In which condition are rounded shoulders and a sunken chest a characteristic feature?

Scoliosis
Sway Back
Kyphosis
Flat Back

The correct answer is: Sway Back

The condition characterized by rounded shoulders and a sunken chest is kyphosis. In individuals with kyphosis, an abnormal curvature of the spine in the thoracic region leads to an exaggerated forward rounding of the back. This rounding often causes the shoulders to roll forward, which can result in the appearance of a sunken chest. While sway back also presents with some postural deviations, it typically involves an extended lower back with the pelvis tilted forward, which does not specifically manifest as rounded shoulders and a sunken chest. Scoliosis refers to a lateral curvature of the spine, and flat back posture entails a loss of the normal lumbar curve, presenting distinct postural characteristics not directly associated with rounded shoulders and a sunken chest. Therefore, kyphosis is the most accurate condition linked to these features.
