25
Once you find there is nerve damage, what is the next step
Find out what part of the nervous system
26
What are the 4 main leg pain qualities of radicular syndrome?

What two things may cause nerve root compression
Herniated disc | Spinal stenosis
30
What are the results of nerve tension tests in radicular syndrome
often reproduce leg symptoms
31
Nerve tension tests (SLR, XSLR, Braggard, Bowstring, Bonnet, Slump, Dreyerle) provoke and inflamed peripheral nerve (aka ________) or it’s nerve roots (aka ________)
Neuritis | Radiculitis
32
SLR tensions what nerve roots and peripheral nerve? what is a hard and soft positive test?
L4, L5, S1 Sciatic nerve Hard- create or aggravates lower extremity pain below knee Soft - above knee
33
SLR is good at testing for patients with ______ but has a poorer sensitivity for What additional 3?
Posterolateral disc herniations - spinal stenosis - spondylolisthesis (sensitivity 14%) - midline and medial disc herniations
34
What is braggard test?
Patient supine, leg raised, dorsiflex foot
35
What is bowstring test
Patient supine, knee flexed, apply pressure to tibial nerve in popliteal fossa
36
What is bonnet test
Patient supine, leg raised, internally rotate and adduct hip
37
What is maximum SLR test
Dorsiflex, internally rotate, chin on chest, bear down
38
What is the Bechetrew test
Seated SLR
39
What is slump test
Seated maximum SLR Seated SLR, foot dorsiflexed, leg internally rotated, with spine “slumped”, bearing down
40
What nerve roots and peripheral nerve is the femoral stretch test.
L2, L3, L4 | Femoral nerve
41
What are spinal loading (kemps, valsalva, flexion) results of radicular syndrome
Rapid reproduction of leg symptoms
42
If there are neuropathic findings what is the next step
- find which nerve root is involved - is it irritated, soft neurologic sign, hard sign - what is the cause
43
Once you have enough clues a nerve root is damaged, call it a radicular finding. If it has no defects, call it _______. If it has even one defect, call it _______
Radiculitis | Radiculopathy
44
what is Alcock’s syndrome
Pudendal nerve lesion *the back probably will not hurt.
45
What are three reasons of peripheral nerve entrapment and compression?
- piriformis syndrome - perineal nerve compression - femoral neuropathy secondary to pelvic tumor
46
What are three peripheral nervous system diseases
- diabetes -alcohol neuropathy Vitamin B12 deficiency
47
What is the leg pain neuropathic tool for peripheral nerve
Follow a peripheral nerve territory (stocking distribution) - often burning, may be stabbing, electrical, sharp Not likely to be affected by spine position
48
What is the leg paresthesia neuropathic tool of peripheral nerve?
Usually present and in a peripheral nerve territory (stocking distribution)
49
What is the SMR neuropathic tool of peripheral nerve
May be one or more deficits usually corresponding to the same peripheral nerve
50
What is the nerve tension test neuropathic tool of peripheral nerve?
Often reproduce leg symptoms
51
What is the spinal loading procedure of neuropathic tool of peripheral nerve
Usually do not reproduce leg symptoms
52
What nerve roots make the femoral nerve
L2-4
53
What are three causes of femoral neuropathy
- diabetic mononeuropathy - Tumor - Psoas or iliacus hematoma
54
What motor symptoms might be seen with femoral nerve damage
Hip flexors and knee extensors affected first. First sign may be knee buckling - week iliopsoas and quadratus muscle testing. Single leg raise form chair * if there is also adductor weakness, the lesion is NOT the femoral nerve but more proximal (lumbosacral plexus or L2-4)
55
Which reflex is associated with femoral nerve? Which stretch test?
Patellar reflex Femoral stretch test - creates sharp anterior thigh pain
56
T/F there is motor involvement with Meralgia Paresthetica
FALSE
57
What age tends to get Meralgia paresthetica?
40-60
58
What is one of the most common neuropathies
Peroneal nerve entrapment from crossing legs while sitting
59
What might be characteristic of perineal nerve entrapment
- foot drop may be partial or complete (often primary presentation) - weak ankle dorsiflexion, great toe extension or eversion - numbness/paresthesia over lateral aspect of lower leg and dorsum of foot Forced ankle inversion may increase pain because it stretches the nerve
60
T/F cord problems are not commonly associated with low back pain
T
61
What are three injuries that could cause cord compression? What disease?
- TLJ compression fracture - upper lumbar disc lesion - spinal canal stenosis - diabetes
62
T/F both CES and spinal cord compression symptoms include urinary incontinence, constipation and impotence
T
63
What are 5 pathologies associated with a positive Romberg’s test?

64
What is the leg pain neuropathic tool for lumbar myelopathy?
- May or may not be present - Location: Generalized, sometimes soles of feet (not dermatomal) - Quality: Often described as burning - Severity: Usually back pain is worse than leg pain
65
What is the leg paresthesia neuropathic tool of myelopathy?
May be present but not dermatomal, often a sense of numbness
66
What is the SMR neuropathic tool of myelopathy?
May have some sensory loss (contralateral pain, ipsilateral position sense/vibration/two point discrimination), may have UMNL signs, may have +Romberg/balance tests)
67
What would the nerve tension test neuropathic tool show for myelopathy
Negative
68
What would spinal loading neuropathic tool for myelopathy show
Symptoms not affected by spinal loading
69
How do you make a diagnosis of deep referred pain?
Exclude neuropathic pain. This is based primarily on negative results
70
What is the leg pain neuropathic tool of deep referred pain
Usually not past the knee (but definitely can be) Location: More general, non-dermatomal Quality: achy, crampy, grabbing (many possible descriptors) Severity: Back pain usually > than leg pain Sometimes affected by prolonged spine position
71
What is the leg paresthesia neuropathic tool of deep referred pain
Not usually present, but when present it is non dermatomal
72
What is the SMR neuropathic tool for deep referred pain show
Usually no deficits
73
What does the nerve tension tests neuropathic tool for deep referred pain show
Usually negative (may aggravate LBP)
