Spinal manipulative therapy (SMT) for low back pain (LBP)

Chiropractors are portal-of-entry providers that treat a variety of musculoskeletal conditions, the most common of which is LBP (low back pain)

• the most common treatment chiropractors employ is spinal manipulative therapy (SMT), also called chiropractic SMT (CSMT)
  • systematic reviews have found evidence supporting this treatment for acute LBP(1), chronic LBP (2) and radicular LBP (3)
    • among patients with acute low back pain, spinal manipulative therapy was associated with modest improvements in pain and function at up to 6 weeks, with transient minor musculoskeletal harms. However, heterogeneity in study results was large (1)
    • produces similar effects to recommended therapies for chronic low back pain but results in clinically better effects for short term improvement in function compared with non-recommended therapies, sham therapy, or when added as an adjuvant therapy (2)
  • evidence shows that receiving SMT for newly diagnosed LBP is associated with reduced odds of receiving a benzodiazepine prescription during follow-up (4)
