Chiropractic therapy theory
Chiropractic therapy have china chiropractic version and American version, so today we talk about American chiropractic.
spine motion got 3D six degrees of freedom .It is the frontal axis flexion and left & right translation ；The vertical axis directs contraction and traction, clockwise & anticlockwise rotation; sagittal axis left & right bending and forward & back translation.it is very importance to study the muscle, ligament which related to posture and spine. Because the changes spine in space of 3D Six degrees of freedom will affect the spine.
LDH Patient Spine motion NP unable to contraction when spine doing motion .So the stresses changes, but the spine is the bearing part when doing flexion and rotation. So the main reason to cause LDH is Spine got hurt from the violently bending and rotation .So the spine bearing abilities will getting weak when suffering long time violently spine rotation or older . And it is will reduce the 3D movement function go weak, then bring a lots problems to the patients. Such as ,unstable spine cause extrude NP，muscle ，ligament got hurt ,and the spine curves will scoliosis ，lordosis. In order to balance the body so the whole spine normally got compensatory reaction.
Many Manipulation therapy are able to relieve the pain or get it recovery for LDH patients. But so far no objective evidence shows that manipulation therapy can get the NP Back to right position. So it is just inference for manipulation therapy only. There are a lots clinical practice has confirmed that chiropractic therapy is able to get LDH Patient fully recovery by reduce the anomaly stress of Spine inside and out.
Chiropractic using the creep theory from bio mechanics （determine by the elastic mechanics nature of muscle, ligaments ，spine ）. When LDH patient having the spine bending of compensate reaction, Bio mechanics think this kind of functional bending happened cause by the gravity acting on the slack ligaments and muscle .Creep is means that when putting first force into the spine, the transformation will be big by time, even the force do not change by time.
Chiropractic therapy is mainly base on the’ Bio-mechanical leverage’. Turn the little join back to original position via a rotation force, reduce the anomaly higher pressure in the LDH and to improve nervous system pain or injury from LDH irritating .So the LDH can be fully recovery.
