Objective: To assess resistance to passive isokinetic movements at speci®ed speeds and range of motion, as a measure of muscular tonus. Methods: A group of 12 subjects with complete traumatic spinal cord injury and a group of 12 able-bodied subjects were analysed, distinguishing the level of spasticity in the SCI group. Maximum eccentric peak torque was observed in passive isokinetic¯exion (F) and extension (E) knee movement in displacements of 30, 60 and 1208 per second. Results: The Student t-test showed that the average torque in the injured group was signi®cantly higher than in the control group (F=1208 per second, P50.001). Variance analysis showed that the lower level presented lower torque levels (E=60 and 1208 per second, P50.032), while those in the higher level presented higher torque levels (F and E=60 and 1208 per second, P50.032) when compared to the control group. In the control group the Student t-test (P50.0006) showed a signi®cantly dierent muscle behavior (Flexion4Exten-sion Torque). Conclusion: By using isokinetic assessment it was possible to quantify hypertonic spasticity in a group of subjects with spinal cord injury, distinguishing groups with higher and lower levels of spasticity as compared to a control group.
Força muscular é uma variável comprovadamente importante de ser avaliada não somente para obter bom desempenho na prática de esportes, como também para identificar indivíduos que possam estar em um grupo de risco para lesões musculoesqueléticas. Poucos estudos descrevem valores de força para diferentes articulações em atletas de elite do futebol feminino. O objetivo deste estudo é descrever esses valores. Para isso, 23 atletas da seleção brasileira de futebol feminino, em preparação para as Olimpíadas de 2004, foram avaliadas nos movimentos de flexo-extensão de tronco, rotação interno-externa do quadril e flexo-extensão dos joelhos no dinamômetro isocinético Cybex 6000 (Lumex Inc. Ronkonkoma, NY). Foram encontrados os valores médios de torque máximo, expressos em Nm: rotação interna do quadril: 23,1; rotação externa do quadril: 25,6; flexão de tronco: 213,2; extensão de tronco: 267,7; extensão de joelho: 181,4; flexão de joelho: 102,0. Os valores encontrados devem ser considerados quando o indivíduo testado equivaler ao grupo estudado.
