Síndrome da Dor Patelofemoral, Eletromiografia, Exercício Físico, Força MuscularResumo
O tratamento da dor patelofemoral (DPF) deve ser composto por exercícios de fortalecimento muscular para o quadril, joelho ou quadril e joelho de forma associada, para melhorar a dor e a função. Entretanto a literatura não estabelece quais exercícios são eficazes. Objetivo: Determinar os resultados de um protocolo de exercícios de fortalecimento muscular com carga externa adicional de 20% do peso corporal na dor, capacidade funcional, ativação e força muscular de quadríceps para mulheres com DPF. Método: Relato de série de casos, que avaliou mulheres com DPF (n= 10), submetidas a 12 atendimentos com exercícios resistidos para quadríceps e quadril, com carga externa adicional de 20% do peso corporal, realizadas em seis semanas. As participantes foram avaliadas por meio da Escala Visual Analógica (dor), Anterior Knee Pain Scale e Lysholm Knee Scoring Scale (capacidade funcional), eletromiografia de superfície do Vasto Medial Oblíquo, Vasto Lateral e Reto Femoral (ativação muscular) e dinamometria isométrica (força muscular) no momento de pré-intervenção, pós-intervenção e follow-up (após quatro semanas). O teste de Friedman com post hoc de Bonferroni estabeleceu as diferenças entre os momentos avaliados. Resultados: Dor, capacidade funcional e força muscular melhoram significativamente após o tratamento e no follow-up (p<0,05). Apenas a força muscular demonstrou redução no follow-up em comparação ao momento de pós-intervenção, porém ainda superior à pré-intervenção. Os resultados de ativação muscular não apontaram diferenças. Conclusão: Exercícios de fortalecimento com carga externa de 20% do peso corporal demonstraram ser efetivos para dor, capacidade funcional e força muscular para mulheres com DPF.
