| Popis | Treadmill and overground gait are from the mechanical point of view considered to be equivalent. Previous studies show that treadmill walking, as an unusual experience, requires one to six minutes of familiarization in young healthy subjects. Treadmill walking may be therefore used in studies of adaptation to unfamiliar gait environment. Pregnancy influences an array of factors affecting gait parameters. As pregnancy progresses altered balance and higher risk of falling were reported. Purpose of current study was to compare the trend of adaptation to a treadmill walking at three pregnancy stages measured by ground reaction force at maximal weight acceptance and push-of phases and by the stride duration. In this study six pregnant subjects participated at three pregnancy stages. Two hundred step cycles measured by Pedar Insole System were obtained from the five minute long treadmill walking at the velocity of 3 km.h-1. These step cycles were divided into five subgroups of forty step cycles, each subgroup was corresponding approximately to one minute of treadmill gait. To assess differences between step subgroups of each measurement Kruskall Wallis test followed by post hoc testing was used. The level of significance was set to 0.05. Statistically significant changes in subgroups of analysed force and time variables were observed during all pregnancy stages, especially between first, second and fifth minute of walking. These trends are highlighted in the third trimester of pregnancy where statistically significant changes from the first to the second, third, fourth and fifth subgroup were more evident. Results of current study show altered process of familiarization to the treadmill walking in advanced phases of pregnancy. However, during all pregnancy stages individual human movement variability has a huge impact on statistically significant changes between analysed step groups during the five minute long walking. |
