What is the normative ROM for thoracolumbar extension in degrees?

Explanation:
The motion available in the thoracolumbar region during extension is limited by the anatomy of the spine and rib cage, so the typical amount of extension from neutral is modest. In healthy adults, the combined thoracic and lumbar extensor range is about 20–25 degrees, with 25 degrees commonly cited as the normative upper limit. That’s why the best choice is the one that reflects approximately 25 degrees of extension. Values much higher than this (like 30–45 degrees) would exceed the usual norm for this region, and a much smaller value (like 15 degrees) would be below what is typically observed in a healthy population.
