Association of Spinal Manipulative Therapy With Changes in Cervical Motion Segment Interactions in Patients With Neck Pain: An Observational Study With Matched Asymptomatic Controls

AbstractObjective The objectives of this study were to determine (1) if maximal intervertebral range motion (IV-RoMmax) and laxity interactions exist in the cervical spine during flexion, (2) there are differences IV-RoMmax or parameters between baseline follow-up both patients with neck pain asymptomatic controls, (3) is an effect on IV-RoMmax/laxity relationships after spinal manipulative therapy. Methods Twenty-nine subacute chronic 33 controls imaged flexion extension, pre post a course chiropractic manipulation (patient group only), using standardized quantitative fluoroscopy acquisition protocol. Results Significant correlations IV-RoMs found pain–free populations at follow-up. Positive C2-C3 C3-C4 C4-C5 C5-C6 IV-RoM populations. A negative correlation was patient C1-C2 C5-C6, but not also for segmental laxity, only only. Conclusion Distinct intraregional many which present groups follow-up, suggestive normal kinematic behaviors. Changes unique may be indicative change regional kinematics resulting from intervention. Spinal therapy have therapeutic by influencing level.
