Exam 1 Major Models and Hypotheses of Chiropractic Subluxation Flashcards
(56 cards)
A branch of mechanics that studies the relationship between the forces acting on the body and the changes they produce in the motion of the body
Kinetics
Who is the chiropractic pioneer in biomechanics
What was his concern
- Dr. Fred Illi
- skeletal framework (spine & pelvis) = a unit where weight bearing, posture, locomotion
tie into
nervous & vascular systems, psychology, emotions
Who associated with the concept…
Hypomobility in a motion segment leads to compensatory hypermobility, particularly in motion segments immediate/ adjacent to fixed segment
Jirout, Kirkaldy-Willis
A lack of mobility in any segment due to any cause will result in compensatory hypermobility in the segments above and or below is the _____ ______
compensation reaction
According to Jirout,
What happens when an initial block is a highly mobile segment
Can it be fixed
- compensatory hypermobility is DRASTIC
- if factors noted in time, osseous changes CAN be avoided
A characteristic of affected segments is displacement of the normal axis of rotation in one or more planes …
is termed as
Change in Central Axis of Motion
- attributed to Kapandji
Who wrote the book on modernized chiropractic?
Smith and Langworthy who were students and
Paxson
“A subluxation is a condition in which the exact relation between the articulating surfaces of bones has been altered from normal, the articulating surfaces still remaining in partial contact”
is a definition from
the modernized book of chiropractic
According to the modernized book of chiropractic, a simple subluxated vertebra differs from a normal vertebra only in its
- field of motion and center of its field of motion
- various positions of rest
According to the book of modernized chiropractic,
“positions of rest”
refers to what
positions assumed by bones while the body maintains certain poses (postures)
According to the book of modernized chiropractic,
when a change takes place, everything is changed much like a …
wheel with its hub off center
- too great on some directions and too small in others
The hypothesis that facet joints (z-joints) of affected segments demonstrate a loss of joint play is attributed to
Mennell
The loss of joint play represents and is associated with
- represents the amount of capsular laxity/ joint
- associated with reduced active or passive ROM, muscle hypertonicity and pain articularly
How can loss of joint play be corrected, according to Mennell?
HVLA thrust adjustment
The concept that vertebral malposition and aberrant motion are almost always concomitant findings
(misaligned segment/ 1 plane = segment in wrong place)
is called
positional dyskinesia
- Suh, Plaugher
“No adjustment should be administered to an apparent positional dyskinesia without concomitant evidence of a decrease in mobility at that articulation”
is a statement from
the Textbook of Clinical chiropractic
Plaugher also states,
“There is ____ scientific evidence that adjustments affect the positional dyskinesia component of the subluxation complex”
little
What can we tell patients regarding dynamics and kinesio-pathology?
the subluxation process occurs in a body that is seldom at rest (static)
What are we concerned with?
abnormal patters of movement AND the stuck places
What happens when one bone doesn’t move enough
another one will move too much
True or false
The chiropractic adjustment has been shown to restore normal joint play to affected segments
true
If a vertebra is out of place it will not move normally and if it’s not moving normally…
it will be found in the wrong place sometimes
In subluxation associated degeneration, what models are there?
- 4 phase model
- 3 phase unified model
What does the 4 phase model chart?
the progression of the hypothesized biomechanical effects of uncorrected VS and offer empirical responses to adjustments
