Activating Transversus Abdominis Muscle

Activating Transversus Abdominis Muscle: A Comparison Of Two Different Feedback Methods

Transversus abdominis (TrA) is an important muscle for spinal stabilization. Abdominal draw-in maneuver (ADIM) is a method that selectively activates TrA without activating external oblique (EO) and internal oblique (IO) muscles. Individuals with low back pain may have some troubles to understand proper contraction of TrA. Therefore, to contract the TrA, two different feedback techniques have been used to instruct. In this observational study we aim to investigate the effects of two different biofeedback methods to teach patients the proper activation of TrA muscle using ADIM. We aim to find out the differences between visual and traditional tactile biofeedback and decide which one is practical and easy to teach the patients in clinical environment.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Group1; visual feedback	Other: abdominal hallowing maneuver; abdominal hallowing maneuver includes tucking navel in and up. To be able to control the effect of breathing it was instructed to start the maneuver at the end of the expiration. During the maneuver it was instructed to focus on increasing the thickness of TrA without increasing the thickness of IO and EO
Group2; traditional feedback	Other: abdominal hallowing maneuver; abdominal hallowing maneuver includes tucking navel in and up. To be able to control the effect of breathing it was instructed to start the maneuver at the end of the expiration. During the maneuver it was instructed to focus on increasing the thickness of TrA without increasing the thickness of IO and EO
