Fundamentals of MSK Flashcards
What is a differential diagnosis?
Systematic process used to identify the most probably dx from a set of possible competing diagnosses
When does a differential diagnosis begin?
In the hx with a working dx
What does the differential diagnosis direct?
The POC
What should we do when we begin our examination?
Obtain informed consent
What should we know about informed consent?
Specific
benefits and risks
offer options
full understanding
What does a history provide us with?
A mutual patient focused relationship
What should our history questioning begin with?
Open ended questions
When should we use closed ended questions in our history?
To clarify and verify
What kind of questions do we not want in our history?
Leading questions
What does SINSS stand for?
Severity
Irritability
Nature
Stage
Stability
Why do we use SINSS?
Helps determine the vigor and extent of physical exam and intervention as well as prognosis
What is minimal severity?
0-3/10
intermittent pain/limitation/medication
What is moderate severity?
4-7/10
Intermittent and constant pain/limitaiton/medication
What is maximal severity?
8-10/10
constant pain/limitation/severity
What about sleep are we concerned with?
If it is interrupted, influence of positional changes
What do we need to know about medications and supplements?
Dosage - OTC or precription
Frequency
Results
What is minimal irritability?
Easing > aggravating activities
Easier relief and slower aggravation
What is moderate irritability?
Easing = aggravating activities
Similar relief and aggravation timing
What is maximal irritability?
Aggravating > easing activities
Easier aggravation and slower relief
What is a mechanical issue?
Symptoms respond to movement
What is a non-mechanical issue?
Symptoms do NOT respond to movement - RED FLAG
What is nociceptive pain?
MSK or viscerogenic
vague, dull, achy
What is neuropathic pain?
Nervous tissue compromised
paresthesias and/or numbness
What is nociplastic pain?
Mismatched and heightened pain perception
pain that is inflammatory is ….?
sharp
What do patient characteristics such as psychological factors influence?
pain perception
What is a suspicious MSK red flag S&S?
unwillingness to move or splinting after trauma
What qualifies a condition as being acute?
less than 3 weeks
What qualifies a condition as being sub-acute?
3-6 weeks
What qualifies a condition as persistent?
More than 6 weeks
What is high sensitivity better at?
RULING OUT
What parts of the social history should we be concerned with?
Smoking
alcohol
drugs
work
When does observation happen?
From introduction through intervention
What may we observe during conversation?
Slurred speech, hoarseness
What are some structural characteristics we may observe during observation?
Body type, postures, swelling, skin markings, hair quality, asymmetries, othotics, etc.
What is a red flag that we may see during observation?
deformity after trauma
What is our general assessment?
Scan or screen
What is a biomechanical exam?
Greater detailed assessment based on scan findings
What are symptoms?
Reported by/for the patient
What are signs?
Objective; measured by the clinician
Can symptoms be present without signs or impairments?
Yes
What are the 5 purposed of a scan?
- assess for red flag S&S
- assess neuro status
- determine if symptoms are referred or radicular
- assess severity of condition
- identify need for more in-depth biomechanical exam
What does active ROM assess?
Willingness to move, ROM, integrity of contractile and inert tissues, pattern of restriction, quality of motion, and symptom reproduction
What does passive ROM assess?
Integrity of inert and contractile tissues, ROM, end feel, and sensitivity
What does resisted testing assess?
Integrity of contractile tissues
What does stress testing assess?
Integrity of inert tissues
What does neurologic testing assess?
Nerve conduction
What should we scan first without recent trauma?
spine first
What do we scan first with recent trauma?
involved areas first
What is the purpose of selective tissue tension testing?
discerning contractile from non-contractile tissue integrity
What are contractile tissues?
muscles
tendons
fascia
What are non-contractile tissues?
everything else such as cartilage, bones and ligaments
What are the 3 components of a STTT?
A/Prom with overpressure
combined motions
Resisted testing
What do we observe with ROM?
Quantity and quality
What is WNL ROM?
full, pain free, coordinated motion and smooth curves
What does aberrant motion indicate?
joint hypermobility/instability
What do sharp curves or fulcrums in the spine indicate?
Impaired motions
Full quantity of ROM is not always synonymous with …
Normal or efficient motion
What are essential or basic ADLs?
Walking, reaching, squatting, bending, turning, etc.
What are some higher level ADLs?
Lifting, throwing, jumping, running, etc.
What does improved pain/function with repetitive tests indicate?
Possible inhibited muscle, disc injury, etc.
What does worse pain/function with repetitive tests indicate?
Acute injury/irritation
What can a inhibited muscle be due to?
Pain
swelling
disuse/immobilization
joint laxity
What is an end feel?
What the clinician feels at the end of a movement
What type of tissue is indicated if the same pain occurs in the same direction of AROM and PROM?
Non-contractile tissue
What type of tissue is indicated if PROM is similarly restricted as AROM in the same direction?
Hypomobility, protective guarding or a shortened muscle
What is indicated by PROM being significantly greater than AROM in the same direction?
Hypermobility/instability
When should we perform combined motion?
If uniplanar motions don’t provide much if any guiding information
What kind of motions are combined motions usually??
Circumductions
What does a consistent block indicate?
Hypomobility so follow up with accessory motion tests
What does an inconsistent block or crepitus indicate?
Hypermobility/Instability so follow up with stability tests
What does opposing spinal quadrants being consistently blocked indicate?
A fibrotic joint so follow up with accessory motion tests
How long do we hold manual muscle tests?
At least 3 seconds
