Biomechanical and Viscoelastic Properties of Thoracolumbar Fascia in Pregnant Women

Recruiting

• Conditions: Pregnant Women; First Pregnancy
• Interventions: Other: Evaluation of biomechanics and viscoelastic properties of Thoracolumbar fascia

• Registration Number: NCT05335330
• Lead Sponsor: Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey

Brief Summary

Pregnancy causes the development of biomechanical adaptations in the musculoskeletal system, especially in the lumbopelvic region. In this context, the thoracolumbar fascia (TLF) is the most important structure in this region and is an exoskeleton for the muscles of the lumbar region. However, it has not been objectively clarified how the TLF adapts to the changes in the lumbopelvic region during pregnancy. Therefore, the aim of this study is to investigate the trimester-specific biomechanical (stiffness, decrement and tone) and viscoelastic (creep and relaxation time) properties of the TLF, which adapts to the lumbopelvic region changes in pregnant women.

Primary Outcome Measures

Name	Time	Method
Evaluation of biomechanical properties of thoracolumbar fascia	Measurement the baseline decrement values of Thoracolumbar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks	Measuring of the decrement of the thoracolumbar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side line position.
Evaluation of viscoelastic properties of thoracolumbar fascia	Measurement the baseline creep values of Thoracolumb Measurement the baseline creep values of Thoracolumbar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks	Measuring of the creep of the thoracolumbar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side line position.

Secondary Outcome Measures

Name	Time	Method
Evaluation of Body Weight	Measurement the baseline body weight (kg) at evaluation time	Measuring of the Body Weight
Evaluation of Body Mass Index (BMI)	Measurement the baseline BMI values at evaluation time	BMI (kg/m2) will be calculated as person\'s weight in kilograms divided by the square of height in meters.
