Cards

Term
McKenzie believed there are several predisposing factors related to the occurence of LBP (3)
Definition
sititng posture
loss of extension ROM
Frequency of flexion
Term
3 basic components of MDT
Definition
Mechanical dx
Mechanical tx based on mechanical dx
Prevention of recurrence
Term
How is prevention of recurrence achieved
Definition
emphasize pt responsibility to follow through with treatment rx
exploring pt generated forces fully before applying PT forces
Term
MDT Exam: part 1 of 3
Definition
posture is addressed
Term
MDT Exam: part 2 of 3
Definition
single AROM assessed to determine quality and quantity and presence of deviations during movement
Term
MDT Exam: part 3 of 3
Definition
repeated mvoement testing key to the exam process
Term
purpose of repeated movements
Definition
affects of loading on the spine in different planes assessed
centralizaoitn/peripheralization important guides during assessment
Term
Loading progressing of the MDT exam (3)
Definition
WB to NWB
Saggital to frontal to transverse
Dynamic (cyclical loading) is tested first followed by static laoding if needed
Term
4 MDT classifications
Definition
postural
dysfunction
derangement
other (SIJ, Hip, non-mechanical)
Term
when are pt's classified into an MDT classificaiton
Definition
following repeated movement assessment
Term
Postural Syndrome: what produces pain
Definition
abnormal stress on normal tissues
Term
Postural Syndrome: symptoms are NOT produced by what
Definition
repeated movements
Term
Postural Syndrome: symptoms are produced by what
Definition
sustained posturing only and relieved by posture correction
Term
Postural Syndrome: where/frequency of pain
Definition
local/intermittent pain
Term
Postural Syndrome: type of onset
Definition
insidious
Term
Postural Syndrome: is a result of what
Definition
sustained loadign of tissues during end range positions
Term
Postural Syndrome: result of sustained loading of tissues during which positions
Definition
end range positions
Term
Postural Syndrome: there is no (3) with repeated movements
Definition
deformity
loss of motion
pain provocation
Term
Postural Syndrome: 5 aspects of pain
Definition
gradual onset
local
symmetric
never referred
onset usually occurs after 15 minutes with sustained end range positioning only
Term
Dysfunction syndrome: ______ stresses on ______ tissues produces pain
Definition
normal stresses on abnormal tissues produces pain
Term
Dysfunction syndrome: associated with what type of motion loss
Definition
symmetric or asymmetric
Term
Dysfunction syndrome: what type of onset?
Definition
insidous
may have of hx of previous injury
Term
Dysfunction syndrome: 2 aspects of pain
Definition
Local pain (Except ANR)
occurs at full end range only and not worsened with repeated mvmts
Term
Dysfunction syndrome: how are the subclassifications named
Definition
direction of movement restriction
Term
Dysfunction syndrome: how are the subclassifications named
Definition
direction of movement restriction
Term
Dysfunction syndrome: 5 subclassifications
Definition
flexion dysfunciton
extension dysfunction
side-gliding dysfunction
multidirectional dysfunction
ANR
Term
Derangement syndrome: is thought to be the result of what
Definition
displacement or alteration in the postioin of joint structures
Term
Derangement syndrome: originally based on what model
Definition
theoretical disc model
Term
Derangement syndrome: old terminiology
Definition
IVD anterior and posteiror derangements with posterior divided into 6 subcategories
Term
Derangement syndrome: Current MDT terminology
Definition
derangements as reducible or irreducible and then describes pain location adn or presence of a deformity
Term
Derangement syndrome: pain location/intensity
Definition
quick changes
Term
Derangement syndrome: pain during movement?
Definition
yes
Term
Derangement syndrome: presence of a deformity
Definition
may or may not
lateral shift, kyphosis, accentuated lordosis
Term
Derangement syndrome: what increases as pain centralizes or abolishes
Definition
ROM
Term
Derangement syndrome: symptoms better or worse as a result of what exam procedure
Definition
rptd mvmts
Term
Derangement syndrome: onset
Definition
acute or insidious
Term
Derangement syndrome: pain patterns
Definition
local or referred
Term
Derangement syndrome: pain location descriptions (4)
Definition
central
unilateral
symmetric
asymmetric
Term
Derangement syndrome: what is the guiding response for this syndrome
Definition
centralization or peripheralization
Term
the "other" categories for MDT
Definition
non-mechanical LBP, inconclusive
Term
requirements to classify pt as Non-mechanical LBP
Definition
rptd mvmts have no effect or no directional preference found
Red flags
Waddel's signs
Term
requirements to dx pt as inconclusive
Definition
rptd mvmts affect symptoms but no directional preference or consistent pattern is observed during exam
tx symptomatically and then reassess
Term
MDT interventions: what is key to a successful outcome
Definition
posture correction
Term
MDT interventions: progression of forces
Definition
mid range to end range, to end range with over pressure
Term
MDT interventions: when should PT generated forces be implemented
Definition
pt has plateaued or no effect with self generated forces
Term
MDT interventions: postural syndromes
Definition
correct faulty posture and pt education
Term
MDT interventions: dysfunction syndromes
Definition
move into the restriction in an attempt ot elongated shortened tissues
Term
MDT interventions: derangements: what types of techniques should be utilized
Definition
symmetrical techniques
Term
MDT interventions: derangements: when should asymmetrical techniques be avoided
Definition
symmetric symptoms (acute kyphosis)
Term
MDT interventions: derangements: why should asymmetrical techniques be avoided with symmetric symptoms such as an acute kyphosis
Definition
may convert a posterior derangement into a posterolateral derangement
Term
MDT interventions: derangment: when are asymmetricla techniques used
Definition
asymmetric derangments/pain patterns
Term
MDT interventions: the direction of tx is governed by what
Definition
centralization/peripheralization phenomena
Term
in most cases, no mvmt should be performed that causes pain referral to peripheralize except
Definition
ANR
Term
MDT interventions: derangement syndromes: 4 objectives of tx
Definition
reduce derangement
maintain reduction
recovery of function
prevention of recurrence
Term
MDT interventions: derangement syndromes: reduce derangement
Definition
correct acute deformity if present
utilize mid range to end range to end range with overpressure progression of forces
Term
MDT interventions: derangement syndromes: recovery of function: meaning what
Definition
reintroduce flexion
Term
MDT interventions: derangement syndromes: prevention of recurrence
Definition
perform extension whenever in prolonged flexion
Term
MDT interventions: derangement syndromes: when is it safe to test if the pt can flex forward again
Definition
48 hrs s symptoms
Term
MDT interventions: derangement syndromes: if the pt has gone 48 hrs s symptoms, when should you test flexion
Definition
not in the morning
Term
MDT interventions: derangement syndromes: pt has gone 48 hrs s symptoms, and are seeing you for an afternoon visit, what is the progression to see if they can reintroduce flexion
Definition
EIL 10x full ROM s pain
FIL 10x full ROM s pain
EIL 10x full ROM s pain
if EIL not at full ROM don't progress
if FIL is not with full ROM or has pain, not ready for flexion
if 2nd EIL not at full ROM, pt not ready to flex
