One of the most common causes of radiculopathy requiring neurosurgical treatment is a herniated disc. Magnetic resonance imaging (MRI) is still the main diagnostic approach for this lesion. However, MRI does not allow assessing the functional state of the root. Neurophysiological examination assesses the function of peripheral nervous system. These methods are used for differential diagnosis of causes of neurological symptoms and determine the level of the nerve root injury.
To assess the role of electromyography including paraspinal muscle mapping in diagnosis of radiculopathies following spine diseases.
We have analyzed literature data in the Scopus, Pubmed, and RSCI databases and selected 93 references for primary reviewing. Final analysis enrolled the manuscripts with a detailed description of neurophysiological examinations and data on sensitivity/specificity of these methods.
Needle electromyography (EMG) is the most informative neurophysiological method for diagnosis of radicular damage. Sensitivity of EMG is up to 90% for lumbosacral radiculopathy. Electromyography of the paraspinal muscles can be used in case of of cervical, thoracic and lumbar radiculopathy in addition to EMG of limb muscles. Therefore sensitivity increases to 100%. Diagnostic value of nerve conduction study (NCS) is low, and performing NCS without EMG is not useful.
In neurosurgical practice electrodiagnostic (EDX) should be performed for differential diagnosis of radiculopathy and peripheral nervous system lesions, to determine the level of radicular compression, and when physical examination does not correspond with neuroimaging or MRI is not possible to perform.
