Final answer:
Symptoms of decreased anterior lumbar curve, increased posterior thoracic curve, rounded shoulders, sunken chest, and forward-tilted head are associated with disorders of the curvature of the spine.
Step-by-step explanation:
Decreased anterior lumbar curve, increased posterior thoracic curve, rounded shoulders, sunken chest, and forward-tilted head are symptoms associated with disorders of the curvature of the spine. These disorders include kyphosis (an excessive posterior curvature of the thoracic region) and lordosis (an excessive anterior curvature of the lumbar region). For example, rounded shoulders and a forward-tilted head can be signs of lordosis.
