Introduction

Treating the lumbar spine can be a complex scenario. It is difficult to know when to apply all the techniques you have been taught and how to adapt your plan if the outcome is not as predicted. Be as specific as possible and make sure positive tests are reproducible and watch how they change over time.

Identifying recovery limiting factors and frame everything with a correct view of pain

Treatment-Based Classification System for Lower Back Pain

According to the research by Alrwaily et al, there are three simple approaches when treating lower back pain: A Symptom Modulation Approach, a Movement Control Approach and a Functional Optimization Approach. These approaches are very interesting as they address different signs and symptoms commonly found on assessment.

1. Symptom Modulation Approach

A symptom modulation approach is commonly used with patients with lower back pain. The pain can be a new or recurrent episode. The key aspect to this approach is the symptoms are the largest focus for the patient and the treatment. Patients often present with postural adaptations and fear to move or pain with movement which results in a decreased range of motion. Neurological testing is commonly positive. The most common treatments associated with this approach are manual therapy, directional preference exercises, traction, or immobilization.

2. Movement Control Approach

A movement control approach is commonly used with patients who fall into the bracket of low-to-moderate levels of pain. They also have difficulty performing activities of daily living. The patients don't appear to be very irritable or inflamed as their pain usually returns to the baseline once the aggravating movement has ended. Patients often will complain of repeated episodes of back pain, often associated with a sudden movement. A patient usually has full active range of motion, often with deviations in their movement patterns. Patients often present with impaired flexibility, muscle activation, and motor control. The most common treatments associated with this approach are stabilisation exercises.

3. Functional Optimization Approach

A functional optimization intervention is commonly used with patients who are relatively asymptomatic and have no difficulties when performing their activities of daily living but have a desire to increase their level of physical activity. This is commonly associated with a sport or job. The pain is aggravated by movement system fatigue. Patients often will complain of poor flexibility and they commonly present with a decreased endurance, strength, and power. that do not meet their physical demands.36 These patients need interventions that maximize their physical performance for higher levels of physical activities. The most common treatments associated with this approach are optimization of performance within the specific context of physical activity.

Treatment

Research shows that thrust manipulation targeting both stiff segments and painful segments is helpful for low back pain. Physiotherapists anecdotally apply this concept to non-thrust manipulation since most manual therapy techniques have similar mechanisms. The video below on the lumbar accessory mobility testing, details the examination of stiff and painful segments. These should be treated with the same techniques. Following treatment, the “asterisk signs” from the assessment should be retested to see if they have improved. An asterisk signs can be the stiffness or painfulness of the segment feels with a technique either to the patient or to the therapist.

Treatment

When it comes to treatment, remember to be as specific as possible and make sure positive tests are reproducible and watch how they change over time. Always identify recovery limiting factors and frame everything with a correct view of pain. According to Chatzitheodorou et al, patients with chronic low back pain should be encouraged to perform aerobic exercise for greater than 30 minutes 3 times each week. There are many approaches that you can take with your patient, all can have favourable outcomes, some to look into are, the Maitland approach, Mechanical Diagnosis and Therapy (or commonly known as the McKenzie approach), Cognitive Functional Therapy (Peter O’Sullivan), and Movement Impairment Syndromes (Sahrmann).

Lumbar traction is a common intervention performed.

Suggested treatment options:

• IASTM
• Lumbar Traction
• Manipulation of the Lumbar Spine

• Flexibility
• Maitlands' Mobilisation
• Mulligan Manual Therapy
• McKenzie Method
• Movement Control Tests For Lumbar Spine
• Endurance Exercises

Lumbar Traction Literature:

   • Summary from Nick Rainey: People with chronic low back pain and imaging findings of a disc issue have minimal benefit from a lot of traction when used as a sole intervention. They did not capture how the subjects felt the day of traction.
2. National Institute for Health and Care Excellence (Great Britain). 2018 Surveillance (exceptional Review) of Low Back Pain and Sciatica in Over 16s: Assessment and Management (NICE Guideline NG59). National Institute for Health and Care Excellence; 2018.
   • Summary from Nick Rainey: If you’re going to hang your hat on the NICE guidelines you can’t pick and choose. No one thing works so there are a lot of “do not offers”. Some of the things they recommend to offer I question. I put a few of the common things we encounter that I thought would be of interest below. This is for you to consider if you would recommend these options, and if you would, where would you send the patient.
     • Manual therapies
     • Exercise
     • Psychological therapy
     • Return-to-work programmes
     • Radiofrequency denervation
     • Epidurals
     • Surgery and prognostic factors

   • Summary from Nick Rainey: The exercise group looks like good treatment. There wasn’t an psychosocial info in either group. The flexion distraction technique was more helpful at 1 month, 3 months, 6 months, and 12 months and people were generally more satisfied with it. The flexion-distraction group didn’t do any prescribed exercise. Pain improved whereas other measures did not.

   • Summary from Nick Rainey: Mechanical traction isn’t magical or extremely powerful. If it were then the results would have been stronger. Both groups received the same extension oriented treatment that fit a standard Mechanical Diagnosis and Therapy model that included lateral shift correction if needed. The traction group did have 13% go on to surgery compared to 20% in the Extension-Oriented Treatment Approach group. This is despite the fact that more people in the traction group viewed surgery initially as favourable. A similar finding occurred with crossover. Four people crossed over from Extension-Oriented Treatment Approach to the traction group compared to only 1 the other way even though more people in the Extension-Oriented Treatment Approach viewed traction favourably than in the traction group.

   • Summary from Nick Rainey: There is at least some specific effect for decreasing herniated disc material.

   • Summary from Nick Rainey: This study really doesn’t tell us anything. People who are worse don’t do as well as people who aren’t as bad. The predicting factors found (non-involvement of manual work, low level fear-avoidance beliefs, no neurological deficit and age above 30 years) are positive predictor factors except maybe age above 30, but most of the participants hovered around this age.

Summary

Regardless of your assessment of the person’s problem with back pain communicating it effectively is essential. If the patient has an emergency red flag then helping them understand the gravity of it is essential so they can take the proper emergency steps. However, people, even with specific low back pain do not have an emergency and most people have “non-specific” low back pain. In the article “Easy to Harm Hard to Heal” we read many statements that patients have made in regards to their beliefs about their back. We know from Ben Darlow’s earlier work in 2013, "The enduring impact of what clinicians say to people with low back pain”, that what we as clinicians say plays a huge role in what patients believe about back pain. Focus your attention starting at the section “Vulnerability of the back” on page 2 through “The prognosis of back pain” which ends on page 8. When you read, think about two things. First, how do I make sure I never make someone more fearful than they need to be? Second, how do I help correct these beliefs if my patient has them?

You’ll still have times when you’re unsure of what’s best. Here’s a summary:

1. Work to help them not worry about what is occurring.
2. Address lifestyle issues- sleep, nutrition are big ones
3. Try manual therapy
4. Repeated motions help a lot of people
5. Low back and core specific exercises
6. Lower extremity strength exercises such as lunges and dead lifts
7. Aerobic training
