Análise da marcha durante atividades de dupla tarefa em gestantes do segundo e terceiro trimestre gestacional

Abstract

AIMS: To analyze the influence of gestational trimesters on the kinematic parameters of gait during the performance of dual-task activities. Methodos: Descriptive observational study, with a cross-sectional design. The gait of a total of 29 pregnant women, ten from the second trimester, and nine from the third trimester, were analyzed. Ten participants from the control group were also recruited. Data were collected through cognitive, single-task and dual-task analysis. Descriptive statistics were used, with measures of central tendency and variability. For comparisons between groups, the unpaired t test was used. For the analysis of the gait results of each group, a one-way ANOVA was performed, followed by Tukey's post-hoc, with a significance level of p≤ 0.05. Results: In comparison with simple gait, during dual-task activities, pregnant women in the second trimester showed statistically significant differences in the kinematic variables of speed and cadence gait in the three types of dual-task, stride length and time in the dual tasks of verbal fluency and reading on cell phone. The third trimester pregnant women showed statistically significant results in speed during the double task of subtraction, speed and stride length in the dual task of verbal fluency and cadence and stride time in cell reading. Conclusions: It is concluded that different dual-task activities interfere in the kinematic parameters of gait in pregnant women in the second and third trimester, when compared to the execution of simple gait.
