A main challenge regarding the spine is determining its rotational axis. Previous research on this topic has yielded contradictory results because of the anatomic and functional complexity of the spine. The objective of this study was to determine the apparent axial center of rotation by developing and validating a new method. With a better understanding of spine biomechanics, the future of treatment for back pain and instability, particularly in the lower segments, may need to be reexamined. Medical or surgical interventions for the spine could also potentially be improved through a better understanding of the spinal center of rotation.
