Do Participants with Low Back Pain who Respond to Spinal Manipulative Therapy Differ Biomechanically From Nonresponders, Untreated Controls or Asymptomatic Controls?

Chiro.Org Blog: Our results demonstrate that those reporting post-SMT improvement in disability have coherent changes in multiple, objective measures of spinal biomechanics. This same coherence does not exist for asymptomatic controls or no-treatment symptomatic controls. Our data further support a differential effect of SMT on a specific constellation of biomechanical outcomes that are not responsive in all patients with LBP. This work provides a foundation from which to investigate the heterogeneous nature of LBP, the mechanisms underlying differential therapeutic response, and the biomechanical characteristics defining the responders at baseline.

How Can Latent Trajectories of Back Pain be Translated into Defined Subgroups?

Chiro.Org Blog: This study was the first to demonstrate that suggested definitions of LBP trajectory subgroups can be readily applied to individuals’ observed data resulting in subgroups that match well with LCA-derived trajectory patterns. We suggest that the number of trajectory subgroups can be reduced by merging some subgroups with infrequent and mild LBP. Further, we suggest that minor fluctuations in pain intensity might be conceptualised as ‘ongoing LBP’. Lastly, we found clear support for distinguishing between fluctuating and episodic LBP.
