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 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.
Interventions
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.
OTHEREvaluation of Foot Morphological Characteristics
Foot length and width will be measured.
OTHEREvaluation of navıcular mobility
The amount of navicular drop of both feet will be measured.
OTHEREvaluation of Foot Posture
Foot posture will be evaluated according to Foot Posture Index.
