- Brief Summary
Lower back pain (LBP) during pregnancy is a frequent syndrome: it concerns two thirds of pregnant women. This complaint isn't routinely searched for and therefore underdiagnosed. Furthermore, few solutions are given to these women in order to reduce their pain, and indirectly to improve everyday life. What's more, LBP is the cause of many work interruptions. Physical exercise during pregnancy is recommended by the National College of Gynaecologists and Obstetricians for low risk pregnancies. Several techniques have proven to be efficient.
The main objective of our study is to assess the benefit of regular practice of standardised Stretching Postural® postures in patients presenting "de novo" lower back pain during pregnancy.
The Stretching Postural® technique comprises of static postures involving muscular contractions and stretches. This allows the strengthening of the postural muscles, including the paravertebral muscles. After a short learning period, postures can be done autonomously by the patients. The postures are adaptable to each and everyone's morphology and physical limitations.
Our study is an open, prospective, randomised monocentric superiority trial in parallel branches involving major patients during low risk pregnancies. These women suffer from "de novo" lower back pain during the second and third trimesters of their pregnancies. Each patient will be randomly assigned to one of the following 2 groups:
* Stretching Postural® group (group A): usual prevention methods (ergonomic education) and Stretching Postural® postures.
* "Control" group (group B): usual prevention methods only.
Patients presenting "de novo" LBP are included in the study after a routine consult then randomly separated into two groups. During the initial consult, the physician assesses inclusion and judgement criteria, collects informed consent from the patients and teaches them the usual prevention methods as well as, concerning group A, Stretching Postural® postures. Computerized support agendas are given in order to improve observance.
Patients are evaluated at day 0 (initial evaluation), after 4 weeks (intermediate) and after 8 weeks (final), according to the main judgment criterion, as well as on secondary pain criteria by the Concise Pain Questionnaire, on their quality of life, the rate of work interruptions and their satisfaction rate. Neonatal outcome is collected at birth. Intermediate phone interviews will allow psychological support and improve observance. Inclusion is scheduled to last 22 months; each subject will be followed during a period of 2 months. The total duration of the study is 2 years.
Expected results are a decrease in back pain and an improvement of the quality of life in group A. Decrease in pain scale, equivalent to overall pain during the last week between the two groups will be our main judgment criterion. In order to detect a difference of 1.5 pain scale points (on a scale from 1 to 10) with an alpha risk of 5%, 80% magnitude and a standard deviation of 2, 56 subjects are necessary; 28 in each group.
Perspectives: This study will allow for a better diagnosis of lower back pain during pregnancy, and, consequently, for the implementation of routine means of care such as collective or private lessons in Stretching Postural® and the supply of personalised prevention documents.

- Primary Outcome Measures
Name Time Method Change in Lower Back Pain 2 months Evaluated on the Numeric Pain Rating Scale (0 = No pain to 10 = Worst possible pain). This scale, validated, is a self-assessment of the average pain felt during the last week collecting by an evaluation questionnaire. It's part of Concise Pain Questionnaire's questions.
- Secondary Outcome Measures
Name Time Method Assessment of the analgesic efficacity on the Numeric Pain Rating Scale representing the average pain on the last week at 4 weeks. week 4 Evaluated on the Numeric Pain Rating Scale (0 = No pain to 10 = Worst possible pain). Questionnaire will be completed during intermediate consultation.
