Thoracic Kyphosis

Definition

The natural posterior convexity of the thoracic spine. Normal thoracic kyphosis is approximately 20-45 degrees (Cobb angle). Excessive kyphosis (hyperkyphosis) is a rounded upper back posture where the curve exceeds 45 degrees. Reduced kyphosis (flat thoracic spine) limits rib cage mobility and breathing mechanics.

Clinical Significance

Excessive thoracic kyphosis is one of the most impactful structural findings in biomechanical assessment. It drives scapular protraction (contributing to shoulder impingement), limits overhead reach, forces cervical hyperextension (contributing to neck pain), and restricts rib cage expansion (reducing breathing capacity). Correcting thoracic position often resolves shoulder and neck symptoms downstream.

How AKMI Assesses This

AKMI measures thoracic kyphosis through lateral postural photography, wall angel assessment, and thoracic extension ROM testing. The assessment correlates thoracic position with scapular position, shoulder ROM, and cervical alignment.
