Effects of abdominal drawing-in maneuver with pressure biofeedback, foam-roller and quadruped on lumbopelvic stability and muscle activities in lumbar rotation syndrome

Abstract

The abdominal drawing-in maneuver (ADIM) exercise has been com-monly applied to recover lumbopelvic stability and normal movement in the clinical field. Although many researchers investigated its effects us-ing several methods, there is further need for comparing those methods. The purpose of this study was to assess the effects of ADIM with three different methods including a pressure biofeedback unit, a foam-roller, and the quadruped posture on lumbopelvic rotation and muscle activities. Twenty-five healthy participants (14 males, 11 fe-males) who volunteered for this study were randomly divided into three intervention groups. We obtained pre- and postintervention data through application of a three-dimensional motion analysis system and a surface electromyography. Results showed that lumbopelvic rotation degree was significantly decreased in all groups (P < 0.05). The muscle activities of external oblique, internal oblique of left side, and gluteus maximus were significantly increased (P < 0.05). The muscle activities of erector spinae and biceps femoris were not significantly different (P > 0 .05). The muscle activity of internal oblique of the right side showed significant differences (P < 0.05), between ADIM with pressure biofeedback group and ADIM with foam-roller group, and ADIM with foam-roller group and ADIM with quadruped group. Three kinds of ADIM were effective to recover lumbopelvic stability. This study suggests that the proper method of ADIM should be applied to a given patient considering abilities to maintain equilibrium and to control muscular strength.
