Variability of Intradiscal Pressure During Cervical Spine Posterior-Anterior Mobilization: A Cadaveric Investigation
Objectives
The purpose of this study was to investigate in cadaveric specimens the reliability of measuring cervical intradiscal pressure (CIDP) and if posterior-anterior (PA) mobilizations targeting the cervical spine were associated with CIDP changes.
Methods
Cervical PA mobilizations were performed on the spinous processes of 7 (3 men, 4 women) cadaveric specimens using a servo-controlled linear actuator to provide 25N and 45N forces. CIDP measurements were performed at C4-5, C5-6, C6-7, and C7-T1 intervertebral discs (IVDs) using a fiberoptic catheter system that recorded CIDP for each IVD cervical segment. To assess CIDP measurement reliability, the intraclass correlation coefficient (ICC [3,k]) was calculated. Repeated measures Friedman analysis of variance assessed effect of cervical mobilizations on CIDP for before, during, and immediately after mobilization at 25N and 45N forces for each cervical IVD segment.
Results
All CIDP measurements demonstrated excellent reliability (ICC >0.98). During the 25N mobilizations, the median CIDP varied from -0.12 to 0.91 (interquartile range, 5.22-5.36), while for 45N mobilizations the median ranged from -0.94 to 1.21 (interquartile range, -7.74 to 43.49). These changes were not statistically significant (P > .40) during 25N and 45N PA mobilizations, with the exception of C5-6 CIDP at 25N and 45N (P = .05 and .018, respectively).
Conclusion
There was high CIDP variability between cadavers during and after mobilization. Mobilizations of 1 cervical vertebra resulted in both CIDP increase or decrease at adjacent and remote cervical IVD segments that were not consistent. Cervical PA mobilizations produced variable CIDP changes at adjacent and remote cervical segments in cadavers.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
