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.
Study Type
OBSERVATIONAL
Enrollment

The biomechanical and viscoelastic properties of the Thoracolumbar fascia will be measured in the side line position. Measurements will be taken from three different points; L1, L3-4 and L5 level.

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