People living with Duchenne who are not treated with corticosteroids have a 90 percent chance of developing progressive scoliosis (a sideways curvature of the spine that gets worse over time). Daily steroid treatment has been shown to reduce the risk of scoliosis, or to significantly delay its onset. Paying attention to your posture and positioning is critical for preventing scoliosis. Continued assessment of your spine throughout your lifespan is essential.
