Congenital myasthenic syndrome diagnosed best with repetitive stimulation and jitter analysis

Key clinical point: Congenital myasthenic syndrome requires both repetitive stimulation and jitter analysis for accurate diagnosis.

Major finding: Use of jitter analysis without repetitive stimulation for diagnosing congenital myasthenic syndrome results in 86.5% accuracy.

Study details: The findings are based on comparison of jitter analysis and repetitive stimulation in 55 patients with myopathies or myasthenia and 14 controls.

Disclosures: The research used no external funding, and Dr. Marques Caldas had no disclosures.
