Work related musculoskeletal disorders (RSI) and Back Pain
With rapidly increasing industrialization in India, especially in the sectors of Information Technology and IT enabled services, work related musculoskeletal disorders (also called Repetitive Strain Injury [RSI] or Cumulative Trauma Disorder [CTD]) are spiraling upwards. Preliminary reports of one of the leading work related injury research center’s (Recoup.org, Bangalore) ongoing study of over 35000 Indian IT professionals (2001-2008) found that 75% reported musculoskeletal symptoms related to work and 55% got injured within a year of starting their first job, reducing the productivity or work efficiency to a significantly low level.
Making the Diagnosis
"Up to 85% of pts cannot be given a definitive diagnosis because of weak associations among symptoms, pathological changes, and imaging results."
Deyo R, et al. JAMA 1992; 268;760-765
Mechanical Low Back Pain "Many, including myself, believe the character of the vast majority (possibly as many as 97%) of low back disorders to be mechanical."
Donelson R. J Musculoskel Med 1991;8:14-29
Bed Rest vs Exercises
"…. continuing ordinary activities within the limits permitted by the pain leads to more
rapid recovery than either bed rest."
Malmivaara A. Hakiinen U, Aro T, et al. "The Treatment of Low Back Pain" N Engl J Med 1995;332:351-355
Williams Flexion Exercises
" Knee to chest and partial sit-up exercises may actually slow recovery"
Bigos S "Acute Care to Prevent Back Disability" Clin Ortho and Related Res 1987;221 (August):121-130
Muscle Layers
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
Deep
Multifidus, Quadratus lumborum
Iliocostalis, longissimus, (Erector s.)
Superficial
Thoracolumbar fascia
Lattisimus dorsi
Lumbar ligaments
ALL, PLL
Ligamentum flavum
Facet capsules
Interspinous ligaments
Supraspinous ligaments
Pain Generators
Annulus Fibrosis (outer 1/3 only?)
Periosteum
Neural Membranes (Anterior Dura)
Ligaments/ Z-joint capsules
Muscles.
Imaging or Not?
Low yield without RED FLAGS present.
"Abnormal" findings in Asymptomatic.
Jarvik- LAIDback study.
Psychological.
Anxiety, fear-avoidance- possibly help?
Depression- "there must be something wrong"
Guidelines for Imaging
NO RED FLAGS!
Acute pain- symptomatic treatment for 4 weeks, re-evaluate. Image if pain continues.
AHCPR Guidelines for Acute LBP.
Sub acute pain- Pain for >4wks.
Failed symptomatic treatment. Image.
Chronic pain- none, unless changes in sx’s
Chronic intermittent- TX as acute patients
Who needs Surgery? Or who only needs Surgery
Unstable Spine
Acute fractures with Neurologic deficit.
Severe Stenosis
After failure of aggressive non-operative tx.
Tumor?
Progressive Neurologic deficit
Recently several large studies of surgical approaches such as diskectomy, fusion, and IDET have not demonstrated efficacy – even for patients with established radiculopathy and HNP
1997 1st RCT to find that Lumbar Stabilization Exercises could treat and prevent future episodes of Low Back Pain and Disability in Patients with Spondylolithesis:
O’Sullivan et al: Spine 1997
Active System - Muscles
Many layered and overlapping muscles both anterior and posterior
Core Muscles:
n Transversus Abdominis (TrAb) anteriorly
n Multifidus posteriorly
The "deep subsystem"
n External Oblique
n Internal Oblique
n Rectus Abdominis
The "superficial subsystem"
Transversus Abdominis
Flexes, forms a rigid cylinder, assists in respiration, and decreases shear and torque forces
Note the fiber alignment, which allows you to see "Nature’s Back Belt"
Multifidus
Trunk extensor
Postural control (segmental control)
In same fascial plane as TrAbd
Why is it important???
Interesting Back Fact: Active System
Initial onset of LBP or subsequent acute episodes create a one-sided, one level atrophy of the multifidus muscle, which does NOT spontaneously recover when pain goes away.
Currently being investigated as a possible reason for the high recurrence rate of LBP
No chronic back pain treatment should be without motor control / coordination exercise
Neural Control System
Earlier studies focused on retraining "mechanical stability" of the spine through muscular training – mixed results
Recent research focuses more on the neural control aspect
Bottom line- it’s about endurance and control not strength, and "spinal stability" is a nervous system construct, not a muscular construct
In those with LBP, the contraction of the TrAb is delayed, demonstrating poor motor control.
We need to retrain this feed-forward, or anticipatory, contraction to help patients control their LBP and maintain stability
Why Not Surgery?
Re-operation Rates over 4 years:
Decompression 17-18%
Spinal Fusion 21-28%
N=24,882!
This isn’t the percentage who failed to be helped – it’s the percentage that failed to be helped AND needed another procedure.
ICD codes indicating fusion failure, hardware failure, or pseudoarthrosis
Make the DIAGNOSIS!
Remember finding is not a diagnosis..!
Spinal degenerative changes can be noted in normal individuals too
A positive MRI shouldn’t be the diagnosis! It’s just a finding……
Asymptomatic Adults- MRI Abnormalities
Disc degeneration 46- 72%
Bulging Disc 24- 81%
Disc Herniation 22- 40%
Annular tear 14- 56%
Stenosis 1- 21%
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
All types of Back pain is having Muscular-myofascial components Caused / Continued by cumulative traumas
The usual Mechanical Components for Chronic - Recurring Back Pain are chronic muscular spasms, which may be 1º & 2ndary (strains-sprains). 1º (muscle - motor unit - fatigue), 2ndary (nerve entrapment)
Ongoing Back Pain Symptoms are 95% Musculo – Myofascial (is it called idiopathic?).
In origin symptoms are not equal to cause…!
Make the Diagnosis, determine the specific anatomical muscular-myofascial dysfunction(s) then identify the causes for the anatomical musculo-myofascial dysfunction(s) which can be classified as Primary & Secondary, or in another way as Precipitant Cause (s) and/or All Contributing Cause (s)s
Back Pain: Etiology
Highest estimate: <10% Spinal canal: Intervertebral path: Disc ruptures, Radicular,
< (<1%) operable disc
Highest estimate: <5% Structural: stenosis, fracture, unstable. < ( <½ %) operable
Lowest estimate: >85% Idiopathic: (musculo,ligamentous, myofascial, facet, etc.)
Chronic Musculo-skeletal Strain-sprains Brought-on &/or Maintained by Cumulative Traumas developed during Daily Living – Work - - Recreation
Back pain symptoms May be relieved by:
a. Increasing central tolerance;
b. Central blocking of thalamic reception;
c. Interference with spinal neural receptors;
d. Severance of neural pathways;
e. Silencing the site or origin; or
f. Removal of the causes.
Back pain symptoms may be removed by Elimination of the causes
If back pain is an elephant our present understanding method is like
"The Blind Men and the Elephant"
Back Pain- Causation
The precipitant: may be a specific event.
Cause of pain is rarely singular usually multiple
All Back Pains are Cumulative-Trauma Phenomenon

Managements
How will you manage a case of back pain?
From where you will start?
Single technique or a comprehensive approach?
Who will be the apt person for a back pain management?
How can you provide complete cure without relapses?
How will you manage a case of back pain?
Forgot the older concepts of individual approaches. Just think about the patient as a whole…………
From where you will start?
All back events are Osteomyofascial, you have to start from the reverse. That means to start from the fascia then muscle and then the Osteal part, but remember that the integration should consider the patient as a whole.
Single technique or a comprehensive approach?
Of course the approach should be always comprehensive, incorporating the above three….
Who will be the apt person for a back pain management?
The answer is a Physical Therapist…., of course he should have very deep knowledge in Back pain, mechanics, complete evaluation ( do you know one thing, a normal back pain evaluation will take a minimum of 30 minutes!), through hands on experience which is up-to-date. A Physical therapist is the only person who can implement the holistic approach. Before staring the treatment a case discussion with your Orthopaedician / Neurologist / PMR will be healthy and it will produce a positive feedback to them too.
How can you provide complete cure without relapses?
It needs an intelligent evaluation, planning & implementation. In SCeB CAPT® we are using AJIMSHAW’s Approach® for managing various Osteomyofascial dysfunctions including Back Pain.
AJIMSHAW’s approach is a unique program designed by Dr. Ajimshaw.
