Less than 10mm diameter of spinal canal (15-27mm normal)

26
Q

common S/S of lumbar stenosis

A

Radiculopathy (motor weakness, parathesia, impairment of sensory nerves)
Central= often bilateral symptoms
Lateral=often lateral symptoms
Ease discomfort- trunk flexion, sitting, lying
Aggravate- standing, lumber extension

27
Q

what is disco degeneration

A

Degradation within the disc of the nucleus pulposus with fissures (crack/split) in the annulus fibrosus

28
Q

what can increase disc degeneration

A

diabetes

29
Q

what is the General term for age related wear and tear of the bones, cartilage, ligaments and discs of the spine

A

spondylosis

30
Q

spondylosis is typically characterized by

A

narrowing of the disc space or arthritis of the facet joints

31
Q

main symptom of spondylosis

A

General neck pain and stiffness
Can be associated with radiculopathy

32
Q

what is spondylolisthesis

A

Spondylolisthesis- anterior translation of the vertebral body relative to the other, and secondary to an abnormality of the pars interarticularis

33
Q

what is the most frequent lumbar injury in adolescent

A

spondylolisis

34
Q

spondulolisthesis occurs most commonly where

A

l5/s1

35
Q

spondylolisthesis can affect load sharing how

A

Inc shearing forces
Higher sacral slope and pelvic tilt
Inc pressure on discs, facet joints, leading to degeneration
Muscle spasm of ES to protect

36
Q

see the table of differential diagnosis of mechanical low back pain

A
37
Q

postural muscle tend to respond how with low back pain

A

with tightness in the form of spasm or adaptive shortening
Examples: psoas, QL, Erector spinae

38
Q

phasic muscle tend to respond how with low back pain injury

A

with atrophy
Examples: Abdominals, glutes

39
Q

if you have difficulty sitting you may have

A

lumbar instability or muscle spam

40
Q

what is discogenic pain

A

flexion for extend period of time

41
Q

when performing SLR if the athlete have pain primarily in the back it would indicate what

A

Back pain primarily=most likely from disc herniation from pressure on the anterior theca of the spinal cord

42
Q

when performing SLR if the athlete have pain primarily in the leg t would indicate what

A

Pain primarily in leg=pathology causing pressure on neurological tissues more laterally

43
Q

what could indicate a positive slump test for neurmeningeal tract

A

If unable to extend knee fully, take tension off c-spine (extend it) and if knee is able to extend fully, the symptoms decrease then POSITIVE for tension in the neuromeningeal tract

44
Q

slump test is more (sensitive/specific) than SLR
SLR is slightly more (sensitive/specifi) than slump test

A

sensitive, specific

45
Q

what is the cross over sign/ well leg raise

A

If opposite leg to the affected leg is lifted and there is pain on the affected leg it is an indication of a space occupying lesion (e.g. herniated disc or inflammatory swelling)

46
Q

cross over sign indicate what and if positive what would you want to ask

A

Typically indicates a rather large disc protrusion, and usually medial to the nerve root

If positive, ask question regarding bowel and bladder control

47
Q

PKB test indicate what

A

Unilateral neurological pain in the lumbar area, buttocks or posterior thigh may indicate an L2 or L3 nerve root lesion

Test also stresses femoral nerve
Careful history and pain differentiation will help determine between tight quads or femoral nerve irritation

48
Q

finding of quadrant test and what it is

A

Patient stands with examiner behind them
Patient extends the spine
Patient then side flexes and rotates to the side of pain

Position causes maximum narrowing of vertebral foreman and stress on the facet joint in which rotation occurs

+ve- radiation, local irritation, SI joint irriation

49
Q

one leg standing (stork stance) trst

A

Patient stands on one leg and extends the spine while balancing on one leg
Repeat opposite leg

Positive test indicated by pain in back
Pars interarticularis stress fracture If fracture is unilateral, standing on ipsilateral leg causes more pain

50
Q

how long do you hold the Mckenzie slide glide test

A

10-15s

51
Q

what is pheasant test

A

Patient lies prone

With one hand the examiner applies pressure to the posterior aspect of lumbar spine

With the other hand, the examiner passively flexes the patients knees until the heels touch buttocks

If the hyperextension of the spine causes pain in the leg the test is considered positive and indicates unstable spinal segment

52
Q

what is passive lumbar extension test

A

Patient prone and relaxed
Examiner passively lifts both extremities at same time to about 1 foot from bed
While maintaining lift, gently pull on legs
Positive: pt complains of strong pain in L/S, very heavy feeling
Pain disappears with returning to start position

53
Q

H&I instability test positive

A

Positive for instability
Hypomobility
At least 2 of the movements into the same quadrant would be limited

Instability
One quadrant will be affected but by only one of the moves (i.e “H” movement or “I” movement)

54
Q

what is type 1 dysfunction of lumbar

A

SB and rotation are opposite in neutral
multi-segmental (3+ vertebra) and adaptive

Restrictions found in “Neutral” (but are correct in Flex/Ext)
NSR(L)
NSR(R)

See a rotation in TPs in neutral
Left TP is anterior, right TP is posterior—what rotation is this?

Rotation is corrected in extension and flexion

55
Q

what is type 2 dysfunction of lumbar

A

In flexion/extension with SB and rotation same
Single segmental and traumatic

56
Q

Assess the L/S in neutral (pt prone). Place thumbs on TPs of lumbar segment you are looking at (example L4)
- Note if one thumb is more anterior then the other
- Example: R thumb is more anterior than L thumb than

A

left rotation of the L4 segment and if there’s more than 2 segment it multisegment so type one dysfunction

57
Q

if 3 or more TP’s remain prominent prominent in neutral (but disappear during flexion AND extension) than a

A

neutral (type 1) dysfunction is present

58
Q

if one segment is stuck in either flexion or extension a _ is present

A

If one segment is stuck in either flexion or extension, a non-neutral (Type II) dysfunction is present- FRS or ERS

59
Q

if you palpate the lumbar spine TP and your left thumb is more posterior and right thumb is more anterior in neutral

when you sphinx, both thumb even out but when you go into child pose, the thumb return more posterior on the left and anterior to right what does it mean

A

ERS dysfunction because the vertebra love to be in extension and when you go into flexion it don’t want to so it doesn’t even ou
