Pelvic Girdle Pain (PGP) is reported by 50% of pregnant women and up to 11 years after pregnancy, 10% of women have persistent and per definition chronic PGP. Central (nervous system) sensitization that elicits pain hypersensitivity, may be one explanation.
The overall aim of this study is to explore features of central sensitization in pregnant women and its predictive ability on physical activity, functioning and health in women with PGP. Measurements of central sensitization will be done on two study groups, pregnant women with PGP and healthy controls. To identify women at risk to develop chronic pain in relation to a common pain experience ie PGP in pregnancy, may help us understand if central sensitization early in life explains why women develop chronic pain.
Pelvic Girdle Pain (PGP) is reported by 50% (60000) of pregnant women yearly in Sweden. PGP is expected to disappear after delivery. However up to 11 years after pregnancy, 10% of women have persistent and per definition chronic PGP with large impact on their physical activity, functioning,and health. Central (nervous system) sensitization, defined as an amplification of neural signaling within the central nervous system that elicits pain hypersensitivity, may be one explanation why 10% of women develop postpartum chronic PGP and related physical inactivity.
The overall aim of this study is to explore features of central sensitization in pregnant women and its predictive ability on physical activity, functioning and health in women with PGP. Two study groups, pregnant women with PGP and healthy controls (including non-native Swedish) will be included through maternity care units and a blog. Measurements of primary outcome central sensitization will be done. To identify women at risk to develop chronic pain in relation to a common pain experience ie PGP in pregnancy, may help us understand if central sensitization early in life explains why women develop chronic pain.

| Measure | Description | Time Frame |
|---|---|---|
| central sensitization measured by Patient Pain Drawing | spreading of pain | change from baseline (gestational week 20-30) at 6 weeks, at 6 months and at 12 months after delivery |
| central sensitization measured by conditioned pain modulation using an algometer and a occlusion cuff | Malfunctioning of descending nociceptive inhibitory pathways resulting in dysfunctional endogenous analgesia, assessed by a conditioned pain modulation (CPM)=
| change from baseline (gestational week 20-30) at 6 weeks, at 6 months and at 12 months after delivery |
| Measure | Description | Time Frame |
|---|---|---|
| Pregnancy Physical Activity Questionnaire | Physical activity and exercise are measured by this self-administered questionnaire which provides assessment of four domains of physical activity; ''Sports and Exercises', ''Household and Caregiving'', 'Transportation''and ''Occupation'. Since it measures the frequency and the duration of the activities, (an intensity value assigned to each activity), the minimum values are 0 but here are no maximum values. The activities can be analyzed by type, by intensity or for the total energy expenditure. |
| Measure | Description | Time Frame |
|---|---|---|
| Fear-Avoidance Beliefs Questionnaire subscale on physical activity (FABQ-PA) | Fear avoidance beliefs about physical activity. Minimum score 0 maximum score 24 where high scores mean worse outcome | change from baseline (gestational week 20-30) at 6 weeks, at 6 months and at 12 months after delivery |
| subscale Catastrophizing (CSQ-CAT),from the Coping Strategies Questionnaire |
