Summary
Repeat electromyography (EMG) in children with polymyositis or dermatomyositis reveals persistent myogenic signs even after clinical recovery. These electrical anomalies are the last to resolve, indicating EMG
Area of Science:
- Neurology
- Pediatrics
- Rheumatology
Context:
- Polymyositis and dermatomyositis are inflammatory myopathies affecting children.
- Electromyography (EMG) is a diagnostic tool used to assess muscle and nerve disorders.
Purpose:
- To report findings of repeat electromyography (EMG) in pediatric polymyositis and dermatomyositis.
- To emphasize the diagnostic contribution of stimulodetection in primary muscle disease.
- To evaluate the long-term changes in EMG findings during disease course and recovery.
Summary:
- EMG demonstrated myogenic signs in all 15 children with polymyositis or dermatomyositis at initial examination.
- Electrical anomalies were widespread from the onset and persisted long after clinical recovery in 12 patients.
- EMG abnormalities were the last to resolve, with normalization occurring after prolonged recovery and reappearing upon relapse.
Impact:
- Highlights the prolonged presence of EMG abnormalities in inflammatory myopathies, even after clinical improvement.
- Underscores the utility of EMG, particularly stimulodetection, in diagnosing and monitoring pediatric inflammatory myopathies.
- Provides insights into the natural history of EMG findings in relation to disease activity and recovery in children.
