Dataset on bilateral idiopathic carpal tunnel syndrome: Crossover study of two combined physiotherapeutic treatment methods on chirurgical and clinical patients.

This study presents a randomized controlled crossover experiment involving 73 patients with idiopathic bilateral Carpal Tunnel Syndrome (CTS). Patients received two combined physiotherapeutic treatments: myofascial mobilization (IASTM) and stretching. Participants were divided into two groups: one started with stretching followed by IASTM, and the other with IASTM followed by stretching. Of these, 43 underwent surgery and began physical therapy 30 days post-operation, while 30 received non-surgical treatment. The therapy sessions lasted four weeks, followed by a crossover of the treatment modalities and periodic reassessments up to six months. The dataset includes experimental design, patient demographics, diagnostic data, objective muscle strength tests, subjective sensitivity tests, clinical indicators, and self-reported measures. This data can be useful for researchers looking to replicate the study or compare outcomes between clinical and surgical CTS patients.

Does kinesio tape alter muscle strength in athletes? - Systematic review and meta-analysis.

BACKGROUND: Kinesio tape (KT) is still a matter of debate and the results of studies that evaluated its effects on muscle strength in athletes are still contradictory and inconclusive. OBJECTIVES: To analyze randomized clinical trials (RCT) to compare the effects of KT on muscle strength with the control/placebo group among athletes with and without musculoskeletal injury. METHOD: The search involved the databases: PubMed, Web of Science, LILACS, PEDro, The Cochrane Library, Medline, Scopus, SPORTDiscus and Embase, without filter and included RCTs evaluating the effects of KT on muscle strength in athletes with or without musculoskeletal injury, comparing it to a control/placebo intervention. The following were excluded: studies with duplicate information; who used instruments for indirect assessment of muscle strength; involving a different population of athletes. Meta-analysis calculations were performed using post-intervention muscle strength data in the Review Manager (RevMan) program. RESULTS: 10 articles were eligible, among which 5 studies were included in the meta-analysis. In the primary analysis, no relevant clinical effect was found (immediate post-intervention <24h: Z = 1.97 CI95% = 0.35[0.00-0.70]; p = 0.05 I2 = 0% and late post-intervention ≥24h: Z = 1.47 CI95% = 0.59[-0.20-1.38]; p = 0.14 I2 = 69%) when comparing the KT group with the control/placebo groups for muscle strength of lower limbs in participants with and without musculoskeletal injury and in the subgroup analysis (including only individuals without injury), there was also no clinical effect (Z = 1.50, 95%CI = 0.31[-0.10-0.71] p = 0.13, I2 = 0%) of KT for muscle strength. CONCLUSIONS: KT does not contribute to muscle strength gain in athletes with and without musculoskeletal injuries. PROSPERO: CRD42020139822.

Plasma Levels of Interferon Gamma associated with Hearing Loss and Hearing Loss Sensation through the Handicap Questionnaire Inventory for the Elderly Screening Version.

OBJECTIVE: The aim of this study was to verify the association between the auditory handicap found in the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S) questionnaire and hearing loss and the plasma levels of inflammatory biomarkers. MATERIALS AND METHODS: Cross-sectional study with 76 participants, 67 (88%) females and 9 (12%) males, with a mean age of 70 years. Tonal threshold audiometry and self-assessment with HHIE-S questionnaire were performed to measure the plasma levels of interleukin-2 (IL-2), IL-4, IL-6, and IL-10; tumor necrosis factor alpha; and interferon gamma (IFN-γ) flow cytometry method. For all data analyzed, the significance level adopted was P < 0.05 and 95% confidence interval. RESULTS: An inverse correlation was observed between the increase in plasma levels of IFN-γ and normal auditory handicap (P = 0.015; rs = -0.280). The severe handicap group showed an increase in the averages I (P = 0.005; rs = 0.350) and II (P = 0.016; rs = 0.368) in the right ear and the light/moderate handicap group increased the means I (P = 0.027; rs = 0.350) and II (P = 0.046; rs = 0.310) of the left ear. A statistically significant association was found between the speech recognition threshold (SRT) test results of the right ear and the severe handicap group (P = 0.002; rs = 0.271). CONCLUSIONS: There was an association between the increase in plasma levels of IFN-γ and normal auditory handicap. Additionally, statistically significant associations were observed between the mild/moderate and severe handicap groups with the increase in hearing means and an increase in SRT associated with the severe handicap group.

Application of vascular photobiomodulation therapy in individuals with low back pain and its relationship with global methylation / Aplicação da terapia por fotobiomodulação vascular em indivíduos com lombalgia e sua relação com a metilação global

ABSTRACT BACKGROUND AND OBJECTIVES: Low back pain is among the most disabling conditions worldwide, and among the epigenetic factors, methylation in CpG islands of gene promoter regions can modulate gene expression, potentially correlating with the development of the disease and providing insights into the choice of treatment. The objective of this study was to assess the efficacy of therapy using modified ILIB related to DNA methylation processes in low back pain. Secondary objectives of this study included investigating pain intensity, gender, sociodemographic data, and physical-functional profile. METHODS: This prospective study was conducted in a municipality in the southern region of Brazil. The sample consisted of 30 participants of both genders, with an average age of 41.77 years. The following aspects were analyzed: anthropometric characteristics, global methylation using the ELISA method, pain level, physical activity level, functional disabilities, and hesitancy level related to work and physical activity-related activities. RESULTS: A statistically significant association was observed between methylation levels before and after treatment application for the experimental and placebo groups (p < 0.005), demonstrating a mean responsiveness between methylation and treatment (d = 0.5). However, there were no other statistically significant associations correlated with the other work variables. CONCLUSION: The results obtained in this study suggest the need for further research related to the identification of specific genes in methylation, as well as the standardization of dosimetry used for transcutaneous ILIB laser application in the radial artery.

RESUMO JUSTIFICATIVA E OBJETIVOS: A lombalgia está entre as condições mais incapacitantes no mundo e; dentre os fatores epigenéticos, a metilação em ilhas CpG de regiões promotoras de genes pode modular a expressão gênica permitindo uma possível correlação ao desenvolvimento da doença, como também pode trazer esclarecimentos a respeito do tratamento a ser escolhido. O objetivo deste estudo foi verificar a eficácia da terapia através do uso do ILIB modificado relacionada ao processo de metilação de DNA na lombalgia. Os objetivos secundários deste estudo foram a investigação da intensidade da dor, sexo, dados sociodemográficos e perfil físico-funcional. MÉTODOS: Este estudo, desenvolvido em um município da região sul do Brasil, caracteriza-se como prospectivo. A amostra deste estudo foi composta por 30 participantes, de ambos os sexos, com idade média de 41,77 anos. Foram analisados os seguintes aspectos: características antropométricas, metilação global através do método ELISA, nível de dor, nível de atividade física, incapacidades funcionais e nível de hesitação para realizar atividades relacionada ao trabalho e atividade física. RESULTADOS: Observou-se associação estatisticamente significativa entre os níveis de metilação antes e a após aplicação do tratamento para grupo experimental e placebo (p<0,005) demostrando uma média responsividade entre as variáveis metilação e tratamento (d=0,5). No entanto, não houve nenhuma outra associação estatística correlacionada as demais variáreis do trabalho. CONCLUSÃO: Os resultados obtidos neste estudo sugerem que há necessidade mais estudos relacionados a identificação de genes específicos na metilação, além da necessidade de padronização de dosimetria utilizadas para aplicação do laser ILIB de forma transcutânea, em artéria radial.

Bilateral Idiopathic Carpal Tunnel Syndrome: Clinical-Functional Characterization and Efficacy of Two Combined Postoperative Physiotherapeutic Treatments.

OBJECTIVE: To evaluate the efficacy of combined association instrument myofascial mobilization (IASTM) and stretching in patients with idiopathic bilateral carpal tunnel syndrome (CTS) operated on one hand and to analyze the response of the operated (OH) and non-operated (NH) hand according to the sequence of therapies. Research on these parameters has not yet been found in the literature. METHODS: Randomized controlled crossover study with 43 participants using the objective and subjective outcome variables. Patients were randomly assigned to two groups: starting with stretching followed by IASTM and starting with IASTM followed by stretching. Then patients underwent surgery on the hand with more severe involvement and physical therapy rehabilitation was started 30 days after for a period of 4 weeks. After the 1-week interval the participants who started with stretching were referred to IASTM and vice versa, following the same previous patterns. The outpatient reassessments took place at 3 to 6 months. Crossover ANOVA and effect sizes were used as analysis methods. RESULTS: Time was the most significant outcome for all variables both during therapies and at 6-month follow-up. Regarding response to the combined therapies between OH and NH, there were differences for both OH and NH, with the greatest impact on NH for the palmar grip and VAS variables. The treatment sequences were significant for pain on the NH and mental SF-12, suggesting that starting with IASTM followed by stretching had a superior outcome for these outcomes. CONCLUSION: The combination of IASTM with stretching, used in the postoperative period of bilateral idiopathic CTS, proved to be supplementary, with significant results and large effect sizes for most of the outcomes assessed, both during the time of application of the therapies and in the 6-month follow-up for both hands, and may constitute a viable therapeutic alternative for this population.

Does photobiomodulation improve muscle performance and recovery? a systematic review / ¿la fotobiomodulación mejora el desempeño y la recuperación muscular? una revisión sistemática / A fotobiomodulação melhora o desempenho e a recuperação muscular? uma revisão sistemática

ABSTRACT Photobiomodulation (PBM) appears to limit exercise-induced muscle damage, improve biochemical and functional recovery, and reduce inflammation and oxidative stress. This systematic review aimed to evaluate the effectiveness of photobiomodulation (PBM) in skeletal muscle recovery after exercise, addressing the different types of lasers and parameters used. Randomized clinical trials (RCTs) comparing the effects of PBM were included. The primary outcome evaluated was performance, and the secondary was inflammatory marker expression. The searches were conducted in March 2021. Fifteen RCTs that met the inclusion criteria were included. There was significant variability regarding the doses and wavelengths used, as well as in the types of lasers. However, in most studies, PBM promoted improvement of maximum voluntary contraction, better oxygen consumption, increased time to achieve exhaustion and fatigue, and decreased creatine kinase (CK), oxidative stress, and fatigue markers, mainly when used before exercise. Photobiomodulation applied before exercise, regardless of variations in doses and wavelengths, improves muscle performance and decreases levels of inflammation and fatigue markers. Evidence level II; Systematic review of level II studies.

RESUMEN La fotobiomodulación (PBM) parece aliviar el daño muscular inducido por el ejercicio, mejorando la recuperación bioquímica y funcional y reduciendo la inflamación y el estrés oxidativo. Esta revisión sistemática tuvo como objetivo evaluar la eficacia de la fotobiomodulación (PBM) en la recuperación del músculo esquelético después del ejercicio, abordando los diferentes tipos de láseres y parámetros utilizados. Se incluyeron ensayos clínicos aleatorizados (ECA) que compararon los efectos de la PBM. El resultado primario evaluado fue el desempeño y el secundario fue la expresión de marcadores inflamatorios. Se analizaron los estudios publicados hasta marzo de 2021. Resultados: Se incluyeron quince ensayos clínicos aleatorizados que cumplían los criterios de inclusión. Hubo una importante variabilidad en cuanto a las dosis y longitudes de onda utilizadas, así como al tipo de láser. Sin embargo, en la mayoría de los estudios, la PBM promovió una mejor contracción voluntaria máxima, un mejor consumo de oxígeno, un mayor tiempo para alcanzar el agotamiento y la fatiga, y una disminución de los niveles de creatina quinasa (CK), del estrés oxidativo y de los marcadores de fatiga, especialmente cuando se utiliza antes del ejercicio. La fotobiomodulación aplicada antes del ejercicio, a pesar de presentar gran variabilidad de dosis y longitudes de onda, ha demostrado mejorar el desempeño muscular y disminuir los niveles de marcadores inflamatorios y de fatiga. Nivel de evidencia II; Revisión sistemática de estudios de nivel II.

Different kinesio taping tensions present similar benefits for postural control, dynamic balance, agility and instability sensation in individuals with chronic ankle instability: randomized clinical trial / Diferentes tensões de kinesio taping apresentam benefícios semelhantes para controle postural, equilíbrio dinâmico, agilidade e sensação de instabilidade em indivíduos com instabilidade crônica do tornozelo: ensaio clínico randomizado

Abstract Ankle sprain is the most common injury in the lower limbs of physically active individuals, and one of its complications is chronic ankle instability (CAI), for which Kinesio Taping (KT) can be an alternative treatment. The aim of this study was to compare two treatment protocols with KT at different tensions on postural control, dynamic balance, agility and instability in individuals with chronic ankle instability. This is a randomized clinical trial in which postural control was evaluated through the force platform, agility by the side Hop Test, dynamic balance by the modified Star Excursion balance Test, and application of the Cumberland Ankle Tool Instability and Foot and Ankle Outcome Score to assess self-reported instability and functional instability. An initial assessment was conducted, followed by 5 weeks of intervention with weekly applications of KT, and one week after the completion of the intervention, a reassessment was performed. 21 participants were distributed to the group KT with tension (KTT: n=11) and the group KT without tension (KTWT: n=10). KT improves postural control (anteroposterior velocity: p=0.006 and mediolateral: p<0.001; anteroposterior frequency: p<0.001 and mediolateral: p=0.043 of the area of the center of pressure), dynamic balance (p< 0.001), agility (p=0.001) and feeling of instability in individuals with ICT (p=0.001) for both groups. Only one variable, sports category of the FAOS-FOOT questionnaire showed significant change (p=0.008). KT, with or without tension, is able to improve postural control, balanced balance, postural control, and feelings of instability in young adults with ICT.

Resumo A entorse de tornozelo, uma lesão comum em indivíduos fisicamente ativos, frequentemente resulta em uma complicação chamada instabilidade crônica do tornozelo (ICT). A Kinesio Taping (KT) pode ser uma alternativa de tratamento para essa condição. O objetivo deste estudo foi comparar dois protocolos de tratamento com KT em diferentes tensões no controle postural, equilíbrio dinâmico, agilidade e instabilidade em indivíduos com instabilidade crônica do tornozelo. Trata-se de um ensaio clínico randomizado no qual o controle postural foi avaliado por meio da plataforma de força, a agilidade pelo side Hop Test, o equilíbrio dinâmico pelo Star Excursion balance Test modificado e para avaliar instabilidade funcional e autorrelatada aplicou-se o Foot and Ankle Outcome Score e o Cumberland Ankle Tool Instability. Foi realizada uma avaliação inicial, seguida de 5 semanas de intervenção com aplicações semanais de KT, e uma semana após o término da intervenção, foi realizada uma reavaliação. 21 participantes foram distribuídos para o grupo KT com tensão (KTT: n=11) e o grupo KT sem tensão (KTWT: n=10). KT melhora o controle postural (velocidade ântero-posterior: p=0,006 e médio-lateral: p<0,001; frequência anteroposterior: p<0,001 e médio-lateral: p=0,043 da área do centro de pressão), equilíbrio dinâmico (p<0,001), agilidade (p=0,001) e sensação de instabilidade em indivíduos com ICT (p=0,001) para ambos os grupos. Apenas uma variável, categoria esportiva, do questionário FAOS-FOOT apresentou alteração significativa (p=0,008). O KT, com ou sem tensão, é capaz de melhorar o controle postural, o equilíbrio equilibrado, o controle postural e a sensação de instabilidade em adultos jovens com ICT.

ABSTRACT Purpose: to analyze the impact of neck pain, neck mobility, and body mass index on teachers' postural control. Methods: a cross-sectional study with 54 state public school teachers, 68.5% (n = 37) being females, with a mean age of 46.5 ± 9.3 years. Data were collected with the following instruments: Craniocervical Dysfunction Index (Brazilian version), force platform in bipedal and semi-tandem stance, visual analog scale, cervical mobility index, and body mass index. Data were analyzed with nonparametric statistics and multiple linear regression; the significance level was set at p<0.05, with 95% confidence intervals. Results: teachers with neck pain and severely impaired neck mobility had greater postural control changes in the semi-tandem stance. In the bipedal stance, those with mild mobility changes and neck pain had a smaller total displacement. Obese teachers had a smaller movement amplitude in the anteroposterior and mediolateral directions. Conclusion: teachers presented with neck pain and severely impaired neck mobility had a worse postural control. Obese teachers had a smaller total amplitude in both movement directions.

Na posição bipodal, aqueles com leve alteração da mobilidade e dor cervical apresentaram menor deslocamento total, assim como professores obesos demostraram menor amplitude de movimento nas direções anteroposterior e médio-lateral. Conclusão: os professores com cervicalgia e comprometimento severo da mobilidade cervical tiveram pior controle postural. Já os obesos apresentaram menor amplitude total em ambas as direções do movimento.

Progressive tension protocol for muscle strength with Kinesio tape in runners - double-blind randomized clinical trial / Protocolo de tensão progressiva para força muscular com Kinesio tape em corredores - ensaio clínico randomizado duplo-cego

Abstract Introduction Kinesio tape (KT), although frequently used in sports, is still a matter of debate, and the results of studies that evaluated its effects on muscle strength (MS) in athletes are still inconclusive and contradictory. Objective To evaluate the effect of a progressive KT tension protocol on knee MS in runners over an eight-week intervention. Methods Clinical trial involving 49 runners of both sexes randomized into two groups: KT (KT with progressive tension protocol) and placebo (KT without tension). The MS of knee flexors and extensors was evaluated by isokinetic dynamometer (60º/s and 90º/s) at four moments: (1) without KT; (2) with KT and without tension; (3) without KT (after 8 weeks after of intervention); (4) with KT and with tension (after 8 weeks after of intervention). Inter- and intra-group comparisons were made. The significance level adopted was 95% (p < 0.05). Results There were no significant differences in MS between the groups at any of the evaluated moments. There was a statistically significant difference in MS (60º/s) in both groups (KT and placebo) when comparing moments 4 and 2 for knee flexors, and in the placebo group between moments 4 and 2 and moments 4 and 3 for knee extensors. Conclusion The progressive tension protocol of KT was not able to intervene in the SM gain of knee flexors and extensors of runners in inter and intragroup comparisons.

Resumo Introdução A Kinesio tape (KT), apesar de muito utilizada na prática esportiva, ainda é motivo de debate e os resultados de estudos que avaliaram seus efeitos na força muscular (FM) em atletas ainda são inconclusivos e contraditórios. Objetivo Avaliar o efeito de um protocolo de tensão progressiva KT na FM do joelho em corredores ao longo de uma intervenção de oito semanas. Métodos Ensaio clínico envolvendo 49 corredores de ambos os sexos randomizados em dois grupos: KT (KT com protocolo de tensão progressiva) e placebo (KT sem tensão). A FM dos flexores e extensores do joelho foi avaliada por dinamômetro isocinético (60º/s e 90º/s) em quatro momentos: (1) sem KT; (2) com KT e sem tensão; (3) sem KT (após 8 semanas); (4) com KT e com tensão (pós-protocolo 8 semanas). Comparações inter e intragrupos foram feitas. O nível de significância adotado foi de 95% (p < 0,05). Resultados Não houve diferenças signi-ficativas na FM entre os grupos em nenhum dos momentos avaliados. Houve diferença estatisticamente significante na FM (60º/s) em ambos os grupos (KT e placebo, quando comparados os momentos 4 e 2 para flexores de joelho, e no grupo placebo entre os momentos 4 e 2 e os momentos 4 e 3 para extensores de joelho. Conclusão O protocolo de tensão progressiva de KT não foi capaz de intervir no ganho de FM de flexores e extensores de joelho de corredores em comparações inter e intragrupos.

Effects of photobiomodulation and deep water running in patients with chronic non-specific low back pain: a randomized controlled trial.

Photobiomodulation therapy (PBM) is often used to treat musculoskeletal disorders such as chronic non-specific low back pain (NSCLBP) as it can have positive effects on biomarkers-creatine kinase (CK) and serum cortisol levels-related to stress caused by physical exercise, such as deep water running (DWR) or by pain. The aim of this study was to evaluate the effects of the combination of PBM and aquatic exercise (DWR) on the intensity of pain, disability, 6-min walk test adapted (6WTA), and on cortisol and creatine kinase (CK) levels in a population with NSCLBP. The participants were allocated into three groups: TGPBM (Photobiomodulation and Training Group), TGPLA (Placebo Photobiomodulation and Training Group), and the GPBM (Photobiomodulation Group). Information regarding anthropometric data, blood pressure, and heart rate were collected, and the questionnaires were applied: IPAQ-Short Form, Oswestry Disability Index, and the Visual Analog Scale for Pain. The submaximal exercise test (6WTA) was performed. Blood was collected for analysis of cortisol and CK levels. The training sessions were performed twice a week, for 4 weeks. In the intragroup comparisons, there were statistically significant changes in the TGPBM and GPBM groups in the outcomes pain intensity, disability (reductions in both groups), and in cortisol (increased in the TGPBM and reduced in the GPBM); in the TGPLA group, there was a statistically significant reduction only in the outcome of pain intensity. In the intergroup comparison, in the comparison between TGPBM and TGPLA, there was a statistically significant difference in the level of cortisol, as well as in the comparison between TGPBM and GPBM, in which there was a statistically significant difference for this same outcome (cortisol) and for the 6WTA outcome. The effects of the combination of PBM and aquatic exercise have positive effects on reducing pain intensity, disability, and cortisol levels, but its effects on other variables (6WTA and CK) are too small to be considered significant. Trial registration number: NCT03465228-April 3, 2019; retrospectively registered (ClinicalTrials.gov).

Systemic photobiomodulation in nursing professionals with chronic low back pain.

Introduction: Chronic low back pain is a frequent complaint at health care services, leading to absenteeism and high treatment costs. Photobiomodulation is a cost-effective, non-pharmacological treatment option. Objectives: To assess the cost of systemic photobiomodulation in nursing professionals with chronic low back pain. Methods: This is a cross-sectional analytical study that analyzed the absorption costing of systemic photobiomodulation in chronic low back pain and was performed in a large university hospital with 20 nursing professionals. Ten systemic photobiomodulation sessions were performed using MM Optics® laser equipment at 660 nm wavelength, 100 mW power, 33 J/cm2 dose, for 30 minutes on the left radial artery. Direct (supplies and direct labor costs) and indirect costs (equipment and infrastructure) were measured. Results: The mean cost of photobiomodulation was R$ 25.30 ± 0.50, and the mean duration was 1,890 seconds ± 55.0. Regarding the first, fifth, and tenth sessions, labor costs were the highest (66%), followed by infrastructure (22%), supplies (9%), and the laser equipment, which presented the lowest cost (2.8%). Conclusions: Systemic photobiomodulation was shown to be a low-cost therapy when compared to other therapies. The laser equipment represented the lowest cost in the general composition.

Effect of Photo Biomodulation on Muscle Repair: a Literature Review / Efeito da Fotobiomodulação Sobre o Reparo Muscular: uma Revisão de Literatura

Abstract Muscle injuries are frequent, both in the practice of exercises and in the work environment, and after the injury, healing begins. The inflammatory phase of muscle healing is accompanied by an increase in the production of reactive oxygen species (ROS), and a reduction in the antioxidant activity of defense enzymes. This imbalance between both can generate oxidative stress, which can cause oxidative damage by directly affecting vital cellular constituents, such as lipids, proteins and DNA, in addition to interfering negatively in the muscle cells differentiation . Therefore, substances or therapies that stimulate antioxidant repair and defense are crucial to keep the levels of free radical production low, and to minimize factors that delay or prevent tissue recovery, among these therapies photo biomodulation has stood out. The objective of this literature review is to clarify the FBM effect on oxidative stress and muscle repair. Therefore, a search was carried out in the databases of Pubmed, Scielo, Lilacs and PEDro, using the keywords "Photo biomodulation", "low power laser", "muscle repair", "oxidative stress", and in English were "Photo biomodulation", "low level laser therapy", "muscle repair" and "oxidative stress". The texts that addressed the research topic, published between 2000 and 2020, were chosen. After analyzing the articles, it was possible to observe that photo biomodulation, despite presenting a great variety of parameters, moment of application and irradiation protocol found in the literature, shows beneficial results in the repair muscle and in the reduction of oxidative stress and fatigue markers.

Resumo Lesões musculares são frequentes, tanto na prática de exercícios como no ambiente de trabalho, sendo que após a lesão, inicia a cicatrização. A fase inflamatória da cicatrização muscular é acompanhada do aumento da produção de espécies reativas de oxigênio (ERO) e uma redução da atividade antioxidante das enzimas de defesa. Este desequilíbrio entre ambos pode gerar o estresse oxidativo, que leva a danos e atingi diretamente constituintes celulares vitais, como lipídios, proteínas e DNA, além de interferir negativamente na diferenciação das células musculares. Portanto, substâncias ou terapias que estimulem a reparação e a defesa antioxidante são cruciais para manter os níveis de produção de radicais livres baixos, e minimizar os fatores que atrasam ou impedem a recuperação do tecido, dentre estas terapias a fotobiomodulação tem se destacado. O objetivo da presente revisão de literatura é esclarecer o efeito da FBM sobre o estresse oxidativo e o reparo muscular. Sendo assim, realizou-se uma pesquisa nas bases de dados da Pubmed, Scielo, Lilacs e PEDro, utilizando as palavras-chave "Fotobiomodulação", "laser de baixa potência", "reparo muscular", "estresse oxidativo", e em inglês foram "photobiomodulation", "low level laser therapy", "muscle repair" e "oxidative stress". Foram escolhidos os textos que abordavam o tema da pesquisa, publicados entre 2000 e 2020. Analisando os artigos foi possível observar que a fotobiomodulação apesar de apresentar grande variedade de parâmetros, momento de aplicação e protocolo de irradiação encontrados na literatura, mostra resultados benéficos no reparo muscular e na diminuição de marcadores do estresse oxidativo e fadiga.

Evaluation of the effects of different applications of kinesio taping on postural control in healthy women.

It has been demonstrated that Kinesio Tape (KT) application has immediate positive effects on balance in healthy individuals, but its mid-term effects have not yet been investigated. OBJECTIVE: Evaluate the effects of KT on postural control in young women, using four strategies. METHODS: Forty-eight healthy women aged 18-35 years old were randomly assigned to four groups with different elastic bandages (G1: ankle; G2: hamstrings; G3: lumbar; G4: different taping applications) and their postural control was evaluated using stabilographic parameters obtained on a force platform during right and left unipodal (UNP-R and UNP-L) and semi-tamdem tests at pre-intervention (PRE), immediately after (IME), and 24 and 48 h after the application of bandages. RESULTS: G1 showed a significantly lower velocity in the antero-posterior direction for the PRE compared to the IME period (p = 0.0204) in the UNP-R task, and the same was observed in the medio-lateral velocity when comparing the results for PRE with IME (p = 0.0340 and p = 0.0244) in the UNP-L task. Regarding the frequency, G2 had a significantly lower mean for the PRE, compared to IME (p < 0.001) in the UNP-R in antero-posterior direction, and in medio-lateral direction in the UNP-R (p = 0.003) and in the UNP-L task (p = 0.020). CONCLUSIONS: The use of KT changed postural control, mainly considering the velocity and frequency of COP oscillations, and especially immediately after its application.

Low- level laser: cost of therapy fornipple trauma / Laser de baixa intensidade: custo da terapia no trauma mamilar

Abstract Objectives: to measure the micro-cost of local laser therapy (LL) and transcutaneous laser therapy application by Irradiation Laser Intravascular of Blood (ILIB) to treat nipple trauma and compare the most effective and efficient alternative treatment. Methods: a cross-sectional analytical and quantitative study with analysis on the micro absorption cost, implemented as a clipping, from a randomized clinical trial that used two types of laser therapy to treat nipple trauma due to breastfeeding. The sample consisted of 101 nipple lesions. Patients were randomized into three groups (Control - CG, Local Laser -LLG and ILIB-ILIBG). Materials used, direct labor (DL) and laser equipment were predictors of costs. The delta calculation (effect size) was the indicator for measuring effectiveness and efficiency. Results: after three sessions, the average final cost was R$ 40.04for CG, R$ 53.55for LLG and R$ 67.29for ILIBG. After three sessions of treatment, ILIBG showed a great reduction in the lesion area, but with a higher cost (p<0.05). Conclusions: ILIBG had a better effect on healing the nipple trauma when compared to CG and LLG, even though it is more expensive, it suggests a positive cost-benefit and the most effective and efficient alternative treatment.

Dysphonia, arterial hypertension, diabetes mellitus, thyroid diseases, and noise complaints as probable factors associated with hearing loss among teachers / Disfonia, hipertensão arterial, diabetes mellitus, doenças da tireoide e queixas de ruído como prováveis fatores associados a perda auditiva em professores

ABSTRACT Objective: to verify a possible association between hearing loss and dysphonia, arterial hypertension, diabetes mellitus, thyroid diseases, and noise complaints. Methods: a cross-sectional study involving 60 teachers, mean age 47.05 years. Pure-tone threshold audiometry was used to assess hearing, the voice questionnaire and voice acoustic evaluation were used for voice perception and quality, and the standardized questionnaire verified noise complaint and comorbidities. The statistical analysis was conducted with Mann-Whitney and Fisher's exact tests and multivariate linear regression. Results: there was a significant association between hearing loss and diabetes mellitus, hypertension, and thyroid disease (both p <0.0001), but there was no association between noise complaints and hearing loss in this population. The regression showed that dysphonia (p = 0.0311) and diabetes mellitus (p = 0.0302) are independent risk factors for hearing loss. A correlation was found between hearing loss and voice characteristics: roughness, breathiness, tension, and resonance. Conclusion: this study showed that hypertension and thyroid diseases are factors associated with hearing loss. In addition, dysphonia and diabetes mellitus are independent factors associated with hearing loss in teachers. These results show the need for policies aimed at promoting teachers' health.

RESUMO Objetivo: verificar possível associação da perda auditiva com disfonia, hipertensão arterial (HA), diabetes mellitus (DM), doenças da tireoide e queixas de ruído. Métodos: estudo transversal envolvendo 60 professores, média de idade de 47,05 anos. Foi avaliada a audição por meio da Audiometria tonal limiar, a percepção e qualidade vocal com o questionário vocal e a avaliação vocal acústica, enquanto a queixa de ruído e as comorbidades envolvidas foram investigadas com o questionário padronizado. A análise estatística utilizou os testes Ex-act de Mann Whitney, Fisher e regressão linear multivariada. Resultados: houve associação significante entre perda auditiva e DM, HA e doenças da tireoide (ambas p <0,0001), mas não foi encontrada associação entre queixa de ruído e perda auditiva nesta população. A regressão mostrou que as variáveis disfonia (p = 0,0311) e DM (p = 0,0302) são fatores de risco independentes para perda auditiva. Houve correlação entre perda auditiva e as características vocais rugosidade, soprosidade, tensão e ressonância. Conclusão: este estudo demostrou que HA e doenças da tireoide são fatores associados a perda auditiva, além disso a disfonia e DM se constituem em fatores associados independentes para a perda auditiva em professores. Estes resultados mostram a necessidade de políticas direcionadas a promoção da saúde do professor.

Kinesio taping use to reduce pain and edema after third molar extraction surgery: A randomized controlled split-mouth study.

OBJECTIVE: Evaluating Kinesio Taping (KT) use to reduce pain and edema in individuals subjected to surgical extraction of impacted mandibular third molars. MATERIALS AND METHODS: Thirteen individuals (5 men and 8 women, mean age: 23.25 years) were subjected to mutual extraction of two mandibular third molars based on the same surgical protocol and pharmacological approach. All individuals were subjected to kinesio taping application on one side of patients' face (test group - KT), in the immediate postoperative period. The other side of the face was not subjected to KT application, and it was used as control (No KT). An examiner assessed individuals' pain and edema based on the visual analog scale (VAS) and on the Todorovic-Markovic method, respectively, at the preoperative, immediate postoperative, and second and fifth postoperative days. Statistical analysis was based on the Scheirer-Ray-Hare test. RESULTS: Edema (48 h and 120 h after surgery) and pain intensity (24 h, 48 h and 120 h after surgery) were lower on the KT side (p < 0.05). Moreover, edema and pain intensity fully reduced on the KT side 120 h after surgery (p < 0.05). CONCLUSION: Kinesio taping adopted in the current study was effective in reducing edema and postoperative pain in patients subjected to oral surgery. CLINICAL RELEVANCE: KT enables patients to experience a more comfortable postoperative period and helps improving their quality of life.

Effects of low level laser therapy in cancer cells-a systematic review of the literature.

The aim of the present study was to conduct a systematic review regarding the use of photobiomodulation (PBM) therapy in tumoral cells, addressing the different types of lasers and parameters used. An electronic search was performed in PubMed/MEDLINE, Cochrane Library, and EMBASE databases. The inclusion criteria were being an in vitro study, with tumoral cells, and have at least one group of treatment with low-power laser and a control group (without treatment). Were excluded studies that used only non-carcinogenic cells, in vivo studies, studies that used high-power laser or the association with photosensitizers. The primary outcome evaluated was the cellular viability, and the secondary outcomes were the apoptosis rate and gene and inflammatory mediators' expression. Nineteen studies were identified among the lists of citations of studies that met the exclusion/inclusion criteria. There is a wide divergence regarding the wavelengths and doses used, as well as the type of laser, and each variation leads to different results, with some studies showing an increase in cell proliferation, while other studies showed a decrease. It is possible to suggest that PBM can be used in cancerous lesions in order to decrease the proliferation of these cells depending on the parameters used; however, the lack of standardization of laser irradiation protocols for in vitro investigations does not allow the establishment of ideal parameters for this purpose. Therefore, PBM should be used with caution in cancer patients until more studies are performed.

Effects of beta-alanine supplementation on muscle function during recovery from resistance exercise in young adults.

ß-Alanine supplementation has been shown to increase muscle carnosine levels and exercise performance. However, its effects on muscle recovery from resistance exercise (RE) remains unknown. The purpose of this study was to investigate the effects of ß-alanine supplementation on muscle function during recovery from a single session of high-intensity RE. Twenty-four untrained young adults (22.1 ± 4.6 years old) were assigned to one of two groups (N = 12 per group): a placebo-supplement group (4.8 g/day) or an ß-alanine-supplement group (4.8 g/day). The groups completed a single session of high-intensity RE after 28 days of supplementation and were then evaluated for muscle function on the three subsequent days (at 24, 48, and 72 h postexercise) to assess the time course of muscle recovery. The following indicators of muscle recovery were assessed: number of repetitions until failure, rating of perceived exertion, muscle soreness, and blood levels of creatine kinase (CK). Number of repetitions until failure increased from 24 to 48 h and 72 h of recovery (time P < 0.01), with no difference between groups. There was a significant increase in the rating of perceived exertion among the sets during the RE session (time P < 0.01), with no difference between the groups. No difference was observed over time and between groups in rating of perceived exertion in the functional tests during recovery period. Blood CK levels and muscle soreness increased at 24 h postexercise and then progressively declined at 48 and 72 h postexercise, respectively (time P < 0.05), with no difference between groups. In conclusion, our data indicate that ß-alanine supplementation does not improve muscle recovery following a high-intensity RE session in untrained young adults.
