How is Flat Back posture characterized?

Flat Back posture is primarily characterized by a reduced lumbar curve, which contributes to a flatter appearance of the lower back. In individuals with this posture, the normal lordotic curve in the lumbar region is diminished, resulting in a straightened spine that lacks the typical curvature. This condition can lead to misalignments in the vertebral structures and could be associated with tightness in the hamstrings and hip extensors, making the lower back appear flatter than usual. Therefore, the description of a reduced lumbar curve and a flat appearance accurately captures the essence of Flat Back posture. Understanding this characteristic is crucial for identifying and addressing postural imbalances effectively in both practice and rehabilitation settings.
