Background: There is no previous study examining the immediate effect of manipulation on segmental thoracic stiffness and functional kinematics in chronic neck pain (CNP) or test-retest reliability of a rolling-indentation spinal stiffness measurement (RISSM) device for thoracic spine.
Purpose: To establish the test-retest reliability of thoracic spine stiffness measurement in able-bodied and CNP individuals and to investigate the immediate effect of thoracic manipulation on spinal kinematics during functional tasks and segmental stiffness in CNP population.
Methods: Thirty-four CNP and seventeen asymptomatic participants underwent the test-retest reliability of RISSM on thoracic spine in prone lying position. Pain intensity, segmental stiffness and kinematics of the thoracic spine were assessed by Numeric Pain Rating Scale, VerteTrack (RISSM device) and DIERS Formetric 4D tomography respectively, before and after thoracic manipulation in experimental (n=17) and control groups (n=17) of CNP participants.
Results: Excellent reliability was found for segmental thoracic spine stiffness measurement in CNP (ICC3,1=0.945-0.983) and asymptomatic (ICC3,1=0.795-0.961) groups. Significant between-groups difference (p<0.001) was observed for neck pain intensity, but not spinal stiffness (p>0.05) or functional kinematics of thoracic spine (p>0.05) in CNP participants, post-intervention. The experimental group (p<0.001) but not control group (p>0.05) showed significant reduction in neck pain intensity after manipulation (effect size: 1.22-1.81).
Conclusion: Excellent test-retest reliability for thoracic spine using RISSM device was found. Thoracic manipulation could only reduce the neck pain intensity without any associated modulation of thoracic stiffness and functional kinematics in CNP participants.
Implications: Further study on pain-relief mechanism of thoracic manipulation on CNP population is warranted.
