People with lower extremity and low back injury often demonstrate altered muscle recruitment patterns in the lumbopelvic region and hip. These altered recruitment patterns can result in dysfunctional movement, decreased stability, and pain. Clinicians frequently prescribe hip movements that target gluteal muscle activation to improve lumbopelvic stabilization. These dynamic lower limb movements are typically performed with cues to keeping the lumbopelvic region still. These exercises are effective at increasing lumbopelvic muscluature activation. However, their effect on gluteal muscl activation during hip movement is unclear. The purpose of these studies is to identify effective methods of lumbopelvic stability during hip movement on gluteal recruitment and determine the specific effect of the abdominal draw-in maneuver (ADIM) on gluteus medius recruitment during side-lying hip abduction (SHA) and side-lying hip abduction-lateral rotation (SHALR) in people with and without chronic low back pain (LBP).
