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)
pulsed is non thermal
What type of wave has the shortest wavelength/frequency?
MWD; magnetron oscillator
What type of wave has the longest wavelength and lowest frequency?
How deep does deep heat penetrate?
How deep does superficial heat penetrate?
What type of diathermy heats the tissues thru conversion of electromagnetic energy into heat?
What are the 2 types of SWD?
Which field produces heat and transfers into tissues between 2 electrodes or capacitive plates?
*heat goes a little bit deeper
What field heats up tissues, is more superficial, but is still considered deep?
uses 1 electrode (drum)
What type of currents does all diathermy create?
What do eddy currents do?
causes tissues to oscillate to create heat/energy
