Flashcards in Therapeutic Modalities Deck (21):
1

Negatively charged electrode in a direct current system

Cathode

2

Transfer of energy between two objects via a medium as it moves across the body, creating temperature variations

Convection

3

Involves the changing of another energy form into heat

Conversion

4

As angle deviates from 90°, the energy varies w/ the cosine of the angle
Effective energy = energy x cosine of the angle of incidence

Cosine law

5

The use of cold treatments before an exercise session

Cryokinetics

6

Local elevation of temperature in tissues produced by the therapeutic application of high-frequency electrical current, US, or microwave radiation

Diathermy

7

Inverse relationship that exists between the amount of penetration and absorption; the more energy absorbed by superficial tissues, the less energy available to be transmitted to underlying tissues

Grotthus-Draper Law

8

The intensity of radiant energy striking the tissues (E) is DIRECTLY proportional to the square of the distance (D) between the source of the energy (ES) and the tissues
E = ES / D2

Inverse square law

9

Technique whereby direct current is used to drive charged molecules from certain medications into damaged tissue

Iontophoresis

10

The greater the resistance or impedance, the more heat that will be developed; tissues w/ a high fluid content absorb more of the energy and are heated to a greater extent

Joule's Law

11

Therapeutic agent that promotes optimal healing while reducing pain and disability

Modality

12

Current (I) in a conductor increases as the driving force (V) becomes larger or as resistance (R) is decreased
I = V / R

Ohm Law

13

Introduction of anti-inflammatory drugs through the skin w/ use of US

Phonophoresis

14

Deflection of an energy wave b/c of a change in the speed of absorption as the wave passes between mediums of different densities

Refraction

15

US; conversion of an electrical current into mechanical energy as it passes through a piezoelectric crystal housed in the transducer head

Reverse piezoelectric effect

16

Heat application

Thermotherapy

17

Unit of electrical power; for electrical current
Watts = voltage x amperage

Watt

18

Law that states that bone and soft tissue will respond to the physical demands placed on them, causing the formation of collagen to remodel or realign along the lines of stress, thus promoting healthy joint biomechanics

Wolff Law

19

Region of injured tissue before vasodilation

Zone of primary injury

20

Region of damaged tissue following vasodilation

Zone of secondary injury

21

Increased blood flow into region or body part once tx has ended

Hyperemia
