Myoelectric patterns observed from the CERSR array during standardized testing are sensitive in identifying healthy subjects from patients with internal disc derangement and a positive discogram. A positive CT discogram is defined as one following the Dallas discogram protocol with abnormal disc morphology and reproduction of symptoms
