1

How did Hippocrates utilize mud packs to measure thermography?

Watched where it dried first

2

Where did the Chiropractic desire to utilize thermography come from?

The desire to find, quantify and verify the correct of VSC

3

What year was the neurocalometer developed?

1924

4

Who developed the first neurocalometer?

Dossa Evins

5

What does the neurocalometer use to measure temperature?

Thermocouples

6

What are the 2 major types of thermography?

1.) Liquid crystals

2.) Infrared

7

How do liquid crystals measure thermography?

LCT is based on the ability of thermallly sensitive cholesteric crystals to change color in response to the body's emission of infrared (heat) waves

8

What are 5 ways to measure infrared thermography?

1.) DTG

2.) Visitherm

3.) Insight 7000

4.) Tytron

5.) Telethermography

9

What are 6 advantages to thermography?

1.) Non-invasive

2.) Non-ioning radiation

3.) Painless

4.) Safe

5.) Somewhat portable

6.) Effective

10

What are 5 disadvantages of thermography?

1.) Expensive

2.) Strict protocol

3.) Interpretation requires a high level of training & expertise

4.) Relatively time consuming

5.) Usually needs a special room

11

What are the 3 physiological postulates of thermography?

1.) Body is divided into dermatomes (& thermatomes)

2.) Side to side is generally symmetrical unless dysfunction exists

3.) Any anomalous deviation from a gradually increasing paraspinal skin temperature from S2-C1 may suggest VSC or remote dysfunction

12

Theromgraphy is a picture of _____, while X-ray is a picture of _____.

Physiology

Anatomy

13

What produces reflex vasoconstriction, through the ANS, of the arterioles of the skin

Sensory nerve irritation

14

What are 4 indications of thermography?

1.) Outcome assessment toold for initial assessment & to monitor progress/response

2.) Equivocal clinical findings

3.) Need for medico-legal evidence

4.) Unsatisfactory response to care

15

What determines if a referral is needed?

A change in technique of patient has reach MMI

16

What are the 9 applications of thermography?

1.) Determine & evaluate the existence & extent of VSC (when & when not to adjust)

2.) Differential diagnosis

3.) Diagnose sensory/autonomic nerve dysfunction

4.) Diagnose sensory nerve irritation

5.) Evaluation for changes of procedure

6.) Monitoring &/or evaluating the treatment effectiveness/measure progress

7.) Evaluation of traumatic injuries

8.) Objective evidence for permanency evaluation

9.) Differential diagnosis for referral, especially vascular problems in extremities vascular insufficiency

17

What are the 4 key areas for the proper exam when testing thermography?

1.) Exam room temperature & environment

2.) Patient preparation

3.) Proper detector or machine set-up

4.) Recording of images
