An observational study in Pregnant Women, sponsored by Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey. Completed at 1 site in Turkey. Open to female participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-03-24.

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 pilot 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.
Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey is the lead sponsor of 104 studies on the registry; 28 are open to participants now.

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.
Foot length and width will be measured.
The amount of navicular drop of both feet will be measured.
Foot posture will be evaluated according to Foot Posture Index.
Evaluation of biomechanical properties of plantar fascia
Measuring of the stiffness (N/m) of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
Time frame: The measurement of the baseline stiffness values of plantar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks.
Evaluation of biomechanical properties of plantar fascia
Measuring of the decrement of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
Time frame: The measurement of the baseline decrement values of plantar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of biomechanical properties of plantar fascia
Measuring of the tone (Hz) of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
Time frame: The measurement of the baseline tone values of plantar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of viscoelastic properties of plantar fascia
Measuring of the creep of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
Time frame: The measurement of the baseline creep values of plantar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of viscoelastic properties of plantar fascia
Measuring of the relaxation time (ms) of the plantar fascia (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position.
Time frame: The measurement of the baseline relaxation time values of plantar fascia between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of Body Weight
Body weight (kg) will be measured
Time frame: The measurement of the baseline body weight between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of Body Mass Index (BMI)
BMI will be calculated as person's weight in kilograms divided by the square of height in meters
Time frame: The measurement of the baseline BMI between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of Foot Morphological Characteristics
Foot width (cm) will be measured
Time frame: The measurement of the baseline foot width between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of Foot Morphological Characteristics
Foot length (cm) will be measured
Time frame: The measurement of the baseline foot length between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
Evaluation of foot mobility
Navicular drop values will be measured
Time frame: The measurement of the baseline navicular drop values between 10-14 weeks, between 20-24 weeks and between 32-36 weeks
