Infrared Goggles: A Comparative Guide for Vestibular Therapists

May 09, 2024

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....

Acoustic Neuroma Review

Mar 28, 2024

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.

End Point Nystagmus Differentiation

Feb 04, 2024

Do you ever struggle distinguishing between different types of nystagmus, such as end point nystagmus (EPN) and gaze evoked nystagmus (GEN)? If so, you're not alone. Working closely with therapists in vestibular therapy over the years we've found this to be a common issue. Given such, let's review three practical tips when assessing patients that we have found helpful.

Actually, before we get too far, we need to remember that end point nystagmus is a normal physiological response, while a true positive gaze evoked nystagmus finding is indicative of a central or peripheral vestibular disorder.

As we will see in this blog, end point nystagmus is a bit of a misnomer as it can be...

Dizziness Handicap Inventory & Activity Specific Balance Confidence Scale: Functional Outcome Measures Explained

Dec 29, 2023

If you're among those healthcare providers who have yet to dive into the world of Functional Outcome Measures (FOMs) when working with vestibular patients or would like to see what other healthcare providers are using, we got you covered.

In this blog we will delve into two trusted measures that have stood the test of time—ones that we've consistently relied on at North 49 being the Dizziness Handicap Inventory (DHI) and the Activity Specific Balance Confidence Scale (ABC). Over the years these measures have offered insight into how disabling patients perceive their vestibular condition to be, aiding us in designing more targeted and effective treatment plans.

Blue Light Blocking Glasses for Concussion & Vestibular Migraine: Shedding Light on the Evidence

Dec 09, 2023

As a physiotherapist, the decision to use a particular treatment often rests on a delicate balance between using something as there is strong research behind it or not. This holds true with the use of blue light blocking glasses to treat concussion and vestibular migraine. Some optometrists we have talked to indicated that they do not endorse the use of these glasses due to a lack of research. Then, on the other hand we hear from people who say these glasses were "game changers" for managing their symptoms. Is there something behind these glasses, are they a placebo, or a bit of both?

Let's explore the rationale for considering the use of blue light blocking glasses.

What is Alice in Wonderland Syndrome (AIWS)?

Nov 11, 2023

Have you ever wondered why Lewis Carroll's "Alice in Wonderland" seems like such a trippy and surreal journey? Well, there's a fascinating theory that connects this whimsical tale to a peculiar phenomenon known as "Alice in Wonderland Syndrome" or AIWS. This syndrome is closely associated with migraines and can offer a curious glimpse into the world of distorted perceptions. It has been said that Lewis Carroll himself had migraines, so this may be a tale expressing what he was experiencing personally.

Vitamin D, the Sunshine Vitamin & Its Impact on BPPV Risk

Oct 05, 2023

As healthcare providers, our primary goal is to enhance the health and well-being of our patients. One intriguing area of research that has gained attention in recent years is the connection between vitamin D and the risk of Benign Paroxysmal Positional Vertigo (BPPV). BPPV is the most common cause of vertigo, and understanding the role of vitamin D in its development can be crucial in both prevention and treatment. In this blog, we will explore the potential link between these two and discuss how healthcare providers can address this connection in their patient care.

Often referred to as the "sunshine vitamin," it plays a vital role in maintaining our overall...

What Is Autoimmune Inner Ear Disease?

Sep 09, 2023

The intricate complexity of the human body's immune system is a remarkable defence mechanism that protects us from harmful invaders. However, in certain cases, this defence mechanism can go awry, leading to a range of autoimmune disorders. One such disorder that remains relatively lesser-known but can have profound effects on an individual's life is Autoimmune Inner Ear Disease (AIED). In this blog we will shed some light on what AIED is, its causes, symptoms, diagnosis, and available treatment options.

Exercises Worth Repeating with Concussions & Vestibular Migraines

Aug 10, 2023

Wondering what treatment or exercises to prescribe to your patient with ongoing symptoms after a concussion or associated with vestibular migraines?

With seeing patients with these two conditions over the years you have likely found that they both have something in common. They can both have a component of symptoms that originate from the neck, whether it be headaches and/or dizziness. It is therefore vital to be able to address the neck in order to stop the cycle of ongoing symptoms or at least help them manage their symptoms better. At North 49, a tool that has been useful in determining if the neck is a factor in one’s symptoms and can also guide our treatment is the use of...

How To Treat Anterior Canal BPPV

May 12, 2023

With going to vestibular therapy courses have you found that learning how to treat BPPV affecting the anterior canal is often overlooked. This is understandable to some extent given that other vestibular conditions are more prevalent. Specifically with BPPV, according to Bhattacharyya, it only affects the anterior canal up to 3% of the time. Not nearly as common as the other two canals, where much of the training focuses on.

With that being said, BPPV affecting the anterior canal is rare, but it does happen. So, if you are treating patients with dizziness it is just a matter of time until you may see this form of BPPV. When you do it will be good to have a treatment technique up your...
