- Estudo electromiográfico do conflito sub-acromialPublication . Oliveira, Leonor; Carvalho, Paulo; Moreira, CamiloObjectivo: estudar a actividade muscular no complexo articular do ombro e tronco durante o serviço e a sua relação com o Conflito Sub-Acromial. Metodologia: estudo observacional, analítico, transversal. Amostra de 15 atletas de voleibol distribuídas em 3 grupos e avaliadas através de electromiografia de superfície em músculos do ombro e do tronco. Foi avaliada a percentagem de activação muscular nas diferentes fases do serviço. Resultados: aumento de actividade do Trapézio Superior e Infraespinhoso e diminuição do Recto Abdominal e Oblíquo Externo no grupo com Conflito Sub-Acromial. Conclusão: existem diferenças significativas nas atletas com e sem Conflito Sub-Acromial.
- Electromyographic analysis of impingement syndrome: Comparison in volleyball athletesPublication . Oliveira, Leonor; Moreira, Camilo; Carvalho, PauloThe purpose of this study was to analyze the muscle activity of the trunk and shoulder complex during the volleyball serve and the possible correlation with the mechanisms of injury of impingement syndrome (IS). The athletes (female, n=15) were divided in three groups: 1) with pain, 2) without pain but with history of shoulder pain, and 3) without pain. Surface electromyographic data were collected from shoulder and trunk muscles and synchronized with video image recorded at high-speed. The data analysis revealed an increased activity in both Upper Trapezius and Infraespinatus and a decreased activity in Rectus Abdominus and External Oblique in the group with IS.
