In a recent experiment, participants wore special shoes that induced pronation (inward roll) of the foot while walking. This resulted in altered pelvic and hip motion—more specifically, the pelvic position was more inclined on the contralateral side during the loading phase of gait, there was less rotation of the pelvis to the contralateral leg, and the hip also tended to be more internally rotated—which could contribute to pelvic and lower back disorders over time. Doctors of chiropractic are trained to assess and correct foot biomechanics to promote normal gait patterns. Brazilian Journal of Physical Therapy, May 2021
