The Effects of Abdominal Draw - in Maneuver With Shoulder Isometric Contractions on Abdominal Muscles Thickness in Healthy Person

This study was conducted in order to examine whether abdominal draw-in maneuver (ADIM) with isometric shoulder flexion, extension, adduction, and abduction selectively contracted deep abdominal muscles. This study’s subjects were 13 males 17 females. In order to evaluate the comparison of effects of ADIM and ADIM with isometric shoulder flexion, extension, adduction and abduction, measurements were made on transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) using a real-time ultrasonic diagnostic imaging system. Each position was repetitively measured three times with a real-time ultrasonic diagnostic imaging system and their mean values were used for analysis. The ADIM with isometric shoulder flexion, extension, adduction and abduction significantly increased the thickness of TrA relative to the ADIM only (p＜.05). The ADIM with isometric shoulder abduction significantly increased the thickness of IO compared to the ADIM only (p＜.05). The ADIM with isometric shoulder extension and abduction significantly decreased the thickness of EO compared to the ADIM only and the ADIM with isometric shoulder extension significantly decreased the thickness of EO relative to the ADIM with isometric shoulder adduction (p＜.05). ADIM with isometric shoulder abduction is an effective method to selectively strengthen deep abdominal muscles and therefore may be employed as an intervention for trunk stabilization.
