(clinical evidence 2008)
Non-specific neck pain
•
Varies with different activity – rest may aggravate OR rest may
relieve pain
•
Radiates on non-segmental distribution
•
May be sensory symptoms without signs
•
Varies with time
•
Related to
•
OR
poor posture
•
OR
overuse
•
OR
non of these
awkward movement
Examination of non-sp neck pain
•
Positional asymmetry – a change in the most
comfortable resting position
•
Unequal restriction in range of movement
(although this is common in degenerative
disease)
•
Tenderness in hypertonic muscles
•
Poorly localised tenderness
•
Localised areas of inc muscle tone? – nodules or
tender bands

Back Pain
Prevalence
 LBP affects 1/3 of UK population each year
 Only 20% of people with LBP consult GP
 MAINLY: non-specific and serious causes rare
Prognosis
 Difficult to prognosticate because of irregular course
of symptoms
 Risk factors for slower return to work:
 leg pain as well as back pain
 Repeated episodes
 Co-morbidities
 Manual work or lower socioeconomic class
 Longer duration off work
 Psychosocial factors
Definitions
 Non-specific low back pain
 Specific low back pain
 Mechanical back pain
 Inflammatory back pain
Non-Specific Low Back Pain
 pain, tension, soreness, or stiffness in the lower
back which cannot be attributed to a specific
cause.
 Sprains and strains included.
 best thought of as a symptom or complaint —
not as a disease or homogeneous condition.
 Non-specific low back pain is also called simple,
or uncomplicated, low back pain.
Inflammatory low back pain
 low back pain and stiffness aggravated by rest
or sleep
 often waking the person in the second half of
the night.
 It lasts >30 minutes after getting up
 relieved by physical activity & NSAID.
 typical of ankylosing spondylitis and other
rheumatic conditions.
Mechanical LBP
 varies with posture or movement.
 E.G.: aggravated by standing and relieved by
sitting or lying; in others: vice versa.
 Mechanical low back pain is typical of non-
specific low back pain, and specific causes such
as sciatica, vertebral fracture, and facet joint
injury.
 Importance is exclusion of inflammatory back
pain.

Diagnosis
 Rule out serious pathology
Cauda
Equina
Red flags for cauda equina
 Saddle anaesthesia or paraesthesia
 Recent onset bladder dysfunction
 Recent onset faecal incontinence
 Perianal sensory loss
 Unexpected laxity anal sphincter
 Severe OR progressive neuro deficit
Red flags for fracture
 From medical history:
 Sudden onset of severe central pain relieved by
lying down.
 Major trauma e.g. RTA, fall from a height. Minor
trauma, or even just strenuous lifting, in people
with osteoporosis.
 From physical examination:
 Structural deformity of the spine (such as a step
from one vertebra to an adjacent vertebra)
Red flags for cancer or infection
 older than 50 years, or younger than 20 years
 History of cancer.
 Recent bacterial infection (for example urinary
tract infection).
 Intravenous drug misuse.
 Immune suppression.
Red flags for cancer or infection
 Constitutional symptoms, such as fever, chills, or
unexplained weight loss.
 Pain that remains when lying down,
 aching night-time pain that disturbs sleep,
 thoracic pain (which could also be caused by
an aortic aneurysm).
 O/E: Structural deformity of the spine (such as
scoliosis).
Ruled out serious pathology…
Check pain
 From back
 Is mechanical
 Is not inflammatory (?ESR, CRP)
Check for long term prognosis

Misunderstanding of the cause of back pain.

The belief that pain and activity are harmful.

Sickness behaviours, such as extended rest.

Overprotective family.

Social withdrawal, lack of support.

Emotional problems such as low or negative mood, depression, anxiety,
or feeling under stress.

Problems with claims for compensation or applications for social
benefits.

Inappropriate expectations of treatment, such as low expectations of
active participation in treatment.
Management
 positive attitude
 realistic expectations.
 Avoid ‘threatening’ language
 'the normal ageing process of the spine' rather
than 'wear and tear', 'crumbling discs', or
'damage to disc or joint'.
Information:
 real physical cause
 disturbance of function, not by serious structural
damage.
 Settles in most people but can recur repeatedly
 Analgesia, mobilise and back to work ASAP
 normal activities should be paced
 The aim is to do a little more each day.
Information
 Care with lifting and twisting
 Cushion between knees when sleeping on side
 No need for complete resolution before work
 Work can help with distraction
 Analgesia (paracet/NSAID/opioid)
 ?use of diazepam x 5/7
 Expect resolution <6 weeks
Chronic (>6 weeks)
 Structured exercise programme
 Manual therapy
 Acupuncture
Poor response?
 Check for red flags
 Check for yellow flags
 Consider other conditions
 Consider referral to pain mgt clinic
 If severe, consider specialist spinal surgical
service -> ?fusion
Not recommended for chronic
low back pain
 Non-specific
 Less than a year
 Should not be treated or referred with:
Not recommended for chronic low
back pain
 Alexander technique (exercise likely to be more
cost-effective) not available on NHS
 Massage
 Percutaneous electrical nerve stimulation (PENS)
 Transcutaneous electrical nerve stimulation
(TENS)
 SSRI
 Injection of substances into the back
Not recommended for chronic low
back pain
 Laser therapy
 Interferential therapy
 Therapeutic ultrasound
 Lumbar supports
 Traction
 Radiofrequency electrothermal therapy
 Percutaneous intradiscal radiofrequency
thermocoagulation (PIRFT)
 Neuroreflexive therapy
Opioids in Back pain
 On the increase
 Some estimates 30% of LBP last >1y
 Cochrane review
Use of opioids
 4 studies
 3 compared tramadol to placebo
 900 patients in total…
 There still remains little evidence in the
medical literature to address the
concerns of physicians and patients
regarding the effect of opioids on pain
intensity, improved function and risk of
drug abuse.
