Knowledge, Attitudes, and Practices on New Treatment Modalities for Temporomandibular Dysfunctions and Orofacial Pain / Conocimientos, Actitudes y Prácticas sobre Nuevas Nodalidades de Tratamiento de las Disfunciones Tempomanibulares y el Dolor Orofacial

The present study proposed to describe, through a literature review, the use of new therapeutic management which allows for offering a better quality of life to individuals affected by these pathologies. A bibliographic search was conducted in the main health databases PUBMED (www.pubmed.gov) and Scholar Google (www.scholar.google.com.br), in which studies published from 1987 to 2023 were collected. In the first stage, the list of retrieved articles was examined by reading the titles and abstracts. In the second stage, the studies were selected by reading the full contents. Two authors (JDMM and DAQ) performed stages 1 and 2. Experimental, clinical, case-control, randomized controlled, and laboratory cohort studies, case reports, systematic reviews, and literature reviews, which were developed in living individuals, were included. Therefore, articles that did not deal with the subject in question, letters to the editor, opinion articles, duplicated literature in databases, and literature that did not address the variables under study, we re excluded. Contemporary dentistry uses alternative treatments capable of improving the patient's condition since a cure is not always possible. Therefore, the possibility of improving the quality of life becomes an important point to be reached. Evidence-based healthcare has made great advances in recent decades, especially in the areas of orofacial pain, TMD, and occlusion, especially related to orthodontic, prosthetic, and restorative care.

En el presente estudio se propuso describir, a través de una revisión bibliográfica, el uso de nuevos manejos terapéuticos que permitan brindar una mejor calidad de vida a los individuos afectados por estas patologías. Se realizó una búsqueda bibliográfica en las principales bases de datos de salud PUBMED (www.pubmed.gov) y Scholar Google (www.scholar.google.com.br), en las que se recopilaron estudios publicados entre 1987 y 2023. En la primera etapa, se examinó la lista de artículos recuperados mediante la lectura de los títulos y resúmenes. En la segunda etapa, los estudios fueron seleccionados mediante la lectura del contenido completo. Dos autores (JDMM y DAQ) realizaron las etapas 1 y 2. Se incluyeron estudios de cohortes experimentales, clínicos, de casos y controles, controlados aleatorios y de laboratorio, informes de casos, revisiones sistemáticas y revisiones de la literatura, que se desarrollaron en individuos vivos. Por lo tanto, se excluyeron artículos que no trataran el tema en cuestión, cartas al editor, artículos de opinión, literatura duplicada en bases de datos y literatura que no abordara las variables en estudio. La odontología contemporánea utiliza tratamientos alternativos capaces de mejorar el estado del paciente, ya que no siempre es posible la curación. Por lo tanto, la posibilidad de mejorar la calidad de vida se convierte en un objetivo importante. La atención médica basada en la evidencia ha logrado grandes avances en las últimas décadas, especialmente en las áreas de dolor orofacial, TMD y oclusión, especialmente en relación con la atención de ortodoncia, prótesis y restauración.

Effect of transcutaneous auricular vagus nerve stimulation on functional connectivity in the related brain regions of patients with depression based on the resting-state fMRI / 中国针灸

OBJECTIVE@#To explore the brain effect mechanism and the correlation between brain functional imaging and cognitive function in treatment of depressive disorder (DD) with transcutaneous auricular vagus nerve stimulation (taVNS) based on the resting-state functional magenetic reasonance imaging (rs-fMRI).@*METHODS@#Thirty-two DD patients were included in a depression group and 32 subjects of healthy condition were enrolled in a normal group. In the depression group, the taVNS was applied to bilateral Xin (CO15) and Shen (CO10), at disperse-dense wave, 4 Hz/20 Hz in frequency and current intensity ≤20 mA depending on patient's tolerance, 30 min each time, twice daily. The duration of treatment consisted of 8 weeks. The patients of two groups were undertaken rs-fMRI scanning. The scores of Hamilton depression scale (HAMD), Hamilton anxiety scale (HAMA) and Wisconsin card sorting test (WCST) were observed in the normal group at baseline and the depression group before and after treatment separately. The differential brain regions were observed before and after treatment in the two groups and the value of degree centrality (DC) of fMRI was obtained. Their correlation was analyzed in terms of HAMD, HAMA and WCST scores.@*RESULTS@#The scores of HAMD and HAMA in the depression group were all higher than those in the normal group (P<0.05). After treatment, the scores of HAMD and HAMA were lower than those before treatment in the depression group; the scores of total responses, response errors and perseverative errors of WCST were all lower than those before treatment (P<0.05). The brain regions with significant differences included the left inferior temporal gyrus, the left cerebellar peduncles region 1, the left insula, the right putamen, the bilateral supplementary motor area and the right middle frontal gyrus. After treatment, the value of DC in left supplementary motor area was negatively correlated to HAMD and HAMA scores respectively (r=-0.324, P=0.012; r=-0.310, P=0.015); the value of DC in left cerebellar peduncles region 1 was negatively correlated to the total responses of WCST (r=-0.322, P=0.013), and the left insula was positively correlated to the total responses of WCST (r=0.271, P=0.036).@*CONCLUSION@#The taVNS can modulate the intensity of the functional activities of some brain regions so as to relieve depressive symptoms and improve cognitive function.

Acute whole-body electromyostimulation associated with dynamic exercises did not alter cardiac autonomic modulation and oxygen uptake in obese and eutrophic men

Abstract Aim: To contrast the acute effects of whole-body electromyostimulation (WB-EMS) with sham associated with dynamic exercises on cardiovascular, ventilatory, metabolic, and autonomic responses in men with obesity and controls. Methods: A randomized cross-over and double-blind trial with nine eutrophic (23.6 years; 23 ± 1.4 kg/m2) and ten men with obesity (26 ± 4 years; 38 ± 7 kg/m2), who were randomized to receive WB-EMS-Sham or Sham-WB-EMS with 30 min of rest between protocols. WB-EMS protocol (Miha Bodytec®) was applied at the motor level, frequency = 85 Hz, pulse duration = 350 μs, cycle on = 6′; cycle off = 4′. Sham group performed the same exercises with the electric current turned off. Throughout both protocols, subjects executed two dynamic exercises of 5 minutes each (step-up and step down associated with shoulder flexion, and lunge exercise associated with elbow flexion) in the same order. R-R intervals and breath-by-breath respiratory gases analysis were collected during the protocols. Heart rate variability (HRV) indexes were obtained using linear and nonlinear analysis. The level of statistical significance was set at p < 0.05. Results: Regarding both exercises, participants with obesity presented reduced oxygen uptake, higher ventilation, respiratory rate, blood pressure, and Borg scores (p < 0.05) when contrasted with controls, as expected. However, no significant differences were found for HRV indexes between groups (p > 0.05). In addition, WB-EMS did not increase oxygen uptake or altered autonomic modulation when contrasted with sham in both groups (p < 0.05). Conclusion: Obesity has a negative impact on symptoms and functional capacity. However, WB-EMS did not acutely enhance oxygen uptake or HRV during exercise in a population with obesity.

Conclusions: The ultrasonotherapy was more effective in patients with temporomandibular joint disorders.

Transcutaneous tibial nerve stimulation versus parasacral stimulation in the treatment of overactive bladder in elderly people: a triple-blinded randomized controlled trial

OBJECTIVES: To evaluate the effect of transcutaneous tibial nerve stimulation (TTNS) and transcutaneous parasacral stimulation on the treatment of overactive bladder (OAB) in elderly people and to compare the final results between groups. METHODS: Fifty female volunteers, mean age 68.62 (±5.9) years, were randomly allocated into two groups: those receiving TTNS (G1, N=25) and those receiving transcutaneous parasacral stimulation (G2, N=25). The primary outcome was the International Consultation on Incontinence Questionnaire (ICIQ-OAB) score, and secondary outcomes were the International Consultation on Incontinence Questionnaire - short form (ICIQ-SF) score and 3-day bladder diary measurements. Volunteers were assessed before and after the treatment. Clinical Trials (ReBeC): RBR-9Q7J7Y. RESULTS: Both groups' symptoms improved as measured by the ICIQ-OAB (G1 = <0.001; G2 = <0.001) and ICIQ-SF (G1 = <0.001; G2 = <0.001). In the 3-day bladder diary assessments after treatment, G1 showed a reduced number of nocturia (p<0.001), urgency (p<0.001) and urge urinary incontinence episodes (p<0.001), whereas G2 showed only a reduced number of nocturia episodes (p<0.001). No difference between groups was found. CONCLUSION: Both of the proposed treatments were effective in the improvement of OAB symptoms, but TTNS showed a reduction in a greater number of symptoms as measured by the 3-day bladder diary. No differences were found between groups.

Spinal Cord Electrical Stimulation for Refractory Angina Treatment

Cardiovascular disease (CVD) is the main cause of death worldwide, including in Brazil. Angina pectoris is a challenging disease because its clinical manifestation is not always related to the degree of obstruction. Visceral pain fromany source can be totally disabling. It influences all aspects of the life of a patient and it can be one of the main causes of absence from work and of family disruption. Spinal cord electrical stimulation (SCES) has been traditionally applied for the treatment of neuropathic pain, with good to excellent results. Visceral pain syndrome can be as debilitating and disabling as somatic or neuropathic pain; however, there seems to be a lack of consensus on the appropriate treatment and strategies for these disorders. Themajor difference of SCES for visceral pain, compared to postlaminectomy syndrome or to regional complex syndrome, is the number of stimulated dermatomes. In most viscera, the somatotopic arrangement has two to four medullar levels, sometimes requiring laterality. After reviewing the literature, we have concluded that SCES is now a viable, low-risk option with satisfactory results for the treatment of neuropathic and visceral pain; therefore, it can be used in refractory angina after the failure of standard therapy. However, further studies are required to increase the application and efficacy of this procedure in the clinical practice.

RESUMO Lesões de nervos periféricos levam a perda funcional elevada no tecido muscular. Assim, muitas pesquisas têm investigado técnicas cirúrgicas, como neurorrafias, e recursos terapêuticos, como eletroestimulação, para melhorar a funcionalidade de um músculo reinervado após lesão periférica. Este estudo tem como objetivo investigar os efeitos da eletroestimulação com corrente russa (2.500Hz, 4ms, 10 seg. de contração por 20 seg. de relaxamento, modulação de 10Hz e 100 Hz) na recuperação funcional após secção e neurorrafia término-lateral do coto distal do nervo fibular comum à face lateral do nervo tibial em ratos. Foram utilizados 25 ratos Wistar, machos, com 80 dias de vida, fornecidos pelo Biotério Central da Universidade Sagrado Coração (Bauru, SP, Brasil). Os animais foram divididos aleatoriamente em cinco grupos: grupo-controle Inicial (GCI), grupo-controle final (GCF), grupo experimental não tratado (GENT), grupo neurorrafia término-lateral com estimulação russa (GNTLER) e grupo-controle desnervado (GCD). A corrente russa foi iniciada cinco dias após neurorrafia e aplicada no músculo tibial cranial do GNTLER, 3 vezes por semana, totalizando 36 sessões. A estimulação elétrica foi eficaz para aumentar a amplitude e diminuir a latência do músculo reinervado, além de aumentar a força muscular em comparação ao GCD. Diante disso, conclui-se que a eletroestimulação de média frequência (corrente russa) foi eficiente na recuperação funcional do músculo tibial cranial após neurorrafia término-lateral do nervo fibular comum.

RESUMEN Las lesiones de los nervios periféricos ocasionan una elevada pérdida funcional en el tejido muscular. De esta manera, en muchos estudios se han investigado técnicas quirúrgicas, como neurorrafias, y recursos terapéuticos, como la electroestimulación, para mejorar la funcionalidad del músculo reinervado tras una lesión periférica. El presente estudio tiene como objetivo investigar los efectos de la electroestimulación con corrente rusa (2.500Hz, 4ms, 10 seg. de contracción por 20 seg. de relajación, modulación de 10Hz y 100Hz) en la recuperación funcional tras la sección y neurorrafia término-lateral del muñón distal del nervio fibular común en la parte lateral del nervio tibial en ratas. Se utilizaron 25 ratas Wistar, machos, con 80 días de vida, proporcionadas por el Biotério Central de la Universidade do Sagrado Coração (Bauru, SP, Brasil). Se dividieron aleatoriamente los animales en cinco grupos: grupo de control inicial (GCI), grupo de control final (GCF), grupo experimental no tratado (GENT), grupo de neurorrafia término-lateral con estimulación rusa (GNTLER) y grupo de control denervado (GCD). La corriente rusa se inició cinco días tras la neurorrafia, siendo que la aplicó al músculo tibial craneal del GNTLER 3 veces a la semana, con un total de 36 sesiones. La estimulación eléctrica se mostró efectiva para aumentar la amplitud y disminuir la latencia del músculo reinervado, además de aumentar la fuerza muscular en comparación con el GCD. Por lo tanto, se concluye que la estimulación eléctrica de frecuencia media (corriente rusa) fue eficaz en la recuperación funcional del músculo tibial craneal tras la neurorrafia término-lateral del nervio fibular común.

ABSTRACT Peripheral nerve injury leads to a high functional loss of muscle tissue. Thus, many studies have investigated surgical techniques, such as neurorraphies, and therapeutic resources, such as electrical stimulation, to improve the functionality of reinnervated muscle after peripheral injury. This study aims to investigate the effects of electrical stimulation with Russian Current (2,500Hz, 4ms, 10:20 sec contraction/relaxation, modulated at 10Hz and 100Hz) in the functional recovery after section and end-to-side neurorrhaphy of the peroneal nerve distal stump common to the lateral face of the tibial nerve in rats. In this study, 25 male Wistar rats with 80 days of life were used, provided by the Universidade Sagrado Coração (USC), Bauru, SP, Brazil. The animals were randomly divided into five groups: Initial Control Group (ICG), Final Control Group (FCG), Untreated Experimental Group (UEG), End-to-Side Neurorrhaphy with Russian Stimulation Group (ENRSG), and Denervated Control Group (DCG). The Russian Current was started 5 days after neurorrhaphy and applied to the cranial tibial muscle of the ENRSG, 3 times a week, totaling 36 sessions. We observed that the electrical stimulation with Russian Current (ENRSG) was effective to increase amplitude (mV) and to decrease the latency (ms) of the reinnervated muscle, besides increasing the muscle strength when compared with the denervated control group. Therefore, we concluded that the average frequency electrical stimulation (Russian current) was efficient in the functional recovery of the cranial tibial muscle after the end-lateral neurorrhaphy of the common fibular nerve.

Effectiveness and durability of solifenacin versus percutaneous tibial nerve stimulation versus their combination for the treatment of women with overactive bladder syndrome: a randomized controlled study with a follow-up of ten months

ABSTRACT Purpose To assess effectiveness and durability of Solifenacin (SS) versus tibial nerve stimulation (PTNS) versus combination therapy (PTNS + SS) in women with overactive bladder syndrome (OAB). Materials and Methods 105 women with OAB were divided randomly into three groups of 35 patients each. In group A women received SS, in group B women underwent PTNS, in group C women underwent combination of PTNS + SS. Improvements in OAB symptoms were assessed with OABSS questionnaire; patients' quality of life was assessed with OAB-q SF questionnaire. Evaluation of effectiveness of treatments was performed with PGI-I questionnaire. OABSS and PGI-I were also assessed monthly for ten months. Results All treatments were effective on symptoms. PTNS showed a greater effectiveness than SS, but PTNS + SS was more effective than SS and PTNS. Furthermore, PTNS + SS showed a greater duration of effectiveness than PTNS and SS. Conclusions Combination of PTNS with SS showed more effectiveness and more durability than PTNS and SS alone.

Short-term transcutaneous electrical nerve stimulation reduces pain and improves the masticatory muscle activity in temporomandibular disorder patients: a randomized controlled trial

Abstract Studies to assess the effects of therapies on pain and masticatory muscle function are scarce. Objective To investigate the short-term effect of transcutaneous electrical nerve stimulation (TENS) by examining pain intensity, pressure pain threshold (PPT) and electromyography (EMG) activity in patients with temporomandibular disorder (TMD). Material and Methods Forty patients with myofascial TMD were enrolled in this randomized placebo-controlled trial and were divided into two groups: active (n=20) and placebo (n=20) TENS. Outcome variables assessed at baseline (T0), immediately after (T2) and 48 hours after treatment (T1) were: pain intensity with the aid of a visual analogue scale (VAS); PPT of masticatory and cervical structures; EMG activity during mandibular rest position (MR), maximal voluntary contraction (MVC) and habitual chewing (HC). Two-way ANOVA for repeated measures was applied to the data and the significance level was set at 5%. Results There was a decrease in the VAS values at T1 and T2 when compared with T0 values in the active TENS group (p<0.050). The PPT between-group differences were significant at T1 assessment of the anterior temporalis and sternocleidomastoid (SCM) and T2 for the masseter and the SCM (p<0.050). A significant EMG activity reduction of the masseter and anterior temporalis was presented in the active TENS during MR at T1 assessment when compared with T0 (p<0.050). The EMG activity of the anterior temporalis was significantly higher in the active TENS during MVC at T1 and T2 when compared with placebo (p<0.050). The EMG activity of the masseter and anterior temporalis muscle was significantly higher in the active TENS during HC at T1 when compared with placebo (p<0.050). Conclusions The short-term therapeutic effects of TENS are superior to those of the placebo, because of reported facial pain, deep pain sensitivity and masticatory muscle EMG activity improvement.

Percutaneous tibial nerve stimulation versus electrical stimulation with pelvic floor muscle training for overactive bladder syndrome in women: results of a randomized controlled study

ABSTRACT Introduction This study compared percutaneous tibial nerve stimulation (PTNS) versus electrical stimulation with pelvic floor muscle training (ES + PFMT) in women with overactive bladder syndrome (OAB). Materials and Methods 60 women with OAB were enrolled. Patients were randomized into two groups. In group A, women underwent ES with PFMT, in group B women underwent PTNS. Results A statistically significant reduction in the number of daily micturitions, episodes of nocturia and urge incontinence was found in the two groups but the difference was more substantial in women treated with PTNS; voided volume increased in both groups. Quality of life improved in both groups, whereas patient perception of urgency improved only in women treated with PTNS. Global impression of improvement revealed a greater satisfaction in patients treated with PTNS. Conclusion This study demonstrates the effectiveness of PTNS and ES with PFMT in women with OAB, but greater improvements were found with PTNS.

La artritis reumatoidea juvenil y su influencia en la alteración de desarrollo de la mandíbula / Juvenile rheumatoid arthritis and its influence on the alteration of jaw development

La artritis reumatoidea juvenil (ARJ) es una enfermedad inflamatoria autoinmune que se presenta en niños menores de 16 años. Es de curso crónico, etiología desconocida, y afecta sobre todo las articulaciones, como la temporomandibular (ATM). El daño de la ATM puede ocasionar: alteraciones en el crecimiento facial (micrognatia), maloclusión clase II, mordida abierta anterior, desviaciones laterales, erosiones óseas, destrucción del cón-dilo, oclusión disfuncional y alteración de la estética facial, entre otras consecuencias. La posición oclusal neurofisiológica lograda por medio de elementos electrónicos, como el Transcutaneus Electrical Neural Stimulation (TENS), y mantenida por el Dispositivo Intaroral (DIO) podría posibilitar la remodelación de la cabeza del cóndilo, en pacientes en crecimiento, en los que la enfermedad se halla controlada, regulando así también la sintomatología dolorosa...

Overactive bladder - 18 years - Part II

ABSTRACT Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics – pillars of the overactive bladder pharmacotherapy – started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning – as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder – 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.

Introduction: Cerebral Palsy (CP) may be associated with urinary incontinence (UI), which may be due to neurological disorders. Objective: To evaluate the effectiveness of transcutaneous electrical stimulation (TENS) of the posterior tibial nerve in women's quality of life with UI and CP. Method: Case report with two women (28 and 36 years). We evaluated the type of urinary dysfunction and King's Health Questionnaire (KHQ). We held 20 sessions of electrostimulation with a frequency of 60 Hz, pulse width 200µs, frequency of 01 Hz current. The intensity was set according to each patient. Results: Both reduced the number of bathroom visits and exchanges of liners. In KHQ, the patient 1 improved in domains: impact of incontinence, limitation of tasks, physical / social limitation and security measures. Patient 2, in the domains of tasks limitations, personal relationships and sleep / energy. Conclusion: TENS improved the quality of life of these women.

Efetividade da estimulação elétrica nervosa transcutânea (TENS) na terapia vocal de mulheres disfônicas: ensaio clínico, controlado, randomizado e cego / Effectiveness of transcutaneous electrical nerve stimulation (TENS) in voice therapy of dysphonic women: control, randomized and double blind clinical trial

Introdução: Para o tratamento das disfonias comportamentais associadas à tensão muscular são recomendadas técnicas de relaxamento cervical e laríngeo, concomitantemente à estimulação da onda de mucosa das pregas vocais, bem como adequação do fechamento glótico e suavização da emissão. Nesse sentido, o recurso da Estimulação Elétrica Nervosa Transcutânea (TENS), corrente elétrica aplicada por meio de eletrodos de superfície, tem sido utilizada no tratamento vocal de mulheres com nódulos vocais. Esta prática tem demonstrado bons resultados na qualidade vocal e na redução da dor muscular, porém, verifica-se escassez de comprovação científica dos seus efeitos somados à terapia vocal. Objetivo: verificar a efetividade da TENS de baixa frequência associada à terapia vocal no tratamento de voz em mulheres disfônicas. Método: Este estudo foi aprovado pelo Comitê de Ética em Pesquisa em Seres Humanos, número 556.273. Participaram 27 mulheres com nódulos vocais, de 18 a 45 anos de idade (média de 33 anos de idade), divididas, de forma randomizada, em: Grupo Experimental (GE) – 13 mulheres que receberam 12 sessões de aplicação de TENS (pulso: 200 μs, frequência: 10 Hz, no limiar motor), com eletrodos posicionados no músculo trapézio - fibras descendentes e na região submandibular, bilateralmente, por 20 minutos, associada a 30 minutos de terapia vocal; e Grupo Controle (GC) – 14 mulheres que receberam 12 sessões de aplicação de TENS placebo (mesmas condições do GE, incluindo posicionamento dos eletrodos, porém sem receber o estímulo em forma de corrente elétrica) por 20 minutos, associada a 30 minutos de terapia vocal. Todas foram submetidas à avaliação da qualidade vocal por meio das análises perceptivo-auditiva e acústica da voz; da laringe por meio de análise perceptivo-visual; autopercepção sobre a voz, qualidade de vida por meio do protocolo de Qualidade de Vida em Voz...

Introduction: For the treatment of the behavior dysphonia associated muscle tension are recommended techniques of cervical and laryngeal relaxation, concurrently with stimulation of the mucosa wave of the vocal folds, such as adequacy of glottal closure and smoothing the emission. Thereby, the use of Transcutaneous Electrical Nerve Stimulation (TENS), electrical current applied through surface electrodes, have been used in the vocal treatment of women with vocal nodules. This practice has shown good results in vocal quality and in reducing muscle pain, however, there are few scientific evidence about their effects added to voice therapy. Proposal: to verify the effectiveness of low frequency TENS associated with voice therapy on vocal quality and laryngeal dysphonic women. Methods: This study was approved by the Research Ethics Committee, number 556.273. Twenty seven women with vocal nodules participated, 18-45 years of age (mean 33 years), divided, randomly into: experimental group (EG) - 13 women who received 12 sessions of application TENS (pulse: 200 μs, frequency 10 Hz, motor threshold), with electrodes placed on the trapezius muscle – descending fibers and submandibular area, bilaterally, for 20 minutes, associated with 30 minutes of vocal therapy; and Control Group (CG) - 14 women who received 12 sessions of application TENS placebo (same conditions as EG, including the placed of the electrodes, but without receiving the stimulus in the form of electrical current) for 20 minutes, associated with 30 minutes of vocal therapy. All were submitted to vocal quality through auditory perceptual and acoustic voice analyzes; ENT evaluation through visual perceptual analysis; vocal self-perception; voice-related quality of life through the Voice-Related Quality of Life Protocol (V-RQOL); complaints and vocal/laryngeal and musculoskeletal pain symptoms, before, immediately after treatment and one month after.

Can transcutaneous electrical nerve stimulation improve achilles tendon healing in rats?

BACKGROUND: Tendon injury is one of the most frequent injuries in sports activities. TENS is a physical agent used in the treatment of pain but its influence on the tendon's healing process is unclear. OBJECTIVE: To evaluate the influence of TENS on the healing of partial rupture of the Achilles tendon in rats. METHOD: Sixty Wistar rats were submitted to a partial rupture of the Achilles tendon by direct trauma and randomized into six groups (TENS or Sham stimulation) and the time of evaluation (7, 14, and 21 days post-injury). Burst TENS was applied for 30 minutes, 6 days, 100 Hz frequency, 2 Hz burst frequency, 200 µs pulse duration, and 300 ms pulse train duration. Microscopic analyses were performed to quantify the blood vessels and mast cells, birefringence to quantify collagen fiber alignment, and immunohistochemistry to quantify types I and III collagen fibers. RESULTS: A significant interaction was observed for collagen type I (p=0.020) where the TENS group presented lower percentage in 14 days after the lesion (p=0.33). The main group effect showed that the TENS group presented worse collagen fiber alignment (p=0.001) and lower percentage of collagen III (p=0.001) and the main time effect (p=0.001) showed decreased percentage of collagen III at 7 days (p=0.001) and 14 days (p=0.001) after lesion when compared to 21 days. CONCLUSIONS: Burst TENS inhibited collagen I and III production and impaired its alignment during healing of partial rupture of the Achilles tendon in rats.
