[Diagnostic and prognostic value of diaphragmatic electromyography and somatosensory evoked potentials in cervical spine and spinal cord injuries].
SEP contribution to diagnosis is interesting but limited to hardly examined complete syndromes in an emergency care unit. The predictive value of SEP is high if electrophysiological data are correlated the 10th. day with the clinical status. A good prognostic value is shown when the clinical posterior column and pyramidal tract dysfunctions are equal in intensity and distribution, i.e. in complete syndromes or central spinal cord syndromes or Brown-Sequard's ones. However, not any correlation exists in cases of anterior spinal cord syndromes. Dg.EMG. is an easy, atraumatic useful tool for the clinician. It must be a systematic approach of the brain stem and cervical spinal cord phrenic centers vitality that may be involved by the trauma. When a respiratory deficiency occurs, it allows the diagnosis of a "peripheral" or "neurological" etiology. Its high prognostic value for m tor diaphragmatic function (increase or decrease) must be discussed before any therapeutic decision.
