Abstract
AbstractBackground and ObjectivesThe role of spinal movement alterations in low back pain (LBP) remains unclear. This systematic review and meta‐analyses examined the relationships between spinal amplitude of movement, disability and pain intensity in patients with LBP.Databases and Data TreatmentWe searched PubMed, CINAHL, Embase, Pedro and Web of Science for relevant articles until 14th March 2023. Risk of bias was assessed with the Quality in Prognostic Studies Tool. We analysed the relationships between amplitude of movement, disability and pain intensity with standard correlational meta‐analyses and meta‐analytic structural equation modelling (MASEM) in cross‐sectional and longitudinal data.ResultsA total of 106 studies (9001 participants) were included. In cross‐sectional data, larger amplitude of movement was associated with lower disability (pooled coefficient: −0.25, 95% confidence interval: [−0.29 to −0.21]; 69/5899 studies/participants) and pain intensity (−0.13, [−0.17 to −0.09]; 74/5806). An increase in amplitude of movement was associated with a decrease in disability (−0.23, [−0.31 to −0.15]; 33/2437) and pain intensity (−0.25, [−0.33 to −0.17]; 38/2172) in longitudinal data. MASEM revealed similar results and, in addition, showed that amplitude of movement had a very small influence on the pain intensity–disability relationship.ConclusionsThese results showed a significant but small association between amplitude of movement and disability or pain intensity. Moreover, they demonstrated a direct association between an increase in amplitude of movement and a decrease in pain intensity or disability, supporting interventions aiming to reduce protective spinal movements in patients with LBP.SignificanceThe large meta‐analyses performed in this work revealed an association between reductions in spinal amplitude of movement and increased levels of disability and pain intensity in people with LBP. Moreover, it highlighted that LBP recovery is associated with a reduction in protective motor behaviour (increased amplitude of movement), supporting the inclusion of spinal movement in the biopsychosocial understanding and management of LBP.
