What this trial studies

This observational study aims to explore the natural history and muscle fatigability of patients with congenital myopathies, specifically Central Core Disease, Multi-Minicore Disease, Nemaline Myopathy, and Centronuclear Myopathy. Over a period of 24 months, participants will undergo assessments through a prospective cohort study with multiple visits to gather detailed information on disease progression and identify sensitive clinical outcome measures. The study will also investigate the severity of muscle fatigability, a common symptom reported by patients, to better understand its impact on their daily lives. The research is being conducted at Radboud University Medical Center and UMC Utrecht in the Netherlands.

Who should consider this trial

Good fit: Ideal candidates include Dutch-speaking individuals aged 2 years and older with genetically confirmed congenital myopathy.

Not a fit: Patients with other neuromuscular, psychiatric, or neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the progression and management of congenital myopathies, potentially leading to improved treatment strategies.

How similar studies have performed: While there have been some trials related to congenital myopathies, this specific focus on muscle fatigability and natural history is relatively novel.
