The purpose of this project is to quantify 3-dimensional (3-D) cervical motion pattern changes that result from osteopathic manipulation treatment (OMT) in an experimental subject group diagnosed with somatic dysfunction. The kinematic data will include the entire 3-D motion trajectories of the head, resulting in range of motion (ROM) and angular data for the primary and secondary motions.

Primary Outcome Measures:
  • 3-D kinematic measurements of cervical motion [ Time Frame: 9/2009 to 8/2011 ]

Enrollment: 30
Study Start Date: September 2009
Study Completion Date: August 2011
Primary Completion Date: August 2011 (Final data collection date for primary outcome measure)
Control Group
Control group = functional symmetric cervical motion.
Experimental subject group
Experimental subject group = asymmetric cervical motion

Detailed Description:

Our primary hypothesis is that kinematic changes will be detected after OMT for motions in the primary direction of the passive diagnostic test motions (cervical side-bending right and left), as well as angular rotations (deviations) occurring around these motions. Our secondary hypothesis is that examination of the kinematic data will provide objective inter- and intra-examiner data to assess similarities/differences occurring during the passive clinical exam before and after OMT. Lastly, we hypothesize that significant differences in the kinematic patterns will result between the two subject groups.

This experiment is designed for the following clinical and biomechanical observations:

  • comparisons of diagnostic data between three osteopathic physicians,
  • comparisons of within-subject kinematic profiles pre- and post-treatment,
  • inter-examiner comparisons of kinematic motion paths occurring during diagnostic motions,
  • evaluate kinematic patterns between the two subject groups, and assess between group similarities/differences,
  • evaluate diagnostic and kinematic data relative to VAS, cervical disability, health status information, and SNF,
  • re-classify aspects of the kinematic data using a cluster (statistical) analysis procedure to compare with initial and secondary physician diagnostic data, and
  • to assess the stability of changes made by the OMT procedures and the kinematic response three days post-treatment.
