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.
