Plain English Summary

Background and study aims
Many women are thought to experience low back pain (LBP) during their pregnancy, with symptoms typically increasing as pregnancy advances, and often continuing after birth. For many women, pain can become so severe that it leads to daily functional limitations, including time off work and disrupted sleep. There are some studies indicating that women often feel frustrated that their symptoms are not taken seriously, but we know little about the true extent of this problem in Northern Ireland, what treatments are available to women, and how helpful women think they are. Therefore, this study is taking place in to find out the best ways to collect information from a group of pregnant women about whether, or not, they develop LBP by following them from their 20 to 22-week scan until six months after their baby is born. This will be done by exploring the LBP history, initial symptoms and how they progress, types of treatment received and outcomes by asking women to complete a secure online questionnaire at four different time points, two during pregnancy and two after the birth. The findings will be used to design a much larger study of this kind in the future aimed at improving the management of pregnancy-related LBP.

Who can participate?
Pregnant women attending the Ulster Maternity Unit for their anomaly scan. They do not have to have LBP to take part.

What does the study involve?
Midwives direct potential participants to a member of the research team on the day of their 20 to 22-week scan. The meeting lasts for approximately one hour, and allows the researcher to check the participant is eligible to take part, and answer any questions they may have about the study. Eligible participants are asked at this point to complete a study consent form, and a number of secure online questionnaires. These questionnaires are then repeated when participants are between 31-34 weeks pregnant and then six weeks and six months after they have had their baby.

What are the possible benefits and risks of participating?
There will be no direct benefit to participants. However, they will have an important input to the future design of services to manage pregnancy-related LBP. Participation will involve a time commitment to complete the questionnaires at each of the follow-ups. Also, there is a risk of participants becoming upset, for example, when answering questions about previous pregnancies. Every step has been taken to minimise these risks.

Pregnancy related low back pain


An online data collection tool (designed using Qualtrics software) will automatically generate a unique identifier for each participant and, once consent has been provided (at the beginning of the questionnaire), participants will be directed to sections on general demographic information, parity and risk factors for LBP such as; history of (low back Pain) LBP, hypermobility and / or amenorrhea, and information about current LBP. For the purposes of this study, LBP will be defined using the standard criteria of ‘pain or discomfort in the area between the lowest rib and the gluteal folds (+/- referral into lower limb) lasting 7 days or more since the beginning of pregnancy’. Women reporting LBP at baseline (T0) will be asked whether they have already received, or been referred for treatment and/or out-of-pocket expenses incurred for treatment, along with data relating to:
1. Pain intensity and bothersomeness
2. LBP-related functional disability (using the Roland Morris Disability Questionnaire)
3. Days off work / early maternity leave
4. LBP-related fear
5. Health-related quality of life
6. Global perceived effect of treatment

The questionnaires will be completed at the anomaly scan between 20 to 22 weeks’ gestation; between 31 to 34 weeks’ gestation; 6 week’s post-partum; and 6 month’s post-partum.

Drug names

Primary outcome measure

Feasibility of recruitment and retention of pregnant women is recorded using the online questionnaire within the timeframe of the study namely beginning at 20 to 22 weeks’ gestation, again at 31 to 34 weeks’ gestation, at 6 week’s post-partum, and finally 6 month’s post-partum.

Secondary outcome measures

1. Pain intensity and bothersomeness is measured using an 11-point numerical rating scale (NRS)
2. LBP-related functional disability is assessed using the Roland Morris Disability Questionnaire
3. Days off work/early maternity leave is assessed using an online questionnaire
4. LBP-related fear is measured using the Fear-Avoidance Beliefs Questionnaire
5. Health-related quality of life is measured using the EuroQol-5d-5l
6. Global perceived effect of treatment is measured using the Global Perceived Change Scale
7. Use of and satisfaction with, health care (including NHS and out-of-pocket expenses) associated with pregnancy related LBP are measurd using an online questionnaire

All outcomes are assessed at at T0 (20-22 weeks gestation), T1 (31-34 weeks gestation), T2 (6 weeks postpartum) and T3 (6 months postpartum)
