Electrodiagnosis of neck pain

Dr. Kraft and Dr. Han have provided an up-to-date perspective on the various electrodiagnostic procedures (electromyelography, nerve conduction studies, and somatosensory evoked potentials) that can be used in the diagnosis of cervical disorders and related neurologic dysfunctions. On the one hand, Dr. Kraft and Dr. Han cover detailed descriptions of the various methodologies, and on the other, they explain the limitations of these procedures and their potential for inappropriate use. The article provides definitive guidance about when and how electrodiagnosis can play a critical role in the diagnosis and treatment of cervical and upper limb disorders. –RLS Evaluation of a patient with neck and back pain is challenging because of the multitude of neurologic, musculoskeletal, and psychologic factors that may contribute to the pathology and symptoms [1,2]. A diagnosis can often be reached by careful history and examination complemented by appropriate use of radiologic and physiologic tests [3–5]. Electrodiagnostic study is the only means by which physiologic function of nerves can be tested. It can be used to confirm a clinical suspicion of neurologic disorder, to rule out other, more distal neuropathies, or to verify subjective muscle weakness in patients with pain inhibition or lack of cooperation
