Resumo: | Patients with upper motor neuron lesions (UMNL) experience movement and posture dysfunction, which hinder their mobility and performance in daily activities. Traditionally, spasticity has been considered the major determinant of movement dysfunction in these individuals. However, there is evidence that changes in muscle characteristics may contribute to movement deficits in this population. The aim of this study was to critically appraise the literature regarding characterization of passive stiffness, length-tension relationship and extensibility of muscles of individuals with UMNL. The review shows that patients with UMNL present increase in passive stiffness, shifts in the length-tension relationship, and decrease in muscle extensibility. Such alterations appear to be the result of tissue remodelling in response to specific patterns of use, with histochemical and histological alterations. Such changes in muscle tissues, in turn, may contribute to movement and posture patterns presented by these patients. The interplay between muscle properties and movement function needs to be addressed in more detail to allow the elaboration of more efficient strategies of intervention to promote functional improvement of the population with neurological deficits. |

A espasticidade tem sido considerada tradicionalmente o principal determinante das disfunçõesmotoras desses indivíduos. No entanto, há evidências de que alterações nas características musculares dessa população possam contribuir para os défices motores. O objetivo deste estudo foi realizar uma análise crítica da literatura referente à caracterização da rigidez passiva, curva comprimento-tensão e comprimento dos músculos de indivíduos com lesão do neurônio motor superior (LNMS). A literatura revisada traz evidências de que pacientes com LNMS apresentam aumento da rigidez passiva, deslocamento das curvas comprimento-tensão e diminuição de comprimento muscular. Tais alterações parecem decorrer de remodelaçãotecidual em resposta a padrões diferenciados de uso, com modificações histoquímicas e histológicas do tecido muscular. As alterações das características musculares podem, por sua vez, contribuir para os padrões de postura e movimento atópicos. A interação entre as propriedades musculares e a função motora precisa ser melhor investigada, para que possam ser elaboradas estratégias de intervenção mais eficazes para a promoção de ganhos funcionais na população com défices neurológicos.Universidade de São Paulo.
