Introduction Preventing disease is always preferable to treating disease.
Back pain is like tooth decay and the common cold, affects all of us, at some point in our lives. Nobody is immune to this condition or its potential disability which does not discriminate by gender, age, race or culture.
At any given time 20% of the population will be suffering from back ache 75% of population will suffer from back ache at some time in their lives .
Natural history of back ache – It gets better! – 40 to 50% of patients improve within one week. – 85 to 90% patients improve in 6-12 wks. – 75% of patients recover within 6 mo. – 90% improve with conservative treatment only.
Natural History of back ache – it usually comes back! – 40% of patients with acute back pain report recurrence at 6 mo follow-up. – 44% of patients - chronic phase by 2 yrs. – No definitive diagnosis found in 85% of LBP cases.
Medical research supports return to work programs as a best practice during the recovery phase from back ache. Return to work combined with therapy often results in faster recovery Absolute bed rest is NOT necessary for a quick recovery
Oh…My poor back! 3 types of back problems Acute Chronic Recurrent
“I bent forward to pick up……” Acute problems Usually can pinpoint a time and/or incident Usually localized in low back Pain may vary from mild to extreme Examples Muscle spasm Locked facet (joint) “Crick in my neck” “Catch in my back” Impinged facet “I drove 8 hours straight” Uh, Oh!
“I’m sorry, I can’t go _____ because of my bad back” Chronic problems Problem that lasts longer than 14 days Usually from “wear and tear” May stem from an acute problem Examples Arthritis Degenerative disc Nerve inflammation
Same story...different day Recurrent Problems Acute “flair ups” of chronic condition Made worse by certain activities Examples Sacroiliac Joint Problems (SI) Where pelvis joins the spine Can cause shooting pain
anatomy
36% of load transmission is through the anterior columns 64% is through the posterior columns 64 36
Facet Joints 24 pair = 48 joints! Allow movement of spine Made of same “stuff” as all other joints The facet joints ensure that your back doesn’t bend of twist further than it should The Links
Ligaments Ligaments help to keep the vertebrae in position Help to prevent injury by stabilizing the spine and limiting its movement. Bands of tough tissue Encase the spinal column Connect vertebrae to one another
Inter vertebral discs “ SHOCK ABSORBERS “ of spine. ANNULUS FIBROSIS NUCLEUS PULPOSIS Hygroscopic, Water content 80-90%(diurnal variation) 70-76%(adults) Always under tension - transmitted to annulus as tensile force.

Bio mechanically disc degeneration is divided into 3 stages Dys functional stage ( traumatic tears of annulus, degen. of nucleus ) Unstable stage ( disc, facet facet degeneration, ligament laxity ) Restabilisation stage ( disc collapse, fibrosis, osteophyte formation ) – “ SPONDYLOSIS”
What is a disc prolapse ?
If a disc is strained beyond its’ limit, causing the outer casing to tear, the inner substance can seep out. If this substance presses on or irritates a spinal nerve, you feel pain or tingling in the leg. The leg pain is known as “sciatica”.
LOADS ON INTERVERTEBRAL DISCS IN VARIOUS POSTURES
Lying supine-25%
Lying on side-75%
Standing -100%
Standing and bending forwards-150%
Bending forwards and lifting weights-220%
Sitting-150%
Slouching-185%
Sitting and bending forwards / lifting weights- =/>275%
COMMON CAUSES OF BACK ACHE
Common Causes of Low Back Pain Poor posture while standing e Improper lifting/bending Poor posture while standing
Poor posture while sitting Infrequent exercise Excessive weight and weak abdominal muscles may cause a spinal imbalance Common Causes of Low Back Pain
Dysfunctional sleep position
Dysfunctional sleep position Plays a role in 80% in causing - Pain … neck, shoulders, arms, hands, upper back, low back… Dysfunctional sleep positions - Stomach sleeping, Twisted / side arm(s ) overhead
Lying on your side, with knees bent, supports the natural curve of the back. Use a pillow to support the neck, especially if your shoulders are broad.
Sleeping on the stomach can increase the low back curve and stress the neck and shoulders. If you must sleep on your stomach, place a pillow under your hips to support the low back.
Sleeping on your back is restful and correct when the knees are properly supported.
BIODYNAMICS
The Forces Involved With the fulcrum in the center, it only takes ten pounds of pressure to lift a ten pound object . 10 kg 10 kg
The Forces Involved If you shift the fulcrum to one side, it takes much more force to lift the same object. Your waist acts like the fulcrum in a lever system, on a 10:1 ratio. Lifting a 10 kg object puts 100 kg of pressure on your lower back. 100 Kg 10 kg Fulcrum Lever distance Maximum load on lower back
The Forces Involved Lifting a ten pound object actually puts 1,150 pounds of pressure on the lower back!
It’s a Little Known Fact… The average human head weighs approximately 5-7 kgs. About as much as a bowling ball!
The head-neck support system can be likened to a 5-7 kg. ball on a flexible shaft stabilized by wires. The muscles pull down to stabilize , the stronger the muscles, the more force is transmitted through the spinal column
Every 2-3 cm forward the head is held requires 7 to 14 kg of extra muscle tension in the muscles of the neck
Bad Posture Predisposes to fatigue of muscles Leads to soreness and stiffness, exhaustion, stress and increased risk of injury Misalignment of bones cause abnormal wear and tear of joints

Prevention Of Back Injuries
Stacking / Retrieving Objects
Prevent Back Injuries Avoid lifting and bending whenever you can. Place objects up off the floor. Raise/lower shelves. Use carts and trollies.
Use cranes, hoists, lift tables, and other lift-assist devices whenever you can. Test the weight of an object before lifting by picking up a corner. Prevent Back Injuries Get help if it’s too heavy for you to lift it alone.
Bend with your knees not with your back. Lift with your legs. Hold the load close to your body. Contract your stomach muscles as you lift. Keep your back aligned and upright as you lift. Avoid twisting while lifting. Lifting NNMC Chiropractic NNMC Chiropractic
Lifting Straddle the load to keep it close to your center of gravity. NNMC Chiropractic
Lifting Never bend at the waist to lift. NNMC Chiropractic
When possible push your load. Do not pull heavy objects . Pushing versus Pulling NNMC Chiropractic NNMC Chiropractic
Getting In and Out of a Car Do not step into a car. Sit on the seat and then pull your legs into the car. Reverse the process for getting out.
Correct Postures
Posture - is the single most common cause of painful soft tissue syndromes affecting the body
A Better Core Equals a Better Back Your ”core” muscles—comprised of the abdominal and back muscles- act like that of a corset to hold everything in or support and stabilize your lumbar spine. The result is a slimmer shape , and more importantly, a spine that is supported against strain, pain and injury.
A Healthy Core Equals a Healthy Back
To build a functionally strong back— a better back for life you must first address posture
Dynamic Vs Static exercises Muscles are involved in two types of activity – Dynamic & Static Dynamic –muscle fibers contract and relax as a result fresh oxygenated blood flows into the muscle each time it relaxes.
Static Muscle fibers contract and remain contracted for a long time – results in a continuous deficit of oxygenated blood . Waste products accumulate produce feeling of pain, fatigue , tenderness resulting in cramps – sustained contraction of muscle which cannot relax on its own.
Sitting or standing for long periods produces static loads on the para spinal muscles
Myofascial syndrome Pain due to irritation/injury of musculo ligamentous structures Worse in mornings and evenings,relieved by walking. Frozen back syndrome
Mechanical syndrome Pain due to instability of lumbar spine motion segment. Worse in evenings and on bending relieved by lying down. Spondylolisthesis/ retrolisthesis/ vaccum disc/ facet arthropathy etc.
Inflammatory syndrome Caused by Discitis Osteoporosis Ankylosing spondylitis Reiters syndrome Rheumatoid arthritis Psoriatic arthropathy Fibromyositis etc. Mornings stiffness and pain, relieved by walking and as the day progresses.
Neural compression syndrome Caused by PIVD/ canal stenosis. Need to differentiate new symptoms from old ones.
“How successful is surgery?” We’re not perfect, but.. Greater than 85% of patients undergoing spine surgery have significant, dramatic, or complete relief of their pain arm/leg improves sooner and more completely than neck/back More than 75% patients have improvement in their function More than 90% of working patients return to work
“Wait a minute here, Mr. Crumbley ….Maybe it isn’t sciatica after all.”
Ergonomics
Ergonomics and Prevention Step # Key Word Description 1 Analyze Analyze the risks you may be exposed to on a particular job . 2 Minimize Minimize identified risks by finding ways to reduce repetitive motion and excessive force. 3 Neutralize Neutralize awkward postures that may cause strain and tension by placing your body in a natural, relaxed position. In a neutral position your shoulders and back are relaxed, your neck is straight and your arms and elbows are close to your body
Correct sitting posture
Ergonomically Correct Work Station
Chair – Low Back Support is Essential
Wrong Sitting Posture – Sitting on Front Edge of Chair
Chair Height Feet flat on floor May need a foot rest Thighs parallel to the ground Or knees slightly lower than hips
Chair Too High
Chair – Seat Pan Depth 1-2 inches from back of knees to front of seat
Seat Depth Too Long: can cut off circulation Too Short: does not provide enough support
Increasing abdominal pressure Decreases the load on the spine by 40%! One kg load in front of abdomen exerts a 5 kg load on the spine while standing. Back rest decreases stress on back.
All exercises to be done deliberately and slowly. There should not be any jerky movements. Rest in between exercises is as important as the exercises themselves. Do not over do the exercises do only 3 to 5 repetitions of each exercise. Exercise for 10 seconds rest for 20 seconds.
Low Back Exercises Avoid impact and twisting activities : Running, Tennis, Golf Exercise shouldn’t cause any pain or any dizziness. If it occurs, stop the exercise immediately.
Minimize problems of your back by exercises that tone the muscles in your Back, Abdomen, Hips and Thighs.
Exercise! Exercise regularly, every day. Warm up slowly . . . A brisk walk is a good way to warm up. Inhale deeply before each repetition of an exercise and exhale when performing each repetition.
Exercises to strengthen your back

To Conclude…..
If you work at a desk, consider stretching throughout the day to keep your muscles flexible and avoid injury.
What should one do? Move! If you stand for a long time… Sit Down once an hour for a few minutes If you sit for a long time… Stand Up once an hour for a few minutes If your belly’s big… Lose Weight ! If your legs are tight… Stretch ! … Exercise !
Believe ½ of What You See, None of What you Hear … You Need a Firm Mattress You Need a Flat Pillow All Waterbeds are Bad Always Use Heat Back Braces Make Your Back Weak You Should Always Use a Lumbar Support When Sitting Sit-ups are Good for You
Take care of your back… and it will take care of YOU! “ Remember that an ounce of prevention is worth a pound of cure.”
