e-stim
A an easily portable electrical stimulation device used for pain control.
What is Transcutaneous electrical nerve stimulation (TENS)?
Ultrasound frequency for penetration into deep tissue.
What is 1mHz ultrasound?
The means by which a hot pack can relieve pain.
What is sensory analgesia or Gate theory of pain relief?
the two of the means by which ice can decrease the perception of pain.
What are decreasing nerve conduction velocity, elevation of pain threshold, sensory analgesia or gate theory?
Pulsed short-wave, continuous short-wave, and microwave.
What are types of diathermy?
The use of one large electrode referred to as the dispersive electrode and one small electrode for the application of electrical current.
What is a mono-polar technique?
3.3 mHz
What is the frequency of ultrasound for superficial structures?
A semi-permanent blotchy mottling of the skin caused by long term overuse and overheating with a thermal modality.
What is erythema ab igne?
the technique used for muscle stretching to relieve pain from active trigger points.
What is "Spray-and-Stretch"?
Metal implants
What is one of the absolute contraindications for use of diathermy?
The necessary type of current to elicit a tetanic contraction from denervated muscle.
What is direct current or galvanic current?
ERA
What is effective radiating area?
A modality that can increase circulation by heating an area by conduction.
What is a hot pack?
The methods of heat exchange by which cyrotherapy can be achieved.
What are conduction, convection and evaporation?
Diathermy and electrical stimulation.
What two modalities are contraindicated for a patient with a pacemaker?
Pulsed or pulsative current, or alternating current.
What is the type of electrical current needed to elicit a tetanic contraction from an innervated muscle?
The method by which ultrasound can generate heat in the tissues.
What is conversion?
The correct temperature for the water water in the hot pack tank.
What is 158 to 167 degrees Fahrenheit?
The result of the application of cold for an extended period of time results in vasodilation for a period of time then a return to constriction and then a cycling between those two states.
What is a Hunting Response?
Where diathermy devices fit on the spectrum of electromagnetic waves.
What is below the frequency of visible light?
V=IR, where V=voltage, I=current(intensity), and R=resistance
