Abstract: The aim of the study was to review aspects of the displacement of the center of mass and energy cost of walking in children with cerebral palsy. The methodology used was a bibliographical review, whose articles had been chosen using the database PubMed and Google Scholar. There is unanimity from the studies that describe the locomotion of the hemiplegic children with increased vertical displacement of center of mass, ineffi cient exchange between kinetic and potential energy and elevated energy cost when compared with normal children. The mechanisms that explain these fi ndings seem to have strong relation with the muscular co-contraction and the deformity in plantarfl exion. Therefore, evaluation of the locomotion through cinematography and energy expenditure index is effi cient to detect the effects of medical and therapeutic interventions.

Key words: Cerebral palsy - Hemiplegia - Gait

 

Resumo: O objetivo do estudo foi revisar aspectos relacionados ao deslocamento do centro de massa e gasto energético na caminhada de criancas hemiplegicas decorrentes da Paralisia Cerebral (PC). A metodologia empregada foi uma revisao bibliografica, cujos artigos foram escolhidos utilizando a base de dados PubMed e Google Scholar. Ha uma unanimidade entre os estudos, que descrevem a locomocao das criancas hemiplegicas com maior deslocamento vertical do centro de massa (CM), inefi ciente troca entre energia cinetica e potencial e maior gasto energetico quando comparadas as criancas saudaveis. Os mecanismos que explicam esses achados nao estao bem definidos, mas parecem ter forte relacao com a co-contracao muscular e a deformidade em flexao plantar presentes nos pacientes hemiplegicos. Portanto, meios de avaliacao da locomocao como a cinemetria e indice de gasto energetico sao eficazes para acompanhar a trajetoria dos resultados das intervenções terapeuticas.
