Análise dos parâmetros espaço-temporais da marcha de gestantes durante atividades de dupla tarefa

Abstract

Based on the principle that the performance of dual task activities are requirements for independence on a daily basis, this study aims to verify whether dual task activities (DT) interfere with the spatiotemporal parameters of the gait of pregnant women. The study was carried out at the Gait Analysis Laboratory of the Clinical Center of the University of Caxias do Sul. The sample was composed of 24 women, aged between 18 and 40 years, divided into two groups: non-pregnant women and pregnant women, with pregnant women being over the 13th gestational week. To participate in the study, the participants consented and signed the Informed Consent Form. For the cognitive assessment, two questionnaires were used, the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). Then, the simple tasks (ST) were performed: the motor task of marching and the cognitive tasks of verbal fluency, subtraction arithmetic and reading on the cell phone. Afterwards, reflective markers were affixed to the anatomical points for performing the DTs. As for the questionnaires, the MMSE showed no difference between the groups, while the MoCA showed an average value for non-pregnant women statistically lower than that of pregnant women. Regarding the results of the analysis of the spatiotemporal parameters of the gait, in the intragroup comparison and between the groups, both showed no statistically significant changes in the comparison between the ST and the DTs. It is assumed that the results suffered effects due to the study participants being composed of a majority of the second gestational trimester, as it is demonstrated in literature that greater biomechanical changes happen in the third trimester.
