Is muscle thickness different in persons with cervical vertigo?

The Longus Colli thickness was higher in the patients with cervical vertigo than healthy subjects.

How do the authors interpret this research?

The authors hypothesized that the higher thickness of Longus Colli may a compensatory mechanism in the patients with cervical vertigo.  

They go on to write,

How do we interpret this research as clinicians?

It is inherently known in the rehabilitation profession that a mis-match exists between the deep and superficial deep cervical flexors and extensors in individuals with vertigo, dizziness, neck pain, whiplash, mTBI and concussion.  The mis-match can vary depending on the plethora of studies performed over the last 20 years, but generally speaking, there is a motor control disturbance placing too much of a demand on the superficial vs deep musculature.

The current study is quite interesting that prior to reading it, I would have hypothesized that the Sternocleidomastoid (SCM) would have higher thickness values.  Instead, the findings are the opposite, with the Longus Colli taking first place.

Overall, I utilize this one study as another puzzle piece for a multi-sensory condition.  This does not change my practice patterns.  I will not stop inhibiting the SCM and aim to activate the Longus Colli more effectively as this works and works well.

This research makes medicine and science interesting and progressive.  I am glad we now have the technology to perform these types of studies in rehabilitation and I look forward to future research by this group or other groups to continue to help others.

You can learn more about the screening and treatment process of Cervicogenic Dizzinesss through Integrative Clinical Concepts, where the author and his wife, a Vestibular Specialist, teach a 2-day course.  Pertinent to this blog post, the first day provides the most up-to-date evidence review from multiple disciplines to diagnose through the “Optimal Sequence Algorithm” to assist in ruling out disorders and ruling in cervical spine, including determining if single or double entity exists.
