A previous review concluded that postural sway is increased in patients with low
back pain (LBP). However, more detailed analysis of the literature shows that
postural deficit may be dependent on experimental conditions in which patients
with LBP have been assessed. The research question to be answered in this review
was: "Is there any difference in postural sway between subjects with and without
LBP across several sensory manipulation conditions?".
A literature search in
Pubmed, Scopus, Embase and PsychInfo was performed followed by hand search and
contact with authors. Studies investigating postural sway during bipedal stance
without applying external forces in patients with specific and non-specific LBP
compared to healthy controls were included. Twenty three articles fulfilled the
eligibility criteria. Most studies reported an increased postural sway in LBP, or
no effect of LBP on postural sway. In a minority of studies, a decreased sway was
found in LBP patients. There were no systematic differences between studies
finding an effect and those reporting no effect of LBP.
The proportion of studies
finding between-group differences did not increase with increased complexity of
sensory manipulations. Potential factors that may have caused inconsistencies in
the literature are discussed in this systematic review.
