Abstract
Objective: To determine electromyographic findings in Guillain-barré syndrome patients.
Setting and Duration Study: This is a descriptive cross-sectional study conducted in the Neuromedicine departments of tertiary care Hospital JPMC, from1st February 2020 to 30th July 2021.
Materials and Methods: GBS was diagnosed according to the diagnostic criteria from the National Institute of Neurological Disorders and Stroke (NINDS) in 1990. All patients gave consent to and underwent electromyographic assessment with a Keypoint evoked muscle potential equipment at admission and 2, 3, and 6 months post disease onset. The records of the patients were anonymized and deidentified before analysis.
Results: The Age range in this study was from 13 to 70 years with a mean age of 36.58±16.0 years. 63% of patients were of male gender and 37% of patients were female. The frequency of Electromyographic findings were acute demyelinating polyneuropathy in 73% of cases, acute sensorimotor axonal polyneuropathy 14% of cases, acute motor xonal polyneuropathy 12% of cases and acute sensory polyneuropathy 1% case.
Conclusion: The electromyography plays a role to diagnose GBS but along with this NCV and CSF analysis are also helpful in diagnosis and prognosis prediction.
