Kyphosis is the medical term for an excessive forward curve in the thoracic spine. Dowager's hump and neck hump are two informal names for a related but more specific symptom.
The safest way to correct a hunched back is a short daily routine that mobilizes the rib cage and thoracic spine, strengthens the muscles between the shoulder blades, and stretches the chest and hip flexors pulling you forward.
Kyphosis is a musculoskeletal condition in which the upper spine curves forward beyond the normal range, creating a rounded or hunched appearance in the upper back.
