CTS prognosis explain each
GOOD
FAIR
POOR
GOOD = early treatment
FAIR = starting signs of mm weakness and/or atrophy
POOR = atrophy, permanent loss of function
Which is not a sign and symptom of CTS:
tingling
nocturnal pain
increase grip strength
atrophy of thenar mm
increase grip strength (decrease)
CTS PT management
splinting (neutral position

TRUE
CTS treatment are?
steroid injection
surgery
ergonomic changes
neurostimulation
acupuncture therapy
Which of these is not a symptom of Sciatica:
Severe unbearable pain
Leg weakness
Heavy feeling
Severe unbearable pain
(Radiating pain)
What nerve is entrapped/compressed in Retroepicondylar Palsy
Ulnar Nerve
(condition is also called Tardy ulnar palsy, Ulnar Nerve entrapment)
T or F
CTS shows a claw hand deformity
FALSE
CTS shows an APE hand deformity
(Claw hand deformity is present in Tardy ulnar palsy)
Froment’s sign is present in what condition
Tardy Ulnar Palsy
Which of these is not a mechanism of injury for Tardy ulnar palsy:
Direct trauma
fx
TBI
TBI
Which of these is not a s/sx of Tardy Ulnar palsy:
mm weakness
mm wasting
numbness
tingling
dull pain
paresthesia
DULL PAIN (shooting pain)
Prognosis for Tardy Ulnar Palsy
GOOD = after surgery (up to 6 mo.)
FAIR = loss of function
T or F: the PT management for Tardy ulnar palsy is surgery
FALSE
PT focuses on conservative tx specifically splinting (claw hand position)
PT management for Sciatica?
Joint mobilization
Exercise
T or F
Males are most likely to have morton’s neuroma than females
FALSE
Female>
Type of splinting recommended for Saturday night palsy
Cock up splint
Sciatica is caused by nerve root compression due to ? and at the level of?
Due to herniation at the L4-L5 or L5- S1
T or F: Steppage gait may present in pt with Sciatica
FALSE Antalgic gait is present (also in Morton’s neuroma)
Nerve fibers that are unmyelinated, slow, and associated with pain sensation.
Type C Fibers
Which of these is not an S/sx of Saturday night palsy
Tingling
Weak wrist extensors
Wrist drop
Paralysis
Sharp burning pain
None all are corect
Compression of the Radial nerve in the arm
May lead to segmental demyelination
Saturday night palsy
T or F
In Saturday night palsy the griping problem is due to the weakness of the wrist
FALSE weakness is not always the case, griping problems may be caused of the wrist drop
Entrapment leads to thickening of nerve structures and demyelination
Morton’s Neuroma
Wrist drop is present in what PNI condition?
Saturday night palsy
Which of these is not an S/sx of Morton’s Neuroma
Burning, tingling sharp pain during walking
Difficulty sitting
Paresthesia
Difficulty in long sitting
Nocturnal pain
Difficulty in long sitting
Consistent, severe unilateral Shoulder girdle pain is consistent with what PNI condition?
Paronage-Turner Syndrome
A process of nerve degeneration that occurs after a nerve is cut or crushed.
Wallerian Degeneration
A rare and idiopathic PNI condition
that affects the LMN of the brachial plexus or indiv ner or indiv branches
Parsonage-Turner Syndrome
Common entrapment neuropathy in the forefoot,
What is the condition and in what interspace?
Morton’s Neuroma
3rd toe interspace
The outermost layer of a nerve, providing tensile strength and elasticity.
Epineurium
Transmits signals from the CNS to the body.
Peripheral Nerves
The fibrous covering that surrounds the axon within a nerve.
Endoneurium
Nerve fibers that are heavily myelinated, fast, and associated with touch sensation.
Type A Fibers
A condition resulting from damage to peripheral nerves, often presenting with sensory and motor symptoms.
Peripheral Neuropathy
What is Bell’s Phenomenon?
The inability to close the eye d/t bells palsy
so the eye rolls upwards instead
Bell’s Palsy occurs due to the compression of what nerve
CV VII
Infllamation and swelling that compress the nerve and potentially cause demyelination and axonal damage to the auditory canal
Bell’s Palsy
A hereditary motor and sensory neuropathy
that is due to damage to the peripheral nerves
Charcot-Marie Tooth DSE
Whoch of these is not an S/x of Charcot-Marie tooth DSE
Hypo reflexive
Strong distal mm
Foot drop
Steppage gait
loss of sensory
Strong distal mm (it is weak)
Hyperglycemia-Induced Effects & vascular changes leads to nerve damage and loss of axon
Diabetic Neuropathy
