Posture breakdown causes lumbar disc breakdown
434 people average age of 43 were classified by their lumbar curves into one of three groups
normal lordosis, reduced lordosis and increased lordosis.
MRIs measured DJD. In addition, the mobility of each segment as well as its angular and translation motion was measured with positional MRI.
Observation: Increased lordosis reduced less lower and upper lumbar motion. Mid lumbar motion was increased, apparently taking up the slack.
- Changes in sagittal alignment may lead to kinematic changes in the lumbar spine. T
- Curve changes influence load bearing and disc degeneration
- Sagittal alignment, disc degeneration, and segmental mobility likely have a reciprocal influence on one another.
