What is Mottling of the skin
100
A protective response that results in a sustained isotonic contraction
What is muscle guarding
100
Shortening of connective tissue may result from
What is injury or immobilization
100
This is the temperature of the water in the hydrocollator, and thus necessitates close monitoring of the patient to prevent burns
What is 170 degrees F
200
Fluidotherapy transfers heat by this method
What is convection (air moving past)
200
Muscles of the back are not generally heated through unless the heating agent is left on for this length of time
What is 30 minutes
200
The increased skin temperature produces a decrease in alpha motor neuron activity, thus relaxing tense muscles, which is why a _________such as a HMP can work to reduce muscle guarding
What is a Superficial Heating Agent
200
As a result of heating, the fluid in a joint capsule becomes less thick, and the joint more mobile. It is scientifically described as being__
What is less viscous
200
The number 8
What is the usual number of layers of towels between the HMP and the patient

An example of Conversion - when energy is transformed from one form to another
What is Ultrasound
300
An increase in tissue metabolic rate has been correlated with ___
What is an increase in tissue temperature
300
The application of Heat has a direct effect by interrupting the _______ - _________ cycle, thereby decreasing muscle guarding
What is the Pain- Muscle Spasm
300
Heat can increase the elastic properties of which three tissues
What is muscle, tendon and joint capsule

Your patient is not able to lay prone, but needs a lumbar HMP. Describe the possible treatment position
What is sidelying with a bolster behind to keep the HMP in place
400
Temperature difference time of exposure thermal conductivity of the tissue intensity of the agent
What are factors affecting the extent of temperature change?
400
Heat may have a beneficial role in this category by improving perfusion, increase oxygen delivery, and enhancing removal of bacteria from the site
What is wound healing
400
Muscle spasm can also be decreased by the use of a deep heating agent such as
What is Continuous Ultra Sound
400

Things which induce muscle guarding
What are trauma, fear of pain, injury, and painful stimulus
500
After tissues have been warmed for 15-30 minutes, your instructions to your patient regarding vigorous exercise are
What is 'Not for 30 minutes but improved function for 2 hours following'
500
Your elderly patient has neck/shoulder pain, and reports that HMP is too heavy on her shoulder when she is sitting in the wc. What is your best response
What is to transfer her to a surface where she can lay down, and place the HMP on her shoulders in supine
