Official title
Validation of a Non-invasive Image Technique for Studying Pregnant Women´s Lordosis. Relation Between Lordosis and Childbirth Outcome.
Overview
The study consists of collecting measurement data of the rachis in pregnant women and the subsequent outcome of her delivery. This will make it possible to validate a non-invasive imaging technique through software that can be used to study this anatomical curve proposing a new measurement method for the angle of lordosis. Finally, with the research data, the investigators will try to find a correlation between these variables (angle of lordosis and delivery outcome.
Interventions
- Diagnostic test Arrow Test
It consists of taking the widest measurement between the rope of a plumb bob on her upper and lower back. - Diagnostic test Angle measurement by imaging device
First, three anatomical landmarks are located, and a sticker is placed on each of them: the 12th thoracic vertebra at its intersection with the midline descending from the axilla, the greater trochanter, and the anterior superior iliac spine. After this, the woman will be asked to stand in a normal position facing forward with her hands crossed over her shoulders, and a picture will be taken and pixelated with anything that could identify her. The angle formed by the three stickers will be measu
