quiz ch 19, 57, 37, 38 Flashcards
Once adjustment has been selected, what are the patient and doctor variables that can be controlled to modify treatment delivery
- posture
2. initial condition
what can cause buckling
- static position then you put a load on it
- load at 500 lbs/sec
- vibration
how can you differentiate between mobilization from high velocity low amplitude procedures
- look at velocity vs. tissue
- slow acting mob -viscoelastic, and low end of stiffness
- rapid procedure- viscoelastic quickly and relys on stiffness
how tell grades apart
define the mechanism of action for each biomechanical classification of treament procedures
- cpm, flex distraction, garde 1 and 2 - visocelastic
- grade 3 viscoelastic and midrange stiffness
- grade 4 and hvla hammers- stiffness
how does a reductionist view of clinical chiopractic assist patient care
break down into mechanistic details so helps patient
ch 57 whats estimated rate of post SMT CVA (stroke)
1/400,000 = 5.8 million
whats most common vascular lesion associated with cervical SMT
diessection of vertebral artery at that cervical vertebral level
what are the known RISK FACTORS associated with dissection of cervical cerebral blood vessels
stenosis of post inf. cerebellar a hyperplasia medical cystic necrosis CT abnormalities GENETIC DISORDERS OF COLLAGEN INHERITED FACTORS hyperhomocysteinemia UPPER RESPIRATORY TRACT INFECTIONS precurosor lesions TRAUMA
what is the clinical presentation of a patient suffering from vertebral artery dissections
SUDDEN SEVERE PAIN IN NECK DIFF FROM ANY PAIN BEFORE DIZZYNESS drop attacks (IOC) dysarthria (speech difficulty) dysphagia WALKING DIFFICULTIES NAUSEA (VOMIT) NUMBNESS ON ONE SIDE OF BODY AND FACE nystagmus hemianesthesia CONFUSION visual field distrubance
what are the neurological conditions that should be watch when tx patient with lumbar/cerv disc syndrome
radiculopathy
myelopathy
cuada equina (emergency referrel)
what are the contributions of manipulation
meric system
major and minor subluxation
toggle-recoil adjustments
instrument assisted adjusting
difference between a graded oscillation and manipulation
speed dand force of procedure delived
mobilization/graded oscillation: within patients ability to resis manipulation
manipulation is delivered with a speed and force patient cant resis
difference between impulse-based model and non impulsed based model
impulse base referes to reflex distubrances
non impulsed based refers to nerve compression effects
list the models that are in common use when it comes to objectives of chiro adjustment
static vs dynamic model lesion model mechanical vs neurological model anatomic model systems model physiological model pathological model wellness model health model
what are teh grades of mobilization according to maitland
grade 1 little force in begining of range
grade 2 greater depth, begining of range
grade 3 greater depth and end range
grade4 small depth and end range with little osscilation
grade 5 paraphysiologic range
which professions use high veolocity low amp thrust for treating muscoloskeletal problems
chiro
osteopath
medicine
physical therapy includes HVLA
differences between long or short lever and a general or specific contact
- short and specific (SP, TP) localizes force to singl joint
- long lever and general spreads to multiple joints
what terms is the adjustive force defined
impact kinectic energy (mass and velocity) or clinician and mechanical resistance to deformation ( stifffness and elasticity) of both patient and clinician
what is cavitation and significance
cav is when joint is taken beyond elastic barrier creating sudden yielding of jt as it enters paraphysiological space
liquid in container turns into a vapor bubble and pops
significance: temporarily increase pass rOM, increase jt space, with 20 min refractory period
how does assisted prestress differ from a resisted presetress in delivery of HVLA thrust
assisted prestress has segmental contacts on superior vertebrae of the dysfunctional motion.
applied prestress is in direction of thrust
adjustive vectors direct to produce movement of superior vertebrae
resisted presetress has segmental contact on inferior vert of dysfunct segment, applied prestress in dirrection opposite of thrust, adjustive vectors directed to produce movemnt of inferior vert
a assisted mechanism affects joint below segmental contact while resisted affects joint above segmental contact
