Overview

Randomized trial evaluates effects of spinal manipulation on pain and disability in low back pain.

Key Points

  • The study aims to determine if spinal manipulation leads to measurable changes in lumbar motion and short-term clinical outcomes compared to a sham intervention.
  • Forty-four adults with low back pain were randomly assigned to receive either lumbar spinal manipulation or a sham intervention.
  • Segmental lumbar motion was assessed using ultrasound imaging by measuring distances between adjacent lumbar spinous processes.
  • Outcomes such as pain, trunk flexion, and disability were assessed before and after the intervention using validated scales.
  • No significant change in ultrasound-assessed lumbar motion was observed between groups (F (1,42)=0.001, p = 0.972).
  • Significant reduction in pain intensity was found in the SM group (F (2,84) = 4.39, p = 0.015).
  • Disability improved more in the SM group compared to sham intervention (F (1,42) = 12.38, p = 0.001).
