Light Cupula - What Is It and What Should I Do About It?

Sep 27, 2022

Have you ever observed sustained (lasting > 60 sec) geotropic nystagmus with positional testing for BPPV and were not quite sure what those atypical findings were about? If so, you are not alone. According to the literature this finding is not as result of BPPV, but rather due to a light cupula which was first proposed by Hiruma in 2004.

My journey with experiencing a light cupula

Clinically, I actually do not remember ever seeing someone present with sustained geotropic nystagmus. If I did, the patient likely got better, not as a result of my treatment, but rather due to the natural history, which we will cover later in this post.

What Is The 5 Minute Cover Test?

May 07, 2022

Did you know that dizziness, headaches, and pain in the sinus region can be due to a binocular vision dysfunction (BVD)? There are several tests we can use to assess for this, but let's review one of the simplest being the 5 Minute Cover Test. Before we do this though, let's do a quick review of what a BVD is.

BPPV Treatment: 3 Reasons Why It's Not Working

Vestibular Hypofunction Treatment Guidelines - Update

Jan 04, 2022

As health care providers we like to say that we provide evidence based treatment, but what is the evidence for the vestibular therapy we provide? Specifically, how about the treatment we provide for vestibular hypofunction?

With being a busy clinician it can be a bit daunting trying to keep up with the latest research. We also have to realize that for every good piece of research there is research that is, well, not so good. So, how do we filter out the clinically relevant and strong evidence based research?

Fortunately, from time to time clinical practice guidelines come out and provide direction. Over the past few years there have been clinical practice guidelines developed for...
