What are the functional mechanisms of altered movement patterns during trunk flexion tasks? The need for further sub-classification: A systematic review

Background: Sub-classification is recommended in non specific low back pain (LBP). Although there are different schools of thought, one common sub-classification for LBP is to sub-classify patients based on their movement patterns into flexion, extension and rotation. The foundation of this hypothesis that a sub-group of subjects with low back pain (LBP) will use end range movements of the lumbar spine more routinely and have increased loading on soft issues. The poor motor program is considered the underlying mechanism, however this does not consider why the central nervous system (CNS) chooses to move the lumbar spine differently in LBP, presumably in a manner that increases soft tissue loading and may aggravate symptoms.
