What is Back Pain ?

The spine has two basic jobs:

1) to protect the spinal cord

and 2) to allow us to move.

Back pain usually involves some

loss of ability to move easily.


What is back pain4 l.jpg
What is Back Pain ?

A “pinched” nerve ?

What is Back Pain ?

A “herniated” disc ?


Slide6 l.jpg

What is Back Pain ?

Most disc herniations occur at L5-S1

At least 30% of the healthy symptomless population have clinically significant disc protrusions (Stadnik et al., 1998).


Slide7 l.jpg

What is Back Pain ?

Several studies have shown that there is no correlation between MRI findings and patients’ low back symptoms.

1. Wittenberg et al., 1998

2. Smith et al., 1998

3. Savage et al., 1997

What is Back Pain ?

There are many more joints in the back than discs.

There are many more muscles than joints.

The most common cause of low back pain is when one or more muscles “forget” to relax. We call this a somatic dysfunction.


Slide9 l.jpg

Common Sources of LBP

Somatic dysfunction

Muscle in “spasm”

Nerve root

In somatic dysfunction, some muscles become overactive (“spasm”)

and other muscles become inactive.


Slide10 l.jpg

Muscles

Joint Receptors

Joint receptors

vasculature

Muscle Spindles

Blood vessels

viscera

Nocioceptors

Pressure, temperature

chemical

Internal organs

Connective

tissues

Humoral Factors

circulating hormones

(gender-specific response)

immune proteins

cortisol

Bones and ligaments


Common sources of lbp l.jpg
Common Sources of LBP

Any dysfunction involving the thoracic or lumbar

spine, the sacroiliac joint or the hip can create

low back pain.

2. laterally - gray rami communicantes

Common Sources of LBP

Long dorsal si ligament

sacrospinous ligament

sacrotuberous ligament


Role of the sacroiliac joint l.jpg
Role of the sacroiliac joint

The coxal bones consist of a thin shell of cortical bone (1-2 mm) over trabecular bone.

Muscles play an important role in helping the pelvis resist stress.

When muscles can’t work due to pain, the risk of injury increases.



Slide17 l.jpg

Role of the sacroiliac joint

The sacroiliac joint requires muscle activity to keep it stable. If muscles can’t work correctly, perhaps because of a somatic dysfunction, the joint becomes unstable and painful.

Who gets back pain l.jpg
Who gets back pain ?

  • Almost Everybody

    • Estimates run as high as 80% of the population.

    • Frequently associated with pregnancy.

    • Peak occurrence is between age 40 and 60.

How can you stay pain free l.jpg
How Can You Stay Pain-free ?

Have good genes – studies of identical twins show a reasonably strong genetic component to disabling low back pain.

Avoid sudden unintended movements. This is the presumed cause of most cases of somatic dysfunction.

Maintain good posture. A spine that is too flat or too curved increases stress on all the joints and the discs.

Exercise regularly and moderately.

Have regular check-ups by your physical therapist, to find and fix somatic dysfunctions before they cause bigger problems.


How can you stay pain free23 l.jpg
How Can You Stay Pain-free ?

Avoid sudden unintended movements. This is the presumed cause of most cases of somatic dysfunction.

A sudden movement:

1) creates a quick stretch on muscles and joints

2) increases pressure on discs

3) increases sensory stimulus to the spinal cord


How can you stay pain free24 l.jpg
How Can You Stay Pain-free ?

Maintain good posture. A spine that is too flat or too curved increases stress on all the joints and the discs.

Lordosis

A normal lumbar lordosis helps to distribute stress evenly and absorbs shock when you walk or jump.

Sitting with a small towel roll in your low back

can help to maintain this position.

However you sit, though, you should change position at least every 20-30 minutes.


How can you stay pain free25 l.jpg
How Can You Stay Pain-free ?

Exercise regularly and moderately.

Begin slowly.

Don’t try to do too much at once.

Pick a good time.

Watch what you eat.

During the first hour after waking, the

spine is 3 times as stiff because discs have

swelled overnight (Adams et al., 1987).

You should delay exercise for an hour or

two after you wake up.

Have regular check-ups by your physical therapist, to find and fix somatic dysfunctions before they cause bigger problems.

Everyone knows it’s important to have regular check-ups at the dentist to prevent little problems from becoming big ones.

Why is your spine any different ?

Regular spine health check-ups can prevent little problems from turning into big problems later.

Treatment approaches

Slide28 l.jpg

Treatment Approaches

Adequate treatment must address all the

factors involved in producing pain.

Adequate treatment starts with a good evaluation.

A good evaluation must include an examination of

muscle function.


Slide29 l.jpg

Treatment Approaches

  • In general, treatment will involve three phases. The process is known as “rehabilitation.”

  • Phase 1

    • identify and treat somatic dysfunctions.

  • 2) Phase 2 - identify and treat specific muscle insufficiencies using

  • a) exercise

  • b) movement re- education).

  • 3) Phase3 - identify and treat specific functions needed for return to activity.


Slide30 l.jpg

Treatment Approaches

Although for many years there was no agreement among

health professionals on how to best treat back pain,

there is now some evidence to suggest that this three-pronged

approach is the most effective treatment strategy for most patients.


Slide31 l.jpg

Treatment Approachesphase 1

1. Effective non-specific techniques:

Hot packs, gentle ROM, mild exercise,

relaxation exercises, stress reduction , biofeedback,

acupuncture, healing touch, thermal ultrasound, PNF,

Craniosacral technique, thrust manipulation

2. Effective specific manual physical therapy techniques:

Muscle Energy, Strain/Counterstrain, Functional Technique,

Myofascial Release, Medical Exercise Therapy , thrust

manipulation.


Slide32 l.jpg

Treatment Approachesphase 1

All specific manual therapy techniques

(Muscle Energy, Counterstrain, Myofascial Release,

Functional techniques and specific thrust technique)

require the therapist to be well-trained in joint biomechanics.


Slide33 l.jpg

Thrust techniques

High velocity, low amplitude thrust techniques can be used

in the acute stage to correct somatic dysfunctions.

Low velocity joint mobilization techniques can also be used successfully.


Slide34 l.jpg

Treatment Approachesphase 2

Identify specific muscle insufficiencies remaining from the period of somatic dysfunction.

Hides (1998) - 39 acute LBP patients, all had decreased multifidus size at one level (mostly L5). Randomly assigned to either specific exercise group (multifidus and transversus co-contraction) or general exercise group.

Outcomes at 10 weeks identical. However, the multifidus in the general group was smaller than in specific exercise group.

One year later, 84% of people in general group had back pain again, compared to only 30% in specific group.


Slide35 l.jpg

Treatment Approachesphase 3

Identify requirements to return the patient to highest

level of function possible.

This may involve providing orthotics to support weak arches, so that walking and running won’t stress the back,

or perhaps a high level exercise program to keep

the back healthy and pain-free.


Slide36 l.jpg

Treatment ApproachesSurgery

Everyone will agree – surgery should be your last resort.

Schofferman (1992) and Blair (1994), confirmed that psychological factors play a role in success of spinal surgery. Specifically, psychological trauma suffered in childhood negatively influenced the outcome of spinal surgery, regardless of surgical complexity or other medical factors. Among the factors the researchers considered were: physical or psychological abuse by a care-giver, abandonment, and use of drugs or alcohol by care-giver.
