Dual Probe
Indicates which probe has the greater heat, a relative thermometer
Components of dual probe:
- Themocouples (2)
- Galvanometer (1)
- Increments (50)
What is the role of instrumentation in practice?
- Assists in determining the need for adjustments
- Measure patients response to adjustment
Dynamism Theory
A living organism is dynamic in response as it adapts to in its internal and external environments
What are some sources of heat production?
- Muscle metabolism
- Vasodilation and vasoconstriction
- Glandular activity
- General body metabolism mediated by the nervous system
What is the purpose of chiropractic instrumentation?
To objectively assess the nervous system by measuring heat changes, aiding in identifying subluxations and evaluating patient responses to care.
What does the “Pattern” in pattern analysis indicate?
A static, repeatable heat distribution on the spine, suggesting a subluxation and reduced adaptability.
What are the required tools for pattern analysis?
Dual probe instrument (thermocouple or infrared) and a graph recorder.
When should a chiropractor adjust based on pattern analysis?
Only when the pattern reappears, indicating a return to the subluxated state.
What is the purpose of break analysis?
To detect rapid needle deflections (“breaks”) at specific spinal levels to locate subluxations.
How is a “break” defined in break analysis?
A quick, sharp deflection of the needle occurring over a single spinal segment or dermatome.
What instrument is used in both pattern and break analysis?
A dual probe thermocouple device.
What is the galvanometer’s role in a dual probe instrument?
It amplifies the thermocouple’s signal and visually displays relative temperature differences.
What is the theory behind using heat to detect subluxations?
Subluxations alter sympathetic activity, leading to heat asymmetry due to vasomotor changes.
What does the Dynamism Theory state?
Health is the body’s ability to dynamically adapt to internal and external stresses.
What are the three main types of heat transfer in the body?
Conduction, convection, and radiation.
What is HRV and why is it relevant in chiropractic care?
Heart Rate Variability; it measures autonomic nervous system balance and adaptability—more variability indicates better health.
What historical device did early chiropractors use to identify subluxations?
“Hot boxes,” which referred to warm spinal areas believed to indicate dysfunction.
What is the Tytron instrument?
A non-contact infrared scanner used for pattern and break analysis.
What does a heat swing indicate in break analysis?
A gradual deflection over multiple segments—not a subluxation indicator.
What are signs of a patient being “in pattern”?
Persistent heat asymmetry, reduced adaptability, and ongoing subluxation signs.
What are the four sources of heat production in the body?
Muscle metabolism, vasomotor activity, glandular activity, and nervous system-mediated metabolism.
What must be done before taking an instrument reading?
Patient should acclimate to room temperature (usually for 10 minutes).
What are the three procedures to establish a heat pattern?
Take three separate readings spaced over 24 hours and look for consistency.
