Q

What are the stages of the SLR test?

A
  1. supine, passively flex straight leg at hip until px reports pain or tightness in post leg; now lower leg until symptoms are no longer present (but no further)
  2. px foot is then passively dorsiflexed; this also places a stretch along the nerve via the tibial nerve
  3. if stage 2 is negative, ask px to actively flex neck (while maintaining step 2)

Q

What does a positive SLR test implicate? What are we primarily looking for? What’s another possible implication?

A

Test usually points to a posterolateral disc herniation due to the dural tension pulling the nerve towards the space-occupying lesion (or herniation) lateral to the nerve(s). The later 2 stages of the test (DF and forward C flexion) may also be positive for meningeal irritation if the patient reports pain or restrictions in the neck or back. Remember to always ask where the patient is having the pain! If px can’t flex neck at all, they may be suffering from meningitis.

39
Q

What are the implications of the Bowstring test?

A

If the SLR is positive or if irritation and inflammation of the sciatic nerve is suspected, the sciatic nerve may be directly palpated in the popliteal fossa of the knee. Pressure (or strumming) on the nerve will cause symptoms to be felt locally and distal to the part of the nerve being palpated.

40
Q

What’s the aka for the Femoral Nerve Stretch?

A

Nachlas test

41
Q

What’s the purpose of the Femoral Nerve Stretch/Nachlas test?

A

Neural tension test used to stress femoral nerve and mid lumbar (L2-L4) nerve roots

42
Q

How is the Femoral Nerve Stretch/Nachlas test applied?

A

Px is prone; therapist passively extends the hip (15°) with the knee extended. If no reproduction of S/S is present the therapist then slowly passively flexes the px’s heel to the buttocks.

43
Q

What’s a positive sign for the Femoral Nerve Stretch/Nachlas test?

A

reproduction of pain or paresthesia over the L2 and/or L3 and/or L4 dermatome area (lower back and anterior thigh region) may indicate a lesion or irritation to the femoral nerve

44
Q

What is the implication of the Femoral Nerve/Nachlas test?

A

This test puts the femoral nerve on stretch, and unilateral pain may be positive for L2 or L3 or L4 dermatomes (mostly L2 and L3) if there is no lesion or contracture to the quadriceps muscle. The feeling or paresthesia is known as formication.

45
Q

What’s the purpose of the Valsalva test?

A

tests for herniated disc, osteophyte, or any other space-occupying lesion

46
Q

How is the Valsalva test performed?

A

Ask a high-seated px to take a breath, hold it (at least 6 seconds), and then bear down as if evacuating the bowels. Or have them blow into their thumb.

47
Q

What’s a positive sign for the Valsalva test?

A

reproduction of symptoms either locally in the spine or down the leg

48
Q

What’s the purpose of Milgram’s test?

A

tests for intrathecal (herniated disc) or extrathecal (soft tissue injury) pathology

49
Q

How is Milgram’s test performed?

A

px is supine; have them raise both extended legs about 2 inches off the table and hold for 30 seconds

50
Q

What’s a positive sign for Milgram’s test?

A

Positive is pain and/or an inability to raise or hold the legs off the table. This test may be a little overly optimistic as many people have trouble holding their ankles off the table.

51
Q

What’s the purpose of Hoover’s test?

A

test is designed to see if the client is malingering or exaggerating their complaint of low back pain

52
Q

How is Hoover’s test conducted?

A

supine: take each of px’s heels in palm of my hand; ask px to raise each leg individually; when px raises one leg, I should feel downward pressure from other leg

53
Q

What’s a positive sign for Hoover’s test?

A

no downward pressure from contralateral leg when px lifts ips leg (means px is not actually trying to lift ips leg)

54
Q

What’s the aka for Kemp’s test?

A

quadrant test

55
Q

What’s the purpose of Kemp’s/Quadrant test?

A

tests for possible facet joint irritation, or foramenal stenosis

56
Q

How is Kemp’s/Quadrant test performed?

A

px is standing; have them rotate and extend their trunk while running their hand down the back of their thigh

57
Q

What’s a positive for Kemp’s/Quadrant test?

A

localized pain on ipsilateral side

58
Q

What are the implications of Kemp’s/Quadrant test?

A

The movement provides greater provocation by decreasing the Intravertebral foramen of the lumbar spine on the side to which the client bends. This test puts ultimate pressure on the facet joints by placing them in their close-packed position. Facet joint pain may be site-specific to the facet that is provoked, or may radiate several centimetres around the joint. Localized pain on the same side may also come from: an injured muscle being placed in a short position and then spasming, pressure placed on inflamed iliolumbar ligaments or from compression of the joint surfaces of the sacroiliac joint. The latter can mimic neurological pain in the gluteal-hip region. Pain from the side not being tested usually comes from tissue being stretched.

59
Q

What is the purpose of the Pheasant test?

A

tests for spinal instability (L-spine)

60
Q

How is the Pheasant test applied?

A

Px is prone; place one hand on the patient’s lumbar spine and gently compress. With other hand, pick up px’s ankles and passively flex knee until ankle is at buttocks.

61
Q

What is the positive sign for Pheasant test?

A

Hyper-lordotic presentation in the L-spine and/or pain in lower limb. (some versions of this test suggest an Achilles Tendon Reflex test at beginning and end of this test)

62
Q

What’s the purpose of the Segmental Instability test?

A

tests for spinal instability (L-spine)

63
Q

How is the Segmental Instability test applied?

A

Patient is prone on the table with their legs hanging off (hip passively flexed at 90°); the therapist will apply P-A glides segmentally over individual SPs of the lumbar spine while the px remains relaxed. Once pain is identified over a particular segment, the therapist maintains pressure then instructs the px to lift their legs up off the floor by contracting the hip and spinal extensors.

64
Q

What’s a positive sign for the Segmental Instability test?

A

Positive sign will result in LBP with pressure when the px is relaxed, and no pain when pressure is applied with active muscle contraction (i.e. when legs are extended). This lack of pain is attributed to the area of instability being protected (and masked) by the muscular contraction.

65
Q

How is the QL muscle test applied?

A

(Impossible to test in isolation, the following can give an indication as to strength or weakness)

Px is prone with one thigh/leg slightly extended and abducted. The degree of abduction is intended to mimic the line of pull of the muscle’s fibres. Px attempts to elevate pelvis (hip hike). Therapist opposes with a longitudinal traction of thigh/leg along line of pull of the muscles’s fibres.

66
Q

How is the Latissiumus Dorsi muscle test applied?

A

(More of a shoulder muscle, but does have some influence on tilting the pelvis anteriorly and laterally. Weakness may result in diminished lateral trunk flexion.)

Prone: px attempts to adduct the arm in a position of extension and medial rotation. Therapist applies pressure against the forearm in the direction of abduction and slight G/H flexion.

67
Q

How is the Lower Abdominals muscle test applied?

A

(Refers to the lower fibres of all 4 abdominal muscles. Note: it is impossible to separately test the individual abs, but it is clinically important to isolate the lower and upper fibres of the ab group.)

Supine: hips flexed to 90° and knees fully extended. The px should tilt their pelvis posteriorly to flatten the lumbar spine against the table. Therapist can place their hand under px’s lumbar spine to gauge when they lose the ability to maintain a posterior pelvic tilt. Px slowly lowers their legs to the table. Instruct them to continue pressing low back into your hand.

The strength of the lower abs is graded on their ability to maintain a posterior pelvic tilt during the leg lowering.

68
