Fig 1.
Experimental setup and foot pressure distribution measurements.
A–the participants were asked to walk barefoot along a ~6-m walkway at comfortable self-selected speeds. Vertical foot pressure was recorded by the force plate (40x40 cm) located in the middle of the walkway. B–foot division into 9 regions (to evaluate the corresponding indicators of foot loading—DAI, FRI, MLI): medial (1) and lateral (2) heel; medial (3) and lateral (4) foot arch; first (5), second-third (6) and fourth-fifth (7) metatarsal bones heads; hallux (8) and lesser toes (9).

Foot loading characteristics in the 1st (P1), 2nd (P2) and 3rd (P3) trimesters of gestation.
A–dynamic arch index (mean±SD). B–foot angle (mean±SD). Upper colour footprints in A and B illustrate examples of averaged right foot pressure distribution patterns of individual subjects in the 1st, 2nd and 3rd trimesters of gestation.
