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 pilot 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.

Outcome Measures

Primary Outcomes (5)

  • Evaluation of biomechanical properties of thoracolumbar fascia

    Measuring of the stiffness (N/m) of the thoracolumbar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side line position.

    Measurement the baseline stiffness values of Thoracolumbar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks

  • Evaluation of viscoelastic properties of thoracolumbar fascia

    Measuring of the relaxation time (ms) of the thoracolumbar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side line position.

    Measurement the baseline relaxation time values of Thoracolumbar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks

  • Evaluation of biomechanical properties of thoracolumbar fascia

    Measuring of the tone (Hz) of the thoracolumbar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side line position.

    Measurement the baseline tone values of Thoracolumbar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks

  • Evaluation of viscoelastic properties of thoracolumbar fascia

    Measuring of the creep of the thoracolumbar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side line position.

    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

  • Evaluation of biomechanical properties of thoracolumbar fascia

    Measuring of the decrement of the thoracolumbar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side line position.

    Measurement the baseline decrement values of Thoracolumbar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks

Secondary Outcomes (2)

Study Arms (3)

First trimester pregnant women (first pregnancy)

Pregnant women who are in their first pregnancy and in their first trimester will be evaluated.

Other: Evaluation of biomechanics and viscoelastic properties of Thoracolumbar fascia

Second trimester pregnant women (first pregnancy)

Pregnant women who are in their first pregnancy and in their second trimester will be evaluated.

Other: Evaluation of biomechanics and viscoelastic properties of Thoracolumbar fascia

Third trimester pregnant women (first pregnancy)
