Kyphosis is a forward curvature of the upper spine. Some rounding is normal but kyphosis generally refers to an increased rounding of 40 to 45 degrees or more. This condition is often called hunch back. Kyphosis may be due to degenerative diseases, osteoporosis with compression fractures of the vertebrae, developmental problems or trauma to the spine. This condition can affect all ages, cause few problems in mild cases but also be so severe it can affect your breathing/lungs, nerves, organs, etc. Physical Therapy can help with postural education, strengthening and stretching exercises and ergonomic tips to prevent the condition from worsening.
