In Sway Back posture, which curve is typically increased?

Anteroposterior curve

Posterior thoracic curve

In Sway Back posture, the posterior thoracic curve is typically increased due to the backward positioning of the thoracic spine. This posture is characterized by a forward shift of the pelvis and an excessive extension in the lumbar region, resulting in a flattened or reduced lumbar curve and an exaggerated thoracic curve.

This alteration in curvature leads to a more pronounced rounding of the upper back, which is a defining aspect of Sway Back posture. The thoracic spine's natural kyphosis is enhanced, leading to a greater posterior curve in that area. Understanding the mechanics of this posture is essential for identifying alignment issues and designing corrective exercise programs for clients.
