What is diathermy?

electromagnetic energy from the radio frequency portion of the EM spectrum
What type of wave is in the middle? (wavelength, and frequency)

shortwave

SWD; PSWD

pulsed is non thermal
What type of wave has the shortest wavelength/frequency?

microwave

MWD; magnetron oscillator
What type of wave has the longest wavelength and lowest frequency?

longwave
How deep does deep heat penetrate?

3-5cm
How deep does superficial heat penetrate?

1-3cm
What type of diathermy heats the tissues thru conversion of electromagnetic energy into heat?

shortwave diathermy
What are the 2 types of SWD?

condenser field

induction field
Which field produces heat and transfers into tissues between 2 electrodes or capacitive plates?

condenser

*heat goes a little bit deeper
What field heats up tissues, is more superficial, but is still considered deep?

induction

uses 1 electrode (drum)
What type of currents does all diathermy create?

eddy currents
What do eddy currents do?

causes tissues to oscillate to create heat/energy
