Introduction: Increased joint load on the medial compartment of the knee during gait is a mechanical factor responsible for pain and progression of medial knee osteoarthritis. The knee external adductor moment of force is a kinetic parameter that correlates with the joint load in the medial compartment. Objective: The aim of this study was to conduct a narrative review of the biomechanics strategies during gait of individuals with medial knee osteoarthritis that reduce external adductor moment of force of the knee. Methods: The review of the literature was conducted in the databases MEDLINE, PUBMED and PEDro and included articles published between 2000 and 2011. It was selected transversal, theoretical, correlational and longitudinal studies as well as controlled clinical trials. Results: Decreased gait velocity, increased external rotation of the foot, increased internal abductor moment force of the hip and lateral trunk inclination to the side of the support limb are compensatory strategies used to reduce the external adductor moment of force of the knee during gait of individuals with medial knee osteoarthritis. The lateral trunk inclination may be beneficial in a short term, however it decreases the activity of the abductors muscles of the hip during the support phase of the gait favoring compensation that could result in the progression of medial knee osteoarthritis. Conclusion: Strengthening of the abductors muscles of the hip reduces pain, improves the function and prevents compensations that in a long term could possibly accelerate the progression of the medial knee osteoarthritis. Resumo Introdução: O aumento da carga articular no compartimento medial do joelho durante a marcha é um fator mecânico responsável pela dor e progressão da osteoartrite medial do joelho. O momento de força externo adutor do joelho é o parâmetro cinético que correlaciona com a carga articular no compartimento medial do joelho. Objetivos: O objetivo deste estudo foi realizar uma revisão narrativa da literatura das estratégias biomecânicas durante a marcha em indivíduos com osteoartrite medial do joelho que reduzem o momento de força externo adutor do joelho. Métodos: A revisão da literatura foi realizada nas bases de dados MEDLINE, PUBMED e PEDro, incluindo artigos publicados entre 2000 e 2011. Foram selecionados artigos transversais, teóricos, de correlação e longitudinais, assim como ensaios clínicos controlados. Resultados: A diminuição da velocidade da marcha, aumento do ângulo de rotação externa do pé e do momento de força interno abdutor do quadril, inclinação lateral do tronco são estratégias compensatórias que reduzem o momento de força externo adutor do joelho durante a marcha em indivíduos com osteoartrite medial do joelho. A inclinação lateral do tronco pode ser benéfica em curto prazo, porém diminui a atividade dos músculos abdutores do quadril durante a fase de apoio da marcha favorecendo compensações que podem acarretar na progressão da osteoartrite medial do joelho. Conclusão: O fortalecimento dos músculos abdutores do quadril reduz a dor, melhora a função e previne compensações que em longo prazo poderiam acelerar a progressão da osteoartrite medial do joelho.
El objetivo de este estudio fue demostrar la llegada al cerebro de la molécula de eritropoyetina recombinante humana, con bajo contenido en ácidos siálicos, administrada por vía nasal en el gerbo de Mongolia y el primate Macaca fascicularis, así como la seguridad de aplicación nasal en ambas especies. Se emplearon 18 gerbos de Mongolia a los cuales se les administró eritropoyetina marcada con I125. La radioactividad asociada al bulbo olfatorio y al cerebelo fue determinada mediante un contador gamma. En un segundo experimento se administró eritropoyetina por vía nasal en 10 monos. El contenido de eritropoyetina en suero y líquido cefalorraquídeo obtenido por punción lumbar fue determinado por un ELISA que cuantifica la cantidad de molécula presente por mL. Se detectó un 0,8% de la radioactividad aplicada por la vía nasal, en el bulbo olfatorio, 5 min después de la aplicación en el gerbil de Mongolia. En el M. fascicularis se determinó un 0,15% de la dosis aplicada por vía nasal en el líquido cefalorraquídeo lumbar a los 15 min. No se observaron cambios en los parámetros sanguíneos en estas especies. Los resultados sugieren que la vía nasal constituye una alternativa de acceso no invasivo y seguro de la molécula de eritropoyetina humana recombinante al SNC, que puede tener uso como neuroprotector en accidentes cerebrovasculares, que constituyen en la actualidad un problema de salud humana. Our propose was to demonstrate the brain access of the recombinant human erythropoietin, with low sialic acid content, in the Mongolian gerbil and Macaca fascicularis, as well as the safety of nasal administration in both species. Eighteen Mongolian gerbils received intranasally I125 labelled erythropoietin. Olfactory bulb and cerebellum-associated radioactivity were measured by a gamma counter. In a second experiment, erythropoietin was intranasally administered to 10 monkeys. Erythropoietin content in serum and cerebrospinal fluid obtained by lumbar puncture was determined by an ELISA method. From the intranasal administered radioactivity, a 0,8% was detected in the olfactory bulb at 5 min. In M. fascicularis, a 0,15% of the dose was determined in the cerebrospinal fluid 15 min after the intranasal administration. Treatment related-changes in blood parameters in both species were not observed. Results suggest that nasal route may be an alternative, non invasive and sure mode of access to the brain for the erythropoietin, which can be used as neuroprotector in stroke, a current health problem nowadays.
