274th ENMC international workshop: recommendations for optimizing bone strength in neuromuscular disorders. Hoofddorp, The Netherlands, 19-21 January 2024.

The 274th ENMC workshop for optimizing bone strength in neuromuscular disorders (NMDs) was held on January 19-21, 2024. The group of participants included experts in the fields of bone health and neuromuscular medicine along with the patient voice. Bone strength represents a crucial aspect of the management of pediatric and adult patients with NMDs. Bone strength may be compromised due to different pathophysiologic mechanisms, including disrupted bone-muscle "cross-talk", loss of biomechanical loading, nutritional insufficiency, inadequate weight-bearing physical activity, muscle weakness and/or immobility, and drug treatment. While for Duchenne muscular dystrophy recommendations for evaluation and treatment of bone strength have been published, evidence on bone strength in other hereditary and acquired NMDs is scarce. Enhanced knowledge is needed to understand the development and maintenance of bone strength in patients with NMDs. This workshop aimed to develop a strategy to improve bone strength and thus prevent fractures in patients with NMDs.
