- Abstract
- Background: l iffle research has been done into whether the degree of joint mobility of the pelvis and hips during pregnancy is linked to the course of labour (mode of delivery, length of labour). While the static pelvic bony landmarks have been demonstrated to act as low cost non-invasive measures to predict pregnant women at risk of requiring intervention, a link has not yet been assessed into whether there is a relationship between the movement of those same pelvic landmarks and the course of labour.Objective: The purpose of this study was to explore the relationship between the range of motion of the bony landmarks of the hips and pelvis and the course of labour. Design: An observational pilot cohort study.Method: Participants were recruited via social media networking sites (n=10, primigravida within the third trimester without any known complications). Prior to the birth measurements were taken from each participant by a single rater: A modified version of an Osteopathic test to diagnose movement of the Rhomboid of Michaelis (proposed by Molinari) was used in combination with assessment of rotation of the hip joints. Baseline characteristic data was also gathered including assessment of hypermobility. Participants were then contacted again after the birth to retrieve follow up data about the birth and baby. Outcome measures: 1. Length of the second stage of labour 2. Use of intervention during labour. Analyse- IT was used for both linear and binary regression analysis.Results: Follow up data was retrieved from 100% of the participants (n=10). Participants all experienced vaginal births. Those individuals with imbalanced hip rotation and a low hypermobility score combined with a lower than average pelvic mobility (from Left Posterior Superior Iliac Spine to Right Posterior Superior Iliac Spine) were seen to be more likely to experience assisted delivery, pain relief and prolonged second stage of labour. Discussion: While previous research has demonstrated that static bony landmark measurements act as predictors of complications during labour, this study was able to take this hypothesis further and suggest that certain mobility tests appear to act as predictors of the length of the second stage of labour as well as highlight those individuals at risk for intervention. Although the numbers for this pilot study were low the results indicate that further research on a larger scale is called for. Conclusion: Results suggest that both Hip Rotation and Rhombus of Michaelis tests act as predictors of birth outcome when combined with other baseline data. However they do not act alone as predictors of birth outcome.
