Q

What is the purpose of chiropractic instrumentation?

A

To objectively assess the nervous system by measuring heat changes, aiding in identifying subluxations and evaluating patient responses to care.

Q

What does the “Pattern” in pattern analysis indicate?

A

A static, repeatable heat distribution on the spine, suggesting a subluxation and reduced adaptability.

Q

When should a chiropractor adjust based on pattern analysis?

A

Only when the pattern reappears, indicating a return to the subluxated state.

Q

What is the purpose of break analysis?

Q

What is the galvanometer’s role in a dual probe instrument?

A

It amplifies the thermocouple’s signal and visually displays relative temperature differences.

Q

What is the theory behind using heat to detect subluxations?

A

Subluxations alter sympathetic activity, leading to heat asymmetry due to vasomotor changes.

Q

What does the Dynamism Theory state?

16
Q

What are the three main types of heat transfer in the body?

A

Conduction, convection, and radiation.

17
Q

What is HRV and why is it relevant in chiropractic care?

A

Heart Rate Variability; it measures autonomic nervous system balance and adaptability—more variability indicates better health.

18
Q

What historical device did early chiropractors use to identify subluxations?

A

“Hot boxes,” which referred to warm spinal areas believed to indicate dysfunction.

19
Q

What is the Tytron instrument?

A

A non-contact infrared scanner used for pattern and break analysis.

20
Q

What does a heat swing indicate in break analysis?

A

A gradual deflection over multiple segments—not a subluxation indicator.

21
Q

What are signs of a patient being “in pattern”?

A

Persistent heat asymmetry, reduced adaptability, and ongoing subluxation signs.

22
Q

What are the four sources of heat production in the body?

A

Muscle metabolism, vasomotor activity, glandular activity, and nervous system-mediated metabolism.

23
Q

What must be done before taking an instrument reading?

A

Patient should acclimate to room temperature (usually for 10 minutes).

24
Q

What are the three procedures to establish a heat pattern?

A

Take three separate readings spaced over 24 hours and look for consistency.
