N2 - Background: The Bone and Joint Decade 2000e2010 Task Force on Neck Pain and its Associated Disorders (BJD) indicates that there is a significant shortage of scientific research to support manual therapies in diagnosis and treatment, specifically for the cervical region. Objective: The purpose of this research was to quantify motions associated with the palpatory diagnostic procedure of cervical lateral flexion using three-dimensional (3-D) motion capture techniques. Further, these data were examined for relationships with the clinical diagnosis. Design setting: 3-D kinematic data were examined for relationships to a palpatory diagnostic test of cervical lateral flexion. Methods: A five-camera video based motion system was used to collect 3-D data during passive cervical lateral flexion. These data were then used to compute head movements relative to the thorax. Statistical analysis of the angular data included non-parametric tests, binary logistical regression and cluster analysis. Subjects: Eighty-five subjects were classified into two groups: asymptomatic (n ¼ 76) with a VAS < 4, and symptomatic (reporting neck pain on the day of the experiment) with a VAS 4/10 (n ¼ 9). Only asymptomatic subjects with symmetrical passive cervical lateral flexions as determined by the blinded consensus of two experienced and trained examiners were included in the study (n ¼ 10). Results: Symptomatic subjects exhibited significantly greater kinematic differences between repeat trials of the diagnostic test as compared to asymptomatic subjects. The data also suggests a trial dependent “warm up” effect. Further, the cluster analysis of the difference measure showed the potential of kinematic analysis to discern between the two subject groups. Conclusions: Results from this study demonstrate the ability to generate objective data that can be related to a manual medicine diagnostic test. This methodological approach may serve as a foundation for additional kinematic studies of manual medicine techniques, as well supporting work for documenting treatment outcomes and to assisting in teaching and training clinicians.
