Biomechanical and Viscoelastic Properties of Plantar Fascia in Pregnant Women
Study Details
Study Description
Brief Summary
The feet, which are support surfaces, are adapted to the physiological relaxation and biomechanical changes that occur during pregnancy. In this adaptation, it has not been objectively clarified how the plantar fascia, which plays a very important role in maintaining the height of the plantar arch, undergoes a change. Therefore, the aim of this study is to investigate the normative values of trimester-specific biomechanical and viscoelastic properties of the plantar fascia, which adapts to changes in foot structure during pregnancy.

| Group: Pregnant women (first-timed pregnant) This group will consist of women in first trimester of pregnancy |
Other: Evaluation of biomechanics and viscoelastic properties of plantar fascia
The biomechanical (Tone-Hz, Stiffness-N/m and decrement) and viscoelastic (creep and relaxation time-ms) properties of the plantar fascia will be measured in the side lying position.
Measurements will be made with the ankle in neutral position.
Other: Evaluation of Foot Morphological Characteristics
Foot length and width will be measured.
Other: Evaluation of navıcular mobility
The amount of navicular drop of both feet will be measured.
Other: Evaluation of Foot Posture
Foot posture will be evaluated according to Foot Posture Index.

Outcome Measures
Primary Outcome Measures
- Evaluation of biomechanical properties of plantar fascia [The measurement of the changes from baseline stiffness values of plantar fascia at 12., 22. and 34. weeks.]
Measuring of the stiffness (N/m) of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
- Evaluation of biomechanical properties of plantar fascia [The measurement of the changes from baseline decrement values of plantar fascia at 12., 22. and 34. weeks.]
Measuring of the biomechanical decrement of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
- Evaluation of biomechanical properties of plantar fascia [The measurement of the changes from baseline tone values of plantar fascia at 12., 22. and 34. weeks.]
Measuring of the tone (Hz) of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
- Evaluation of viscoelastic properties of plantar fascia [The measurement of the changes from baseline creep values of plantar fascia at 12., 22. and 34. weeks.]

BMI will be calculated as person's weight in kilograms divided by the square of height in meters
- Evaluation of Foot Morphological Characteristics [The measurement of the changes from baseline foot width at 12., 22. and 34. weeks.]
Foot width (cm) will be measured
- Evaluation of Foot Morphological Characteristics [The measurement of the changes from baseline foot length at 12., 22. and 34. weeks.]
Foot length (cm) will be measured
- Evaluation of foot mobility [The measurement of the changes from baseline navicular drop values at 12., 22. and 34. weeks.]
Navicular drop values will be measured
- Evaluation of foot posture [The measurement of the changes from baseline foot posture characteristics at 12., 22. and 34. weeks.]
Foot posture will be evaluated according to foot posture index.
