Just breathe…

One of the things I keep getting asked about and that also appears to be getting more popular within physiotherapy is the use of breathing techniques and respiratory training for musculoskeletal conditions. Not having considered this much in my day to day practice I thought I would take a look at the role of breathing training for musculoskeletal problems and see if it is something we should be focusing on.

Now breathing techniques and respiratory training are key interventions for our colleagues who work with patients with cardio-respiratory conditions, but we should we also be using these techniques for patients with musculoskeletal conditions such as back, shoulder, hip, or knee pains?

Personally, as an MSK physio breathing is something I don’t consider at all for the patients I see, usually there are far more important things to focus on. Now that’s not to say breathing is not important, in fact, breathing is an essential activity and I highly recommend everyone does it. But for me the best type of breathing is the type you do without thinking about it, usually inhaling followed by exhaling and repeating as often as needed.

However, I do recognise that pain, anxiety, fear, and physical exertion can adversely affect breathing, often increasing its rate, reducing its tidal volume, even causing it to stop at times, and I do see some of my patients do these things in response to some of the tasks or exercises I ask them to do. So I do occasionally get a patient who I can see is tense, guarded, and holding their breath to take a few deep breaths before they do something they anticipate will hurt. I also get some patients who I can see are breathing too fast or too shallow due to fear or anxiety to also take a few deep slow breaths to help calm them and their breathing rate down.

So I guess I do focus on breathing a little more than I first thought, but this isn’t intentional and certainly doesn’t use any fancy techniques, and it isn’t something I ask patients to focus on as part of their treatment. But there are some who advocate that MSK therapists should focus on breathing more with their back, hip, knee or any other pain to help patients function better, and I kind of understand this thinking.

There is evidence that those with back pain have different positions and fatigability of their diaphragms than those without pain. However, these changes could be because of pain rather than contributing to it. Also these things could be pre-existing before pain started and related to other factors such as low physical activity levels. However, there is some evidence that focusing on breathing can improve reported pain levels in both acute and chronic low back pain and so it may be a good idea to get patients to do this.

However, before you all go and get your patients to behave like hyperventilating puffer fish, or start watching their abdominal rise and fall it’s important to consider if it’s worth the time and effort of using breathing techniques. Some research shows that the pain modulating effects from respiratory training are quite small and actually unlikely due to the respiratory training and so the question remains why bother?

Personally, I think the breathing issues I see in my patients are due to the anticipation of, or as a consequence of fear, anxiety, or pain. Therefore, I prefer to prioritise my treatments that address these things, not to focus on the consequences. If I do give some breathing training then I just tend to do nothing more than asking them to take a few deep slow breaths.

However, there are some such as the bonkers Postural Restoration Institute who advocate that we should go a lot further into breathing re-training and get our patients to focus on their diaphragms, chest expansions, and inspiratory muscle strength, even blowing up balloons with their arms and legs in the air and doing some weird and wacky shit. Or the bat shit crazy Naudi Aguilar from Functional Patterns who thinks you need to wrap elastic bands aound your ribs. This profession never ceases to amaze me with some of the daft and stupid things it thinks is both useful or effective for pain or disability.

Simply put this kind of crap is nothing more than a waste of time, energy, and money. I’m sure many of the advocates of these techniques will tell you of all the patients they have helped, but the reasons why these stupid interventions work are not by the explanations given, instead it’s due a host of other non-specific effects that I have discussed before here.

But, as daft as the physio profession can be with its breathing re-training interventions, these pale into insignificance when it comes to the crazy world of strength and conditioning at times. Here we enter into a whole new level of stupid about how breathing training can improve strength, endurance, and performance.

The daftest gimmicks are these inspiratory masks and valves that are thought to replicate high altitude oxygen deprived environments and so create increased physiological responses to training. These masks replicate high altitude training just as much as sticking your feet out of a car window replicates running fast, or flushing your head down the toilet simulates swimming. To simulate a low oxygen environment, you need… wait for it… a low oxygen environment, these masks simply don’t filter oxygen from the atmosphere.

What these masks actually do is reduce the airflow into your lungs so increasing the effort to breathe, this is whats called inspiratory muscle training. This is a bit like trying to breathe through a straw or a pillow that is being smothered over your face. Now our cardio-respiratory colleagues will tell us that this is an effective intervention for those with respiratory conditions or disease, that is inspiratory muscle training by the way, not pillow smothering!

However, for helping to improve athletic performance there is little evidence that inspiratory muscle training and these masks do anything except make you look like a twat. There are some studies that show the effects of inspiratory muscle training improve respiratory function in athletes, but little evidence that this translates into improvements in their performance.

Don’t get me wrong using some simple breathing techniques when training can be useful. For example, breathing in deeply and then holding the breath at the bottom of a heavy squat or deadlift can help brace the abdomen and trunk via the Valsalva manoeuvre, and breathing out forcefully during the effort phase of the lift can help generate power.

In summary, there is no doubt that breathing is essential and most of you should definitely keep doing it, and there is no doubt that breathing can be abnormal in the presence of disease, pain, fear, and anxiety. But there is little evidence to say that these breathing issues are causative of these things. Many therapists are focusing on breathing training in musculoskeletal conditions such as back pain when there is also little evidence that these interventions are effective, and for me breathing interventions are low on the list of things to focus on with the people I see. However, if I do then it usually is nothing more than asking a patient to take a few slow deep breaths with no balloons or stupid masks in sight.

As always, thanks for reading.

  1. Hey Adam, as a second year physio student I really enjoy reading your articles and I hope to employ your challenge everything philosophy in my own practice when the time comes. I suffer from asthma, and have since I was a child. After watching several power/endurance tests at Uni, I theorized about how much WOB really contributes to fatigue in an athlete, let alone a respiratory challenged individual. I decided to employ a “training mask” in my daily cardio etc. I realize that the hypoxic simulation is B/s, but I believed if I could in attempt to train my respiratory system in a progressive overload fashion, maybe that improvement in efficiency when unloaded would translate to improved efficient respiration. I wont lie, it was very hard going initially, but after 12 months of employing it 2-3 days a week on the lowest (3000ft) setting, I had my second respiratory test in a lab at Uni. Sure enough the customary asthmatic dips between FEF25-50 had noticeably improved, but remained lower in the FEF75. I rarely use it now but I run over 30km a week, and have no out of breath moments at all.

    • Hi Ben, thanks for the comment and kind words. Inspiratory muscle training is an effective method for respiratory issues like asthma and glad it worked well for you… however for pain… its kind of meh!!! Cheers and keep running… Adam

  2. As always Adam, you have entertained me with your turn of phrase, and your honesty, I have used breathing with some people who are anxious and in pain, more to help calm them as you said you do, it’s not the focus just an adjunct to get them through and feel safe, cheers Sharon.
