Low Back Pain – What works and what doesn’t, according to the research.

Be-curious-550x344

Previously I wrote about the first in a series of published papers in the Lancet regarding the global burden of disability caused by low back pain and why we need to pay attention. You can read it here.

The second paper, “Prevention and treatment of low back pain: evidence, challenges and promising directions” contains a lot of information so today I’ll begin with prevention and treatment while the next blog post will further explore current guidelines vs. what’s actually utilized in the global medical community.

My hope is perhaps you’ll come to see for yourself there are promising directions for those disabled and suffering from low back pain.

I. Prevention

Most of the widely promoted interventions to prevent low back pain do NOT have a firm evidence base.

A surprising statement, isn’t it? These include what you have likely been told over and over again to do, yet evidence of their success is not there. Strategies about workplace education, no-lift policies, ergonomic furniture, mattresses, back belts, lifting devices. How often have you heard about most or many of these in terms of how we might prevent low back pain?

What then, seems to work?

II. Treatments

First, is the recommended use of a biopsychosocial model.

I suggest most of the general public has never heard of this term or model of care. I surely didn’t just a couple years ago when I was first started to dig into the overarching problem of chronic or persistent pain that affects so many people.

What is this? Well, as often defined it encompasses “a dynamic interaction among and within the biological, psychological, and social factors unique to each individual.”  My emphasis on the ‘unique to each individual’, as that’s turning out to be an important piece of the complexity of pain.

Second, greater emphasis is needed on

  • Self-management
  • Physical and psychological therapies
  • Some forms of complementary medicine,

Along with less emphasis on

  • Pharmacological and surgical treatments.

What’s actually being utilized in our clinics?

Surprisingly, the treatments with less emphasis and effectiveness = pharmacological and surgical treatments.

Countries such as Denmark, the USA, and the UK do have guidelines around this. They are supposed to utilize exercise and a range of other nonpharmacological therapies such as massage, acupuncture, spinal manipulation, Tai Chi, and yoga.

Clinicians are meant to provide people with

  1. Advice and education about the nature of their pain;
  2. Reassurance that they do NOT have a serious disease and their symptoms will improve over time;
  3. Encouragement to stay active and continue with usual activities.

Self-Management

I understand even the notion of engaging in movement and exercise is difficult for people who are experiencing pain. How do you keep active when you are in pain? How much does advice, education, reassurance really help? People typically go to their health care providers and want something to ‘fix’ the problem. Not more advice. However, evidence shows this does help. And, evidence shows that the pharmaceuticals and surgeries we’ve come to rely on, don’t. In the long-term, particularly. If they worked, we wouldn’t find ourselves in this predicament.  Understanding that you have a part to play, in getting better, is critical. 

Movement or Exercise Therapy

Going back to the problem of trying to move, when you’re in pain. Something that people may or may not be familiar with is the term graded exposure. Basically, it means you start where you can, and gradually, over time, work to increase your overall capacity.

I tell my clients it will help to do even the smallest of movements. Use your imagination and even just visualize movement if you must, but you CAN start somewhere. Move your feet, or hands, or arms an inch, if that’s what you can do today. Just begin.

It has been shown to be useful if you can tie in your exercise or movement with something you want or need to do, rather than just some kind of exercise that is not motivational for you.

It’s not really so much WHAT you do, but that you DO something.

“Since evidence showing that one form of exercise is better than another is NOT available, guidelines recommend programmes that take individual needs, references, and capabilities into account in deciding about the type of exercise.

I use tools that yoga offers and work to help keep clients joints moving in all the many ranges of motion they might need in their life. This does not mean they need to have a life-long love or commitment to yoga.

Yet, yoga does offer an important first step of building awareness and subsequently using gentle movement, breath awareness, and tools to ‘ease into a movement’ that may have be feared in the past. People can learn to calm their nervous system, work in a safe pain-free range of motion (or not increase pain). From there we work to build stability strength and power in whatever it is they want to do … be that swimming, walking, biking, skiing, playing with kids, sitting at a desk all day. Whatever it is they want to do in their life.

Passive Therapies

It should be noted that some guidelines DO NOT recommend passive therapies, such as manipulation or mobilization (think chiropractor, massage, acupuncture). Some guidelines consider these short-term options, optional. The same goes for other passive treatments received in a physical therapists office like ultrasound, nerve stimulation, etc.

Though these passive types of therapy may help to temporarily feel better, they often have many returning again and again, becoming dependent on them for relief. Much of the current research shows the need to get a person ‘involved’ in the treatment. Get their brain and nervous system participating in movements or other practices, so passively ‘being worked on’ might not be a long-term solution.

Psychological Therapy

Guidelines also recommend Cognitive Behavioral Therapy (CBT), progressive relaxation and mindfulness-based stress reduction (MBSR).

This again is where yoga can play a part in terms of relaxation. I’ll often incorporate strategies from MBSR when working with clients.

Pharmacological Treatment

Guidelines now recommend pharmacological treatment ONLY following an inadequate response to (the above mentioned) first line non-pharmacological interventions.

Paracetamol was once the recommended first-line medicine for low back pain; however evidence of absence of effectiveness in acute low back pain and potential for harm has led to recommendations against its use.

Health professionals are guided to consider oral non-steroidal anti-inflammatory drugs (NSAIDS), taking into account risks …  and if using, to prescribe the lowest effective dose for the shortest possible time.

Routine use of opioids is NOT recommended, since benefits are small and substantial risks exists…

The role of gabaergic drugs, such as pregabaline, is now being reconsidered after a 2017 trial showed it to be ineffective for radicular pain … guidelines generally suggest consideration of muscle relaxants for short-term use, although further research is recommended.

Surgery

The role of interventional therapies and surgery is LIMITED and recommendations in clinical guidelines vary.

Recent guidelines DO NOT recommend spinal epidural injections or facet joint injections for low back pain… they DO NOT seem to provide long-term benefits or reduce the long-term risk of surgery and have been associated with serious adverse events.

Benefits of spinal fusion surgery … are similar to those of intensive multidisciplinary rehabilitation and only modestly greater than non-surgical management.

UK guidelines recommend that patients are not offered disc replacement or spinal fusion surgery for low back pain.

For spinal stenosis … patients tend to improve with or without surgery and therefore non-surgical management is an appropriate option for patients who wish to defer or avoid surgery.

So why the GAP between evidence and practice?

Stay tuned and we’ll look to see how this is played out and why it’s imperative that we change it.
