Clinicians should conduct a focused
 History and physical examination to help place patients with low
back pain into 1 of 3 broad categories:
 nonspecific low back pain,
 back pain potentially associated with radiculopathy or spinal
stenosis,
 back pain potentially associated with another specific spinal
cause.
 The history should include assessment of psychosocial risk
factors, which predict risk for chronic disabling back pain
Diagnosis and Treatment of Low Back Pain: A Joint
Clinical Practice Guideline from the American College
of Physicians and the American Pain Society

Assessment of LBP
• Rule out serious pathology ‘Red Flags’
• Confirm that the pain:
• Is in the lower back - always assess the hip joint
• Is mechanical — aggravated or relieved by certain movements or
postures.
• Is not inflammatory — that is:
• Not worse in the second half of the night or after waking.
• Not associated with morning stiffness lasting more than
30 minutes.
• Not relieved by activity.
• Not associated with laboratory tests for inflammation
• Exclude specific causes of low back pain

Classification of LBP
Conventionally low back pain is categorised
according to its duration as:
 Acute (<6 weeks),
 Sub-acute (6 weeks - 12 weeks)
 Chronic (>12 weeks)
(Spitzer, W. O. and Leblanc, F. E., 1987).

Red Flags:
• Red flags for the cauda equina syndrome include:
– Saddle anaesthesia.
– Recent onset of bladder dysfunction or faecal incontinence.
– Major motor weakness.
• Red flags that suggest spinal fracture include:
– Sudden onset of severe central pain in the spine which is relieved
by lying down.
– Major trauma such as a road accident or fall from a height.
– Minor trauma, or even just strenuous lifting, in people with
osteoporosis.
– Structural deformity of the spine.

•Red flags that suggest cancer or infection
include:
–Onset in a person over 50 years, or under 20 years, of age.
–History of cancer.
–Constitutional symptoms, such as fever, chills, or unexplained
weight loss.
–Intravenous drug abuse.
–Immune suppression.
–Pain that remains when supine; aching night-time pain
disturbing sleep; and thoracic pain (which also suggests aortic
aneurysm).

Yellow Flags
Yellow flags are psychosocial barriers to recovery. They include:
• The belief that pain and activity are harmful.
• Sickness behaviours, such as extended rest.
• Social withdrawal, lack of support.
• Emotional problems such as low or negative mood, depression, anxiety, or
feeling under stress.
• Problems or dissatisfaction at work.
• Problems with claims for compensation or applications for social benefits.
• Prolonged time off work (e.g. more than 6 weeks).
• Overprotective family.
• Inappropriate expectations of treatment, such as low expectations of active
participation in treatment.

Examination:
 Observation + Tip Toe
 Palpation – muscle spasm/deformity/masses
 (Range of motion)
 Neurological tests
 Provocation tests :
 SLR & Crossed SLR
 (SLUMP)
 (Femoral Nerve ST)
 Abdomen /Hip/Lower Limb Circulation

Investigation:
• Do not offer X-ray of the lumbar spine for the
management of non-specific low back pain.
• MRI for non-specific low back pain should only be
performed within the context of a referral for an
opinion on spinal fusion.
• Consider referral for MRI if sciatica persists > 6
weeks
• ESR/CRP if suspect cancer, infection, Ank Spond
• HLA B27 if suspect AS.

Clinical Evaluation
Spring Test:
Test Positioning:
Subject is prone
Examiner stands with thumbs or hypothenar eminence
over the spinous process of a lumbar vertebrae
Action:
Apply a downward “springing” force through the
spinous process of each vertebrae to assess anterior-
posterior motion
Positive Finding:
Increases or decreases in motion at one vertebrae
compared to another (hypermobility or hypomobility)

Clinical Evaluation
 Nerve Root
Impingement:
 Narrowing of
intervertebral foramen:
 Stenosis
 Facet joint degeneration
 Herniated intervertebral
disc

Nerve Root Impingement
Tests:
Valsalva Test:
Test Position:
Sitting, examiner standing next to patient
Action:
Subject takes a deep breath and holds while bearing down
as if having a bowel movement
Positive Finding:
Increased spinal or radicular pain due to ↑ intrathecal
pressure
May be secondary to a space-occupying lesion (i.e.
herniated disc, tumor, osteophyte in lumbar canal)

Valsalva Test:
Comments:
Increase in intrathecal
pressure may result in ↓
pulse, ↓ venous return, ↑
venous pressure
(dizziness and/or
fainting)

Milgram Test:
Test Position:
Patient supine, examiner at feet of the
patient
Action:
Patient performs a bilateral straight
leg raise to the height of 2 to 6 inches
and is asked to hold the position for 30
seconds

Milgram Test:
Positive Finding:
Patient unable to hold
position, cannot lift the
leg, or has pain with test
Implications:
Intrathecal or
extrathecal pressure
causing an
intervertebral disc to
place pressure on a
lumbar nerve root

Kernig’s Test:
Test Position:
Patient supine, examiner at side of patient
Action:
Patient performs a unilateral active straight leg
raise with the knee extended until pain occurs
After pain occurs, the patient flexes the knee
Positive Finding:
Pain in the spine and possibly radiating into lower
extremity
Pain relieved when patient flexes the knee
Implications:
Nerve root impingement secondary to bulging of
the intervertebral disc or bony entrapment;
irritation of dural sheath; irritation of meninges

Patient actively flexes
the cervical spine (lifts
the head)
Hip unilaterally flexed
(no more than 900)
Knee than flexed to no
more than 900
(+) ↑ pain with neck
and hip flexion; pain
relieved when knee is
flexed
Kernig/Brudzinski Test:

Test Position:
Patient supine, examiner standing at tested
side with the distal hand around the subject’s
heel and proximal hand on subject’s distal
thigh (anterior) – maintains knee extension
Action:
Examiner slowly raises the leg until
pain/tightness noted or full ROM is obtained
Slowly lower the leg until the pain or tightness
resolves, at which point dorsiflex the ankle and
have subject flex the neck.
Unilateral Straight Leg Raise Test
(Lasegue Test):

Positive Findings:
Leg and/or low back
pain occurring with DF
and or neck flexion is
indicative of dural
involvement and/or
sciatic nerve irritation
Lack of pain
reproduction with DF
and/or neck flexion is
indicative of hamstring
tightness or SI pathology
Straight Leg Raise Test:

Test Position:
Patient standing with feet shoulder width
apart
Examiner stands behind the patient, grasping
the patient’s shoulders
Action:
Patient extends the spine as far as possible,
than sidebends and rotates to affected side
Examiner provides overpressure through the
shoulders, supporting the patient as needed
Quadrant Test:

Positive Findings:
Reproduction of patient’s symptoms
Implications:
Radicular pain indicates compression of the
intervertebral foramina that impinges on the
lumbar nerve roots
Local pain (not radiating) indicates facet joint
pathology
Symptoms isolated to the area of the PSIS
may indicate SI joint dysfunction
Quadrant Test:

Test Position:
Patient sits over edge of table; examiner is at
side of patient
Action:
(1) Patient slumps forward along
thoracolumbar spine, rounding the shoulders
while keeping cervical spine neutral
(2) Patient flexes cervical spine; Clinician
holds patient in this position
(3) Knee is actively extended
(4) Ankle is actively dorsiflexed
(5) Repeat on opposite side
Slump Test:

Positive Findings:
Sciatic pain or
reproduction of
other neurological
symptoms
Implications:
Impingement of
the dural lining,
spinal cord, or
nerve roots
Slump Test:

Hoover Test:
Test Position:
Patient supine
Examiner at feet of patient with hands cupping the
calcaneous of each leg
Action:
Patient attempts to actively straight leg raise on the
involved side
Positive Findings:
Patient does not attempt to lift the leg and examiner
does NOT sense pressure from the uninvolved leg
pressing down on the hand
Patient is not attempting to perform the test
Test for Patient Malingering:

Hoover Test:
Test Note: Examiner should be standing at feet of patient with
their hands cupping the heels of each leg

Test Position: Athlete supine
Athletic Trainer Position: At the foot of the
athlete holding a blunt tool (reflex hammer)
Procedure: Rub the tool up bottom of
athlete’s foot starting at the calcaneus and
ending at the great toe.
Positive test: Great toe extends while other
toes splay.
Implications: Lesion of upper motor
neurons, may be caused by trauma to the
brain
Comments: This reflex occurs naturally in
newborns. However, this reflex should cease
quickly after birth.

Vague signs/symptoms:
Often resemble other low back pathologies (i.e. strain/spasm
of paraspinal muscles, nerve root impingement, disc
degeneration)
Involvement:
Dislocation/sublocation of facet:
Tends to “lock” the involved spinal segment (hypomobile
vertebrae)

stands next to patient and places
both hands (one on top of the
other) directly over the subject’s
iliac crest
Action:
