Definition & Meaning of "facioscapulohumeral muscular dystrophy"

What is "facioscapulohumeral muscular dystrophy"?

Facioscapulohumeral muscular dystrophy (FSHD) is a genetic disorder that affects the muscles of the face, shoulders, and upper arms. It is characterized by progressive weakness and wasting of these muscles, leading to difficulty with tasks such as lifting the arms, smiling, or closing the eyes tightly. FSHD usually begins in adolescence or early adulthood and can vary widely in intensity between individuals. It is caused by changes in genes that are involved in muscle function. Treatment for FSHD focuses on managing symptoms and improving quality of life. This may include physical therapy to strengthen muscles and maintain flexibility, assistive devices such as braces or supports, and medications to address specific symptoms such as pain or fatigue. While there is currently no cure for FSHD, ongoing research may lead to new treatments in the future.
