Flat feet may be tied to a common cause of hip pain, study suggests
NCT ID NCT07674433
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study looks at whether people with flat feet (pes planus) are more likely to have piriformis syndrome, a condition that causes pain in the hip and lower back. Researchers will compare foot posture and pain in adults aged 18-65 who have piriformis syndrome with those who do not. The goal is to better understand any connection between foot structure and this type of pain.
