Spirometry measures breathing or the volume of inspiration/expiration in ML. Results of a spirometry measurement are referred to as vital capacity (VC). Vital capacity is an indicator of lung function and lower than expected values of VC may occur when a thoracic scoliosis is present. Patients measuring Cobb >100º, VC may be reduced to <… Read More
A Scoliometer™ is an instrument that measures trunk asymmetry in scoliosis, or angle of trunk rotation (ATR). It is a small, non-invasive device (essentially a mini-level) that is placed over the spine while a person is in a forward bending position. The Scoliometer™ reading indicates the degree of trunk asymmetry (rotation). Research shows that most… Read More
Cobb angle is the “universal standard” of measurement used to quantify a scoliosis for the purpose of measuring curve progression over time. Evaluating scoliosis via Cobb angle is important since it is often the first objective indicator. A curve is considered to be scoliosis at a Cobb angle of 10º or more. Any increase greater… Read More

Updated March 15, 2019: A pleasant young adolescent, accompanied by her parents, came to Boston to see me for Schroth treatment. As we began the evaluation, her father, an MD, looked at me and said, “I read the book, and I’m not sure if her curve classification is a three curve or a four curve.”… Read More
