PTE section 1 done Flashcards
(120 cards)
4 key examination findings for identify-ing CA
•Weight loss
•Inadequate relief with rest
Personal hx
•> 50 y/o
Liklihood ratio, above what is very likely to be and below what is very likely to not be?
Above 10 and below .10
When all 4 key examinations for CA findings are present
•Sensitivity = 1.0 very chance to not have
•Specificity = 0.60 some chance to have
Positive LR = 2.5 not ten so low likelyhood to have
Negative LR = 0 very likely to not have
So the sensitivity and the NEGATIVE LR match very well here, that both indicate that the person is not able to have cancer.
(CPRs)
Clinical Prediction Rules
You go step by step to be able to figure out the pain or dysfunction that the person is having.
Tingling in their hand, local, CTS, or from their neck, Cervical Radiculopathy
And we will get into these, to be able to figure them out in future chapters of the PTE.
What structure is the most sensitive to pain?
1- Periosteum and joint capsule
2- Subchrondal bone, tendons, and ligaments
3 - Muscle and cortical bone
4 -Synovium and articular cartilage
It seems that the deepest to the most superficial is the way to go and decide if it is to have the most or to have the least amount of innervations.
What are the characteristics of visceralpain?
- Poorly localized (Does not have a directpathway)
- Not always reproducible (Bc the pain is not mechanical in nature)
- Corresponds with systemic sx’s (N & V, fever etc)
Any pressure to the dia-
phragm will cause pain to its innervation level of C3-5
(Shoulder Pain)
Central contact of the dia-phragm causes
shoulderpain
Peripheral contact to the diaphragm
ipsilat-eral costal margin pain
PNS pain is usually
reproducible
• Mechanical in nature, ie “Pinched nerve”• More common
CNS pain is
not reproducible
• Not mechanical
• Not very common
• Elicited by malfunction of the nervous system itself
• Due to alterations of efferent and afferent info
Can you really reproduce pressure on the spinal cord or on the brain?
Quality of neuropathic pain
Sharp
Shooting, burning,
Tingling
Producing electric shock
Ever have that pain in your lower leg that was coming from whenever you extended your leg? That pain… What was it like?
Therefore a goal of the PT is to__________pain to determine if the sources is due to musculoskeletal dysfunction.
Reproduce
What happens if the pt tells you that they have pain with movement but when you try to reproduce that pain you are not able to?
Maybe the pain is from repetitive motion so you will need to try to keep kn doing it.
But maybe there is pain with combined motions which we shall address in the neuronsection… Hang on.
What spinal motion(s) decreases the intervert foramen?
Extension
Lateral Spinal Stenosis
- Narrowing of the inter-vert foramen• Can cause compression of the spinal nerve
- Common if > 60 y/o
We see the idea of an elderly.
Keep these ideas in mind when trying to tabulate the different pains that can result. For example, young people do not get stenosis, usually.
Sign and Sxs of stenosis
- Lower back pain (LBP), that the tightening happens at the lower back area can give us the pain in the lower back area.
- Numbness and tingling in the feet, because the nerves that go to our feet are the ones that are being comoressed
- Decreased muscle stretch reflexes, if we consider this a LMN issue, so the reflexes are to be lessened.
- Altered sensation, as we did say earlier that the nerves are being pinched
- Motor weakness in the legs, because the nerves in the legs are being pinched
- Increased with extension type of activities, this is how the vertebral canal is to become even more occluded.
- Relieved by flexing the spine activities, because now the tightness of the vertebral canal is to be relieved.
What are the sign and symptoms of HNP?
• History of flexion type of
activities, because this is what goes and causes the nucleas to spill out
• Typically 25-45 y/o, the younger people have the nucleas to spill out
• Uncommon in older
population bc fluid por-
tion of nucleus becomes
more fibrous with age
• But can be extension
also, depends on how
acute
- LBP, because it should not matter if the nerve is being pinched due to the compression from the vertebral canal as from the stenosis, or from the nucleas that is spilling anterior and again is now compressing the spinal cord.
- LE pain, so another reason why there should be pain.
- Increased with flexion ac-tivities, as we have explained
- Parathesias/altered sen-sation, just like all nerve compressions.
But with altered sensations we need to know if it is brain or at any of the other joint that come to the end area, for example, the hand, is it the brain, is it the neck, is it the shoulder, is it the elbow, is it the wrist, which the wrist is called CTS, and there are also dura tests that can be done.
• Motor weakness
What functional activities require flexion?
- Sitting
- Bending forward
- Sleeping
- In fetal position
Is somatic insidiuos, is visceral insidiuous?
Somatic an be either trauma tic or it can be insidiuos.
Visceral, usualy is insidiuous, but it can also be traumatic.
Provoke for somatic and visceral.
Somatic usualy has a pattern, but visceral usually does not have a pattern.
Quality for somatic and visceral.
Somatic is Sharp or dul for
somatic. Nerve it is shooting or tingling,
Visceral Trobbing, searing. Knife stabbing, can be sharp.
Region for somatic and visceral
Somatic More specific but acute is more diffuse.
Visceral More diffused.
Severity
Can be bad or little for both somatic or visceral.
