The human body is unique in the way it walks on two legs and balances the weight of the body and head over the hips in the most convenient and economical way.
This balance though is delicate, and a Paralysis Hangover disrupts the balance and creates a situation, that for most of the affected persons leads to painful and even disabilitating conditions.
What brings imbalance into the ingenious compound of the human body are first and foremost the psoas muscles1. See picture 15 left. Psoas is a set of muscles connecting the lumbar vertebrae to the big thigh bone, femur. Their contraction boughs the lumbar part of the vertebrae column forward, like when you are standing bend to pick up something from the floor.
The uttermost contraction of the psoas is seen in the position, we have become familiar with, the fetal position. As you can see, in this position the psoas is as short as it can possibly get. See picture below right.
If, after a Paralysis, the psoas is not released, it will continue to pull the lumbar vertebrae2, as if the body was still fainted. This downward pull will force the lumbar out of its natural curvature.
Most people will not know, that their nervous system is still in a Paralysis Hangover with the dorsal vagus in a shut down state. Thus they will get up on their feet, stretch the back as good as they can and get on to do their duties, trying to carry their suffering bravely.
This will obviously conflict with the tensions in psoas, which continues to execute a permanent stress on the lumbar vertebrae.
As the human body is lifted out of the fetal position and erected, it comes to a point, where the forces of the psoas draws the lumbar vertebrae backwards instead of forward. This condition is called lumbar hyperlordosis.
Often times the consequences are lower back pain and it eventually leads to a spinal disc herniation. See picture below.
