Redundancy and variation are characteristics of humans. Many muscles contribute to producing a movement at a joint, allowing different strategies for task performance. Further, the shoulders and back are involved in many tasks, including manual materials handling, but flexibility as to their relative roles in performing a task exists. In nursing, where manual patient handling (MPH) occurs daily, a risk of injury exists resulting from interactions with patients that may require awkward postures or sudden shifts in hand forces. Although some recommended MPH techniques have been advocated, many focus on lowering the risk of low back injury, without considering the effect of these techniques on other body regions. This study aimed to identify differences in shoulder and back physical exposures between performing self-selected and recommended patient handling techniques designed to reduce low back exposures. Twenty female participants performed three repetitions of five manual patient handling tasks using a self selected technique, followed by three repetitions of the same tasks using techniques learned in an interposed training session. Peak, mean and cumulative muscle activity, peak resultant moment, and ratings of perceived exertion were compared for each of the tasks before and after training, as well as identifying meaningful changes between the joints in mean population strength using a static strength prediction program. Significant decreases occurred at both the left and right shoulders and the low back for most measures, generally supporting the recommended techniques. Important exceptions existed, however, for the Sit-to-Chair tasks and Turn Toward tasks, where increases in several individual shoulder muscle activities, along with peak resultant moment, existed. Future recommendations for patient handling techniques should take into account potential negative exposures at the shoulders that may result from a back-centric injury avoidance paradigm.

No entanto, em alguns exercícios, tais como o long stretch, a progressão irá depender também da ação da gravidade sobre a massa corporal do praticante, assemelhando-se, em parte, à resistência utilizada no pilates solo. A presença dessas alavancas geradas pela ação da gravidade resulta em uma relação complexa entre a resistência imposta pelas molas e as forças agindo sobre a articulação do ombro, fazendo com que sua prescrição seja baseada em conhecimentos empíricos e avaliações subjetivas. O objetivo deste estudo foi analisar o efeito da resistência oferecida por molas e da posição do praticante, na força de reação do membro superior, e sobre o torque resultante e ADM do ombro, durante o exercício long stretch. Método: trata-se de uma pesquisa quase-experimental, realizada com 12 adultos saudáveis de ambos os sexos, com idade entre 20 e 37 anos, praticantes de Pilates por no mínimo um ano, sem restrições físicas. A coleta de dados consistiu na execução de cinco repetições do exercício long stretch em oito condições diferentes: sob a resistência de uma mola, duas molas, sem molas e carga máxima com e sem apoio dos joelhos no carrinho. O exercício foi realizado em um reformer instrumentado com duas plataformas de força acopladas à barra de apoio, e as forças aplicadas durante o movimento foram decompostas em componentes tangenciais e axiais ao membro superior, através da mensuração dos ângulos articulares obtidos pela cinemetria. A componente tangencial foi multiplicada pelo comprimento do membro superior a fim de estimar o torque resultante atuando sobre o ombro. Resultados: Quando realizado com apoio dos joelhos, o aumento na resistencia das molas levou ao incremento da força axial máxima e do pico de torque resultante em flexão entre todas condições analisadas, enquanto que a força tangencial sofreu apenas mudança em sua direção. No entanto, quando realizado na posição de prancha, o aumento na resistencia das molas apresentou efeito significativo entre as condições sem mola e com duas molas, levando ao aumento do torque resultante em flexão e diminuição da força tangencial. Quando comparada a condição sem mola com a condição uma mola, apenas a força axial maxima e a amplitude de movimento apresentaram diferença. Conclusões: A relação entre o efeito das alavancas impostas pela gravidade e a resistência das molas na mecânica do ombro é complexa, e sofre influência do posicionamento do praticante. O senso comum de que o exercício long stretch é essencialmente dirigido aos flexores de ombro é equivocado; a resistência imposta pelas molas pode alterar a demanda externa sobre a articulação do ombro, demonstrando que um mesmo exercício pode ter diferentes implicações clínicas.

Problem Statement: A paucity of research exists describing the relationship between lateral epicondylalgia (LE) and upper extremity (UE) strength, range of motion or joint characteristics, between the shoulder, elbow and wrist despite the close kinetic relationship. The primary purpose of this study was to describe these characteristics of the UE in female tennis players and a control group. Methods: This was a descriptive study of three groups: sample of active adult females with no elbow pain (control), non-symptomatic tennis players (NSTP), and symptomatic tennis players (STP) with LE. A convenience sample of three groups, 21 women each was recruited. A questionnaire was completed by each participant and a screening procedure was performed to confirm group assignment and gather tennis specific information. The dependent variables were collected at a one-time session for the dominant extremity of each subject and included UE passive motion, mean UE adjusted strength values, strength ratios, elbow carrying angle, posterior shoulder tightness, anterior glenohumeral joint (GHJ) laxity and shoulder impingement tests. Results: The STP group demonstrated significantly greater passive forearm pronation, higher internal/external rotation strength ratios, increased frequency of anterior GHJ hyperlaxity and positive Hawkins-Kennedy test results. Grip strength taken in elbow extension was significantly weaker in the STP group compared with the NSTP and control groups. The strength ratio of the upper/lower trapezius was significantly greater in the STP compared to NSTP group, but was not significantly different from the control group. The STP group demonstrated a trend toward greater passive motion in elbow hyperextension and supination, and a higher wrist flexion/extension ratio that did not reach statistical significance. Both tennis player groups demonstrated limited passive wrist flexion and shoulder internal rotation when compared to controls. No significant differences were found in tennis playing factors between the groups. Conclusion: Impairments in strength, range of motion, or motor control are hypothesized to contribute to the altered kinematics of the UE and may potentially lead to LE in recreational tennis players. Recognizing risk factors a priori may provide a framework to guide the physical evaluation, treatment plan and preventative techniques for the tennis player exhibiting symptoms of LE.

Title: Influence of physiotherapist intervention on shoulder muscular imbalance and movement stereotype in users of mechanical wheelchair. Objectives: The aim of the work is to find out to what extent a twelve-week strength training under the professional guidance of a physiotherapist can affect the users of mechanical wheelchairs (paraplegics) and their functional muscle tension in the shoulder area. Methods: This pilot multiple qualitative research took place from January to July 2021. Three paraplegics aged 39 to 46 participated voluntarily in the research. A kinesiological analysis was performed on each proband with an examination of the movement stereotype while riding a mechanical wheelchair. A diagnostic method with a tensiomyograph was performed for individual muscles of the shoulder girdle. Kinesological analysis and muscle measurements were performed before and after the intervention, which took place three times a week. Due to the unfavorable epidemic situation, it was carried out in the form of video transmission at home. The comparative method was used in the comparison section before and after the end of the physiotherapist's intervention during the training cycle of each proband. The obtained results were processed by the TMG 100 software, which meets the requirements for data...

La scoliose idiopathique de l’adolescence (SIA) est une pathologie de cause inconnue impliquant une déformation tridimensionnelle de la colonne vertébrale et de la cage thoracique. Cette pathologie affecte, entre autres, les vertèbres ainsi que les muscles paraspinaux. Ces composantes de la colonne vertébrale jouent un rôle important lors de la marche. Dix sujets témoins et neuf sujets SIA ont effectué dix essais de marche à vitesse normale sur un corridor de marche de dix mètres dans lequel était inséré deux plates-formes de force. De plus, un système de huit caméras (VICON) a permis de calculer les coordonnées tridimensionnelles des 30 marqueurs utilisés afin d’analyser la cinématique des sujets. Les variables faisant l’objet de cette étude sont les amplitudes totales, minimales et maximales des rotations des ceintures pelvienne et scapulaire dans les plans transverse et frontal de même que les coefficients de corrélation et de variation de ces segments. Des tests de Student ont été utilisés pour l’analyse statistique. Malgré le fait qu’aucune différence significative n’a été observée, dans aucun des plans, entre les amplitudes des rotations des ceintures pelvienne et scapulaire entre les groupes témoin et SIA, une différence significative en ce qui a trait aux minimums de rotations pelviennes et scapulaires, dans le plan transverse, a été observée. Cette différence suggère une asymétrie dans les rotations effectuées par ces segments à la marche à vitesse naturelle chez une population atteinte de SIA. / Idiopathic scoliosis is a tridimensional deformation of the spine and of the rib cage. The cause of this pathology is still unknown but its consequences affected different structures including vertebras and spinal muscles. These structures are essential in locomotion activities and this is why it is important to understand well consequences of having a scoliosis on walking. Ten control subjects and nine scoliotic subjects were asked to do ten walking trials at natural speed on a ten-meter walkway with two embedded force-plates. A 3D system (VICON) was also used to record kinematics of 30 body markers. Total, minimal and maximal range of motion (ROM) of pelvic and shoulder rotations, coefficients of variation and correlation were points of interest of this study. Student tests were used to compare groups. No statistically significant difference was observed between group’s total ROM in any planes but some differences were noticed between minimal ROM in coronal plane for pelvis and shoulders. That suggests an asymmetric rotation during natural speed walking in scoliotic group.
