Flashcards in Modalities Deck (22):
1

heat is transferred from a warmer object to a cooler one (ratio depends on exposure time and temperature)

conduction

2

transference of heat through the movement of fluids or gasses

convection

3

heat energy transfer from one object through space to another object

radition

4

generation of heat from another energy form such as sound, electricity, and chemical agents

conversion

5

muscle temps can be reduced as deep as?

38.3- 4 cm

6

slight increase in temperature during cooling

hunting response

7

contain silicate gel in a cotton pad; 160-170 degrees

Moist Heat Packs

8

extremity tank, lowboy tank (full body), highboy (hip/leg) provides convection and conduction; 100-110

whirlpool baths

9

effective in treating chronic injuries to irregular areas of the body; 126-130

paraffin

10

facilitate increase temperature to increase blood flow to area without causing accumulation of additional edema; 100-110 to 50-60; 3:1: cold for 19-20 minutes

contrast bath

11

ultrasound heating: mild, moderate, vigorus

mild 1
moderate 2-3
vigorous 3-4

12

flow of fluid tissue compenents results in mechanical pressure wabes -alters cell membrance permeability to Na+ and Ca2+ ions

microstreaming

13

formation of gas filled bubbles that expand and compress due to pressure changes in fluid

cavitation

14

direct, galvanic current; usually low voltage

monophasic (DC) current

15

direction of current flow reverses itself one during each cycle

biphasic

16

usually contains three or more pulses grouped together; interrupted for short periods of time and repeat themselves at regular intervals

polyphasic (pulsatile) current

17

light and deep effleurage=

stroking

18

used to loosen heavy tissue trapes, lats or tricepa

petrissage (kneading)

19

often used around a joint where tissue is thin or unyeilding scars

friction

20

cupping, hacking, or pincing

tapotement (percussion)

21

rapid movement that produces a quivering or trebling effect

vibration

22

heat deep tissues by introducing a high frequenct electrical current

shortwave diathermy
