Stages of Duchenne

Although the progression and severity of each case is different, there are four generally recognized stages of Duchenne. Consider the ages attributed to each stage as approximate.

Physical decline in Duchenne is first apparent when boys are very young. Weakness is most obvious in large muscles (such as legs), and progresses to small muscles (such as hands) over time.

Let's seize this moment.


There has never been so much momentum in the Duchenne community. Help us keep moving forward by donating to fund CRISPR/Cas9 gene‑editing technology. Every gift to PPMD is being doubled until we raise $250,000—but we have to reach this goal by 12/31!
