CORRELAÇÃO ENTRE VELOCIDADE DA MARCHA E PADRÃO DE ATIVAÇÃO DOS MÚSCULOS ESTABILIZADORES DO QUADRIL EM SUJEITOS SUBMETIDOS À ARTROPLASTIA TOTAL DE QUADRIL

Abstract

Objective: The research aimed to evaluate the correlation between gait speed and activation pattern of the hip stabilizer muscles in subjects undergoing total hip arthroplasty (THR). Method: This is a cross-sectional study, with subjects submitted to THR due to Osteoarthritis (OA), interviewed using a structured questionnaire and physical assessment before starting physiotherapeutic rehabilitation. In the physical assessment, data related to the main complaint, assessment of the muscle activation pattern of hip abductors, flexors and extensors carried out through the load cell connected to the electromyograph and assessment of gait speed through the 6-meter walk test were collected. Results: A significant difference was found regarding the muscle strength of the abductors, in which those subjects with less muscle strength had lower gait speed. As for the electromyographic data, no significant differences were found between the participants who had preserved and reduced gait speed. Conclusion: There was a significant difference when comparing the muscle strength of subjects undergoing THR between the groups that showed preserved and reduced gait speed, with the same group of subjects that had reduced gait speed showing lower strength of the hip abductor muscles
