Gower's sign is a clinical feature observed in Duchenne muscular dystrophy.

• A. True
• B. False
• C. Rare
• D. Not observed

Answer: (A)

Gower's sign arises from proximal muscle weakness of the hip girdle and thigh extensors. When getting to a standing position from the floor, a patient uses the hands to push up along the legs to compensate for weak gluteal and thigh muscles. In Duchenne muscular dystrophy, progressive loss of dystrophin leads to marked proximal weakness in early childhood, so this sign is a classic, commonly observed feature. Therefore, stating that Gower's sign is seen in Duchenne muscular dystrophy is correct. It can occur in other proximal myopathies as well, but its presence in the right clinical setting strongly supports a dystrophin-related disorder.
