lordosis

An abnormal degree of forward curvature of the lower part of the spine, often associated with abnormal backward curvature of the upper part (KYPHOSIS). Lordosis is an exaggeration of the normal forward curve and often causes the buttocks to appear unduly prominent.

lordosis

exaggerated forward curve of the lumbar spine. There is a normal wide variation in spinal curvature and lordosis is common during the accelerated phases of growth. In sport it is usually the result of poor posture or unequal development of the supporting spinal musculature. Treatment is therefore targeted at correcting posture and improving muscle control, balance and strength.

lordosis

abnormal spinal extension characterized by increased sagittal-plane curvature of lumbar spine, associated anterior tilt of upper pelvis, relative superior orientation of acetabulum (and hip joint) and genu recurvatum

lordosis (lōr·dōˑ·sis),

n exagger-ated anterior spinal curvature at the lumbar concavity. Also called
swayback.
