HVLA Flashcards
what is the mechanism for incerased ROM
joint traction separates teh surfaces of the joint which creates an incerase in joint volume
when partial pressure of CO2 is reached, the co2 that is dissolved whithin the synovial fluid forms a bubble which then collapses, this process is known as tribonucleation.
beacause of teh pressure and volume changes the joint has greater range of motion where there is greater mm of separation for the amount of force applied
what is the decreased pain theraputic mechanism
hvla has an immediate effect in pressure pain sensitivity and reduction in pain
hvla can activate inhibitory interneurons that can inhibit the transmission of pain signals by creating a pain gate at the synapse between the first and second order neurons, blocking the pain signals from the site of injury from synapsing with the spinal cord and making it to the brain
it can also inhibit descending systems at the highest centres of the CNS, particularly the periaqueductal grey matter of the midbrain, by sending messages down the spinal cord to inhibit pain
how do general ST mechanisms help to incerase fluid drainage
fluid systems are passive and rely on differentials of pressure to move fluid
omt stretches and moves joints that then screates pressure changes in and around teh joints, assisting in moving excess fluid
how does general st ttt reduce pain
through mehcanotransduction which is the ability of the cell to sense, integrate, and convert mechanical stimuli into biomechnaical signals which have a part in deactivating pain signalling pathways
WHAT ARE THE THERAPUTIC MECHANISMS FOR MET
STRETCH OF MYOFASCIAL TISSUES
INHIBITOIN OF PAIN
FLUID DRAINAGE
IMPROVEMENT OF PROPRICEPTION AND MOTOR CONTROL
REFLEX MUSCLE RELAXATION
HOW DOES MET STRETCH MYOFASCIAL TISSUES
PLACING THE JOINT OR MUSCLE INTO A POSITION OF STRETCH, STRETCHES CONNECTIVE TISSUES AND CONTRACTILE FIBRES
HOW DOES MET ASSIST FLUID DRAINAGE
CONTRACTION AND RELAXATION CREATE PRESSURE DIFFERENTIALS WITHIN A JOINT WHICH CAN STRINGLY INFLUENCE PASSIVE SYSTEMS SUCH AN VENOUS AND LYMPHATIC DRAINAGE
