The parameters of muscle origin and insertion points in the pectoral girdle and forelimbs of Caiman latirostris were identified by basic anatomical, kinesiological and biomechanical approach. This identification was made with two adults males specimens of C. latirostris, on average, 1.50cm in length, belonging to the collection of the Wild Animal Research Laboratory of the Federal University of Uberlândia/MG, Brazil. In this study, isometric postures intercalated with rotary movements were found, as well as a large cross-sectional area in most of the extensor and stabilizer muscles, giving them greater strength and denoting functional and organizational inferences. Based on the findings, it was possible to recognize and predefine the behavior of the species under investigation, correlating the duration, direction and dimension of the activity levels.

OBJECTIVE: To evaluate and measure the scapular positioning, and establishing its correlation with functional postural analysis and degree of upper extremities disability in sonographers. MATERIALS AND METHODS: Eighteen physicians divided into two groups - symptomatic individuals with pain for more than six months, and asymptomatic individuals - were interviewed and submitted to physical assessment with application of the Brazilian version of the DASH questionnaire. Functional measurements of scapular inclination angles and upper limbs positioning were obtained during the ultrasound scanning. The Mann-Whitney U test was utilized for analyzing the disability questionnaires; the t-Student test, for upper limbs positioning; ANOVA, for scapular inclination angles, and the Spearman's test for correlation between the functional upper limbs positioning and disability degree. RESULTS: A significant difference between symptomatic and asymptomatic groups was observed in the first 30 items of the DASH questionnaire as well as in the four study-related questions. Measurements of scapular positioning presented significant differences between the groups in the frontal plane at 90° and 120°. No significant difference was found for the analysis of functional upper limbs positioning. CONCLUSION: Changes in the scapular positioning may result in upper limbs dysfunction, and the application of the DASH questionnaire can indicate the level of pain and disability of an individual.

Ocorrendo isoladamente, as fraturas da clavícula e as luxações acromioclaviculares são lesões muito comuns. A combinação de uma luxação acromioclavicular e de uma fratura do terço lateral da clavícula não é rara. Entretanto, existem muito poucos casos descritos de luxações acromioclaviculares associadas a fraturas do terço médio da clavícula; aquelas associadas a fraturas do terço medial são ainda mais raras. Nós reportamos o caso de um indivíduo adulto do sexo masculino que sofreu uma luxação acromioclavicular (tipo IV) associada a uma fratura extra-articular desviada da extremidade medial da clavícula (grupo 3 de Almann) em um acidente ciclístico. O paciente foi tratado na fase aguda com redução aberta e fixação interna das duas lesões. Na avaliação clínica, 12 meses após a cirurgia, o paciente apresentava-se assintomático, com mobilidade ativa e passiva completa, força e resistência normais e simetria das cinturas escapulares. As radiografias e a tomografia computadorizada tridimensional mostravam subluxação posterossuperior persistente da articulação acromioclavicular e consolidação anatômica da fratura clavicular. Fractures of the clavicle and acromioclavicular dislocations are very common injuries when they occur separately. The combination of an acromioclavicular dislocation and a fracture of the lateral third of the clavicle is not rare. However, there are very few reported cases of acromioclavicular dislocations associated with fractures of the middle third of the clavicle; those associated with fractures of the medial third are even rarer. We report the case of an adult male who suffered an acromioclavicular dislocation (type IV) associated with a displaced extra-articular fracture of the medial end of the clavicle (Almann group 3) in a cycling accident. The patient was treated during the acute phase with open reduction and internal fixation of the two lesions. At the clinical evaluation 12 months after the surgery, the patient was asymptomatic, with full active and passive mobility, and normal strength and endurance of the shoulder girdle. Radiographs and a three-dimensional CT scan showed persistent posterosuperior subluxation of the acromioclavicular joint and anatomical consolidation of the clavicular fracture. more...

O conhecimento da atividade eletromiográfica produzida durante a realização de exercícios para o ombro pode auxiliar na determinação de sua aplicabilidade clínica. O objetivo desta pesquisa foi avaliar a influência da direção da carga e condição da extremidade na atividade elétrica de músculos da cintura escapular e membro superior durante a realização de exercícios com a extremidade distal fixa e carga externa axial (EFCA) e extremidade livre com carga externa rotacional (ELCR). Foram selecionadas 20 voluntárias (23,2 anos ± 0,9) sedentárias. Foram avaliados os mm. tríceps do braço, bíceps do braço, peitoral maior, trapézio e deltóide. Foi realizado o registro eletromiográfico de superfície, durante a realização de dois exercícios com EFCA e dois com ELCR, utilizando 100% da resistência máxima previamente estabelecida. Os valores de RMS normalizados pela contração voluntária máxima foram comparados por meio de um modelo de efeitos mistos com nível de significância de 5%. Nessas condições experimentais, os resultados do presente estudo mostraram que exercícios semelhantes, classificados pela condição da extremidade e a direção da carga aplicada ao membro superior, promovem níveis semelhantes de atividade eletromiográfica em apenas parte dos músculos estudados. Esses achados questionam a capacidade do sistema de classificação utilizado neste estudo de predizer o tipo de resposta muscular esperada na realização de diferentes tarefas de mesma classificação. The knowledge of the electromyographic activity produced during shoulder exercises can help in determining its clinical applicability. The purpose of this study was to assess the influence of the load direction and the extremity condition on the electrical activity of the shoulder girdle and upper limb muscles during exercises with fixed distal extremity and external axial load (FEAL) and mobile extremity with rotational external load (MERL). Twenty 23.2 ± 0.9 years old female sedentary volunteers were selected. The triceps brachii, biceps brachii, major pectoral, trapezium and deltoid muscles were assessed. The surface electromyography was recorded during two FEAL and two MERL exercises using 100% of the previously established maximal resistance. The RMS values normalized by the maximal voluntary contraction were compared by a mixed effect model with 5% significance level. In these experimental conditions, the results found in the present study have shown that similar exercises classified by extremity condition and load direction applied on the upper limbs promote similar levels of the electromyographic activity only in part of the assessed muscles. These findings discuss the ability of the classification system used in this study to predict the type of the muscular response expected during different tasks with the same classification.

Se seleccionaron 20 voluntarias (23,2 años ± 0,9) sedentarias. Ellos estimaron el grosor en mm. de los tríceps del brazo, los bíceps del brazo, pectoral mayor, trapecio y deltoides. El registro electromiográfico de superficie se hizo, durante la realización de los ejercicios con EFCA y de los con ELCR, usando 100% de la resistencia máxima establecidos previamente. Se compararon los valores de RMS normalizados por la reducción máxima voluntaria a través de modelo de efectos mixtos con un nivel de significancia de 5%. En estas condiciones experimentales, los resultados del estudio presente mostraron que ejercicios similares, clasificados por la condición de la extremidad y la dirección de la carga aplicada al miembro superior, promoven niveles similares de electromiografía con actividad en sólo parte de los músculos estudiados. Estos descubrimientos cuestionan la capacidad del sistema de la clasificación usada en este estudio para predecir el tipo de respuesta muscular esperada en el logro de tareas diferentes de misma clasificación. more...
