Abstract(s)
A marcha é influenciada por um conjunto de factores que resultam da interacção e organização própria de sistemas neurais e mecânicos, entre os quais, da dinâmica músculo-esquelética, da modulação pelos centros nervosos superiores, pela modulação aferente e é, também, assumida como sendo controlada pelo Gerador de Padrão Central (GPC), que se define como um programa central baseado num circuito espinal geneticamente determinado, capaz de produzir um ritmo associado a cada marcha. Apresenta-se como objectivo deste trabalho abordar quais os modelos explicativos para o funcionamento do GPC e qual a evidência científica, que continua a ter muitas divergências.
Walking is influenced by a number of factors that result from the interaction and self-organization of neural systems and mechanics, among which the muscle-skeletal dynamics, modulation by higher nervous centers, by afferent modulation and is also assumed to be controlled by the central pattern generator (CPG), which is defined as a central program based on a genetically determined spinal circuitry, be capable of produce a rate associated with each action. It presents as purpose of this study is to address the explanatory models for operating the CPG and what is the scientific evidence, which continues to have many differences.
