Brief summary
There is anatomical fascial continuity and functional connection between the plantar fascia, which has important roles in foot biomechanics, and the fibers of the Achilles tendon, and the change that will occur in any of these tissues is reflected in the other. However, it has not been objectively clarified how the tissue properties of the Achilles tendon, which plays an important role in foot biomechanics, such as the plantar fascia, change with 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 Achilles tendon, which adapts to changes in the foot structure during pregnancy.
Interventions
The biomechanical and viscoelastic properties of the Achilles tendon will be measured in the side lying position. Measurements will be taken from two different points with the ankle in the neutral position.
The mobility of foot, morphological changes of foot and foot posture will be evaluated

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of biomechanical properties of achilles tendon | Measurement the baseline stiffness values of Achilles tendon between 10-14 weeks, between 20-24 weeks and between 32-36 weeks. | Measuring of the stiffness (N/m) of the achilles tendon (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position. |
| Evaluation of viscoelastic properties of achilles tendon | Measurement the baseline creep values of Achilles tendon between 10-14 weeks, between 20-24 weeks and between 32-36 weeks. | Measuring of the creep of the achilles tendon (with MyotonPro, Myoton AS, Tallin, Estonia) in the side lying position. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of foot mobility | The measurement of the baseline navicular drop values between 10-14 weeks, between 20-24 weeks and between 32-36 weeks. | Navicular drop values will be measured |
| Evaluation of Body Weight | Measurement the baseline body weight (kg) between 10-14 weeks, between 20-24 weeks and between 32-36 weeks. | Measuring of the Body Weight |
| Evaluation of foot posture | The measurement of the baseline foot posturebetween 10-14 weeks, between 20-24 weeks and between 32-36 weeks. | Foot posture will be evaluated according to foot posture index |
| Evaluation of foot morphological properties | The measurement of the baseline foot length between 10-14 weeks, between 20-24 weeks and between 32-36 weeks. | Foot length will be measured |
| Evaluation of Body Mass Index (BMI) | Measurement the baseline BMI values at between 10-14 weeks, between 20-24 weeks and between 32-36 weeks. | BMI (kg/m2) will be calculated as person's weight in kilograms divided by the square of height in meters. |
