Which of the following is the main outcome measure for Duchenne muscular dystrophy?

The Vignos Functional Rating Scale is indeed the main outcome measure for assessing Duchenne muscular dystrophy (DMD). This scale is specifically designed to evaluate the functional capabilities of individuals with DMD, focusing on their ability to perform various motor activities and daily tasks. The scale helps clinicians track the progression of the disease and the impact it has on the physical functioning of affected children.

Utilizing the Vignos scale allows for a standardized assessment that can be compared across different populations and clinical trials. It provides a clear framework for understanding the functional status of individuals at different stages of the disease, making it an essential tool for both clinical practice and research.
