep, and overall health perceptions of participants compared to a control group of women with dysmenorrhea over short-term, medium-term, and long-term periods. Methods: A single-blind, controlled clinical trial was conducted, with participants randomly assigned to an experimental group (receiving TTNS) or a control group (receiving sham TTNS). Both groups underwent 12, weekly 30 min sessions using the NeuroTrac™ PelviTone electrostimulation device. Outcomes related to quality of life, sleep deficiency, and overall improvement were evaluated at three time points: short-term (post-treatment), medium-term (1–3 months), and long-term (6 months). Results: Of the 61 participants initially randomized (31 in the experimental group and 30 in the control group), 55 completed the study and were included in the final analysis. A statistically significant improvement was observed in the experimental group in both physical and mental health components, as measured by the SF-36v2^® questionnaire, following 12 weeks of intervention, compared to the control group, persisting 6 months after the intervention. Additionally, statistically significant differences in overall improvement were noted between the two groups, as measured by the PGIC questionnaire at the end of treatment (p = 0.0103) and 6 months post-treatment (p = 0.0432). Conclusions: TTNS appears to be a safe and effective strategy for enhancing quality of life and overall health in women with PD, potentially reducing the reliance on pharmacological treatments or more invasive methods.

Background/Objectives: Multiple sclerosis (MS) frequently results in both urinary and sexual dysfunction, which significantly impairs quality of life. Conventional treatments for bladder dysfunction often prove insufficient, leading to the exploration of alternative therapies such as percutaneous tibial nerve stimulation (PTNS). This study aimed to assess the impact of PTNS on sexual function and bladder symptoms in female MS patients with neurogenic detrusor overactivity (NDO) and female sexual dysfunction (FSD). Methods: A total of 65 female MS patients with NDO were evaluated and underwent 12 weeks of standardized PTNS treatment. Sexual function was assessed using the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale-Revised (FSDS-R), while bladder symptoms were evaluated using the OAB-v8 questionnaire. Participants were grouped based on the presence of sexual dysfunction and distress and compared to a control group of 20 patients who declined PTNS. Results: Significant improvements were observed in FSFI scores across multiple domains (desire, arousal, lubrication, orgasm, satisfaction, and pain) in the treatment groups (p < 0.05). Additionally, 58.46% of patients showed positive responses to PTNS regarding overactive bladder symptoms (OAB-v8 score), while the control group showed no significant changes. Conclusions: PTNS appears to be an effective therapeutic option for improving sexual function and urinary symptoms in female MS patients with NDO and FSD, offering a promising non-invasive alternative for managing these conditions.

Primary dysmenorrhea is considered one of the main causes of pelvic pain during a woman’s childbearing years, resulting in poor quality of life. The objective was to evaluate the effectiveness of transcutaneous tibial nerve stimulation (TTNS) in painful symptomatology improvement and non-steroidal anti-inflammatory drug (NSAID) intake reduction in women with primary dysmenorrhea (PD) compared with a control group in the short, medium, and long terms. A single-blind, controlled clinical trial was developed. Participants were randomized to the experimental (TTNS) and control group (sham TTNS). Both groups received 12-weekly 30-min sessions with a NeuroTrac^TM PelviTone electrostimulation device. The intensity and severity of pain and non-steroidal anti-inflammatory drug (NSAID) intake were evaluated in the short-term (after treatment), medium-term (1–3 months), and long-term (6 months). A total of 61 participants were randomized, with a split of 31 (experimental group) and 30 (control group), but 55 participants completed the study and were analyzed. Statistically significant differences between both groups in the maximum pain intensity decrease (F = 4.88, p = 0.0043) measured with the visual analogue scale, as well as NSAID intake decrease (F = 4.68, p = 0.011) and days of their ingestion (F = 4.57, p = 0.012) occurred in the short term. Furthermore, significant decreases in the total number of NSAIDs ingested during the cycle (F = 3.82, p = 0.011) and the number of days on which patients ingested NSAIDs (F = 3.59, p = 0.015) in the medium–long term occurred. TTNS could be an effective and safe strategy to reduce pain caused by PD, which could reduce or complement the use of pharmacological techniques and other more invasive methods. Full article

Bladder dysfunction, particularly neurogenic detrusor overactivity (DO), poses a substantial challenge in multiple sclerosis (MS) patients, detrimentally impacting their quality of life (QoL). Conventional therapies often fall short, necessitating alternative approaches like posterior tibial nerve stimulation (PTNS) for effective management. This narrative review critically examines the application of PTNS in treating DO among MS patients, aiming to provide a comprehensive synthesis of its efficacy, underlying mechanisms, and clinical outcomes. By evaluating a spectrum of studies, including randomized controlled trials and long-term follow-up research, the review elucidates PTNS’s role in enhancing bladder control and ameliorating symptoms of urgency and incontinence, thereby improving patient well-being. Despite its potential, the review acknowledges the limited scope of existing research specific to MS-induced neurogenic DO and calls for further investigation to optimize PTNS protocols and understand its long-term benefits. Highlighting PTNS’s minimal invasiveness and favorable safety profile, the review advocates for its consideration as a viable third-line treatment option in MS-related bladder dysfunction management. Through this analysis, the review contributes to the broader narrative of seeking effective, patient-centered therapeutic strategies for MS-related complications, underscoring the importance of personalized care in improving patient outcomes.

Background: The reduction of muscular hypertonia is important in the treatment of various diseases or rehabilitation. This study aims to test the efficacy of a 5 Hz mechanical muscle stimulation (tapotement massage) in comparison to a 5 Hz repetitive peripheral magnetic stimulation (rPMS) on the neuromuscular reflex response. Methods: In a randomized control trial, 15 healthy volunteers were administered with either 5 Hz rPMS, tapotement massage, or rPMS sham stimulation. The posterior tibial nerve was stimulated with rPMS and sham stimulation. The Achilles tendon was exposed to a mechanically applied high-amplitude 5 Hz repetitive tendon tapotement massage (rTTM). The tendon reflex (TR) was measured for the spinal response of the soleus muscle. Results: After rPMS, there was a reduction of the TR response (−9.8%, p ≤ 0.034) with no significant changes after sham stimulation. Likewise, TR decreased significantly (−17.4%, p ≤ 0.002) after Achilles tendon tapotement intervention. Conclusions: These findings support the hypothesis that both afferent 5 Hz sensory stimulations contributed to a modulation within the spinal and/or supraspinal circuits, which resulted in a reduction of the spinal reflex excitability. The effects could be beneficial for patients with muscle hypertonia and could improve the functional results of rehabilitation programs. Full article

Background: Functional constipation can lead to painful defecations, fecal incontinence, and abdominal pain, significantly affecting a child’s quality of life. Treatment options include non-pharmacological and pharmacological approaches, but some cases are intractable and require alternative interventions like neuromodulation. A subtype of neuromodulation, called Transcutaneous Posterior Tibial Nerve Stimulation (TPTNS), comprises electrical stimulation at the ankle level, by means of electrodes fixed to the skin. TPTNS is a minimally invasive, easy-to-apply technique that can potentially improve constipation symptoms in the pediatric population by stimulating the sacral nerves. Aim: To evaluate the clinical results and applicability of TPTNS as an adjuvant treatment for children and adolescents with functional constipation. Methods: Between April 2019 and October 2021, 36 patients diagnosed with functional constipation according to the Rome IV Criteria were invited to participate in the study. The study followed a single-center, uncontrolled, prospective cohort design. Patients received TPTNS for 4 or 8 weeks, with assessments conducted immediately after the periods of TPTNS and 4 weeks after the end of the intervention period. The data normality distribution was determined by the Shapiro–Wilk test. The Wilcoxon test and Student’s t-test for paired samples were used to compare quantitative variables, and the McNemar test was used to compare categorical variables. Results: Of the 36 enrolled patients, 28 children and adolescents with intractable function constipation completed the study, receiving TPTNS for 4 weeks. Sixteen patients (57.1%) extended the intervention period for 4 extra weeks, receiving 8 weeks of intervention. TPTNS led to significant improvements in stool consistency, frequency of defecation, and bowel function scores, with a reduction in abdominal pain. Quality of life across physical and psychosocial domains showed substantial enhancements. The quality of life-related to bowel habits also improved significantly, particularly in lifestyle, behavior, and embarrassment domains. The positive effects of this intervention are seen relatively early, detected after 4 weeks of intervention, and even 4 weeks after the end of the intervention. TPTNS was well-tolerated, with an adherence rate of approximately 78%, and no adverse effects were reported. Conclusions: TPTNS is an adjuvant treatment for intractable functional constipation, improving bowel function and quality of life. The effects of TPTNS were observed relatively early and sustained even after treatment cessation. Full article

This study aimed to investigate the effectiveness of posterior tibial nerve stimulation (PTNS) in reducing pain, improving quality of life, and decreasing disease severity in patients with fibromyalgia. This prospective, single-blind, randomized controlled trial included female patients newly diagnosed with fibromyalgia who had started duloxetine treatment (30 mg/day). The patients in the study group received six sessions of posterior tibial nerve stimulation, twice weekly, 3–4 days apart, in addition to duloxetine; the controls received duloxetine only. The patients were evaluated three times (at baseline, 1st month, and 3rd month). Pain was evaluated using a numeric rating scale, the short-form McGill Pain Questionnaire, and quality of life with a 36-item short-form health survey (SF-36). Patient functional status and disease severity were evaluated using the fibromyalgia impact questionnaire (FIQ). A total of 64 patients met the inclusion criteria: 22 were ultimately included in the study group and 30 in the control group. Statistical improvements in pain and FIQ scores were observed after treatment in both groups. The SF-36 scores indicated improved vitality only in the 1st month in both groups, with no significant changes in the other quality-of-life subscales in either group. There was no statistical difference between the two groups in terms of changes in pain, FIQ, and SF-36 scores compared with baseline at the 1st month and 3rd month. The addition of PTNS to pharmacological treatment did not contribute to the reduction in pain or improvement in quality of life in fibromyalgia either in the 1st or 3rd month.

Primary dysmenorrhea (PD) is a painful menstruation that can persist for the duration of a woman’s fertile life. Non-steroidal anti-inflammatory drugs, hormonal therapy, physiotherapy techniques, etc., are the main treatments. The main objective of this study is to evaluate the effectiveness of transcutaneous posterior tibial nerve stimulation (TTNS) in PD patients. The study will consist of a single-blind randomized clinical trial, parallel-assigned with two arms. Women with PD (18–43 years) with regular menstrual cycles and at least 4 points in VAS will be randomly divided into experimental (TTNS) and placebo (simulated stimulation) groups during 12 treatment sessions (1 session/week) and several follow-ups: monthly during treatment and 1, 3 and 6 months after. Maximum and mean pain intensity, pain duration, pain severity, number of anti-inflammatory drugs, quality of life, sleep quality, overall improvement, treatment satisfaction and secondary effects will be measured once a month every 6 months and at 3 and 6 months. The Student’s t-test for independent samples or the Mann–Whitney U test will be used. The literature shows effective physiotherapeutic techniques for PD in the short term, which do not act on causes and have limitations. The TTNS technique can be used in transcutaneous and percutaneous modalities, with similar effectiveness, but the transcutaneous causes less discomfort. TTNS modulates pain, and long-term benefits could be achieved at low cost and without patient discomfort. Full article

Fecal incontinence is a condition that carries high social stigmatization and a determining factor in the quality of life of the person who suffers from it. Its etiology is multifactorial and treatment includes surgical and conservative measures, including stimulation of the posterior tibial nerve. The aim of this review is to determine whether posterior tibial nerve stimulation (PTNS) is more effective than other treatments in reducing episodes of fecal incontinence in adults. A systematic review of randomized clinical trials that analyzed different approaches and comparisons with other treatments in adults without neurological or metabolic diseases was carried out, analyzing, fundamentally, the reduction of episodes of fecal incontinence. In general, a reduction in fecal incontinence episodes is observed in the experimental groups compared with the control groups, although these differences are not significant in most studies. The results regarding the effectiveness of PTNS in reducing episodes of fecal incontinence compared to other treatments are not entirely conclusive, although benefits are observed regarding the stimulation of sacral roots. More well-designed studies with a long-term follow-up of the results are needed so that the recommendation of this treatment can be generalized. Full article

Background: Posterior tibial nerve stimulation (PTNS) is one of the treatment modalities for children with therapy-refractory lower urinary tract dysfunction (LUTD). This study used a mixed-methods analysis to gain insight into the experiences of children treated with PTNS and their parents, the effect of treatment on quality of life (QOL) and the effect of PTNS on urinary symptoms. Methods: Quantitative outcomes were assessed through a single-centre retrospective chart analysis of all children treated with PTNS in a group setting between 2016–2021. Voiding parameters and QOL scores before and after treatment were compared. Qualitative outcomes were assessed by an explorative study involving semi-structured interviews transcribed verbatim and inductively analysed using the constant-comparative method. Results: The data of 101 children treated with PTNS were analysed. Overall improvement of LUTD was seen in 42% and complete resolution in 10%. Average and maximum voided volumes significantly increased. QOL improved in both parents and children independent of the actual effect on urinary symptoms. Interviews revealed PTNS to be well-tolerated. Facilitating PTNS in a group setting led to feelings of recognition in both children and parents. Conclusions: PTNS is a good treatment in children with therapy-refractory LUTD and provides valuable opportunities for peer support if given in a group setting. Full article

The management of patients with fecal incontinence and an external anal sphincter (EAS) defect remains controversial. A retrospective series of overlapping anal sphincteroplasties performed between 1985–2013 from a single center, supplemented by selective puborectalis plication and internal anal sphincter repair is presented. Patients were clinically followed along with anorectal manometry, continence scoring (Cleveland Clinic Incontinence Score—CCS) and patient satisfaction scales. Patients with a suboptimal outcome were managed with combinations of biofeedback therapy (BFT), peripheral tibial nerve stimulation (PTNS), sacral nerve stimulation (SNS) or repeat sphincteroplasty. There were 120 anterior sphincter repairs with 90 (75%) levatorplasties and 84 (70%) IAS repairs. Over a median follow-up of 120 months (IQR 60–173.7 months) there were significant improvements in the recorded CCIS values (90.8% with a preoperative CCIS > 15 vs. 2.5% postoperatively; p < 0.001). There were 42 patients who required ancillary treatment with four repeat sphincteroplasties, 35 patients undergoing biofeedback therapy, 10 patients treated with PTNS and three managed with SNS implants with an ultimate good functional outcome in 92.9% of cases. No difference was noted in ultimate functional outcome between those treated with sphincteroplasty alone compared with those who needed ancillary treatments (97.1% vs. 85.7%, respectively). Overall, 93.3% considered the outcome as either good or excellent. Long-term functional outcomes of an overlapping sphincteroplasty are good. If the initial outcome is suboptimal, response to ancillary treatments remains good and patients are not compromised by a first-up uncomplicated sphincter repair. Full article

Urinary incontinence is considered a health problem that both elderly and young people can suffer, most often elderly women. This problem can lead to difficulties in establishing social relationships and dependence, negatively affecting the quality of life of the people who suffer from it. To evaluate and analyze the studies that demonstrate the efficacy of interventions based on the neuromodulation of the posterior tibial nerve as a treatment for the control of urinary incontinence. The search period for articles focused on those published between March 2011 to March 2021, in five databases (Pubmed, Cochrane Library, Scielo, Google Academic and WOS) based on the clinical question, using the keywords derived from the DeCS and MeSH thesauri, combined with the Boolean operators “AND”, “NOT” and “OR”. The search was limited to publications from the last 10 years, in English and Spanish. After applying the selection criteria and evaluating the quality of the methodology, 5.28% (n = 27) of the 511 results were included with filters: 9 systematic reviews, 10 cohorts and 8 randomized controlled trials. After comparing the different articles, it was found that percutaneous stimulation of the tibial nerve is a suitable technique for treating overactive bladder. It is a promising technique in case of pelvic floor dysfunctions and effective for the control of urinary incontinence. Full article
