ABSTRACT
Background/aim: Hormonal and structural changes that occur during pregnancy cause alterations in body biomechanics. These alterations reach their peak in the last trimester. Adaptive changes that appear in the foot result in pain in the foot and ankle. Pedobarography is a noninvasive measurement method that can be used to understand the origin of such pain. Materials and methods: One hundred and thirty-one pregnant women who did not have a foot or ankle problem prior to pregnancy volunteered to take part in the study. Pain was quantified by a visual analog scale (VAS). A cut-off value of 2.95 was taken to divide the subjects into two groups: Group 1 (n = 70) with VAS scores of <2.95 and Group 2 (n = 61) with VAS scores of ?2.95. Plantar pressure measurements were taken by Tekscan HR Mat using midgait protocol. Results: Forces experienced by the total right foot area, right forefoot, and the midfoot for both feet were significantly higher in Group 2 (P < 0.05). Contact area was significantly larger in Group 2 (P < 0.05). Conclusion: Results indicate that presence and severity of foot pain during pregnancy are related to the force distribution along the foot, especially at midfoot and the contact area.
