Abstract

Aim. The dynamic stability of the low back region is governed by the core musculature, namely the transverse abdominis (TrA) and multifidus. Most rehabilitation professionals believe that selective activation training of the TrA can decrease symptoms in individuals with non-specific low back pain (NSLBP). In this study we have aimed to analyze the effects of varied biofeedback training of the transverse abdominis muscle on the muscle thickness in LBP individuals.

Materials & Methods. Thirty-four LBP individuals were randomly allotted to varied biofeedback training and core muscle exercise groups for three weeks. The transverse abdominis muscle thickness at rest and during the abdominal drawing-in maneuver (ADIM) and the TrA activation ratio were measured as outcomes using ultrasonography.

Results. Varied biofeedback training for three weeks resulted in a significant increase in the thickness (cm) of the transverse abdominis at rest (0.41 ± 0.06) and abdominal drawing-in maneuver (0.54 ± 0.05). There was no significant change in the transverse abdominis contraction ratio between the groups.

Conclusion. Varied biofeedback training of the transverse abdominis was found to be effective in improving the thickness of the transverse abdominis in the treatment of non-specific lower back pain. This above finding may have positive clinical implications in individuals with non-specific lower back pain.
