The primary objective of this study was to determine the acceleration characteristics of spinal manipulative therapy (SMT) and whether patient anthropometric parameters correlated with the SMT kinematic parameters. For this, a wireless tri-axial accelerometer was taped to the dorsum of a clinician's hand to record the accelerations generated during clinical treatment of 95 symptomatic patients. Peak acceleration magnitudes differed significantly between spinal levels (p<0.0001; lumbar > cervical > thoracic = sacroiliac). The latencies of these peaks were also significantly different (p<0.0001; lumbar < cervical = thoracic < sacroiliac). Within a given spinal level, acceleration amplitudes varied over a wide range with temporal parameters remaining relatively constant. Overall, anthropometric parameters were poorly correlated with SMT parameters. In summary, distinct acceleration amplitudes were observed across spinal levels with relatively constant temporal factors. Thus, clinicians appear to vary the magnitude rather than the duration of the SMT thrust.ii Acknowledgements

“…[11][12][13] Although these studies have used well-controlled moments of force to induce movements and have even attempted to simulate manual mobilizing techniques, thus eliciting the possible specific effects of such interventions, 14 the authors did not provide information on the reproducibility of the investigated kinematic aspects. The quantification of kinematics is often limited to the description of ranges of motion and of the direction of the coupled motion component with reference to the main motion.…”

“…So far, little evidence has been presented to help therapists understand what really happens during manual mobilization at the level of the cervical spine and especially at the alanto-axial joint, which is generally considered a vulnerable region for manipulative therapy. [14][15][16][17][18] Most therapeutic strategies are built on mechanical concepts of motion coupling derived from general anatomical joint models and they often ignore anatomical variability. Moreover, the specific effects of therapist specific variation in techniques have been ignored.…”

The reproducibility of the three-dimensional (3D) kinematic aspects of motion coupling patterns during manual mobilizing techniques is still a debatable matter. The present in vitro study analysed segmental 3D motion of the atlanto-axial joint during manual axial rotation mobilization. Twenty fresh frozen human cervical specimens were studied in a test-retest situation with two examiners. The specimens were manually mobilized using three different techniques: (1) a regional mobilization technique of the cervical spine; (2) a segmental mobilization technique of the atlas with manual fixation of the axis; and (3) a segmental mobilization of the atlas on the axis applying a locking technique. Segmental atlanto-axial kinematics was registered with a Zebris CMS-20 ultrasound-based tracking system. The Euclidian norm was used as a representation of overall 3D motion. The results indicated good reproducibility (mean intraclass correlation coefficient, ICC: 0.87). Intraobserver reproducibility was slightly higher (mean ICC: 0.91; range: 0.76-0.99) than interobserver reproducibility (mean ICC: 0.85; range: 0.56-0.98) (P , 0.05). The total range of motion expressed as the Euclidean norm of 3D motion components was a parameter with good reproducibility in the study of segmental kinematics of manual atlanto-axial mobilization. Although previous studies have demonstrated poor inter-rater reliability of manual examination and mobilization of segmental motion components, the results of the present study shed a new and more positive light on the reproducibility of techniques for manual mobilization of the upper cervical spine.
