EVALUATING CYCLIC PELVIC MOVEMENT IN PATIENTS WITH ACETABULAR LABRAL TEARS: A CASE-CONTROLLED PILOT STUDY

Abstract

Acetabular labral tears are a common cause of hip pain, but specific diagnosis can be difficult due to limitations in current physical examination techniques and radiographic imaging. Pelvic dynamics were captured in 18 participants (10 labral tear patients) who performed single leg squats and stance exercises. Comparisons were made between the pathologic and non-pathologic legs of patients and between patients and controls. The analysis of bilateral symmetry showed significant differences in most parameters implying unique patient compensatory dynamics. Bilateral symmetry was found to be significant in detecting differences in movement patterns and may become a useful tool for clinical evaluation.
