The Kinetic and Kinematic Effect of Varying the Instantaneous Axis of Rotation of the Cervical Spine

Client: Robert McLain M.D. / Cleveland Clinic

Services Provided: Experiment Design, Robotic Spine Joint Testing, Data Analysis, Manuscript Preparation

When considering movements of the cervical spine, the global (cervical spine as a whole) instantaneous axis of rotation (IAR) as well as the IAR for each adjacent set of vertebral bodies will vary depending on the particular activity being executed. For example, two ways to flex the neck include a chin tuck, or a long reach to look down over something. In each case the global IAR will vary along with the associated kinetics and kinematics of the spine. The effect on multi-level kinematics, along with any associated increase in shear loads, were measured when comparing global IAR placed at either the C3-C4 level, or the C6-C7 level.
