And does twisting your back aggravate your symptoms?
Has a significant positive indication of a domino symptoms of musculoskeletal origin combination of these questions gave96% specificity
Asterixis
“Liver flap” is observed by having the patient extend the arms, spread the fingers, extend wrist and observe for the abnormal “ flapping” tremor at the wrist
If a tremor is not readily apparent ask the client to keep the arms straight while the therapist gently provides overpressure into wrist extension. Asterixis may also be observed when releasing the pressure in the arm cuff during blood pressure readings.
Sports hernia
Or hockey hernia or athletic pubalgia
Patients experience a “weakening or tearing of the transversalis fascia, conjoined tendon, and/or internal oblique fibers, creating an inside out hernia within the dorsal wall of the inguinal canal.
Associated with twisting, turning or directional changes in speed causing the hip to move into abduction adduction or extension
Ballistic movements such as frequently observed in soccer and ice hockey players leads to shearing at the pubic symphysis and resultant stress on the above structures
Pectineus tendinopathy
Presents with greatest pain provocation during resisted hip flexion and resisted hip adduction with the hip positioned in 90 degof flexion
Cpr for responding to mechanical cervical traction
Age >55
+ shoulder abduction test
+ ULTT A
Symptom peripheralization with lower cervical PA motion testing
+ neck distraction

strength of evidence: V
expert opinion
p value definition
- comparing two or more groups
tells you the probability that the difference between groups occurred due to chance
almost always settle for 95% certainty
–which means any pvalue lower than 0.05 is statistically significant
alpha value
the point at which the researchers decide the results are statistically significant is called alpha level
ex a= 0.05 any pvalue less than 0.05 is statistically sign
type I error
- backing a loser
- concluding that their is a significant difference when there is not
typer II error
- missing a winner
- when researchers do not find a statistical sign differences when in reality there is. often due to too few subjects so they are unable to detect differences.
effect sizes
–” how much better?”
0.8 and up = large
0.5 - 0.799= moderate
0.2 - 0.499 = small
below 0.2 = trivial
test reliability
Kohen kapp: K
- runs on scale from 0-1 0 = no reliability <0.4 = poor 0.4-0.6 = fair 0.6-0.75 = good >0.75 = excellent 1 = perfect reliability
positive likelyhood ration
how much you should increase your suspicion of a certain condition based on pos test result
> 10 = large shift in prob
5- 10 = moderate shift towards diagnosis
<5 = small shift in probability
1 = no change
negative likelyhood ratio
how much you should decrease your suspicion of a certain condition based on neg test result
<0.1 large shift away from diagnosis
0.1 -0.2 moderate
>0.2 = small
1 no change
hawthorne
- quasi experiments outside of hawthorne illinois
- conclusion subjects that know they are being observed as part of a research study tend to work harder that they would otherwise.
john Henry effect
- railroad worker. worked so hard to beat steam drill that he died in process
- control group perceives that they are disadvantaged compared to experimental group that they work harder than they otherwise would have. they might seek out other treatments or perform more self treatments on their own
best thing to do would be to blind studies to knowing if they are in control group or experimental group
Pygmalion / rosenthal
- pigmelion effect describes how the expectation of those in authority shapes the outcome of their subjects.
this is why we blind clinicians
red flags associated with a back related tumor /Cancer
- constant pain not affected by position or activity
- age >50
- hx of CA
- failure to improve in 30
- no relive with bed rest
- unexplained weight loss
at least 2 or 3 together might call for referral out
types of cancer most likely to metastasize to spine
PT. BARNUM loves kids
- prostate
- thyroid
- breast
- lungs
- kidney
history of these cancer should increase suspicion
-ESR - erythrocyste sedimentation rate blood test
- ESR >20 : starts suspecting
- ESR>50 positive likelyhood ratio of 19.2 for CA

24 items in 3 categories
0-100 ; 0 represents the highest level of knee function
Koos index
Knee injury and osteoarthritis outcome score
Extension of womac and designed to be more responsive to those of a higher activity level.
The questionnaire asks about pain other symptoms activities of daily living, function in sport and recreation, and quality of life. On a 0 to 100 scale, 100 represents best function. It has been validated on patient status post total knee receiving physical therapy. The minimal detectable change is dependent on section pain is 22 stiffness is 29, and physical function subscale is 13
Knee outcome scale KOS

Useful with patients following arthroplasty and lowe extremity conditions of musculoskeletal origin
Measuring knee joint effusion
0 - none. Milk out swelling distal to proximal several times. Sleep proximal to distal on the lateral side and view the medial sulcus for return of swelling
Trace- Milk mediately sweep laterally, small amount back
1+ : You can milk out the swelling and it does not return on its own but returned with a lateral sweep
2+ : You milk out the swelling and it returned immediately to fill the pouch
3+ you cannot milk out swelling
Special test for
