Résumé : The aims of this study were to analyze temporal and spatial parameters of gait during pregnancyin women with and without PGP, to evaluate the effect of pelvic belts on temporal and spatialgait parameters, and to compare two types of belts. A total of 46 pregnant women with PGP, 58healthy pregnant women and 23 non-pregnant women were recruited. Temporal and spatialparameters were analysed by an walkway. Two pelvic belts for pregnant women were used. Ananalysis of variance for repeated measures were used. In pregnant women with PGP, comparedto healthy pregnant women, gait cycle and stance phase times were lower and single supporttime was higher. Compared to the non-pregnant women, gait velocity and step length werelower. Stance phase and double support times were higher. During pregnancy, wearing a pelvicbelt modified gait velocity, single support phase, step length, step width, stance phase and toein/out in pregnant women with PGP. Gait adaptations in pregnant women with PGP showednearly the same changes found in women without PGP. The belts had an effect on gait inpregnant women with PGP, probably through a biomechanical and proprioceptive mechanism.
