While different in the mechanism at which it occurs, both shortwave diathermy and ultrasound use ___________ as the mode of heat transfer?
Vapocoolant spray is a liquid that evaporates on skin contact. It is most commonly used in the treatment of ____________, because of its ability to decrease motor neuron activity.
Which is colder, a cold pack made of silica gel, or a bag of ice? This is because it undergoes a state change, and therefore, requires more energy to do so.
Both continuous and pulsed ultrasound are responsible for producing non-thermal tissue changes such as increased calcium, macrophage activity, cell membrane permeability, and nerve regeneration. This occurs as a result of stable cavitation and ______________.
When administering ultrasound, sound waves cause vibration of gas bubbles within the tissues. If ____________ occurs, these gas bubbles pop, and underlying tissues can be destroyed. Because of this, it is important to ensure the machine of choice has a low beam nonuniformity ratio, and the sound head remains in motion during the duration of treatment.
Your patient is three days s/p TKR, and Is complaining of increased pain, with the presence of edema. It would be MOST beneficial to apply the ____________ after treatment in order to reduce blood flow, metabolic rate, and nerve conduction velocity, and therefore, minimize the patients impairments.
Your patient has chronic low back pain, and therefore, you’ve decided to end your treatment with 15 minutes of heat. Prior to administering the hot pack, you remember it is not advised to lie you patient in the ____________ position, as this will increase the rate of tissue heating, decrease circulation, and potentially cause burns.
