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.

Treatment-Based Classification System for Lower Back Pain

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

Examples of these two approaches are outlined below:

1. Example of hierarchical exercise progression for patients matched to symptom modulation approach
   • Is the patient irritable or inflamed?
     • Yes, address inflammation by active rest
   • Does the patient peripheralise with extension and flexion, or have positive crossed SLR test?
     • Yes, prescribe traction
     • Lumbar Traction
   • Does the patient peripheralise with extension and flexion?
     • Yes, prescribe specific exercises that centralise the symptoms
2. Example of hierarchical exercise progression for patients matched to movement control approach
   • Does the patient stop to centralize and have no symptoms distal to the knee?
     • Yes, prescribe manipulation
     • Manipulation of the Lumbar Spine
   • Is there a sensitised neurological structure?
     • Yes, address the sensitised neurological structure
     • Neural
   • Is there a joint mobility or muscle flexibility impairment?
     • Yes, prescribe flexibility exercises or joint mobilisation
     • Flexibility
     • Maitlands' Mobilisation
     • Mulligan Manual Therapy
     • McKenzie Method
   • Is there a motor control impairment?
     • Yes, prescribe motor control exercises
     • Movement Control Tests For Lumbar Spine
   • Is there a muscle endurance impairment?
     • Yes, prescribe
     • Endurance Exercises.

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 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.

Lumbar accessory mobility testing

Signs and symptoms approach  and asterisk sign details.

Be as specific as possible and make sure positive tests are reproducible and watch how they change over time.

Treatment

Back to classification. All schools of thought are trying to be as specific as possible- Maitland approach, Mechanical Diagnosis and Therapy (McKenzie), CFT (O’Sullivan), Movement Impairment Syndromes (Sahrmann)

Lumbar traction is a common intervention performed.

Lumbar Traction Literature:

1. Schimmel JJ, De Kleuver M, Horsting PP, Spruit M, Jacobs WC, Van Limbeek J. No effect of traction in patients with low back pain: a single centre, single blind, randomized controlled trial of Intervertebral Differential Dynamics Therapy®. European spine journal. 2009 Dec;18:1843-50.
   • Summary: 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: 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 (RFA) to offer I question. I put a few of the common things we encounter that I thought would be of interest below.
3. Gudavalli MR, Cambron JA, McGregor M, Jedlicka J, Keenum M, Ghanayem AJ, Patwardhan AG. A randomized clinical trial and subgroup analysis to compare flexion–distraction with active exercise for chronic low back pain. European Spine Journal. 2006 Jul;15:1070-82.
   • Summary: 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.
4. Thackeray A, Fritz JM, Childs JD, Brennan GP. The effectiveness of mechanical traction among subgroups of patients with low back pain and leg pain: a randomized trial. journal of orthopaedic & sports physical therapy. 2016 Mar;46(3):144-54.
   • Summary: 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 MDT model that included lateral shift correction if needed. The traction group did have 13% go on to surgery compared to 20% in the EOTA group. This is despite the fact that more people in the traction group viewed surgery initially as favorable. A similar finding occurred with crossover. Four people crossed over from EOTA to the traction group compared to only 1 the other way even though more people in the EOTA viewed traction favorably than in the traction group.

   • Summary: There is at least some specific effect for decreasing herniated disc material.
6. Cai C, Pua YH, Lim KC. A clinical prediction rule for classifying patients with low back pain who demonstrate short-term improvement with mechanical lumbar traction. European spine journal. 2009 Apr;18:554-61.
   • Summary: 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.

Patients with chronic low back pain should perform intense aerobic exercise for greater than 30 minutes 3 times each week. Chatzitheodorou 2007

Chatzitheodorou, Dimitris, et al. "A pilot study of the effects of high-intensity aerobic exercise versus passive interventions on pain, disability, psychological strain, and serum cortisol concentrations in people with chronic low back pain." Physical therapy 87.3 (2007): 304-312.

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

I don’t have much in writing for this section. I don’t have much about treatment skills or the evidence for treatment. I don’t want to try to teach how to do a lumbar thrust manipulation or dry needle with a little video. There’s millions of exercises. I could teach bird dogs and extension with a video. If there’s something Plus already has for this I’m open.

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?
