Evidence synthesis showed limited evidence supporting poor baseline transversus abdominis contraction thickness ratio as a treatment effect modifier favoring motor control exercise .
Limited evidence supported that high baseline transversus abdominis lateral slide was associated with higher pain intensity after various exercise interventions at 1-year follow-up .
However , there was limited evidence for the absence of relation between the contraction thickness ratio of transversus abdominis or anticipatory onset of lateral abdominal muscles at baseline and the short- or long-term LBP intensity after exercise interventions .
There was conflicting evidence for a relation between baseline percent thickness change of lumbar multifidus during contraction and the clinical outcomes of patients after various conservative treatments .
Although individual reports suggest that baseline morphometry or activity of transversus abdominis or lumbar multifidus predict clinical outcome of low back pain ( LBP ) , a related systematic review is unavailable .

Trunk muscle stabilization training plus general exercise versus general exercise only: randomized controlled trial of patients with recurrent low back pain.
BACKGROUND AND PURPOSE The purpose of this r and omized controlled trial was to examine the usefulness of the addition of specific stabilization exercises to a general back and abdominal muscle exercise approach for patients with subacute or chronic nonspecific back pain by comparing a specific muscle stabilization-enhanced general exercise approach with a general exercise-only approach . SUBJECTS Fifty-five patients with recurrent , nonspecific back pain ( stabilization-enhanced exercise group : n=29 , general exercise-only group : n=26 ) and no clinical signs suggesting spinal instability were recruited . METHODS Both groups received an 8-week exercise intervention and written advice ( The Back Book ) . Outcome was based on self-reported pain ( Short-Form McGill Pain Question naire ) , disability ( Rol and -Morris Disability Question naire ) , and cognitive status ( Pain Self-Efficacy Question naire , Tampa Scale of Kinesiophobia , Pain Locus of Control Scale ) measured immediately before and after intervention and 3 months after the end of the intervention period . RESULTS Outcome measures for both groups improved . Furthermore , self-reported disability improved more in the general exercise-only group immediately after intervention but not at the 3-month follow-up . There were generally no differences between the 2 exercise approaches for any of the other outcomes . DISCUSSION AND CONCLUSION A general exercise program reduced disability in the short term to a greater extent than a stabilization-enhanced exercise approach in patients with recurrent nonspecific low back pain . Stabilization exercises do not appear to provide additional benefit to patients with subacute or chronic low back pain who have no clinical signs suggesting the presence of spinal instability
