Answer :
Final answer:
Lordosis, also known as swayback, is an excessive anterior curvature of the lumbar region of the vertebral column. It is most commonly associated with obesity or late pregnancy, causing an anterior tilt of the pelvis and exaggerated lumbar curve. A range of 40-45 degrees of lordosis, measured from the DMMC, indicates an excessive curvature.
Explanation:
Lordosis, also known as swayback, is an excessive anterior curvature of the lumbar region of the vertebral column. It is most commonly associated with obesity or late pregnancy. The accumulation of body weight in the abdominal region causes an anterior tilt of the pelvis and a pronounced enhancement of the lumbar curve. Typically, a normal lordotic curve ranges from 20-25 degrees as measured from the DMMC (dynamic motion control center). However, a range of 40-45 degrees may indicate an excessive lordotic curve.
