Detailed Description

The subjects will be tested at enrollment and during weeks 20, 24, 28, 32, 36, 40 of their pregnancy, as well every 4 weeks postpartum up to 6 months. The following protocol will be used:

  1. Subjects will also be asked to answer a short health questionnaire.
  2. The following data will be recorded each time: height, minimum stance width, circumference measurements of the chest, abdomen, hip and each thigh as well as a supine fundal height. A full body side-profile photo was also taken to determine the curvature of the spine.
  3. A session questionnaire will be used to determine if the subject had fallen or noticed any changes in their daily activity.
  4. In a seated position, the following measurements will be recorded: 1-minute heart rate variability (HRV) with paced breathing, temporal scan body temperature, respiration rate, heart rate, blood pressure and SpO2 (these last three will be measured bilaterally).
  5. Subject will undergo posturography testing using the modified Clinical Testing of Sensory Integration in Balance (mCTSIB) protocol: four 30 s tests in the following conditions: eyes open on a rigid surface (NSEO), eyes closed on a rigid surface (NSEC), eyes open on a compliant surface (PSEO), and eyes closed on a compliant surface (PSEC).
  6. At the end of the posturography testing, heart rate, blood pressure and SpO2 will be re-measured bilaterally in the standing and then seated positions, as will be the seated HRV.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Subjects
Adult, healthy pregnant women undergoing Posturography Evaluation, Anthropometrics, Vitals and answering Health and daily activity questionnaires
Diagnostic test: Posturography Evaluation
Posturography testing using the modified Clinical Testing of Sensory Integration in Balance (mCTSIB) protocol: the subjects will be required to stand on a hard or compliant surface in a comfortable posture, with eyes open or closed
Other Names:
  • Balance Testing
  • CAPS® Testing
Diagnostic test: Anthropometrics
measurement of height, minimum stance width (feet together or as close as they can be), circumference of the torso at the breast level, of the abdomen, of the hip, and of each thigh, and supine fundal height
Diagnostic test: Vitals
measurement (bilateral and seated/standing if applicable) of temperature, respiration rate, heart rate, blood pressure, pulse oxygenation and heart rate variability
Other: Health and daily activity questionnaires
one time general health questionnaire as well as session questionnaires asking the subjects if they have fallen since their last testing session and how comfortable they are in doing daily activities

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Stability Score
Time Frame: From enrollment to 6 month post partum
The Stability Score (calculated as percentage ratio of the actual sway and the theoretical limit of stability) will be used to investigate how balance changes during pregnancy and how it correlates to anthropometrics, vitals and questionnaires
From enrollment to 6 month post partum

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Center of Pressure (CoP) coordinates
Time Frame: From enrollment to 6 month post partum
The CoP coordinates (standard posturography measurements) will be also used to investigate how balance changes during pregnancy and how it correlates to anthropometrics, vitals and questionnaires
From enrollment to 6 month post partum
