Q

“knob-ology”?

A

just turning knobs and buttons while not interested in knowing why they are doing it. Modalities is not all evidence based practice.
Application usually precedes theory

Q

When selecting criteria for rehabilitation keep in mind…

A
  1. Correct diagnosis
  2. Definite concept of pathological &physiological changes associated with injury (create problem list)
  3. Outline treatment plan (STG, LTG)

Q

Myths about rehab: True or false, treat injuries, then rehabilitate them?

A

False belief. Rehabilitation is the whole process of returning an individual to pre-injury levels…we treatment with modalities is part of the rehab process. (not something that precedes it)

Q

Myths about rehab: True or false, rehabilitation = reconditioning?

A

False, rehabilitation includes promotion of healing and pain relief (in addition to conditioning activities)
Example: cannot condition someone with a torn tendon until it is healed. Can condition because pain inhibits strength, flexibility, etc.

Q

Myths about rehab: True or false, rehab is primarily physical?

A

False, most clinicians & patients will tell you that rehabilitation is 75% mental and 25% physical. Direct connection exists between mind and body. (some pt seem to “give up” after injury, others must be held back)

18
Q

Cryotherapy

A

Description: Use of cold (~ 32-70F, 0-21C)

Ice massage, ice packs, immersion, cold whirlpool, vapocoolant sprays

19
Q

Thermotherapy

A

Description: Use of superficial and deep heat (~98-109F, 37-43C)
Moist heat packs, warm whirlpool, paraffin wax baths, ultrasound, diathermy, ultraviolet

20
Q

Hydrotherapy

A

Description: Application of water

Whirlpool, immersion

21
Q

Electrotherapy

A

Description: Use of electricity

TENS, NMES, iontophoresis, Diathermy

22
Q

Light Therapy

A

Description: Use of electromagnetic radiation.

Laser, light theryapy, infrared

23
Q

Mechanotherapy

A

Description: Use of motion, force, pressure.

Massage, mobilization, intermit, compression, CPM, traction, whirlpool, ultrasound

24
Q

Exercise

A

Description: Performed by patients

Various (cryokinetics)

25
Q

Electomagnetic Spectrum: What is the difference between Infrared Radiation and Ultraviolet Radiation?

A

Infrared region: produces heat, located beyond visible red region.
Ultraviolet region: produces chemical changes, located beyond the visible violet region

26
Q

Common Theoretical Characterististcs of EM Radiation

A
  1. They all travel at an equal velocity
  2. The basic unit of radiant energy is a PHOTON
  3. They travel in a straight line until they come in contact with some other surface.
    * Reflected, Refracted, Absorbed, or Transmitted
27
Q

Describe the characteristics of Wavelengths & Frequency

A

Inverse relationship
Frequency - # of cycles per sec (Hz or MHz)
Wavelength - distance between one wave and the next
Velocity = (wavelength)(frequency)
3x108m/sec (speed of light)

28
Q

Depths of electromagnetic modalities?

A 
E-stim = Anywhere btw electrodes
MW diathermy = 5cm
SW diathermy = 3cm
Laser = 10-15mm
everything else 1cm
ultrasound = 1mm
29
Q

What are Photons

A

“packets” of energy
The amount of energy in a photon is a function of the frequency of the EM wave.
Greater Frequency = shorter wavelength (has more energy
lower frequencies have no therapeutic values

30
Q

The four different ways EM radiation is transfered/moved

A

Reflection
Refraction
Transmission
Absorption

31
Q

Reflection

A

As waves hit substance, they bounce back. No penetration into substance.

32
Q

Refraction

A

Waves bend as they pass through substance

33
Q

Transmission

A

Wave is transmitted through substance. Depth of penetration is dependent on energy waves.

34
Q

Absorption

A

Waves are absorbed by tissues and turned to heat

35
Q

TRUE or FALSE

Radiations that have the shortest wavelengths have greatest depth of penetration.

A

False
longest
example: US

36
Q

Name the Laws covering the effects of EM radiation

A

Arndt-Schultz Principle
Law of Grothhus-Draper
Cosine Law
Inverse Square Law

37
Q

Arndt-Schultz Principle

A

No reaction or change can occur in the tissues if the amount of energy absorbed is insufficient to stimulate the absorbing tissue.
Goal: deliver sufficient energy to stimulate tissues to perform normal function. (not to much though)

38
Q

Law of Grothhus-Draper

A

The greater the amount of energy absorbed, the less penetration through the tissue.

If therapeutic energy is not absorbed by superficial tissues, it will penetrate deeper

39
Q

Cosine Law

A

Radiant energy is more easily transmitted to deeper tissues if source of radiation is at a right angle to area being radiated.
Important for ultrasound
Sun-bathing example, less EM energy will be reflected.

40
Q

Inverse Square Law

A

The intensity of the radiation striking a surface varies inversely with the square of the distance from the source. Closer you are to the skin the more energy is passed.
Important for Diarthermies and ultraviolet light

41
Q

Acoustic waves vs EM waves

A

Transmit waves transmit BEST through solids and not at all in vacuums. Inverse for EM.
Transmitted by collisions. EM waves slowed by collisions.
Accoustic waves do not travel as fast as EMS waves
