Evaluating Dielectric Properties for Assessing Water Content at Acupuncture Points: New Methodology.

Importance: Understanding acupuncture point microenvironments is vital for optimizing treatment efficacy. Evaluating changes in water content at these points can provide further insights into the effects of acupuncture on tissues. Objective: This study aimed to measure tissue dielectric constant (TDC) and assess changes in water content, specifically at stomach 36 (ST36, Zusanli) and spleen 6 (SP6, Sanyinjiao) acupuncture points. Methods: In a controlled, blinded, randomized trial, 113 healthy volunteers were divided into six groups based on TDC sensor diameters (XS, M, and L): three control groups and three acupuncture groups. They were assessed at three time points: T1, baseline; T2, 20 min post-needle withdrawal; and T3, 40 min post-needle withdrawal. Electrical impedance (EI) was also analyzed. Significance level was set at p < 0.001. Results: TDC at ST36 and SP6 significantly decreased with the XS probe at T2 and T3 compared with that at T1 (F8, 452: 54.61). TDC did not significantly vary between T2 and T3 with M and L probes. EI data indicated that the current passage increased in the SP (F2, 226: 39.32) and ST (F2, 226: 37.32) groups during T2 and T3 compared with that during T1 within their respective groups and controls. Conclusions: and Relevance: This study demonstrated the efficacy of TDC measurements in detecting water content fluctuations at acupuncture points and their responses to needles. TDC measurements, which were validated against EI, provide valuable insights into acupuncture point microenvironments and thus help optimize treatments.

Parameters and results of non-invasive neuromodulation in the management of chronic pelvic pain: integrative literature review / Parâmetros e resultados da neuromodulação não invasiva no manejo da dor pélvica crônica: revisão integrativa da literatura

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic Pelvic Pain (CPP) is characterized by persistent pain in the pelvic region for more than six months, affecting both men and women and causing significant impairment in quality of life (QoL). Two of the main non-invasive approaches are Transcranial Magnetic Stimulation (TMS) and Transcranial Direct Current Stimulation (tDCS). These techniques aim to modulate neural activity and promote pain relief. In this context, this research conducted an integrative literature review to summarize the results of relevant studies, aiming to identify the key parameters used in TMS and tDCS for CPP treatment. The objective was to assess the effect and efficacy of non-invasive neuromodulation as a therapeutic intervention for CPP. CONTENTS: For this integrative review, electronic searches were conducted in Pubmed, Scielo, PEDro, Medline, Cochrane, and Scopus databases, examining studies in Portuguese, English, or Spanish. The keywords "pelvic pain," "transcranial direct current stimulation," and "transcranial magnetic stimulation" and their derivatives were searched in the three languages in studies from 2013 to 2023. Seven studies were included for analysis. Both techniques showed positive effects in managing CPP, improving pain levels and quality of life to a relevant extent. However, there is still no consensus on the parameters applied in TMS and tDCS techniques for CPP. CONCLUSION: Non-invasive neuromodulation improves pain levels and quality of life in patients with CPP. Further studies are needed to establish more reliable parameter relationships, and the limited number of studies restricts definitive conclusions on the subject.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor pélvica crônica (DPC) é caracterizada pela persistência da dor na região pélvica por mais de seis meses, afetando tanto homens quanto mulheres e causando prejuízos significativos na qualidade de vida (QV). Duas das principais abordagens não invasivas são Estimulação Magnética Transcraniana (EMT) e a Estimulação Transcraniana por Corrente Contínua (ETCC). Nesse contexto, esta pesquisa realizou uma revisão integrativa da literatura com o intuito de resumir os resultados de estudos relevantes, buscando identificar os principais parâmetros utilizados no tratamento da DPC. O objetivo foi fornecer uma visão abrangente sobre essas técnicas de neuromodulação e suas aplicações específicas no controle da dor pélvica crônica. CONTEÚDO: Para esta revisão integrativa, as buscas eletrônicas ocorreram nas bases de dados Pubmed, Scielo, PEDro, Medline, Cochrane e Scopus, verificando estudos em português, inglês ou espanhol. "Dor pélvica", "estimulação transcraniana por corrente contínua" e "estimulação magnética transcraniana" e suas derivações foram pesquisadas nos três idiomas em estudos entre 2013 e 2023. Sete estudos foram incluídos para análise. Ambas as técnicas apresentaram efeitos positivos no manejo da DPC, melhorando os níveis de dor e a QV em proporções relevantes. Entretanto, ainda não há um consenso sobre os parâmetros aplicados nas técnicas de EMT e ETCC para DPC. CONCLUSÃO: A neuromodulação não invasiva melhora os níveis de dor e a QV em pacientes com DPC. São necessários mais estudos para que relações mais confiáveis de parâmetros possam ser preestabelecidas e a ausência de um maior número de estudos limita conclusões acerca do assunto.

Validation of the Brazilian version of Knowledge and Attitudes of Pain questionnaire / Validação da versão brasileira do questionário Knowledge and Attitudes of Pain

ABSTRACT BACKGROUND AND OBJECTIVES: Health professionals attitudes and beliefs about musculoskeletal pain have a negative influence on patient beliefs and outcomes. However, there is no gold standard for assessing knowledge and attitudes toward pain among these professionals. Thus, the objective of the present study was to translate, adapt and validate the Knowledge and Attitudes of Pain (KNAP) questionnaire into Brazilian Portuguese (KNAP-Br), apply the questionnaire and analyze the correlation of its results with the Neurophysiological Pain Questionnaire (NPQ). METHODS: After being translated, back-translated and adapted, the NKAP-Br was applied to 60 physical therapy and medicine students for validation. The correlation between the results obtained by multiplying the scores of the questions of the NKAP-Br instrument and the NPQ was evaluated. To assess reliability, another 200 students responded to the initial KNAP-Br (T1), performed the Pain Education Program (PEP) in one week and one week after T1, the participants received access to answer the KNAP-Br end (T2). RESULTS: Concurrent validity was assessed by the correlation between NPQ and the final KNAP-Br score. A significant correlation was found between the NPQ result (0.3 and p-value=0.0001) and the KNAP-Br score. Intragroups, 84% improved in the KNAP-Br score after studying PEP, 43.50% improved at or above the minimal detectable difference (MDD) and at or above the minimal important difference (MID). CONCLUSION: The questionnaire was translated and adapted respecting the Brazilian population cultural aspects and presented satisfactory reliability and construct validity, being considered valid for the assessment of knowledge and the interpretation of pain by health professionals.

RESUMO JUSTIFICATIVA E OBJETIVOS: As atitudes e as crenças dos profissionais de saúde sobre dor musculoesquelética têm influência negativa nas crenças e resultados dos pacientes. Entretanto, não existe um padrão ouro para avaliar o conhecimento e as atitudes relativas à dor entre esses profissionais. Dessa forma, o objetivo deste estudo foi traduzir, adaptar e validar o questionário Knowledge and Attitudes of Pain (KNAP) para a língua portuguesa brasileira (KNAP-Br), aplicar o questionário e analisar a correlação dos seus resultados com o Questionário Neurofisiológico de Dor (QND). MÉTODOS: Após ser traduzido, retrotraduzido e adaptado, o KNAP-Br foi aplicado em 60 estudantes de fisioterapia ou medicina para validação. Foi avaliada a correlação entre os resultados obtidos pela multiplicação dos escores das questões dos instrumentos KNAP-Br e QND. Para avaliação da confiabilidade, outros 200 estudantes responderam o KNAP-Br inicial (T1), realizaram em uma semana o Programa de Educação em Dor (PED) e uma semana após T1 os participantes receberam acesso para responder o KNAP-Br final (T2). RESULTADOS: A validade concorrente foi avaliada pela correlação entre QND e o escore final do KNAP-Br. Foi encontrada uma correlação significativa entre o resultado do QND (0,3 e valor de p=0,0001) e o escore do KNAP-Br. Intragrupos, 84% melhoraram no escore do KNAP-Br após estudar PED, 43,50% melhoraram igual ou acima da menor diferença detectável (MDD) e igual ou acima da diferença mínima importante (DMI). CONCLUSÃO: O questionário foi traduzido e adaptado, respeitando os aspectos culturais da população brasileira, e apresentou satisfatória confiabilidade e validade de constructo, sendo considerado válido para avaliação do conhecimento e para a interpretação da dor por profissionais de saúde.

Participation of Potential Transient Receptors in the Antinociceptive Effect of Pharmacopuncture.

Background: Despite the widespread clinical use of acupuncture in painful situations, the use of this treatment should be further clarified. Nociception is mediated by the activation of nociceptors, such as transient receptor potentials (TRPs). The family of TRPs includes TRPV1, TRPM8, and TRPA1, which can be stimulated by substances such as capsaicin, menthol, and methyl salicylate, respectively. Objectives: This study aimed to investigate the role of TRPs in antinociception via the administration of agonists of these receptors in the Zusanli acupoint (ST36) in models of inflammatory, acute, and neuropathic pain. Methods: Male Wistar rats were used for this experiment. All rats received a subcutaneous injection of TRP agonists (capsaicin, menthol, or methyl salicylate) in ST36; saline was injected as control. Nociception was evaluated using the electronic mechanical threshold test and tail-flick test before the administration of complete Freund's adjunct or chronic constriction injury of the sciatic nerve and after the administration of TRP agonists. Results: Nociception was found to be attenuated after treatment with TRP agonists. The administration of different doses (0.03, 0.3, and 3.0 µg/20 µL) of capsaicin, menthol, and methyl salicylate in the different pain models (neuropathic, inflammatory, and nociceptive) induced antinociception in most of the evaluated time points. Conclusion: Based on the findings, we suggest that the activation of TRPV1, TRPM8, and TRPA1 receptors results in the antinociceptive effect of the stimulation of the ST36 acupoint. Thus, TRP receptors may present a new therapeutic opportunity for the control of inflammatory and neuropathic pain.

Role of education after the COVID-19 pandemic fear: a multidisciplinary and scientific perspective / Papel da educação após o medo pandêmico do COVID-19: uma perspectiva multidisciplinar e científica

In response to the outbreak of the novel Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), pathogen of the new coronavirus disease (COVID-19), several sectors and social activities have been affected, including education. At first, it is explained that educators and students can feel fragile during and after the SARS-CoV-2 outbreak. Subsequently, it is discussed that their relationship ought to be carefully established given the triggering of psychological and neuropsychiatric effects arising from neural coding and plasticity processes, which result in the formation of positive and negative memories in the short to long term. Finally, it is pointed out that the SARS-CoV-2 pandemic generates a need for adequacy and adaptation for the significant attention to students during the re-starting of studies, given that possible disorders of sensory modulation and involvement of limbic brain areas triggered in situations of risk of death, potential or real threat, can happen. It is assumed that at times of the SARS-CoV-2 pandemic, in addition to preserving life, one of the challenges is the behavioural (re)organisation, which includes habits from the educational context that need to contemplate a scientific perspective, seeking to transform the consequences of the pandemic fear on opportunities to reinforcement of familiar links. In the context of modern rationality, the SARS-CoV-2 pandemic is also a period to think about the relationship between scientific knowledge and common sense. With this logic, neurosciences can develop a new format for the teaching-learning process, so that educators and students experiencing the pandemic threatening do not manifest psychological distress and secondary consequences. Therefore, education can be considered a central space in decision-making in the face of SARS-CoV-2 pandemic. In this sense, the urgency of a multidisciplinary strategies development is highlighted, connecting the synergy between neurosciences and education after the COVID-19 pandemic.

Prevalence and characteristics of chronic pain in Brazil: a national internet-based survey study / Prevalência e características da dor crônica no Brasil: um estudo nacional baseado em questionário pela internet

ABSTRACT BACKGROUND AND OBJECTIVES: The prevalence of chronic pain has been increasing in the world, and it is considered the most underestimated health care problem impacting the quality of life. Furthermore, there is little consensus regarding the burden of chronic pain in Brazil. The present study aimed to investigate the prevalence of chronic pain in the general Brazilian adult population, and the socio-demographic, clinical, medical conditions and pain locations on the body. METHODS: A cross-sectional Internet-based survey was conducted in a nationally representative sample of Brazil adults to estimate the prevalence, sociodemographic correlates and characteristics of chronic pain in the Brazilian population. Twenty-seven-thousand and three hundred forty-five (27,345) representative residents were contacted. RESULTS: From 27,345 individuals, 20,830 (76.17%) presented chronic, recurrent, or long-lasting pain, lasting for at least 6 months. Nearly half of the respondents were 65 years older (48.15%) and the prevalence was higher in females (84,60%) than males (16.40%). The prevalence of primary chronic lower back pain was 59.85%; of primary rheumatoid arthritis was (59.78%) and primary osteoarthritis pain was 69.02%. Half of the respondents with chronic pain experienced daily pain, and average (past 3 months) pain intensity was moderate at 57.28%. CONCLUSION: Chronic pain affects more than two-thirds of the population of Brazil. Our findings revealed a high prevalence and severity of chronic pain and suggested that it is a public health problem in Brazil. Risk factors are being a woman, advanced age and low levels of household income. There is a need for improved health policies in Brazil for patients with chronic pain.

RESUMO JUSTIFICATIVA E OBJETIVOS: A prevalência de dor crônica tem aumentado no mundo e é considerada o problema de saúde mais subestimado, com impacto na qualidade de vida. Além disso, há pouco consenso em relação à carga da dor crônica ao sistema de saúde no Brasil. O presente estudo teve como objetivo investigar a prevalência de dor crônica na população adulta geral brasileira e as condições sociodemográficas, clínicas, médicas e a localização corporal da dor. METODOS: Foi realizado um estudo transversal, em questionário pela internet em uma amostra nacionalmente representativa de adultos do Brasil, para estimar a prevalência e características da dor crônica na população brasileira. Vinte e sete mil e trezentos e quarenta e cinco (27.345) residentes representativos foram contatados. RESULTADOS: Dos 27.345 indivíduos, 20.830 (76,17%) apresentaram dor crônica, recorrente ou duradoura com duração de pelo menos 6 meses. Quase metade dos entrevistados tinham mais de 65 anos de idade (48,15%) e a prevalência era maior nas mulheres (84,60%) do que nos homens (16,40%). A prevalência de dor lombar crônica primária foi de 59,85%; de artrite reumatoide primária foi (59,78%) e dor primária oriunda de osteoartrite foi de 69,02%. Metade dos entrevistados com dor crônica apresentava dor diária e a intensidade da dor média (últimos 3 meses) era moderada em 57,28%. CONCLUSÃO: A dor crônica afeta mais de dois terços da população do Brasil. Os resultados deste estudo revelaram alta prevalência da dor crônica. Os fatores de risco são ser mulher, idade avançada e baixos níveis de renda familiar. Há necessidade de melhores políticas de saúde para pacientes com dor crônica no Brasil.

Lower limb auriculotherapy points improves balance in young healthy subjects-assessed by computerized baropodometry.

OBJECTIVE: To analyze the effects of Lower Limb (LL) auricular stimulation points on the static equilibrium of healthy subjects, assessed by computerized baropodometry. METHODS AND MATERIALS: Forty volunteers were assigned to one of two groups: Auriculotherapy (AT) who received unilateral needle stimulation of the coxofemoral, knee, and ankle points. Control (C) who did not receive any stimulation. We analyzed the contact area (CA) and the peak pressure (PP) for both feet at baseline, 20 and 25 min after the baseline was recorded. Three-Way ANOVA (P < 0.05) was used for data analysis. RESULTS: AT showed an increase in CA (F:6.49) and a decrease in PP (F:3.11) at 20 and 25 min, when compared to C. The PP decreased was only for the right LL at 20 and 25 min (F:6.45). CONCLUSION: The auriculotherapy points were able to modify the ipsilateral weight discharge on the same side of the stimulated auricular pavilion.

Experiencing early life maternal separation increases pain sensitivity in adult offspring.

Maternal separation is a widely accepted model for studying long-term behavioral changes produced by events during early life and its association with changes in pain sensitivity. Thus, our objective was to evaluate sensitivity to pain, under different stimuli in adult male and female rats that had undergone early life maternal separation. Animals were subjected to maternal separation from postnatal day (PND) 2-15. Maternal behavior and litter weight were evaluated during this period. Sensitivity to pain was assessed in offsprings during adulthood by exposing them to stimuli, including formalin (5%; 20µl), a hot plate, and the electronic von Frey test, 4, 7, 10, and 24h after the administration of saline or Freund's complete adjuvant (CFA) injection. Maternal separation did not affect maternal behavior or litter weight during PND 2-15. However, experiencing maternal separation increased pain sensitivity in the rats subjected to formalin by increasing number of flinches and licking time Further, females appeared more sensitive than males to thermal stimuli, as they showed a decrease in latency in the hot plate test. In this test, male and female offsprings that were exposed to early life maternal separation and received the CFA injection also showed a reduction in latency to react to the painful stimuli. In the von Frey test, there was a reduction in withdrawal threshold in maternal separation animals injected with CFA, thus demonstrating a greater sensitivity to the mechanical stimuli. In conclusion, experiencing early life maternal separation increased pain sensitivity in adult offsprings. Thus, our data are important to understand the impact of environmental influences, such as stressful life events during critical developmental periods, on pain vulnerability.

Efeitos do resfriamento e aquecimento articular no desempenho funcional do ombro / Effects of cooling and heating on shoulder functional performance / Efectos del enfriamiento y del calentamiento articular del hombro en el desempeño funcional

INTRODUÇÃO: Um dos recursos mais utilizados na reabilitação de lesões musculoesqueléticas é a termoterapia por subtração de calor (crioterapia), enquanto a termoterapia por adição de calor é considerada o procedimento mais antigo de reabilitação física. Entretanto, há poucas evidências que tenham investigado os efeitos desses recursos sobre o desempenho de membros superiores. OBJETIVO: Comparar o efeito do resfriamento e do aquecimento articular sobre o desempenho funcional do membro superior. MÉTODOS: Trinta e quatro voluntários (22,23 ± 2,17 anos; 22,39 ± 2,53 kg/m2), de ambos os sexos, foram divididos aleatoriamente em um dos três grupos: 1) grupo crioterapia GCR (n=10): submetidos ao resfriamento articular por compressas frias; 2) grupo termoterapia - GTE (n=10): submetidos ao aquecimento articular por ondas curtas e 3) grupo controle - GCO (n=14), não submetidos a qualquer intervenção. Os voluntários foram avaliados, pré e pós-intervenção, quanto ao desempenho funcional de membros superiores por meio dos testes de estabilidade da extremidade superior em cadeia cinética fechada (TEESCCF) e das condições de equilíbrio em apoio bimanual sobre o baropodômetro. Ainda, os voluntários foram avaliados quanto ao desempenho funcional virtual por meio do jogo Mario Kart (Nintendo Wii (r) ). RESULTADOS: Houve melhora significativa nos valores pós-intervenção no TEESCCF para o GCR (p<0,001), GTE (p=0,002) e GCO (p=0,01). Não houve alteração significativa na área de deslocamento do centro de pressão na condição de olhos abertos, nos três grupos (p>0,05). Entretanto, na condição de olhos fechados, houve piora de desempenho para GTE (p=0,04) e melhora de desempenho para o GCO (p=0,02). Não houve alteração significativa no desempenho funcional virtual para os três grupos (p>0,05). CONCLUSÃO: Embora não tenha favorecido o desempenho funcional em todos os testes reais e virtuais utilizados, o resfriamento articular foi mais efetivo que o ...

INTRODUCTION: Thermotherapy by heat subtraction or cryotherapy is one of the most used resources in the physical rehabilitation whereas thermotherapy by addition of heat is considered as the oldest procedure in physical rehabilitation. However, there are few evidences regarding the effects of these physical agents on the performance of upper limbs. OBJECTIVE: To compare the effect of joint cooling and joint heating on functional performance of the upper limb. METHODS: Thirty-four subjects (22.23 ± 2.17 years old; 22.39 ± 2.53 kg/m2) of both genders were randomly assigned to one of the following three groups: 1) subjects who were submitted to joint cooling with cold compresses - CRG (n=10); 2) subjects who were submitted to joint heating by shortwave thermotherapy - THG (n=10) and 3) subjects who were not submitted to any intervention - control group - COG (n=14). Upper limb performance was assessed pre- and post-intervention by the closed kinetic chain upper extremity stability test (CKCUEST). Balance conditions were assessed in upper limb supporting on a pressure platform. Virtual performance was evaluated by Mario Kart Wii game (Nintendo Wii(r)). RESULTS: There was significant improvement in post intervention measurements in CKCUEST for both CRG (p<0.001), THG (p=0.002) and COG (p=0.01). There were no significant changes in the center of pressure area displacement with opened eyes in the three groups (p> 0.05). However, in the closed eyes condition, there was a worsened performance for THG (p=0.04) and improved performance for COG (p=0.02). No significant changes in virtual performance were observed for the three groups (p>0.05). CONCLUSION: Joint cooling was more effective than joint heating to maintain the upper limb muscle performance, especially in upper limb balance with closed eyes although it did not favor functional performance in all real and virtual tests. .
