I’ve been blown away by the overwhelming amount of interest in Dr. Loren Fishman’s Side Plank Research, originally published in 2014 in the Wall Street Journal. I’ve written three separate blog posts on the subject (here’s the first, second and third), and they’re by far the most read and commented posts on Spiral Spine’s site. I’ve also corresponded with others privately on social media and email, each of whom were asking for guidance as to which side they should perform the plank on.

As you may already know from my previous posts, I disagree with Dr. Fishman’s findings and have been quite vocal about it.

Recently, Dr. Fishman has published an article on Huffington Post that has stirred the pot even further and reintroduced the Side Plank Research to the public at large. While I agree that specialized exercise is crucial for those with scoli, a one-size-fits-all exercise approach for scoliosis doesn’t exist. There is no “magic pill.”

But let’s investigate this further.

I’ve been in contact with a mom whose 15 year-old son who has scoli. This mother is determined to avoid surgery for her son, and in doing so, has taken him to Spinal Dynamics to learn the Schroth Method as part of a weeklong intensive program. And although the Schroth exercises were showing a slight reduction in his curves, her son was getting bored from, “staring at a wall for 30 minutes a day doing his exercises.”

She then came across the aforementioned Side Plank Research but was confused as to which side her son should perform the plank on (along with the rest of the scoliosis world), so she set up (and paid for) multiple Skype sessions with Dr. Fishman to confirm that her son was indeed doing the plank correctly.

They followed Dr. Fishman’s instructions precisely and the young man did his side plank for 3-4 months (even though he was supposed to do it for a full 6 months per Dr. Fishman) but he stopped because his shoulder was hurting from doing the exercise.

Unfortunately, here are the son’s results, measured and confirmed by X-rays:

–Before the side plank exercises, his high thoracic curve measured 34 degrees; his lower curve measured 47 degrees.

–After performing the side plank exercises for 3-4 months, his high thoracic curve increased to 50 degrees; his lower curve increased to 60 degrees!

These young man’s curves got significantly worse after doing the side plank exercise exactly as prescribed by the doctor who created the side plank study. This further proves that Dr. Fishman’s research is fundamentally flawed and in fact, can make your scoliosis worse.

Well, now what?

After decades of study and training in scoliosis management, here’s what I know to be true:

  • Exercise works to reduce scoliotic curves.[1] [2] [3]
  • You have to determine which specific exercises will help reduce your individual curves.
  • A qualified movement practitioner can help you determine which exercises are good for your body. Need help finding a practitioner? Watch these videos from the Spiral Spine Starting Point series. Videos 4 and 5 tell you what to look for when searching for a practitioner in your area. Also watch the Spiral Spine TV video titled, How Do I Make My Scoliosis Better?  for additional guidance.
  • Once you’ve found a movement practitioner and discovered which exercises help decrease your specific curves, do these exercises regularly and track your progress with a scoliometer.

Having scoliosis is confusing enough; don’t be fooled by perceived quick fixes. Take control of your health and find out what works for you.

I’m going to leave you on a positive note and share an email I received from a mother whose daughter has scoli in Alabama:


Just want to share some good news with you. Sabrina (her daughter) had X-rays yesterday and they show that she’s down to 25 degrees from 32 degrees back in October. All the therapy works. I remember back in the Orthopedic Dr.’s office in October 2015, they promised me that Sabrina would only get worse no matter what I tried. They told me that only a back brace could stop the progression and even then, there was only an 80% chance that it would work. Look at her X-ray today. It’s amazing!!!! We are so excited. Thanks for your help in our journey.


To clarify, I’ve never met this mother or daughter in person. I haven’t talked to either of them on the phone or Skype. I’ve never taught her daughter a lesson. None of this is about me, the work I do work with my clients, or what I do for my own scoliotic body. It’s about the fact that these modes of therapy work – and they can work for you (minus the side plank).

      Hi Sarah,
      I’ve seen all of his research. Again, he lumps in two different kinds of scoli into the same research and I’m just not a fan of that. That being said, I occasionally do teach the half-moon pose from this research against a wall for certain clients. I usually give it as homework. Again, it depends on the client’s body I’m working on though. Needless to say, there is TONS of other movement research for scoli that’s great and effective. I’m finishing up a book right now compiling all this research (stay tuned in the next few months…). On Fusion Pilates EDU’s website I have a two hour video called Analyzing Scoliosis where I go over tons of exercises you can use. I have five more videos coming out on their site over the next two years. Again, stay tuned. I also have Hard Core Scoli and Untwisting Scoli: Maya that show Pilates exercises that are beneficial for scoli (based in other research). You can get them on amazon. I hope this helps. Blessings, Erin Myers

    Dear Erin Meyers,

    I came across your repost of this article which mentions a 15-year-old patient who got worse. I must say I certainly do have a few failures, and people in that age group have immature spines, and often would have gotten even worse if they didn’t have this message, but I can’t find a patient in my database. I have a number 15-year-olds and 14-year-olds, but actually all of them seem to have improved. Possibly This patient and/or his mother just never sent me the second x-ray because they were so disappointed, I don’t know. In general though I think you and your readership should know that we have seen 325 patients in the past three years, adults with degenerative scoliosis and younger people with adolescent idiopathic scoliosis, and two with a rather uncommon condition: osteogenesis imperfecta.

    More than 80% of those that are sent us there follow-up x-rays have improved, many dramatically. Of course there are some that have not sent us the follow up x-rays and maybe that accounts for the patient you cite in your unfavorable review of my work. What we ask patients to do takes less than three minutes today, and is innocuous, effective and almost free.

    The message you use maybe effective also, I do not know. However I’m sure that unless someone gets x-rays before they treat and sometime after they treat, there is no real way to know.

      Dr Loren,

      Thank you for the update. I’m sure all of my readers will be pleased to read your comments.

    Hello Erin
    Could you please tell me how the scoliometer app has been calibrated and what were the results?
    Thank you

    1. Erin Myers 2 years ago

      Hi Bryony, I do not know the exact metrics or system that the app was calibrated with off-hand. I do know the app was calibrated correctly and is accurate though as that was the number 1 thing I was looking for when researching someone to make my app. Are you having issues using it? -Erin

      1. Bryony 2 years ago

        Hello Erin
        Thanks so much for answering. I’m not having issues yet – I haven’t yet purchased the app. I was interested in how accurate the app tool is against measurements taken conventionally. I’ve not had my scoliosis measured before but was hoping to get an accurate reading. Thanks for the reassurance – I’ll try it.
        Thanks again.

    Interesting dialogue. I’d like to point out that just because something does not seem to make sense, that doesn’t necessarily make it untrue. The only way to truly know something is to collect data. What is striking here is that despite a disagreement on whether the exercise was done on the “correct” side, each one of the compliant patients in the original study showed improvement. That is actual data . I appreciate that you have findings on a single patient that contradicts the conclusions from the original study, however, I would respectfully suggest that a single case study by itself is not particularly meaningful. Given the medical importance, what is needed here is a more comprehensive study. This is important not only to scrutinize the findings of the original study (particularly because medical research often cannot be reproduced) but also to explore this issue further. For example, what would be result if patients performed the exercise with the concave side down? Would patients show improvement if the exercise was performed bilaterally? Last, I would suggest that the studies be powered appropriately (i.e. contain enough patients to ensure that conclusions are statistically relevant). Thank you for your scrutiny. I hope you can continue to help push the field forward.

    1. Erin Myers 2 years ago

      Hi Anthony, thanks for the reply. I absolutely agree that we need more research and correct data in the scoli world. You wrote “each one of the compliant patients in the original study showed improvement”, and that is actually not true. That’s one of my main issues with the study. If I remember correctly, there was at least one person whose scoli actually got worse in the study. Have a look at the original data. There was one massive improvement by a person in the study and when the researcher averaged the results out, that one improvement pretty much negated the scoli that got worse and the scoli that just stayed the same. That being said, because there isn’t more *good* research we must rely upon personal testimony when it comes to the side plank. I’ve had many high up Schroth PT’s from around the world privately email me saying they usually perform the side plank with the concave side down and don’t like the research (and some say they don’t do it at all and that side planks are really just a core exercise). If you know of anyone wanting to do research for scoli and exercise I’d love to be apart of it! Blessings, Erin

    Great clarification for the novice on the need for an individualized approach. An important component I am finding is the need for follow up regularly to ensure compliance and correct performance.

    1. Erin Myers 3 years ago

      I would absolutely agree. If you have a trusted practitioner who knows how to use a scoliometer in your town that you see regularly, the regular follow-up is built in. Scoli can change on a weekly, or monthly, or yearly basis depending on the season of life you are in. For that reason, you MUST have a local practitioner who you see regularly. Thanks for pointing that out Ashley.
