13
Q
What does ligament deformation allow for?
A
It allows spinal vertebrae to temporarily move apart
14
Q
How does traction affect ligaments?
A
-Ligaments can be contracted or shortened by injury or chronic postural problems
-Traction encourages adaptive changes in length and strength
-Places pressure on structures within the ligamentous complex (proprioceptive nerves)
-Activation of proprioceptive fibers provide a gating mechanism similar to TENS
15
Q
What is the function of normal intervertebral discs?
A
-Act to dissipate compressive forces within the spine
-Internal pressure increase, but nucleus pulposus does not move out with change in weight bearing forces
-80% of compressive load in spine is taken up by the disc
16
Q
What happens to the intervertebral discs when they are herniated?
A
-Lose fullness, which moves vertebrae closer together
-Annular fibers bulge
-Nucleus shifts according to fluid-dynamic principles (path of least resistance if annulus is damaged)
17
Q
How does traction help treat intervertebral disc abnormality?
A
-Decreases central pressure
-Return of nucleus to central position
-Tension on annulus fibrosus and ligaments surrounding disc (helps to push disc material more centrally)
-Movement of structures relieves pain if pressure is on vascular or nervous tissues
-Allows for improved fluid exchange within disc and spinal canal
-Possible reduction of disc herniation
18
Q
How does traction affect the facet joints?
A
-Traction separates joint surfaces up to 1-2mm
-Decompresses articular cartilage, increasing synovial fluid exchange to the cartilage
-Stimulates proprioceptive nerves at the facet joint capsules
19
Q
What type of traction is best if you are trying to promote fluid movement?
A
Intermittent traction, because traction, then release will move the fluid around
20
Q
