During the data collection process, other clinical categories could be defined for additional statistical analysis such as the loci of symptoms (i.e. lumbar, thoracic, cervical), the level of symptoms (lower, mid, or upper back) and the laterality of symptoms (left or right). Upon analysis of the laboratory and image findings (MRI, X-ray, blood tests) other anatomic findings or variations such as degenerative disc disease, size of possible disc protrusions, Sedimentation Rate or CPK values, Schmorld’s nodes, etc. may also be discussed.
