Harness medical treatment

In sciatic neuralgia treatment, there is a thing called the harness medical treatment.
I call a cure using the corset the harness medical treatment, and the symptoms such as pains are used for a particularly terrible period.
To a corset, there are an elasticity corset and a resilient corset, but it is the elasticity mainly that is used for sciatic neuralgia treatment.
The resilient corset is used at time to fix lumbar vertebrae after an operation.
For a cure, I protect lumbar vertebrae with the obstacle by binding a waist with an elasticity corset and can prevent that a pain comes out.
When muscular strength of an abdominal muscle / the back of the waistline falls, I serve to support lumbar vertebrae instead.
In addition, the vertebral canal which the nervous system in the waist goes along gets narrow, and I fix it with a corset, and, in the case of the spinal canal stenosis to suppress nerve, the backbone does not lengthen.
But the muscle of a fixed part becomes gradually weak when I fix a waist in harness for a long time.
I hear the explanation of the doctor properly to prevent the fall of the muscular strength, and it is important to keep a right wearing method, a period of service well.
