background: the comparison between voluntary and automatic contraction of deep abdominal muscles in patients with nonspecific low back pain (nlbp) may justify being the best treat for them. the aim of this case-controlled study was to compare changes in the thickness of the transverses abdomin is (tra) and internal oblique (io) muscles during the abdominal drawing-in maneuver (adim) and the act...

[Purpose] The purpose of this study was to assess the effects of draw-in exercise on abdominal muscle activity in the standing and supine positions. [Methods] Twenty healthy women participated in this study. The subjects were required to complete two draw-in exercises (standing and supine positions) using a biofeedback pressure unit. The root mean square (RMS) values of the EMG data were expres...

The purpose of this study was to effects of abdominal draw-in maneuver and core exercise with 4 weeks using the musculoskeletal ultrasonography on muscle thickness and disability in subjects with low back pain. Twenty patients with nonspecific back pain (abdominal draw-in maneuver group: n= 10, core exercise group: n= 10) were recruited in the study. Both group received exercise intervention 3 ...
