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

    SWD; PSWD

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

    MWD; magnetron oscillator
  4. What type of wave has the longest wavelength and lowest frequency?
    longwave
  5. How deep does deep heat penetrate?
    3-5cm
  6. How deep does superficial heat penetrate?
    1-3cm
  7. What type of diathermy heats the tissues thru conversion of electromagnetic energy into heat?
    shortwave diathermy
  8. What are the 2 types of SWD?
    condenser field

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

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

    uses 1 electrode (drum)
  11. What type of currents does all diathermy create?
    eddy currents
  12. What do eddy currents do?
    causes tissues to oscillate to create heat/energy
