Q

Soon after DD Palmer hypothesized that subluxation was caused by trauma, toxins, and/or autosuggestion, he added in ___ theory

A

vibratory

30
Q

What does DD Palmer’s vibratory theory state?

A

Nerves vibrate normally at 200 per minute; this represented the tone of the nervous system

31
Q

What is innate intelligence?

A

DD Palmer says it’s “individualized intelligence which runs all the functions of our bodies”

32
Q

Who is considered the developer of chiropractic?

A

BJ Palmer

33
Q

In 1934, BJ Palmer established four criteria for subluxation:

A
  • Misalignment of vertebra in relation to adjacent segments
  • Occlusion of a foramen (including the canal)
  • Pressure on spinal nerve roots
  • Interference to transmission of mental impulses
34
Q

Later in BJ Palmer’s career, what region of the spine did he focus on?

A

Upper cervical region, focused on C1 (atlas)

35
Q

What was the result of BJ Palmer’s focus on C1?

A
  • His hypothesis that a C1 subluxation would cause compression of the spinal cord
  • His HIO technique
36
Q

Who published “Modernized Chiropractic”?

A

Langworthy, Smith, and Paxon

37
Q

What was the purpose of the text “Modernized Chiropractic” by Langworthy, Smith, and Paxon?

A
  • Rejected bone out of place theory; too simplistic of an explanation
  • Favored focus on joint fixation/motion restriction
  • Used to defend chiropractors arrested for practicing medicine without a license
38
Q

Who is the primary advocate of applying the scientific method to chiropractic practice, research, and education?

A

CO Watkins

39
Q

What were some primary beliefs of CO Watkins?

A
  • Chiropractors should generate clinical data and publish clinical research
  • Public relations should be modest and should not masquerade as science
40
Q

Who revitalized the concept of lack of proper joint motion?

A

Marcel and Henri Gillet (Belgian chiropractors) and Fred Illi (Swiss chiropractor)

41
Q

According to Gillet(s) and Illi, how does an injured joint become fixated?

A

Edema develops around strained capsule and tissues leading to joint fixation

42
Q

Gillet(s) focused on the ___ region and spinal biomechanics

A

pelvic region

43
Q

What did Gillet(s) conclude from their focus on the pelvic region and spinal biomechanics?

A

“…one cannot put a vertebra back into place the way one does a fracture or dislocation. What one really does is: to restore the function of a vertebra”

44
Q

Who’s definition of chiropractic is this?

“The art and science concerned with the study and treatment of the mechanics, statics and dynamics of the human body, particularly of the vertebral column and pelvis, for the primary purpose of eliminating neuropathological reflexes and their consequences”

A

Fred Illi

45
Q

What is germ theory?

A

The theory that certain diseases are caused by the invasion of the body by microorganisms (too small to be seen except through a microscope)

46
Q

What did BJ Palmer think about germ theory?

A

Rejected germ theory and focused on subluxation as the cause of all dis-ease and a precursor to disease

47
Q

Who wrote The Science and Logic of Chiropractic?

A

Verner

48
Q

Who said the following?

“…one cannot put a vertebra back into place the way one does a fracture or dislocation. What one really does is: to restore the function of a vertebra”

A

Gillet

49
Q

Verner believed in the impact of chiropractic on ___ as a link to ___

A

impact of chiropractic on the nervous system as a link to other conditions

50
Q

In the 1990s, ___ ___ suggested chiropractic adopt wellness care, doing research guided by efforts to restore homeostatic mechanisms in the body

A

Ian Coulter

51
Q

What sort of research emerged once chiropractic started focusing on wellness?

A
  • Begun to determine to what extent the body is a self-healing organism
  • Departure from the concept of innate in favor of focusing on the neural mechanisms involved
52
Q

What is the inflammation hypothesis by Lantz, in Leach, 132?

A

“Tissue and cellular responses to injury in the spine includes infiltration of histamine, protein derived factors, eicosanoids, proinflammatory cytokines, nitric oxide, degradative enzymes, and substance P, and these pre-stage development of spinal lesions”

53
Q

Who hypothesized that inflammation involves infiltration of histamine, protein derived factors, eicosanoids, proinflammatory cytokines, nitric oxide, degradative enzymes, and substance P?

A

Lantz (in Leach, 132)

54
Q

What are the cardinal/classic signs of inflammation?

A
  • Rubor (redness)
  • Tumor (swelling)
  • Calor (heat, fever)
  • Dolor (pain)
  • Functio laesa (loss of function)
55
Q

Which cardinal signs are usually present with acute inflammation?

A
  • Rubor (redness)
  • Tumor (swelling)
56
Q

Describe the aggressive vascular tissue-level response to acute inflammation

A
  • Infiltration of neutrophils and other leukocytes
  • Consists of the visible signs
  • Capillary wall cells contract and allow exudation

(There might be no actual vascular damage, although there often is)

57
Q

With acute inflammation, ___ and ___ release histamine
What is the effect of this on capillary cells?

A

mast cells and platelets release histamine; capillary cells contract and gaps open

58
Q

What will pass through the gaps in capillaries during acute inflammation?

A

Leukocytes (by diapedesis or transmigration)

59
Q

During acute inflammation, which cells travel to the damaged area and how?

A

Macrophages and neutrophils migrate via chemotaxis (driven by chemotactic stimulants) to phagocytize debris

60
Q

What is the first biochemical mediator in acute inflammation that stimulates the vascular response?

A

Histamine

61
Q

What are the functions of cytokines in acute inflammation?

A
  • Regulate inflammation and immune responses
  • Involved in cell differentiation, replication, survival, and death (apoptosis)
  • Integral to homeostasis
62
Q

What is the function of nitric oxide in acute inflammation?

A

Vasodilation

63
Q

What are the functions of substance P in acute inflammation?

A
  • Vasodilation
  • Involved in cell growth
  • Neurotransmitter associated with nociception and pain, anxiety, stress, and more
64
Q

What are the biochemicals involved in the response to acute inflammation?

A
  • Histamine
  • Cytokines
  • Nitric oxide
  • Substance P
65
Q

Is chronic inflammation an extension of acute inflammation?

A

It can be, or it may begin as a chronic inflammatory disorder

66
Q

Which cells infiltrate during chronic inflammation?

A

Lymphocytes and macrophages

67
Q

How does a tissue react to chronic inflammation?

A

Angiogenesis (new blood vessels) and connective tissue proliferation

68
Q

How long does chronic inflammation last?

A

Months to years, or lifelong illness

69
Q

According to research, is joint cracking more related to cavity formation or bubble collapse?

A

Cavity formation (tribonucleation)

70
Q

According to research in biomechanics, spinal manipulative treatments had what effects?

A
  • Reflex responses far from the treatment site
  • Movements of vertebral bodies in the “paraphysiological” zone
  • Associated with cavitation of facet joints
