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.

The patients in the control group received enhance recovery after surgery (ERAS) standardized perioperative management. On the basis of the treatment in the control group, the TEAS group was treated with TEAS at Liangmen (ST 21) and Daheng (SP 15); the EA group was treated with EA at Neiguan (PC 6), Hegu (LI 4), Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39); the combination group was treated with TEAS combined with EA, with continuous wave, 2-5 Hz in frequency, and the intensity was tolerable to the patients, 30 min each time, once a day, from the first day after surgery, until the anus resumed spontaneous defecation and the oral intake of solid food was tolerated. The gastrointestinal-2 (GI-2) time, first exhaust time, first defecation time, first tolerance of oral intake of solid food time, time of first get out of bed and hospital stay were observed in all the groups; the pain visual analogue scale (VAS) score and incidence rates of nausea and vomiting 1, 2, 3 days after surgery were compared in all the groups; after treatment, the acceptability of each treatment was evaluated by patients in each group.@*RESULTS@#Compared with the control group, the GI-2 time, first exhaust time, first defecation time, first tolerance of oral intake of solid food time were shortened (P<0.05), the VAS scores 2, 3 days after surgery were decreased (P<0.05) in the combination group, the TEAS group and the EA group; those in the combination group were shorter and lower than the TEAS group and the EA group (P<0.05). Compared with the control group, the time of hospital stay in the combination group, the TEAS group and the EA group were shortened (P<0.05), and that in the combination group was shorter than the TEAS group (P<0.05).@*CONCLUSION@#TEAS combined with EA can accelerate the recovery of gastrointestinal function in patients after abdominal surgery, relieve postoperative pain, and shorten hospital stay.

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.

High frequency transcutaneous electrical stimulation in the immediate postoperative period of anterior cruciate ligament reconstruction: a randomized clinical trial / Estimulação elétrica transcutânea de alta frequência no pós operatório imediato de reconstrução do ligamento cruzado anterior: um ensaio clínico randomizado

INTRODUCTION: The anterior cruciate ligament (ACL) is an important structure for knee stability. Transcutaneous electrical nerve stimulation (TENS) is an electrical current applied for significant pain relief. OBJECTIVE: To evaluate the effects of high-frequency TENS on the immediate postoperative period of ACL reconstruction. METHODS: 46 patients in the postoperative period of ACL reconstruction were randomly assigned to a control group (CG=23) and a TENS group (TG=23). Knee range of motion (ROM), pain, muscle strength, and drug intake were assessed before surgery and 24 and 48 hours after surgery. The TENS intervention protocol started in the recovery room, shortly after surgery, and was maintained continuously for the first 48 hours after surgery. RESULTS: The TENS group (TG) significantly controlled the increased level of postoperative pain (p<0.05) and significantly increased flexion ROM (p<0.05). When compared to the Control group (CG), the TENS group had a lower intake of ketoprofen (48.27%), diazepam (256.98%), and dipyrone (121.21%), morphine (320.77%), and tramadol (437.46%). CONCLUSION: Continuous high-frequency TENS significantly reduced pain intensity and significantly improved ROM, muscle strength, and drug intake in the postoperative period of ACL reconstruction.

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.

Sex and age differences in sensory threshold for transcutaneous electrical stimulation / Diferenças de sexo e idade no limiar sensitivo para estimulação elétrica transcutânea

Abstract Introduction Pain is one of the main symptoms prevalent in most pathologies. Transcutaneous Electrical Nerve Stimulation (TENS) represents not only a therapeutic measure, but also a mean to quantify the neurosensory and pain perception in patients with chronic pain. Objective To evaluate the relationship between sex and age with neurosensory thresholds (sensory threshold and tolerance threshold) in the application of therapeutic current in patients with chronic pain. Methods Forty-five patients with chronic pain (30 women and 15 men) aged between 24 and 87 years were selected. Each patient answered the Individual Questionnaire, McGill Pain Questionnaire (MPQ) and Beck Depression Inventory (BDI). Subsequently, the electric current was applied, through which the sensory and pain thresholds were analyzed, as well as the perception of activation of the neurosensory pathways for each individual. Data were analyzed using the SPSS 24.0 for Windows. Results There was no significant correlation (p > 0.05) between a possible depressive diagnosis and the perception of current by the sensory and pain thresholds. Regarding sex, there was a significant difference in sensory thresholds (p = 0.003) between men and women, while no statistical differences were observed between sexes for pain complaint and pain threshold (p > 0.05). For the correlational analysis, a significant correlation (p = 0.05) was identified between the variables BMI and pain tolerance threshold (r = 0.68) for females and age and sensory threshold (r = 0.65) for males. Conclusion The sex and age variables are important in the measurement of TENS parameters because they lead to significant differences in sensory and pain thresholds.

Resumo Introdução A dor é um dos principais sintomas preva-lentes na maioria das patologias. A estimulação elétrica ervosa transcutânea (TENS) se apresenta não apenas como medida terapêutica, como também um meio de quantificar a percepção neurossensitiva e dolorosa em pacientes com dores crônicas. Objetivo Avaliar a relação entre sexo e idade com os limiares neurossensitivos (limiar sensitivo e limiar de tolerância) na aplicação da corrente terapêutica TENS, em pacientes com dores crônicas. Métodos Foram selecionados 45 pacientes com dores crônicas (30 mulheres), com idade entre 24 e 87 anos. Cada paciente respondeu ao Questionário Individual, ao Questionário McGill de Dor (MPQ) e ao Inventário de Depressão de Beck (BDI). Posteriormente, aplicou-se a corrente elétrica TENS, pela qual foram analisados o limiar sensitivo e doloroso, bem como a percepção de acionamento das vias neurossensitivas para cada indivíduo. Os dados foram analisados pelo pacote SPSS 24.0 for Windows. Resultados Não houve correlação significativa (p > 0,05) entre possível diagnós-tico depressivo e a percepção da corrente pelos limiares de sensibilidade e dor. Em relação ao sexo, houve diferença significativa nos limiares sensitivos (p = 0,003) entre homens e mulheres. Já para a queixa de dor e limiar de dor, não foram observadas diferenças estatísticas entre os sexos (p > 0,05). Para as análises correlacionais, identificou-se correlação significativa (p = 0,05) entre as variáveis de índice de massa corporal e limiar de tolerância à dor (r = 0,68) para o sexo feminino e idade e limiar sensitivo (r = 0,65) paro o sexo masculino. Conclusão As diferenças identificadas entre os limiares de sensibilidade entre os sexos, onde as mulheres identificaram o estímulo elétrico significativamente primeiro que os homens, podem auxiliar nas doses de intensidade ou tipo de corrente terapêutica dos pacientes.

La electroestimulación neuromuscular como mecanismo complementario en el entrenamiento deportivo de predominancia anaeróbica / Neuromuscular electro-stimulation as a complementary mechanism in sports training of anaerobic predominance

Introducción: La electroestimulación neuromuscular puede dar un valor agregado a los programas de ejercicio físico de rehabilitación, siempre y cuando se contemplen aspectos como los objetivos propios de cada persona, la tolerancia a la intensidad y las necesidades de recuperación y descanso. Así mismo, puede ser un elemento interesante a agregar en la planificación deportiva con miras a mejorar la recuperación, así como en el aumento del rendimiento físico. Objetivo: El objetivo principal de la presente investigación fue determinar los efectos del ejercicio combinado de electroestimulación neuromuscular y ejercicios de alta intensidad y corta duración en hombres sanos y físicamente activos sobre el índice de fatiga. Metodología: 34 hombres sanos, físicamente activos y estudiantes de educación física (19,4 ± 2,60 años) fueron aleatorizados y organizados en cuatro grupos: G1, programa de electroestimulación neuromuscular; G2, entrenamiento de alta intensidad y corta duración: G3, ejercicio combinado de alta intensidad y corta duración y, electroestimulación neuromuscular; y G4, grupo control. Se aplicó un test de Wingate antes y después del periodo de entrenamiento. Resultados: En el grupo G3 se evidencian aumentos en el rendimiento anaeróbico con diferencias significativas en la potencia promedio relativa al peso (p=0,027), con un aumento de 7,36% y con una disminución de 12,2% en el índice de fatiga (p=0,048). En el grupo G4 se evidencian disminuciones en el rendimiento, evidenciado a través de las diferencias significativas en la potencia media (p=0,030), con una disminución en el rendimiento de 6,32% y una disminución en el rendimiento en la potencia media relativa al peso con diferencia significativa (p=0,010) de 3,92%. Conclusiones: Un programa combinado de electroestimulación neuromuscular y ejercicio intervalico de alta intensidad mejora el rendimiento anaeróbico en la potencia media y relativa al peso, evidenciado a través de un test de Wingate. Así mismo, disminuye el porcentaje de caída del rendimiento anaeróbico, mostrando mejores resultados frente a un entrenamiento de solo ejercicio intervalico de alta intensidad

Introduction: Neuromuscular electrostimulation can add value to rehabilitation physical exercise programs, as long as aspects such as the objectives of each person, tolerance to intensity, and the needs for recovery and rest are considered. Likewise, it can be an interesting element to add in sports planning with a view to improving recovery, as well as increasing physical performance. Objective: The main objective of this research was to determine the effects of combined neuromuscular electrostimulation exercise and high intensity and short duration exercises in healthy and physically active men on the fatigue index. Methodology: 34 healthy, physically active, and physical education male students (19.4 ± 2.60 years) were randomized and organized into four groups: G1, neuromuscular electrostimulation program; G2, high intensity and short duration training; G3, combined exercise of high intensity and short duration, and neuromuscular electrostimulation; and G4, control group, A Wingate test was applied before and after the training period. Results: In the G3 group, there are increases in anaerobic performance with significant differences in the average power relative to weight (p=0.027), with an increase of 7.36%, and a decrease of 12.2% in the fatigue index (p=0.048). In the G4 group there are decreases in performance, evidenced through the significant differences in the average power (p = 0.030), with a decrease in performance of 6.32% and a decrease in the performance in mean power relative to weight with a significant difference (p=0.010) of 3.92%. Conclusions: A combined program of neuromuscular electrostimulation and high-intensity interval exercise improves anaerobic performance in mean power and relative to weight, evidenced through a Wingate test. Likewise, it decreases the percentage of drop in anaerobic performance, showing better results in comparison to training with only high-intensity interval training

Parasacral transcutaneous electrical nerve stimulation in children with overactive bladder: comparison between sessions administered two and three times weekly

ABSTRACT Purpose: This study compares the results achieved following parasacral TENS administered using two different weekly schedules. Materials and Methods: Children of at least four years of age with a diagnosis of pure overactive bladder were included in this randomized clinical trial and treated with parasacral TENS (2 versus 3 sessions per week). All the participants also underwent standard urotherapy. Results: Sixteen children were included in the twice-weekly group and eighteen in the three times weekly group. There were no statistically significant differences between the two groups with respect to sex; however, there was a difference in age. There were no significant differences regarding complete resolution of urinary symptoms, with 8 children (50%) in the twice-weekly group and 11 children (61%) in the three times weekly group having their symptoms completely resolved (p=0.73). There was a significant difference in the DVSS score in both groups following TENS treatment compared to baseline (p=0.0001 for both groups), but not between groups. Evaluation of the bladder diary showed no difference between the groups before or after treatment. Conclusion: For children with overactive bladder who are unable to undergo parasacral TENS treatment three times weekly, the method can be administered successfully at twice-weekly sessions.

Estimulação elétrica nervosa transcutânea interativa e convencional em mulheres com dismenorreia primária / Interactive and conventional transcutaneous electrical nerve stimulation in women with primary dysmenorrhoea

A dismenorreia primária é uma dor na região inferior do abdômen, antes ou durante a menstruação e independente de patologias pélvicas. Tratamentos fisioterapêuticos são alternativas para a melhora dos sintomas, dentre esses recursos, a estimulação elétrica nervosa transcutânea (TENS). O objetivo deste estudo foi comparar o efeito terapêutico e analgésico da TENS interativa e convencional na dor secundária à dismenorreia primária. A aplicação da TENS, em ambos os grupos, foi realizada no primeiro dia do período menstrual por 35 minutos. Na TENS interativa todas as voluntárias optaram pelos seguintes parâmetros: frequência de 250 Hz, duração de pulso de 25 µs e intensidade conforme nível sensorial, sendo essa ou a duração do pulso reajustado, a cada 5 minutos, conforme houvesse necessidade. Na TENS convencional foi utilizado os seguintes parâmetros: frequência de 100 Hz, duração de pulso de 50 µs e com a intensidade conforme grupo anterior. A análise estatística foi realizada por meio do software GraphPadPrism®, versão 5.0, sendo empregado o teste t de Student e com nível de significância de p < 0,05. Obteve-se como resultado uma redução da dor entre as participantes de ambos os grupos logo após o tratamento. Porém não houve diferença na analgesia promovida pelos dois métodos de tratamento. (AU)

Primary dysmenorrhea (PD) is a lower region of the abdomen pain, before or during menstruation and independent of pathologies. Physical therapy treatments are alternatives to improve symptoms, among these resources, transcutaneous electrical nerve stimulation (TENS). The aim of this study was to compare the therapeutic and analytical effect of interactive and conventional TENS in high school in PD. The application of TENS, in both groups, was performed on the first day of the menstrual period for 35 minutes. In the interactive TENS all the volunteers chose the following parameters: frequency of 250 Hz, pulse duration of 25 µs and intensity according to sensory level, whether this or the duration of the readjustment of the pulse, every 5 minutes, according to the need for use. In conventional TENS, the following parameters were used: frequency of 100 Hz, pulse duration of 50 µs and intensity according to the previous group. A statistical analysis was performed using the GraphPadPrism® software, version 5.0, being employed Student's test with a significance level of p < 0.05. The result is a reduction in pain among participants in both groups right after treatment. However, there was no difference in the analgesia promoted by the two treatment methods. (AU)

Estimulação elétrica neural transcutânea (tens) na paroxismia do tronco cerebral: relato de caso / Transcutaneous electrical nerve stimulation (tens) in brain stem paroxysms: case report

INTRODUÇÃO: A paroxismia de tronco encefálico, descrita em pacientes com esclerose múltipla (EM), caracteriza-se por episódios rápidos de vertigem e nistagmos evocados por movimentos cefálicos. A neuromodulação tem apresentado sucesso terapêutico em várias disfunções da EM, mas ainda não foi utilizada na paroxismia. OBJETIVO: Avaliar o efeito aditivo da neuromodulação por estimulação elétrica neural transcutânea (TENS) na musculatura periocular em paciente com EM e paroxismia de tronco encefálico não responsiva à reabilitação clássica associada à medicação. MATERIAL E MÉTODOS: Avaliação do nistagmo com videonistagmógrafo, da sensibilidade cutânea facial com estesiômetro, do blefaroclônus por gravação em vídeo e da sensação dolorosa de forma subjetiva (descrição pessoal da paciente); execução de 10 sessões consecutivas semanais de exercícios oculares associados à TENS na musculatura do oblíquo inferior e reto lateral direitos. RESULTADO: Melhora da algia, do blefaroclônus, da vertigem e do nistagmo ocular direito. CONCLUSÃO: A neuromodulação com TENS parece ser uma terapia complementar válida para pacientes com EM e paroxismia de tronco não responsivos aos demais tratamentos clínicos, porém mais estudos são necessários para confirmar esse achado.

INTRODUCTION: Brainstem paroxysmia has been described in patients with multiple sclerosis, characterized by rapid episodes of nystagmus and vertigo evoked by cephalic movements. Neuromodulation has shown therapeutic success for several dysfunctions of multiple sclerosis, but it has not yet been used in paroxysmia. OBJECTIVE: To assess the additive effect of neuromodulation by transcutaneous electrical neural stimulation (TENS) on the periocular musculature in a patient with multiple sclerosis and brain stem paroxysmia that is not responsive to classical rehabilitation associated with medication. MATERIAL AND METHODS: Nystagmus evaluation with video nystagmography, facial skin sensitivity analysis with esthesiometer, video recording of blepharoclonus, and pain sensation subjectively quantification (by a personal description of the patient); execution of 10 eyes consecutive exercises sessions associated with TENS in the right lower oblique and lateral rectus muscles. RESULT: Improvement in pain, blepharoclonus, and right eye nystagmus. CONCLUSION: Neuromodulation with TENS seems to be a valid complementary therapy for patients with brainstem paroxysmia unresponsive to other clinical treatments, but more studies are needed to confirm this finding.

Introducción: El objetivo de este estudio fue evaluar el impacto de la pandemia de Covid-19 en la práctica de la Neuromodulación en Argentina. Material y Métodos: Se envió una encuesta a los profesionales que practican la Neuromodulación en Argentina entre el 19 de julio al 20 de agosto de 2020. Se determinó el impacto de Covid-19 a nivel profesional y personal. Todas las variables fueron comparadas y analizadas. Resultados: Veinticuatro profesionales respondieron a la encuesta completa. La mayoría de ellos eran varones (87,5%), en el grupo de edad de 45 a 59 años (37,5%), con 15 o más años de experiencia (45,83%). Los neurocirujanos fueron la mayoría (87,5%), siendo las técnicas ablativas la práctica predominante (26,47%). La gran mayoría informó una disminución de las prácticas quirúrgicas (83,33%), entre el 50 y el 74% de ellas (40%), siendo la decisión del financiador la razón única más citada (43,47%) y la Estimulación Cerebral Profunda, la técnica quirúrgica más afectada (41,6%). El 100% de los entrevistados declaró que los pacientes habían sido perjudicados por la suspensión de cirugías y que los ingresos económicos se redujeron de alguna manera, también en el 100% de los encuestados. A nivel personal, ninguno de los profesionales reportaron haber sido diagnosticados de la enfermedad. Sin embargo, el 37,5% sufrió algún otro tipo de daño a nivel físico y el 20,83% informó secuelas psicológicas, especialmente ansiedad. Conclusión: La actual pandemia de Covid-19 ha tenido un impacto muy significativo en la práctica de la Neuromodulación en Argentina, tanto a nivel profesional como personal. Este impacto debe ser tenido en cuenta en el futuro, en caso de una nueva pandemia, para prevenir los efectos nocivos que se registraron en este estudio

Background: The objective of this study was to evaluate the impact of the Covid-19 outbreak in the practice of Neuromodulation in Argentina. Methods: A survey was sent to Argentina neuromodulation practitioners from July 19 to August 20, 2020. The impact of Covid-19 on the professional and personal level were determined. All variables were compared and analyzed. Results: Twenty-four practitioners responded to the complete survey. Most of them were male (87.5%), in the 45-59 year age group (37.5%), with 15 or more years of experience (45.83%). Neurosurgeons were in the majority (87.5%), with ablative techniques being the predominant practice (26.47%). The great majority reported a decrease in surgical practices (83.33%), between 50 and 74% of them (40%), with the decision of the financer being the most cited reason (43.47%), and Deep Brain Stimulation the most affected surgical technique (41.6%). 100% of the interviewed declared that the patients had been harmed by the suspension of surgeries, and that the economic income was reduced in some way in 100% of the interviewed. On a personal level, none of the professionals reported having been diagnosed with the disease. However, 37.5% suffered physical manifestations, and 20.83% reported psychological sequelae, especially anxiety. Conclusion: The current Covid-19 pandemic yielded a significant impact on the daily work practice as well as on the personal level of practitioners in neuromodulation in Argentina. This impact must be taken into account in the long term to avoid further harmful effects and their sequels and to take appropriate preventive measures in the event of another pandemic
