When I first began treating benign paroxysmal positional vertigo (BPPV), I was advised to: “Always keep a hold on the patient after sitting them up.” It was a warning about the potential for dizziness caused by otolith movement (postural crisis after BPPV treatment) or, more often, due to blood pressure changes during the final step of the maneuver.

Over the years, I’ve followed that advice religiously, wrapping both of my arms around the patient’s neck and shoulders, holding them briefly while making small talk and checking how they are doing.

That is, until one time I didn’t.

I had just completed a modified Epley maneuver with a patient. He looked stable, so I stepped back. But about 15...

At North 49, I’ve been incredibly fortunate to learn from many brilliant clinicians throughout my career and I see it as part of my responsibility to share what I’ve learned along the way. My goal is that these blogs are a means of reviewing what I have learned and assist in supporting your journey by offering practical, evidence-based insights.

This blog, however, is a little different.

It’s a summary of a doctoral project by someone I’ve had the honour of working with for several years: Nycole Pataki. Nycole recently relocated from Saskatchewan to Arizona with her family and asked if I’d read her doctoral project. After doing so, I knew this work deserved a broader audience. With her per...

Vestibular neuritis is one of the more common causes of acute vertigo seen in emergency rooms and vestibular therapy clinics alike. It is estimated to account for 3.2 to 9% of all vertigo cases seen in specialized dizziness clinics [1], and has an incidence of approximately 3.5 per 100,000 people per year [2]. While many therapists understand its classic clinical presentation of sudden onset of vertigo/dizziness lasting days, often with nausea, imbalance, and spontaneous nystagmus the underlying pathophysiology deserves a closer look.

The Classic Presentation of Vestibular Neuritis

Vestibular neuritis (most commonly due to a viral infection) typically results in an acute unilateral vestibu...

In this blog, I want to share something that over the past couple of years has repeatedly come across my path being Vestibular Paroxysmia. I first remembering hearing about it from Dr. Shepard on the Talk Dizzy to Me podcast, then glanced through it on the Bárány Society website, and more recently it came up during the Advanced Vestibular Physical Therapy cohort I was fortunate to be in through the University of Pittsburgh

I’ve come to realize that, although this condition is not common, it’s certainly out there and as clinicians who work with people dealing with dizziness, we need to keep this one in the back of our minds. My approach is: if I see something once, I park it in the back of m...

Gaze stabilization exercises, such as X1 and X2 exercises, are essential in vestibular rehabilitation for patients with unilateral vestibular hypofunction (UVH). Standard progressions typically involve increasing the duration, transitioning from a plain to a busy background, adding balance challenges, and advancing to X2 exercises. However, beyond these standard progressions, there are additional strategies that can further enhance a patient's recovery.

In this post, we will review three additional progression options that have proven useful in clinical practice.

How to Perform:

In an effort to better understand the Storage Velocity Mechanism (SVM) and its clinical significance—something that isn’t talked about much in courses—I decided to dive deeper into what it is, why it matters, and what I should know as a vestibular therapist. Here’s what I found.

What is the Storage Velocity Mechanism?

As we know, the semicircular canals detect angular acceleration. However, with motion at a steady speed the cupula in the semicircular canal returns to its resting position within 7 seconds. Despite this, we can maintain visual stability during sustained rotations, thanks to the Storage Velocity Mechanism (SVM).

The SVM essentially integrates and "stores" velocity informa...

As healthcare providers, we occasionally encounter patients with dizziness that does not fit the usual patterns of vestibular disorders. One such condition is Third Window Syndrome (TWS), which most commonly presents as Superior Semicircular Canal Dehiscence (SSCD). There are other presentations of TWS aside from SSCD and TWS itself was first described by Minor in 1998. 

In this blog, we will cover what TWS is, its causes, symptoms, triggers, diagnosis, and treatment options.

What is Third Window Syndrome?

Third Window Syndrome (TWS) encompasses a group of inner ear disorders characterized by an abnormal opening or thinning in the bony structures of the inner ear. The most well-known form...

We’re excited to share an assessment technique that has significantly enhanced our ability to evaluate patients with vestibular hypofunction: the Skull Vibration Induced Nystagmus Test (SVINT). After hearing about it a few times over the past few years, we decided to investigate further and are glad we did. Given our access to infrared goggles, implementing SVINT was quite affordable since portable handheld massage devices can be picked up at places like Walmart.

Clinically, the test has helped us pick up vestibular hypofunctions when our other battery of tests such as looking for gaze evoked nystagmus, head impulse test, head shaking nystagmus test, and dynamic visual acuity tests were unr...

At North 49, the three common questions we get asked about infrared goggles are:

1. Can we get a discount rate on goggles through North 49?
2. Do I really need goggles?
3. Which goggles do you recommend?

Can we get a discount rate on goggles through North 49?

The answer to the first question is, unfortunately no. That being said, we would really appreciate that if you end up buying a pair of goggles from Vestibular First that you use: https://vestibularfirst.com/?referredby=507 as it allows us to collect points that we redeem to purchase anatomical models that we give out as draws at our weekend courses. From time to time we also have give-away draws for our monthly newsletter subscribers. 

As a healthcare provider, seeing patients with various medical conditions is part and parcel of our daily routine. However, there are certain conditions that are relatively rare, but require keen attention and understanding for effective management should they occur. One such condition is an acoustic neuroma, also known as vestibular schwannoma. In this blog, I will provide insights into what an acoustic neuroma is, its prevalence, clinical presentation, conservative treatment principles, and indications for surgery. Then, if you want to take a deeper dive, I'll provide some of my favourite resources at the end of the this blog.
