Objective
To assess factors affecting electrophysiological changes in the peripheral nervous system below the neurologic level of injury (NLI) in patients with subacute spinal cord injury (SCI).
Design
Retrospective observational study.
Setting
An inpatient rehabilitation center of a university hospital.
Participants
Through reviewing the medical records of 151 subjects with SCI, 42 without any other disease inducing peripheral neurologic abnormalities were included. They were classified into 2 groups, with or without denervation potentials in electromyography (EMG) below NLI.
Intervention
Not applicable.
Main Outcome Measures
Demographics and clinical characteristics including NLI, American Spinal Injury Association Impairment Scale (AIS), and Lower Extremity Motor Score were compared. Results of electrophysiological study including nerve conduction study, somatosensory-evoked potential (SSEP), and motor-evoked potential (MEP) were compared.
Results
Denervation potentials in EMG below NLI were observed in 20 subjects, and 10 of them were AIS A or B, but there was none in subjects without denervation potentials (P<.001 the lower extremity motor score was in group with denervation potentials than of opposite analysis electrophysiological study patients showed a higher proportion no response without vs peroneal nerve conduction tibial ssep mep p respectively additionally greater axonal loss based on decrease amplitude delayed latency observed>
Conclusion
Among subjects with subacute SCI, cases of peripheral nervous dysfunction below the injury site occur, possibly associated with the severity of SCI. |
