1

dia-thermy means

through heat

2

diathermy is a high blank modality emitting blank energy

frequency, electromagnetic

3

two types of diathermy

shortwave, microwave

4

two types of shortwave diathermy

continuous, pulsed

5

blank diathermy is no longer used

longwave

6

shortwave diathermy forms blank fields in tissue

magnetic

7

microwave diathermy forms blank fields in tissue

electric

8

blank diathermy is rarely used because it heats very quickly and can burn skin/cause hot spots

microwave

9

shortwave diathermy is basically a radio blank and the patient is like the radio blank

transmitter, receiver

10

the blank regulates shortwave diathermy

FCC

11

shortwave diathermy converts blank current into radio frequency

AC

12

magnetic field produces an increase in blank motion among molecules in shortwave diathermy as well as blank currents

kinetic, eddy

13

current flow of shortwave diathermy is greatest in tissues with the blank resistance such as blank

least, fat

14

current absorption is greatest in tissues with low blank like muscle and blood

impedance

15

shortwave diathermy used today that is used to create thermal and non thermal effects

pulsed SWD

16

blank pulse creates more energy to tissue

wider

17

faster pulse blank in SWD correlates to a greater amount of energy produced into tissue

rate

18

pulse rate is measure in blank

hertz

19

PSWD power/intensity is measure in blank

watts

20

the pulse is blank more than blank

on, off

21

two physiological effects of diathermy

thermal, non thermal

22

charged particles oscillate producing kinetic energy theory for thermal effects

ionic oscillation

23

dipolar or water molecules rotating and producing kinetic energy theory of thermal effect

dipole rotation

24

mild heat causes blank of sensory nerve endings

sedation

25

three non thermal effects of diathermy

repolarizing damaged cells, regularized cell growth, reestablish NA K pump

26

non thermal effect of diathermy improves blank funciton and blank cells in a wound

cell, white

27

diathermy can be used to control blank and blank, and tissue blank

pain, edema, healing

28

diathermy should not be done over blank plates in adolescents

epiphyseal

29

diathermy can reach blank tissues and reflects off bone so it wont cause bone blank

deeper, burn

30

only heat diathermy that can pass heat bone

capacitive plates
