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 .

Course and prognosis of recovery for chronic non-specific low back pain: design, therapy program and baseline data of a prospective cohort study
Background There has been increasing focus on factors predicting the development of chronic musculoskeletal disorders . For patients already experiencing chronic non-specific low back pain it is also relevant to investigate which prognostic factors predict recovery . We present the design of a cohort study that aims to determine the course and prognostic factors for recovery in patients with chronic non-specific low back pain . Methods / Design All participating patients were recruited ( Jan 2003-Dec 2008 ) from the same rehabilitation centre and were evaluated by means of ( postal ) question naires and physical examinations at baseline , during the 2-month therapy program , and at 5 and 12 months after start of therapy . The therapy protocol at the rehabilitation centre used a bio-psychosocial approach to stimulate patients to adopt adequate ( movement ) behaviour aim ed at physical and functional recovery . The program is part of regular care and consists of 16 sessions of 3 hours each , over an 8-week period ( in total 48 hours ) , followed by a 3-month self-management program . The primary outcomes are low back pain intensity , disability , quality of life , patient 's global perceived effect of recovery , and participation in work . Baseline characteristics include information on socio-demographics , low back pain , employment status , and additional clinical items status such as fatigue , duration of activities , and fear of kinesiophobia . Prognostic variables are determined for recovery at short-term ( 5 months ) and long-term ( 12 months ) follow-up after start of therapy . Discussion In a routine clinical setting it is important to provide patients suffering from chronic non-specific low back pain with adequate information about the prognosis of their complaint
