What condition is commonly referred to as "swayback"?

The condition commonly referred to as "swayback" is indeed lordosis. Lordosis is characterized by an excessive inward curvature of the spine, particularly in the lower back (lumbar region). This condition can lead to a protruding abdomen and buttocks, giving the appearance of a sway in the back, which is why it's colloquially known as "swayback."

Understanding lordosis involves recognizing its potential causes, which may include factors such as muscle imbalances, obesity, or certain developmental conditions. It's essential in the context of overall spinal health, as excessive lordosis can lead to discomfort, pain, and functional limitations if not addressed.

Scoliosis, on the other hand, refers to an abnormal lateral curvature of the spine, while kyphosis is characterized by an excessive outward curve of the spine, typically in the thoracic region. Postural curvature might encompass various spinal shapes, so it does not specifically denote the characteristic excessive inward curve seen in lordosis.
