title: [Changes of segmental motion after spinal manipulation in patients with lumbar intervertebral disc protrusion].
abstract: OBJECTIVE
  To explore the effect of manipulation on segmental motion of lumbar vertebra and the clinical significance before and after treatment, and evaluation with charge couple device (CCD) measurement system.
  
  
  METHODS
  CCD and dynamic radiography were conducted in 30 patients before and after treated by manipulation or other conservative therapy, analysis and comparisons in segmental motion ranges of flexion-extension and lateral bending, correlation between data of CCD system and radiography as well as characteristics of lumbar vertebral function recovery after manipulation were performed.
  
  
  RESULTS
  Certain correlation between data of CCD and radiography was shown by linear correlation test (r = 0.42-0.72, P < 0.05-0.01). Paired t test showed that the lower lumbar segmental flexion-extension function was significantly recovered (t = 2.26-2.61, P < 0.05-0.01) after manipulation, but the recovery on other segments was insignificant.
  
  
  CONCLUSIONS
  The special designed CCD system is of important clinical significance in assessing segmental lumbar vertebral function. Lower lumbar vertebral flexion-extention functional state is a crucial criterium for evaluation of manipulative therapy in lumbar intervertebral disc protrusion.
