Characteristics of running motion in patients with groin pain history

Abstract

The purpose of this study was to clarify the characteristics of running motion in a patient with groin pain history using biomechanics of 3D motion analysis. 11 of the legs that had pain in the groin in the past year were designated as groin pain group (GP group), and 14 of the legs with no history of pain were designated as the control group (C group). These two were compared and examined. As a result, Trendelenburg sign that the pelvis on the swing side was drop during the support period was recognized as a running characteristic of the GP group. The hip joint of the GP group was in the adduction position. The ankle joint of the GP group had a small change in angle from supination to pronation. The results suggest that improvement of pelvic, hip and ankle joint movements during running is necessary for rehabilitation and prevention of groin pain.
