Abstract

Context: Transverse abdominis (TrA) activation dysfunction has been linked to low back pain (LBP). Several exercise recommendations have been made regarding training the TrA; specifically the abdominal drawing in maneuver (ADIM). Biofeedback tools and verbal cueing have become an important part of educating patients of proper activation. Therefore, the purpose of this study was to determine the effectiveness of different biofeedback tools on TrA activation in a single intervention session. Design: Single-blinded randomized controlled trial. Setting: Laboratory. Participants: Fifty asymptomatic individuals: 27 females and 23 males (age: 22.2 ± 3.4 years, height:, weight: 73.1 ± 11.7 Kg ). Interventions: Each subject was randomly assigned to one of four biofeedback groups: ultrasound (US), pressure biofeedback unit (PBU), ultrasound and pressure biofeedback unit (US+PBU), and the control group. Three baseline ADIMs were performed and captured via ultrasound imaging. Then, the subject was allowed to view the biofeedback assigned to them and performed ten ADIMs. After, the biofeedback was removed and three final images were taken of the TrA. Results: No significant findings were found for any of the post-intervention activation measurements between groups (p =.501). There was also no significant difference between baseline and post-intervention TrA activation ratios (p=.207) Conclusions: In a young, healthy population there appear to be no significant changes in TrA activation among various biofeedback tools
