BPPV is the most common cause of dizziness across the lifespan. Fortunately it is usually straight forward to treat. At times it can, however, be a bit tricky, especially if it involves the lateral canal. According to 2017 Clinical Practice Guideline for BPPV 5-15% of the time the lateral canal is involved. When the lateral canal is involved there are several treatment options. One of the newer ones being the Zuma maneuver.
Over the years I have become pretty comfortable treating lateral canal BPPV. I like using the BBQ Roll if canalithiasis is involved. If cupulolithiasis is involved I like using the Head Shake Maneuver. I will then follow it up with the BBQ Roll, if needed.

It is well known that concussions are common. They can, however, be a challenge to treat, both for the patient/athlete and care provider. Given such, there have been attempts to prevent concussion through education awareness, rule changes in sport, and equipment (i.e. helmet) modification.
With that in mind have you heard of the Q-collar? There are claims that is has the ability to reduce the risk and severity of a concussion?
A few years ago I started seeing football players in the CFL and NFL wearing something around their neck. It looked like a skinny set of ear muffs. When I looked into it I found out that the device was supposed to prevent concussions, or at least the severity of...
Have you ever wondered about the relationship between drugs and oculomotor testing? From time to time I was curious, but never looked into it until I received an email a few months ago from Ocular Data Systems asking if I could work with them on a project to provide online lessons regarding vestibular physiology and how to analyze nystagmus findings for law enforcement officers, prosecutors, and toxicologists.
It seemed like a unique opportunity, a Canadian physical therapist helping educate law enforcement officers, prosecutors, and toxicologist from the USA. What I did not realize until then is that there is a group of very highly trained non-medical professionals who perform oculomotor...
I am not sure any of you watched the NFL game with the Bills and the Dolphins on Sunday September 25, 2022? If you did you would have seen the Dolphin’s QB Tagovailoa get pushed backwards, causing him to fall and hit his head on the turf. He was able to get up on his own. However, as he jogged across the field his legs looked like the scene of Bambi on the ice. If you missed it, here is a REPLAY.
With that, if you are like me, you were thinking that he was definitely going to be out for the rest of the football game. Then, the shocker came when he was allowed to resume play.
Did he sustain a concussion?
Recognizing and evaluating...
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.
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.
This past summer though, I released an online course...
If you are like us, you taken many vestibular therapy courses without being taught how to treat BPPV affecting the anterior canal. Granted, BPPV affecting the anterior canal is rare. If you, however, see a lot of patients with dizziness you will likely see this form of BPPV at some time. When that does occur what are your options?
Given such, let's review a treatment option that we have found simple and effective called the Deep Head Hang Maneuver. Before we review the technique let's review some background information.
If you follow the media, especially in regards to celebrities you may have heard that Canadian singer Justin Bieber was recently diagnosed with Ramsay Hunt and will have seen that his smile seems a bit off. He is not the only celebrity to develop a facial paralysis. Angelina Jolie, George Clooney, and Pierce Brosnan all developed facial paralysis, but they had Bell’s Palsy which is different than Ramsay Hunt and we will compare the two conditions below.
So, what exactly is Ramsay Hunt? Well, Ramsay Hunt or herpes zoster oticus is a neurological condition caused by a virus that affects the nerves on one side of the head. If someone has this condition, the two main findings...
Have you ever heard of anyone getting BPPV from binge watching Netflix? We recently did.
Usually our blogs are more on the technical side. We, however, thought that we would change it up a bit with this post and use a case study format, especially given the interesting onset.
First of all we will figure out if binge watching Netflix can cause BPPV. Secondly, we will go over the actual case study.
The simple answer is, kind of.
With BPPV, really two things need to occur.
BPPV occurs when these two factors coincide.
Some of the otoconia in the inner ear that help detect head position and motion need to...
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.
Binocular vision dysfunction is a condition where the eyes are not looking in the same direction. When looking straight ahead, to the side, up, down, as well as near and far the eyes should be aligned and move together as a pair. Causes of BVD are usually due to poor functioning of a nerve or nerves that control eye movement, or of the...
Are you a health care provider who enjoys the challenge of assessing and treating individuals with dizziness?
Would you like to help more patients who are dealing with dizziness?
Or, are you simply looking for a niche market?
If this is you, good call as there is so much need to provide vestibular therapy services.
Over the years we have been intentional in marketing our services which has been key in seeing well over 100 new vestibular referrals a month. At North 49 we actually see more people with dizziness than we do with all MSK conditions combined and hope to share what we have learned with you so you can have the same success in less...
