Evaluation of lumbar segmental motion using ultrasound imaging following common joint mobilization techniques

Significant increases were observed in L4/5 flexion immediately following joint mobilization regardless of mobilization group, with significant statistical interactions observed between segmental motion, sex, and/or Beighton risk. This is the first investigation to demonstrate the value of USI for quantifying lumbar segmental motion following joint mobilization. Quantifying lumbar segmental motion helps clarify the underlying mechanisms of manual therapy. Future studies should include patients with low back pain.
