PTE section 1 done Flashcards
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.
Objective
Somatic Observation, palpation, it is reproducable.
Visceral Cannot reproduce thepain that they have.
Response to PT
Somatic yes,
Visceral, no.
- Dizziness/syncope (fainting)•Fever
- Diaphoresis (unexplained)
- Night sweats
- Pallor
- Nausea & Vomiting
- Fatigue
- Weakness
- Weight loss
- B & B2,
Comstituitional signs
When would we want to ask CS?
When we are concerned that perhaps it is not somatic. Because somatic is very muscles and bones. Not visceral.
Onset
• Insidious vs traumatic • Not always obvious • Ie prolong sitting incorrectly causes minor trauma• Ie running with poor body mechanics • Explain mechanism of accident • When did the pain start?
Quality
- Find what words the patient to describe their pain to differen-tiate between
- Acute vs chronic pain
- Neurologic pain
- Somatic vs non somatic pain
- What words would a patient use?
- Systemic (Knifelike, Cutting, Throbbing, Bone pain)
- Somatic (Achy, Stiff, Sharp)
Provoke
• Is the pain constant vs intermittent?
• What increases the pain?
Can also teach the movemnt pattern, to be able to dknow
• Attempt to find a pattern what motions to avoid.
• Ie. Is it a trunk flexion the pattern that is bother-
ing them?
• Ie. Is knee flexion activities the pattern is bother-ing them?
Region
• Have the patient point to the pain, and indicate if it is su-perficial or deep
• Somatic pain is usually specific, but it can be vague.
• Systemic pain is usually vague
• Ask if they have pain anywhere else2,pg119
• Why should a PT be concerned if a patient has radiating
pain?
Timing
- What time of day does it hurt more?
- OA usually is painful for the first hour of day, due to stay-ing still while sleeping
- Will also show the severity of their pain
You go into the PMH and all of their sunpbjective history, and if the history and the subjective told you anything that made you guess at visceral you should ask about constituitional signs, and now we should have a very good idea if it is somatic or not, if you think that it is somatic, so then go and perform either an upper quadrant or a lower quadrant screen, there are only two, and if all the signs pointed to a specific sysytem, then you will go and perform a specific sysytem’s screen.
.
What are red flags?
• Red Flag- tells the examiner that a symptom requires immedi-ate attention, to perform a screening, request a test or refer to
the MD 2,
• The mere presence of one flag does not indicate an immediate reaction2,
Remember musculoskeletal presentation
- A clear history of trauma (may be repetitive)• Predictable pain pattern
- Gets better with time
- Resolves in appropriate time
These may not be red flags, they are usuall msk
What are some red flags?
• Can be divided into the following categories
- PMH, their past
- Risk Factors, what they have socialy
- Clinical presentation, what they are showing now
- Constitutional Symptoms, side effects of visceral
- Pain patterning, the specific areas of pain and types of pain that visceral amd or somatic usually presents itself with
Red Flags: PMH
•Personal or family hx of CA
•Recent infection (last 6 wks)
•Recurrent colds or flu
•Recent hx of trauma (w/o appropriate medical follow Risk Factors
up)
•MVA, fall, or a minor trauma if elderly (due to OP)
These past medical history can point to somatic, like by OP or to systemic diseaes like by CA.
Red Flag: Risk Factors
Certain factors will put a person at greater risk in acquiring certain diseases, such as: • Substance abuse • Tobacco use • Age • Gender • Body mass index (BMI) • Exposure to radiation • Alcohol abuse • Sedentary lifestyle • Race/ethnicity • Domestic violence • Occupation
Red Flags: Clinical Presentation
- Insidious onset with unknown etiology
- Sx unrelieved by PT or get worst
- 10% weight loss or gain from 10-21 days, w/o ptknowing why
- Sx unrelieved by rest or change in position
Red Flags: Constitutional symptoms
- Dizziness/syncope (fainting)•Fever
- Diaphoresis (unexplained)
- Night sweats
- Pallor
- Nausea & Vomiting
- Fatigue
- Weight loss
- B & B
Red Flags: Pain Patterning
• Night pain (unrelieved by re positioning)
• Pain is constant and intense
• Described as throbbing, knifelike, boring or deep
aching
• Pain associated with other sx of visceral GI
• Change in pain with food intake or medication use(immediate or several hours later).
• Pain that is poorly localized
Things that mechanical cannot account for.
Additional Red Flags
• Originally relieved by rest however with time
this no longer helps, is it betting worse
• Sx’s out of proportion to injury, it is not making sense according to what we expect through our physical findings
• Sx’s lasting longer than normal, why is a somatic injury lasting this long?
• Unable to alter the sx’s during exam, we cannot do anything for it?!
• Change in ms tone if the pt has a neuro dx, its so bad that the tone of the muscle has indeed been chalenged
• Sx’s does not fit expected musculoskeletal or neu-romuscular dx, then what could it be.
I
What must be considered before a PT be-comes alarmed with the presence of a red flag(s)?
• Whole body must be taken into considera-
tion.
• Can the red flag be explained for a ms cause •Multiple red flags and no signs of somatic
pain that is a clear indication of danger
What should a PT do in the presence of a red flag(s)?
•Perform a screen
•Don’t call MD first, must screen in orderto give MD more info.
•Unless it is an emergency don’t do a
screen, call 911
•Screen should be appropriate for correspond-ing symptoms
•Ie. Pt c/o CP, Pain down Left arm, PT should to do a Cardiac screen
If all of the visceral signs and symptoms point to a specific systemic disorder, then we need to go and do that system’s screen
•A screening process is done during the interview, AND must be verified with
the physical examination
• Cannot make a conclusion until the objective is done
Why do we a ask pt for their social history?
• Each component of a pt’s social hx exposes a pt to various health risks1,
Examples
• Repetitive strain at work, can we teach them how to do it differently, or can we guess at why they are injured the way they are, or while wea re treating them for this one issue, can we prevent a future issue.
• Dangerous jobs, can they get a new job
• Customs that conflict with PT intervention, will we be able to perform the interventions in a manner that will be comfortable by the patient.
