TORSO KINEMATICS DURING GAIT DIFFER BETWEEN PREGNANT FALLERS AND NON-FALLERS 1 , 2

More than 27% of women fall while pregnant [1, 2]. Falls are a leading cause of trauma-related hospital admissions during pregnancy [3]. Changes in gait during pregnancy have been hypothesized to be a reason for increased falls. Several authors have examined pregnancy-related alterations to gait mechanics, such as increased anterior pelvic tilt, hip flexion, and stance phase hip adduction, as well as a wider base of support [4]. We previously reported increased thoracic extension and greater frontal plane movement of C7 during gait and increased movement of the center of mass in the third trimester [5, 6]. Also, Wu et al. reported a reduction in thoracic and pelvic rotational ROMs in late-stage pregnancy [7].
