Mean age in which kids with DMD become dependent on electric wheelchair is how old?

Explanation:
In Duchenne muscular dystrophy, progressive proximal weakness gradually reduces a child’s ability to walk and then to sustain manual mobility as trunk and arm strength decline. As energy demands outweigh capacity, many transition from manual propulsion to a powered (electric) wheelchair to maintain independence over longer distances. The average age at which this shift to electric wheelchair dependence occurs is about 14.6 years. This figure represents the typical mid-teen transition in the disease course, though there is variation—some children need powered mobility earlier, others later.
