Childhood Myositis Assessment Scale

The Childhood Myositis Assessment Scale (CMAS) is a tool doctors use to evaluate muscle strength and function in children with myositis, a condition that causes muscle inflammation and weakness. The test involves a series of physical tasks, such as raising arms, holding breath, or climbing stairs, to measure how well muscles are working. By regularly assessing these abilities, healthcare providers can track disease progress, determine the effectiveness of treatments, and adjust care plans to help children maintain as much strength and activity as possible.
