What age do individuals with Duchenne's muscular dystrophy often require a wheelchair?

• A. By age 12
• B. By age 6
• C. By age 9
• D. By age 15

Answer: (C)

Individuals with Duchenne's muscular dystrophy (DMD) typically experience progressive muscle weakness, which becomes increasingly apparent during early childhood. Most children with DMD maintain some ability to walk until around the age of 6, but as the condition progresses, they usually require a wheelchair for mobility by approximately age 9. This transition occurs because the continued deterioration of muscle strength, particularly in the legs, impedes independent ambulation and the ability to keep up with developmental milestones common in peers. The age of 9 serves as a general milestone when many children may no longer be able to walk long distances or participate in physical activities that they once enjoyed. It is important for families and caregivers to understand this timeline to prepare for mobility needs and interventions that can enhance quality of life as children with DMD continue to grow and develop.
