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
