- A Diagonal Movement Pattern of Arm Elevation and Depression in Overhead Throwing Athletes: An Exploratory Kinematic Analysis for Clinical ApplicationPublication . Morais, Nuno; Ferreira, Joana; Gordo, Jéssica; Vilas-Boas, J. Paulo; Pascoal, Augusto GilAssessing scapular position and motion during functional arm movement patterns may add relevant information to the evaluation of the clinical status and athletic performance of overhead sports athletes’ shoulders. This study aimed to examine the three-dimensional scapular kinematics of elite volleyball players with (n = 11) and without scapular dyskinesis (n = 11) in comparison to non-athletes (n = 27). Four distinct arm elevation/depression tasks were assessed: shoulder abduction/adduction, flexion/extension, scaption, and a diagonal movement pattern mimicking throwing (proprioceptive neuromuscular facilitation diagonal 2 for flexion/extension or PNF–D2– flx/ext). Kinematic data was recorded from the spiking/dominant shoulder using an electromagnetic system (FASTRAK, Polhemus Inc., Colchester, VT, USA); MotionMonitor v9 software, Innovative Sports Training, Inc., Chicago, IL, USA). The study compared scapular rotations at 15◦ intervals of humero-thoracic (HT) angles, ranging from minimum to 120◦. Significantly different 3D scapular kinematics were observed between traditional arm motion tasks and PNF–D2 arm motion task (HT angle × task interaction effect, p < 0.001, 0.275 ≤ η2p ≤ 0.772). However, when considering the combined influence of phase, HT angle, task, and group factors, no differences were found between groups (phase × HT angle × task × group, p ≥ 0.161, 0.032 ≤ η2p ≤ 0.058). The inclusion of a functional arm movement pattern when evaluating scapular position and movement in overhead athletes does not appear to be mandatory. However, these findings are preliminary and highlight the need for more research in this area.
- A força de preensão manual da população adulta e a sua relação com a incapacidade funcional em contexto clínicoPublication . Roldão, Elisabete; Pascoal, Augusto Gil
- A Força de Preensão Manual da População Adulta e a sua Relação com Condições de Saúde – Um Possível ProtocoloPublication . Roldão, Elisabete; Pascoal, Augusto GilA forma como as pessoas agarram os objetos, as suas implicações na saúde e na realização das atividades e tarefas do dia-a-dia e as limitações de cada preensão são importantes para a medicina, reabilitação, design de produtos, de entre muitas outras áreas. A força de preensão fornece informações importantes sobre a funcionalidade do indivíduo e ajuda na monitorização e implementação de estratégias de manutenção ou recuperação da força muscular global. O objetivo principal deste estudo é alargar a avaliação da força de preensão da mão, ampliando seu espectro para outras configurações de preensão, usadas em atividades do dia-a-dia, relacionando-as com a sua utilização funcional. Tendo como base a nova Taxonomia das Preensões, resultante de um projeto financiado pela Comissão Europeia, implementaremos três estudos. Inicialmente propomos analisar as caracteristicas das preensões da nova taxonomia e verificar se é possível serem avaliadas com o Dinamômetro G200 e o Pinchmetro P200 do Biometrics® E-Link. Seguidamente verificaremos essa possibilidade, efetuando a avaliação das preensões identificadas, em participantes saudáveis. Num segundo estudo, avaliaremos a força de preensão e pinça, nas configurações anteriormente identificadas, em participantes com patologia da mão. Os participantes serão recrutados, por conveniência, em Hospital e Clínica de Reabilitação, na região de Lisboa, Portugal. Adultos com idades compreendidas entre os 20 e os 60 anos, sem patologia da mão, integram o grupo de control. O grupo de estudo terá as mesmas caracteristicas e patologia musculoesquelética da mão ou neurológica periférica. São critérios de exclusão doenças degenerativas ou neurológicas centrais e estado de gravidez em ambos os grupos. Por fim, implementamos um estudo correlacional para verificar a possibilidade de estabelecer um quadro de valores de referência de força de preensão com diretrizes para avaliação de cada uma das preensões, os valores de força e as tarefas nas quais as preensões são executadas no dia-a-dia. O estudo encontra-se em fase de recolha de dados. Identificámos 14 preensões de mão passíveis de serem avaliadas com o Dinamômetro G200 e o Pinchmeter P200 do Biometrics® E-Link. Destas, nove são avaliadas com recurso à dinamometria sendo preensões de carácter global e cinco com recurso ao Pinchmeter pois são pinças.
- Grasps in daily tasksPublication . Roldão, Elisabete; Pascoal, Augusto GilActivities are done using the hands. With the hand’s grasps are performed on objects, grabbing, manipulating, and using them. There are 33 grasps, according to the recent European Grasp Taxonomy. Grasps are the way objects are grabbed, in a secure mode, independent of the position of the wrist, forearm or arm. To better understand the use of the hands and the grasps in the daily activities and relate it with the difficulties identified by the patients, when they have a hand pathology, we need to know in which tasks are they performed. Using a Delphi Panel, composed by 20 Occupational Therapists also Hand Therapist, considerer experts in this area, we collect data, in two rounds. For each one of the 33 grasps was created a question, with some characteristics of the grasp, such as the number of used fingers and the diameter of the grasped object. Experts were asked to identify the tasks where the grasps are used. An image of the grasp was also presented to exemplify. After the language uniformization, the elimination of tasks that doesn’t complied with the grasp’s characteristics and unification of very similar tasks, there were identify tasks used in work, leisure, and self-care activities. For each one of the grasps there were identified at least 13 tasks. It will be easier for therapists to relate the difficulties in the use of the grasps with the performance of activities in daily living.

- Kinematic Comparison and Description of the 3-Dimensional Shoulder Kinematics of 2 Shoulder Rotation TestsPublication . Pascoal, Augusto Gil; Morais, NunoObjectives: The purpose of this study was to compare shoulder external rotation range of motion (ROM) during the hand-behind-neck (HBN) test and a standard shoulder external rotation test and to describe the 3-dimensional scapular motion during the HBN test. Methods: An electromagnetic tracking device was used to assess the dominant shoulder of 14 healthy participants while performing active full ROM in a standard shoulder external rotation test in an elevated position (EREP) and in the HBN test. The humeral and scapular 3-dimensional positions at the end of EREP and HBN were compared using a paired-sample t test. A correlation analysis was performed between humeral and scapular angles to assess the contribution of scapular motion to the full shoulder ROM during the HBN test. Results: No significant differences were found between the HBN test and the EREP at the end-range of the glenohumeral external rotation (HBN: 15.6° ± 6.3° vs EREP: 23.4° ± 4.7°; P = .08) and on scapular internal-external rotation (HBN test: 21.2° ± 6.3° vs EREP: 15.6° ± 1.8°; P = .23). Significant differences were found in scapular upward rotation (HBN: 21.2° ± 6.3° vs EREP: 15.6° ± 1.8°; P b .01) and scapular spinal tilt (HBN: − 0.4° ± 2.3° vs EREP: 8.1° ± 2.1°; P b .01). There was a positive correlation between the humeral angles and scapular internal and posterior spinal tilt angles with the HBN test. Conclusions: The results of the present study showed that, in young asymptomatic participants with no known shoulder pathology, the end-range of shoulder rotation was similar in the HBN test and in a standard shoulder rotation test. During the HBN test, the scapula assumed a more internal and anterior spinal tilted position at the end-range of active shoulder external rotation. These results suggest that the HBN test may be used to assess the end-range of glenohumeral external rotation.
