What theory is the following statement?
Tract in Spinal Cord – one signal at a time to the brain Hot or cold over-ride the pain signal thus reducing the perception of pain Temperature signals are faster than pain signals to the spinal cord
Pain Gate Theory
When cold application is used, acute pain decreases, what happen if hot application is used?
perception of pain increases
In chronic pain when cold application is used, pain decreases, what happen if hot application is used?
perception of pain decreases
Which statement about Hunting’s response is True?
a) The body is exposed to extreme cold
b) The body’s immediate response is vasodilation
c) The body’s secondary response is vasoconstriction
The body’s immediate response is vasoconstriction, secondary response is vasodilation
_________ - occurs because of a histamine response - the histamine response happens because the cold has irritated the tissue. This mechanism will bring MORE blood to the area in an attempt to warm the area and return it to stasis, the histamines are then “washed away” by the increased blood flow.
Hunting’s response: True or False.
If the application of cold is prolonged, meaning the initial vasodilation was not sufficient enough to restore a “normal” temperature (homeostasis), the body will repeat the vasoconstriction/ vasodilation loop every 15-20 minutes, in an attempt to return the tissue to homeostasis.
States the velocity of chemical reaction increases by at least two times for every increase of 10 degrees C. And is particularly important in very prolonged hot applications because as tissue temperatures increase, metabolic activity increases beyond the control of the body.
Van’t Hoff’s Law
What are the stages of Injury?
Duration of acute injury where in there is much pain, inflammation is visible and presence of Redness/hot to touch due to influx of blood- white blood cells.
1 to 3 days
Range of motion when acute injury is present.
True or False
Cold type of hydrotherapy is used in acute injury.
Duration of subacute injury where in there is less redness in the skin - warm/cool to touch, inflammation is not visible, less pain is felt, and can do some range of motion.
Early 4 to 7 days
Late 7 to 14 days
True or False
Heat type of hydrotherapy is used in subacute injury.
Contrast type is used
Duration of subacute injury where scar tissue in the skin is present, inflammation is None or chronic edema (adhesions,histamines, nerve lesions), pain is limited to none, and Heat is used for hydrotherapy.
14 to 21 days or more
