Exercise, while one of The Most Important self management approaches for persistent pain, is not an easy sell to someone who is experiencing pain. Especially not if that exercise looks like huffing and puffing, hauling on bits of metal in a gym, or wearing lycra. Not to mention the “sports drinks”… Those things aside, exercising is a good thing. You heard it from me, and I have declared my body an exercise free zone! The thing is, what kind of exercise, for what purpose, and how to get introduced to it.
Personally I’m a fan of exercise that achieves something else other than “getting fit”. I like gardening, I love dancing, I enjoy cycling (especially to the store to get a GREAT coffee!). Walking the dog is fun. Swimming (especially snorkeling) is awesome! I like my exercise to do more than bring on the endorphins, especially as I don’t get much of that post-exertional analgesia that many people do – and believe me, they do (Ellinson, Stegner, Schwabacher, Koltyn & Cook, 2016). I like my exercise to look like the things I need or want to do, so that when I need to do ’em, I’m in fit state to get on and do ’em.
So what kind of exercise works best? One sage told me “the exercise the person does!” and there is some truth to that, so when I begin talking to someone about exercise, I’m looking for something they can do regularly, that fits into their lifestyle, that makes them feel good, and has some other benefit to them. That benefit might be the social thing – going to a box-fit class with a group of others all bent on getting their fix of play-fighting. It might be the solitary thing – long walks along the beach with the dog for company. It might be the music – in my case, it’s belly dance (and I dare anyone to do a 5 minute shimmy drill while keeping an isolated upper body, a loose shimmy and smile!).
I like the idea of having variety – who says we need to do the same kind of exercise every day? So it’s a wet day and I don’t fancy taking my bike out in the rain, I can turn to my dance practice, or do the dusting, or vacuum the floors. It’s a frosty day and I can go for a brisk walk and take photographs of gorgeous sparkly frosty droplets while Sheba-the-wonderdog huffs steam and sniffs at the local scents. If it’s a warm day, why not head to the pool for a lap or two? If it’s a busy day and I don’t have time, what about some “exercise snacks”? Five minutes of exercise every 25 minutes adds some pretty quickly, so it’s lunges and chair dips and wall presses and shimmy practice in between writing.
Over time we’re seeing more research looking particularly at yoga for persistent pain of all kinds. Yoga comes in many different forms, and in this case I’m guessing the more extreme forms of hot yoga and contortion is not being studied. Some of the studies are appearing in rather eminent journals, like this one from the Annals of Internal Medicine and authored by a very large team including Saper, Lemaster, Delitto and colleagues (2017).
This study is a “non-inferiority” study, looking to establish whether yoga or physiotherapy, or indeed education, can help people living with chronic low back pain. Now I’m not going to do a blow-by-blow analysis of the study, that’s for you to do. What I am going to do is look at what the yoga consisted of – and see why, perhaps, yoga is getting so much research interest. BTW, yoga was found to be non-inferior to physiotherapy, and both yoga and PT were more likely than education to have a clinically meaningful response, although neither yoga nor PT were superior to education.
This is the basic format of the yoga class: Each class began with relaxation and meditation exercises, yoga breathing, and yoga philosophy. It continued with yoga poses and
concluded with relaxation. Pose variations and aids (such as chair, strap, and blocks) accommodated various abilities. Thirty minutes of daily home practice, facilitated by a DVD, a manual, and take-home yoga supplies, was strongly encouraged.
Yoga appeals to many because it seems to begin where people are at – it’s not huffy-puffy, things don’t jiggle, and generally the classes begin and end with the ritual of breathing and meditation. I like the idea of yoga (and yes, I’ve done a class or two!), because it doesn’t involve a lot of gadgets, you can do it alone or in a group, and it feels good. What I don’t like about yoga is the need to get effective and consistent feedback about how well you’re performing the poses, especially in the beginning, which means it can be difficult to do on your own without a teacher.
For people who find exercising both difficult and painful, yoga is a good place to start. I think attending classes is crucial (or at least having an instructor and a mirror!). Learning to use the meditation and breathing is integral to the exercise – and it’s this that I think makes yoga an effective addition to the exercise toolkit. What I’m less sure of is whether it’s better than any other form of exercise – or, in my case, the many different types of movements that I use in my weekly routine. And there’s the rub. As an occupational therapist, exercise is something people choose to do as a form of occupation (valued and meaningful activity). I also enjoy a bunch of other movement-based occupations, and to me these are as valid as yoga or the PT exercises included in this study. What my approach lacks, however, is a researched basis for it.
But here’s the thing: to date the research supporting exercise for people with persistent pain shows modest effects. And those effects are completely lost if the person doesn’t do the exercise. So why not have a wide range of whole-body movement practices to draw on, allowing the person to pick and choose and get out and do something every day, even if it doesn’t fit with our modern notions of what exercise should be?
