Introducción: El diagnóstico de lesiones musculares es un desafío en contextos de poco acceso a los servicios de la salud. La integración de técnicas de movimiento puede favorecer y mejorar integralmente el análisis de estas lesiones. Objetivo: Desarrollar un enfoque de procesamiento óptico y físico para el análisis de lesiones musculares en las extremidades superiores. Métodos: Se realizó un estudio observacional, exploratorio, en 7 adultos peruanos. Se realizaron maniobras para evaluar segmentos específicos del miembro superior (método convencional) y el software Skillspector para recopilar y analizar datos biomecánicos por procesamiento óptico y físico. Se compararon los 2 métodos, mediante 5 parámetros de la metodología Six Sigma. Resultados: El 71,4 % de los participantes presentaba lesiones en el antebrazo y el 42,9 % mostró un cambio significativo en la variabilidad biomecánica. El método convencional tuvo una Sigma menor (3,45) que el alternativo (5,55). A pesar de sus ventajas, la complejidad en la manipulación de datos y la susceptibilidad de variables fueron limitaciones del método alternativo durante el modelado digital del paciente. Conclusiones: El procesamiento óptico y físico con Skillspector tiene alta eficacia para analizar lesiones musculares, superior al método de maniobras biomecánicas.

There is a dearth of biomarkers in Idiopathic Inflammatory Myopathies (IIM) to recognize ongoing muscle inflammation and distinguish damage from activity. Since IIM is an autoantibody-mediated disease with tertiary lymphoid organogenesis reported in the diseased muscles, we aimed to study the peripheral blood T helper (Th) subset profiling as a plausible reflection of ongoing muscle inflammation. Fifty-six patients of IIM were compared with 21 healthy controls (HC) and 18 patients with sarcoidosis. Th1, Th17, Th17.1, and Treg cells were identified after stimulation assays (BD Biosciences). Myositis autoantibodies were tested by line immunoassay (Euroimmune, Germany). All Th subsets were elevated in IIM as compared with HC. As compared to HC, PM had elevated Th1 and Treg while Th17 and Th17.1 populations were higher in OM. Patients with sarcoidosis had higher Th1 and Treg but lower Th17 population as compared to IIM {Th1(69.1% vs 49.65%, p < 0.0001), {Treg (12.05% vs 6.2%, p < 0.0001), {Th17 (2.49% vs 4.4%, p < 0.0001)}. Similar results were obtained when sarcoidosis ILD was compared with IIM ILD with a higher Th1 and Treg population but lower Th17 population in the former. No difference in T cell profile was observed after stratification for MSA positivity, type of MSA, clinical features of IIM and disease activity. Th subsets in IIM are distinct from sarcoidosis and HC with a TH17 predominant paradigm, creating a case of exploring Th17 pathway and IL-17 blockers for the treatment of IIM. However, cell profiling cannot distinguish active from inactive disease limiting its predictive potential as a biomarker of activity in IIM. [ABSTRACT FROM AUTHOR]

Antecedentes: La exposición ósea puede ser consecuencia de fracturas traumáticas abiertas o cerradas con complicaciones, así como secundarias a procesos infecciosos. La cobertura del miembro inferior con defecto cutáneo se basa en la preservación de la perfusión sanguínea y nerviosa para favorecer la consolidación ósea y así el salvamento del miembro. Descripción de los casos: Se describe la reconstrucción con colgajo muscular rotacional pediculado de sóleo y/o gastrocnemio en 16 pacientes con complicaciones asociadas a fracturas expuestas en miembros inferiores con defectos de partes blandas y pérdida de cobertura cutánea, realizados en el Servicio de Ortopedia y Traumatología del Hospital Escuela (HE) durante el período 2012-2015. Se realizó colocación de colgajo con sóleo en 50.0% (8/16) y gastrocnemio en 50.0% (8/16). El éxito terapéutico calificado quirúrgica y funcionalmente fue del 87.5% (14/16). Conclusión: Con la técnica de reconstrucción realizada a estos pacientes se logró disminuir la frecuencia de complicaciones y por consiguiente evitar la amputación de la extremidad afectada.

Introducción. Las diferencias en la activación muscular de las porciones lateral y medial del cuádriceps durante la ejecución del salto, pueden convertirse en un factor de riesgo neuromuscular al aumentar el valgo dinámico de rodilla y, en consecuencia, el riesgo de lesión del ligamento cruzado anterior de la rodilla. Objetivo. Determinar la diferencia en la activación de los vastos lateral y medial del cuádriceps mediante electromiografía de superficie durante el salto con una sola pierna en los planos sagital y frontal en mujeres deportistas. Materiales y métodos. Se hizo un estudio cuantitativo de corte transversal con la participación de 64 mujeres deportistas a quienes se les tomaron las medidas antropométricas. Se hicieron pruebas de salto vertical y lateral con una sola pierna evaluados mediante la activación electromiográfica de los vastos medial y lateral, y la valoración de la flexibilidad de la banda iliotibial. Resultados. Se encontró una relación estadísticamente significativa (p≤0,05) entre el índice de masa corporal, el porcentaje de grasa y la potencia en los saltos verticales con una sola pierna. Se encontró, asimismo, significación estadística (p≤0,05) por una mayor activación del vasto lateral en el salto vertical con la pierna derecha y en el salto lateral con las dos piernas. Conclusión. Las deportistas presentaron diferencias en la activación de los cuádriceps, siendo mayor la activación del vasto lateral en la mayoría de los saltos con una sola pierna tanto en el plano sagital como en el frontal, lo cual puede contribuir a un aumento del riesgo de lesión de rodilla en la práctica deportiva.

Background: The scarce studies regarding the non-professional caregivers health have focused more on the repercussions of care on their mental health than on the study of musculoskeletal injuries (MSI), despite the fact that care can cause the development of MSI, due to the personal characteristics of the caregiver or the environment that surrounds them. Objective: To identify the factors associated with MSI in elderly caregivers in a second-level hospital in Mexico and to know its prevalence. Material and methods: Analytical observational study; a questionnaire was administered to 283 elderly caregivers and their dependents. The survey included 62 variables related to environmental factors, factors inherent to care, and personal factors, in addition to the site of MSI; statistical analysis was descriptive and analytical (multivariate model). Results: Prevalence of MSI in older adult caregivers was 34.6%. Main factors associated were being female, having some comorbidity, duration of care greater than 13 hours a day for more than 13 months, a physical area reduced to provide care and social isolation. These factors increased between 1.9 and 12 the risk of suffering an MSI. Musculoskeletal injuries occurred mainly at the lumbar level of the spine. Conclusions: This is the first report in Mexico that identifies the prevalence of MSI in older adult caregivers and the factors associated with them. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effects of photobiomodulation therapy in redox status, angiogenesis marker – vascular endothelial growth factor – and in the functional recovery in denervated muscle. Methods: A total of 32 female Wistar rats underwent a crush injury and were randomly divided into four groups: Light Emitting Diode Group 2 and Control Group 2 (muscle collected 2 days after injury), and Light Emitting Diode Group 21 and Control Group 21 (muscle collected 21 days afterinjury). Light Emitting Diode Group 2 and Light Emitting Diode Group 21 received two and ten light emitting diode applications (630±20nm, 9J/cm2, 300mW), respectively, and the Control Group 2 and Control Group 21 did not receive any treatment. The function was evaluated by grasping test at four moments (pre-injury, 2, 10 and 21 post-injury days). The flexor digitorum muscle was collected for analysis of immunolocalization of vascular endothelial growth factor and redox parameters. Results: Functional improvement was observed at the second and tenth post-injury day in treated groups compared to control (p<0.005). The muscle tissue of treated groups presented higher immunohistochemical expression of vascular endothelial growth factor. Photobiomodulation therapy decreased the oxidative damage to lipid in Light Emitting Diode Group 2 compared to Control Group 2 (p=0.023) in the denervated muscle. Conclusion: Photobiomodulation therapy accelerated the functional recovery, increased angiogenesis and reduced lipid peroxidation in the denervated muscle at 2 days after injury.

Introduction: Differences in the lateral and medial portions from quiadriceps muscular activation during the jump execution can become a neuromuscular risk factor raising knee dynamic valgus, raising the risk for ACL injury. Objective: To determine the lateral and medial vastus difference activation using surface electromyography during single-leg jump in the sagittal and frontal plane in women athletes. Materials and methods: quantitative, cross-sectional study. A 64 female athletes study participation, testing antropometric mesures, vertical and lateral single-leg jump tests with the evaluation of vastus medialis and lateral electromyographic activation during the tests, and iliotibial band flexibility assessment. Results: it was found statistically significant relationship (p≤0.05) between body mass index, fat percentage and vertical single-leg jumps power. Statistical significance was found (p≤0.05), with greater activation of the lateral vastus in the right lower limb vertical jump and in the lateral jump in both lower limbs. Conclusion: Athletes presented differences in quadriceps activation, being higher lateral vastus activation in most of unipodal jumps, both in the sagittal and frontal plane; this may increase the risk for suffering knee injuries in sport practice.

Introduction: Infrared thermography (IT) is an imaging technique that detects heat radiation emitted by an object and collects it to convert it into temperature values. In sports, it is used to identify damage to musculoskeletal structures based on the variation of body temperature in affected anatomical areas. Objective: To assess the effectiveness of IT as a tool to detect damaged muscles after running a marathon. Materials and methods: 17 runners were assessed before and after running a marathon (42.196 km) using thermographic equipment. Results: Statistically significant temperature differences were found before and after running a marathon. There was a difference between previous and posterior measurement >1°C in the vastus lateralis, vastus medialis, rectus femoris and adductor of the dominant leg, which, based on clinical parameters, indicates damage in these muscles. Increases in temperature were heterogeneous among anatomical areas. Conclusions: IT is an effective tool for detecting damaged muscle areas in runners after participating in a marathon.

ABSTRACT Systematic studies involving technologies such as surface electromyography (sEMG) may provide important data that enable veterinarians to recognize musculoskeletal, ligamentous, and neurological alterations. The aim of this study was to describe the gait cycle phases and the timing of muscle activation in healthy Boxer dogs during gait by means of sEMG. The gait cycle of seven Boxer dogs was evaluated and sEMG was recorded from the biceps brachii, triceps brachii, brachiocephalic, rectus femoris, semitendinosus, semimembranosus, and superficial gluteal muscles of the right hemibody. Circular monopolar Ag/AgCl electrodes were attached to the mean point between the motor point and the muscle insertion. The electromyographic signals were collected by an active interface with 20-fold gain in a bipolar differential configuration using a 16-channel signal conditioner (EMG Systems Brasil), while the dogs walked on a treadmill at a speed of 2m/s. Pearson's correlation was used for the statistical analysis. A positive correlation was found between the rectus femoris and biceps brachii (r= 0.81); superficial gluteal and triceps brachii (r= 0.69); semitendinosus-semimembranosus and biceps brachii (r= 0.76); and rectus femoris and semitendinosus and semimembranosus muscle groups (r=0.99). The biceps brachii and brachiocephalic muscles work in tandem to position the thoracic limb during the gait cycle, while the semitendinosus-semimembranosus group flexes the knee and, simultaneously with the quadriceps that flexes the hip, prevents the contact of the pelvic limb with the ground during the swing phase. The body is propelled forward by the triceps brachii muscle, which extends the elbow and flexes the shoulder at the final contact, while the superficial gluteal muscle extends the hip.

ABSTRACT Scoliosis is characterized by three-dimensional changes of the spine and is estimated to be present in 4% of the population worldwide. The most common form is the adolescent idiopathic. The purpose of this study is to identify the major muscle abnormalities found in patients with adolescent idiopathic scoliosis through a literature review. We conducted an electronic search of the national databases PubMed, Lilacs, PEDro, and EMBASE using the keywords "scoliosis", "biomechanics", "exercise", "physical therapy specialty", "idiopathic", and "muscles", from January 2003 to April 2015. The most relevant articles in English, Portuguese and Spanish were selected by title and abstract. It was also performed a manual search of the references of the selected articles. From a total of 4,319 articles, 11 were selected. We conclude that individuals with AIS have changes in the paraspinal muscles, with a difference in activation between the concave and convex sides, suggesting an increase in EMG activity on the convex side, although there is still no consensus among the authors.

Resumo: Objetivou-se descrever os músculos do membro torácico da paca (Cuniculus paca Linnaeus, 1766), mediante dissecação anatômica dessa região. Foram utilizadas cinco Cuniculus paca adultas, machos e fêmeas, pesando entre cinco e 10kg do plantel de pacas do setor de Animais Silvestres da FCAV, Unesp, Jaboticabal/SP. Os animais foram fixados em formoldeído a 10% e conservados em solução salina a 30% para dissecação anatômica da musculatura do ombro, braço e antebraço, identificando-se a origem e inserção de cada músculo. Os resultados foram fotodocumentados e discutidos com base na literatura sobre animais domésticos, ratos e cobaias. Salvo algumas variâncias na origem e inserção de cada músculo e na fusão dos ventres de alguns grupos musculares, de forma geral, a musculatura do ombro, braço e antebraço da paca assemelha-se a dos animais domésticos e a de outros roedores.

Abstract Introduction: Evaluate the association between the thumb adductor muscle thickness and the patient's nutritional status, and propose cutoff points for muscle mass depletion in elderly patients with chronic kidney disease (CKD) under conservative treatment. Epidemiological and cross-sectional study, including patients with CKD stages 3 to 5, older than 60 years. Socioeconomic, clinical, physical activity and anthropometric data was obtained. TAMT was described and compared according to CKD stage, socioeconomic data, physical activity, nutritional status and correlated with age, glomerular filtration rate and anthropometric variables. Receiver Operating Characteristic (ROC) curves were produced, considering the lean tissue index classification as reference. The cut-off point was defined by the Youden index. Results: We evaluated 137 individuals. The TAMT was lower in malnourished and/or depleted muscle mass individuals; among males it was higher among those who practiced physical activities (p

Resumo: Objetivam-se descrever os músculos do membro pélvico da paca (Cuniculus paca Linnaeus, 1766), mediante dissecção anatômica dessa região. Foram utilizadas dez Cuniculus paca adultas, machos e fêmeas, pesando entre cinco e 10 kg do plantel de pacas do setor de Animais Silvestres da FCAV, Unesp, Jaboticabal/SP. Os animais foram fixados em formaldeído 10% e conservados em solução salina a 30% para dissecação anatômica da musculatura da pelve, coxa e perna, identificando-se a origem e inserção de cada músculo. Os resultados foram fotodocumentados e discutidos com base na literatura sobre animais domésticos, ratos e cobaias. Salvo algumas variâncias na origem e inserção de cada músculo e na fusão dos ventres de alguns grupos musculares, de forma geral, a musculatura da paca assemelha-se a dos animais domésticos e a de outros roedores.

RESUMO Objetivo: Verificar a relação do teste de espessura do músculo adutor do polegar com avaliação subjetiva global e correlacioná-lo a outros métodos antropométricos. Métodos: Estudo transversal observacional realizado em unidade de terapia intensiva de um hospital de cardiologia no Estado do Rio Grande do Sul. Os pacientes internados foram submetidos à avaliação subjetiva global, da espessura do músculo adutor do polegar em ambas as mãos e da circunferência da panturrilha da perna direita. Foram coletados parâmetros laboratoriais, tempo de internação, sinais vitais, dados e exames do prontuário eletrônico. Resultados: População composta de 83 pacientes, sendo 62% homens, com idade de 68,6 ± 12,5 anos. O motivo de internação mais frequente foi infarto agudo miocárdio (34,9%), e a patologia mais comum foi a hipertensão arterial sistólica (63,9%) seguida de diabetes mellitus (28,9%). Conforme a classificação da avaliação subjetiva global, 62,7% dos pacientes apresentaram-se sem risco nutricional, 20,5% moderadamente desnutridos e 16,9% gravemente desnutridos. As mulheres apresentaram maior risco nutricional, tanto pela avaliação subjetiva global quanto pela espessura do músculo adutor do polegar, que foi < 6,5mm (54,8%; p = 0,001). A patologia com maior risco nutricional foi a insuficiência cardíaca congestiva (p = 0,001). A avaliação da curva ROC entre espessura do músculo adutor do polegar e avaliação subjetiva global teve acuidade, com área de 0,822. Conclusão: A espessura do músculo adutor do polegar demonstrou ser um bom método de avaliação de risco nutricional.

Este estudo teve como objetivo fornecer valores de referência de medidas da Área de secção Transversa (AST) dos músculos multífidos em crianças de 6 a 9 anos. Para tanto, 41 crianças (20 meninos, 21 meninas) foram questionadas quanto à prática de exercícios físicos e submetidas a uma avaliação ultrassonográfica unilateral da AST dos multífidos em repouso ao nível de L5 e a uma avaliação antropométrica (peso, altura e IMC). Foi encontrada uma média da AST dos multífidos de 3,11±0,84 cm², não havendo diferenças entre os sexos (p=0,37), e tampouco entre as crianças sedentárias e as praticantes de exercícios físicos regulares (p=0,68). No entanto, detectou-se correlação positiva entre a AST e a idade (r=0,75; p

Objectives: It is known that COVID-19 has multisystemic effects. However, its early effects on muscle tissue have not been clearly elucidated. The aim of this study is to investigate early changes in the pectoral muscle in patients with COVID-19 infection., Materials and Methods: The pectoral muscle areas (PMA) and pectoral muscle index (PMI) of 139 patients diagnosed with COVID-19 were measured from chest CTs taken at the time of the first diagnosis and within 6 months after the diagnosis. The effect of the infection on the muscle area was investigated by evaluating whether there was a change between the two measurements. Lung involvement of the infection in the first CT was scored with the CT severity score (CT-SS). In addition, the effects of patients' clinics, CT-SS, length of hospital stay, and intubation history on changes in the muscle area were investigated., Results: When the PMA and PMI values were compared, there was a statistically significant decrease in the values in the control CT group compared to the first diagnosis CT group. The difference was found higher in intubated patients. CT-SS was associated with a decrease in PMI., Conclusion: COVID-19 is one of the causes of acute sarcopenia. Pectoralis muscle is part of the skeletal muscle, and there may be a decrease in the muscle area in the early period of the disease., (Copyright © 2023 SERAM. Published by Elsevier España, S.L.U.

Objective: To evaluate the effects of right sciatic nerve compression and cryotherapy on muscle tissue. Methods: We used 42 male Wistar rats, subdivided in the following Groups Control, Injury 3, Injury 8 and Injury 15 submitted to nerve compression and euthanized in the 3rd, 8th and 15th day after surgery. The Cryotherapy Injury 3 was entailed treatment with cryotherapy by immersion of the animal in recipient for 20 minutes during 1 day, then animals were euthanized at the 3rd day after surgery, and the Cryotherapy Injury 8 and the Cryotherapy Injury 15 was treated for 6 days, and euthanized at the 8th and 15th day after surgery. Functional evaluation was performed by the grasping strength of the right pelvic limb. The right tibialis anterior muscles were evaluated for mass, smaller diameter and cross-sectional area. In the Cryotherapy Injury 8 and the Cryotherapy Injury 15 groups, the hydroxyproline was dosed in the right soles. Results: In the compression there was a significant difference in the Injury Groups compared with the Control Group (p<0.05). In the smaller diameter, the compression in Control Group was higher than Injury 8 (p=0.0094), Injury 15 (p=0.002) and Cryotherapy Injury 15 (p<0.001) groups. The comparison between groups with euthanasia in the same post-operative period, a significant difference (p=0.0363) was seen in day 8th after surgery, and this result in Cryotherapy Injury Group was greater than Injury Group. In the fiber area, Control Group was also higher than the Injury 8 (p=0.0018), the Injury 15 (p<0.001) and the Cryotherapy Injury 15 (p<0.001). In hydroxyproline, no significant difference was seen between groups. Conclusion: Nerve damage resulted in decreased muscle strength and trophism, the cryotherapy delayed hypotrophy, but this effect did not persist after cessation of treatment. [ABSTRACT FROM AUTHOR]
