Home › Blog › I’ve Returned and So Apparently Are the Neck Multifidus Muscles after Exercise!

I’ve been out for six weeks sailing the Med. It was another great trip and a much-needed break for an old guy! Today, let’s cover a new study that shows that cervical multifidus muscle atrophy can be recovered with exercise.

Getting Back

If you recall, we are on a four-year journey to sail the Mediterranean, Adriatic, and Aegean seas. My wife and I do that in two 6-week clips on the shoulder seasons in the late spring and early fall each year. At first, this was drinking from a fire hose as there was an incredible amount to learn, but now we’re very comfortable.

On this trip, we left Valencia and sailed along the rest of southern Spain into the south of France, Monaco, and finally, northern Italy. Above are some of my favorite pics. If you’re interested in where we went and what we did, I have an Instagram account that I only use to document our sailing voyages; see https://www.instagram.com/chriscenteno541/.

Multifidus Atrophy

The multifidus is the primary stabilizing muscle of the spine. It’s responsible for actively protecting the facet joints, discs, and nerves. The muscle can atrophy after neck or back trauma, and this can lead to active instability that can be the beginning of the degenerative cascade causing pain (4-12). While multifidus atrophy is easy to see on MRI and has been associated with headaches, neck, and back pain, regrettably, this finding is often not read by reading radiologists. So, to see if you have it, you must learn how to read your images for this finding.

Here are some videos I did that show you how to read your images for this abnormality:

• Here’s a blog on the topic of reading cervical MRIs for multifidus atrophy

I have also previously highlighted some exciting work showing that inflammatory cytokines are ramped up in these atrophied multifidus muscles (15). What’s not known is whether this is cause or effect.

Can Atrophy of the Multifidus Be Recovered with Physical Therapy?

The US healthcare system spends hundreds of billions annually treating back and neck pain. So, getting the multifidus muscle back is a multi-billion-dollar question. Is it possible?

A small 2019 study examined intensive exercise for patients with multifidus atrophy and low back pain (1). While the group of 14 patients as a whole didn’t show differences in their atrophy, the patients who did show improvements had better pain/functional results. A tiny retrospective pilot study also showed improvements with exercise in a handful of patients (2).

That’s about it; not much has been published on conservative exercise-based treatment for multifidus atrophy.

Restoring the Atrophied Cervical Multifidus with Exercise

I’ve highlighted the work of Jim Elliott, PT, Ph.D., on this blog. In this new research, five women with cervical multifidus atrophy had pre and post-MRIs and underwent ten weeks of neck strengthening. As a result, there was a mean improvement in multifidus atrophy as seen on MRI, measured by larger spinal stabilizers and less fatty infiltration in the multifidus. Those changes coincided with less pain and better physical function.

It’s important to note that while we have 100+ studies showing that multifidus atrophy is associated with headaches, neck and back pain, we have only small preliminary studies showing the effects of physical therapy on the condition. This severe discrepancy between knowing there is a problem and how best to fix it remains concerning.

There have been other approaches to helping this problematic atrophy. For example, a large case series out of the Middle East showed that injecting PRP into the atrophied multifidus also seemed to improve the MRI appearance of this fatty infiltration (16). Also, an RCT has recently been published using an implantable stimulator to help low back multifidus atrophy patients with excellent, durable pain/functional results but no tracking of MRI fatty infiltration (16).

The upshot? We are just beginning to see preliminary evidence that exercise can treat multifidus atrophy in selected patients. Hopefully, we’ll see better treatment research on this critical and ubiquitous clinical condition.
