Scoliosis is an abnormal curvature of the spine. There are several types of scoliosis: idiopathic, congenital, neuromuscular, and degenerative. Scoliosis most commonly affects the thoracic and thoraco-lumbar spine. Radiographs of the mid-back will show a visible lateral curve resembling an “S”. Structural (abnormalities in the bone) scoliosis’ should be evaluated and monitored by an orthopedic physician, for possible bracing to slow down the progression of the curve. Non-structural scoliosis usually due to joint dysfunction and or muscle imbalance can be treated with manual therapy with positive results.
