Factors Associated With Disability in Postpartum Lumbopelvic Pain

3 września 2026 zaktualizowane przez: Seda Saka, Halic University

Clinical, Biomechanical, Psychological, and Biochemical Factors Associated With Functional Disability in Women With Postpartum Lumbopelvic Pain: A Cross-Sectional Study

Postpartum lumbopelvic pain may affect functional ability, daily activities, physical performance, psychological well-being, and health-related quality of life. The aim of this observational cross-sectional study is to investigate clinical, biomechanical, psychological, and biochemical factors associated with functional disability in women with postpartum lumbopelvic pain.

Approximately 45 women aged 18 to 50 years who are 6 to 15 months postpartum and have persistent low back pain and/or pelvic girdle pain will be enrolled. General functional disability will be assessed using the Oswestry Disability Index (ODI), and pelvic-girdle-specific symptoms and activity limitations will be assessed using the Pelvic Girdle Questionnaire (PGQ). Pain intensity during activity, at rest, and at night will be evaluated using visual analogue scales (VAS).

Psychological status will be evaluated using the Edinburgh Postnatal Depression Scale (EPDS), and health-related quality of life will be assessed using the physical and mental component scores of the 12-item Short Form Health Survey (SF-12). Biomechanical assessments will include diastasis recti abdominis and trunk muscle endurance using flexor endurance, extensor endurance, prone plank, right side-plank, and left side-plank tests.

Mode of delivery will also be recorded. Biochemical evaluation will include circulating C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-alpha), and cortisol. The study will examine the relationships between functional disability and these clinical, biomechanical, psychological, and biochemical variables.

Szczegółowy opis

This observational cross-sectional study is designed to comprehensively evaluate clinical, biomechanical, psychological, and biochemical factors associated with functional disability in women with postpartum lumbopelvic pain.

Women aged 18 to 50 years who are between 6 and 15 months postpartum and have experienced persistent low back pain and/or pelvic girdle pain for at least three months will be screened for eligibility. Participants meeting the predefined inclusion and exclusion criteria will undergo a standardized clinical assessment.

General functional disability will be evaluated using the Oswestry Disability Index (ODI). Pelvic-girdle-specific symptoms and activity limitations will be assessed using the Pelvic Girdle Questionnaire (PGQ). Pain intensity will be evaluated separately during activity, at rest, and at night using 0-100 mm visual analogue scales (VAS).

Psychological status will be assessed using the Edinburgh Postnatal Depression Scale (EPDS). Health-related quality of life will be evaluated using the physical and mental component scores of the 12-item Short Form Health Survey (SF-12).

Biomechanical assessment will include evaluation of diastasis recti abdominis and trunk muscle endurance. Diastasis recti abdominis will be assessed during an abdominal curl-up. Trunk endurance will be evaluated using flexor endurance, extensor endurance, prone plank, right side-plank, and left side-plank tests. Mode of delivery will also be recorded.

Biochemical assessment will include circulating C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-alpha), and cortisol. Blood samples will be obtained at approximately 10:00 a.m. and analyzed by specialist biochemistry personnel.

The primary objective of the study is to examine the relationship between functional disability and clinical, biomechanical, psychological, and biochemical factors. Additional analyses will investigate associations among ODI, PGQ, pain intensity, EPDS, SF-12 physical and mental health scores, trunk endurance, diastasis recti status, mode of delivery, and circulating biomarkers.

Opis środka
Ramy czasowe
Oswestry Disability Index (ODI)
Ramy czasowe: At the single study assessment
General functional disability will be assessed using the Oswestry Disability Index (ODI). The ODI consists of 10 sections scored from 0 to 5, producing a raw score from 0 to 50. The raw score will be converted to a percentage score ranging from 0 to 100%, with higher scores indicating greater disability.

Diastasis Recti Abdominis Status
Ramy czasowe: At the single study assessment
Diastasis recti abdominis will be assessed by palpation 2 cm above the umbilicus while the participant performs an abdominal curl-up in the supine position. The examiner will place the fingers transversely across the linea alba to estimate the separation between the medial borders of the rectus abdominis muscles. Diastasis recti will be classified as present when the inter-recti distance is at least two fingerbreadths and absent when the distance is less than two fingerbreadths.
At the single study assessment
Trunk Flexor Endurance
Ramy czasowe: At the single study assessment
Trunk flexor endurance will be evaluated using a McGill-based flexor endurance test. Participants will sit with the hips and knees positioned at 90 degrees and the trunk initially supported at approximately 60 degrees. Timing will begin when the support is removed and will end when the participant can no longer maintain the standardized position. Endurance duration will be recorded in seconds. Three trials will be performed and the mean duration will be used for analysis. Higher values indicate greater trunk flexor endurance.
At the single study assessment
Trunk Extensor Endurance
Ramy czasowe: At the single study assessment
Trunk extensor endurance will be assessed with a McGill-based extensor endurance test. The participant will be positioned prone with the pelvis and lower limbs stabilized while the unsupported trunk is maintained in a horizontal position. Timing will stop when the participant can no longer maintain the required horizontal position. Endurance duration will be recorded in seconds. Three trials will be performed and the mean duration will be used for analysis. Higher values indicate greater trunk extensor endurance.
At the single study assessment

The duration for which the correct position can be maintained will be recorded in seconds. Three trials will be performed and the mean duration will be used for analysis. Higher values indicate greater right lateral trunk endurance.
At the single study assessment
Left Side-Plank Endurance
Ramy czasowe: At the single study assessment
Left lateral trunk endurance will be evaluated using the side-plank endurance test. The participant will maintain the standardized side-plank position while supported on the elbow and feet.

Ramy czasowe: At the single study assessment
Anterior trunk endurance will be evaluated using the prone plank test. Participants will maintain a standardized plank position with the body aligned and supported on the forearms and toes. Timing will end when the standardized position can no longer be maintained. Endurance duration will be recorded in seconds. Three trials will be performed and the mean duration will be used for analysis. Higher values indicate greater trunk endurance.
At the single study assessment
