Introduction: Guillain Barre´ Syndrome (GBS) is an acute immune mediated de-mylelinating poly-neuropathy. Worldwide, the incidence of GBS is 0.6-4.0 per 100,000. The disease is very variable in severity that recovers within weeks, due to widespread paralysis of muscles and loss of sensation. Weakness is prominent in leg muscles as compared to arms. In Guillain-Barré syndrome (GBS), foot drop may be seen within the first few days of the illness and may persist for months which are evaluated using Electrodiagnostic method.
Objectives: objective of this study was to find out the Nerve ConductionVelocity of common peroneal nerve of the affected lower extremities in participants with Guillain Barre Syndrome.
Methods: Thirty participants between the ages of 25- 50 years with the clinical diagnosis of Guillain Barre Syndrome with 1- 3month duration. Nerve Conduction Velocity of the Common Peroneal Nerve was studied in participant’s right and left lower limbs. Outcome measures used in this study was distal latency, Motor NCV, Sensory NCV, CMAP and SNAP amplitude.
Results: The result of the study suggests that there is symmetrical involvement in both lower limbs in Sub- Acute Guillain Barre Syndrome. This study showed that there was prolonged latency, reduced amplitude & reduced motor nerve conduction velocity and reduced latency, increased amplitude & reduced Sensory Nerve Conduction Velocity of common peroneal nerve in both lower limbs
Conclusion: The present study concluded that there is symmetrical involvement and both sensory as well as motor nerve conduction velocity are affected in sub-acute stage of Guillain Barre Syndrome.
