What is a key preventive focus in Duchenne muscular dystrophy?

• A. Routine intense weight-bearing exercise without supervision
• B. Fracture and fall prevention
• C. Vitamin D and calcium supplementation
• D. Adrenal crisis avoidance

Answer: (B)

In Duchenne muscular dystrophy, progressive muscle weakness and reduced mobility raise the likelihood of falls, and long-term changes from corticosteroid use can weaken bones. Because fractures from even minor trauma can drastically affect function and independence, the central preventive focus is fracture and fall prevention. This includes maintaining bone health with appropriate vitamin D and calcium as part of overall care, plus safety measures, assistive devices, and supervised, progressive activity to preserve strength and balance. More intense, unsupervised weight-bearing exercise increases injury risk, and adrenal crisis avoidance is not the primary preventive target in this context.
