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...

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.

The Importance of Vitamin D

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...

Ewald's Laws for BPPV & Nystagmus

Apr 11, 2023

Ever heard of Ewald's Laws?

If not, with assessing BPPV do you ever wonder why:

  • With BPPV affecting the posterior canal, going into the Dix-Hallpike Test is more provocative than sitting up after?
  • With BPPV affecting the lateral canal, going into the Supine Roll Test the side that is more provocative is not always the affected side?
  • With cupulolithiasis affecting the lateral canal, the nystagmus beats towards the affected ear with the Lean Test?

Maybe you have not, but understanding the WHY behind these will help us treat the atypical forms of BPPV. It will also help us determine if there is another vestibular condition at play, mimicking BPPV.

What are Ewald’s...

Repeat Positional Testing - Are You Willing To Risk It For The Biscuit?

Mar 11, 2023

A recent Instagram post caught my eye as it indicated that given a particular study, clinicians should not repeat positional testing after performing a canalith repositioning technique for BPPV. The reason for this, I believe, was due to the risk of causing the loose otoconia to fall right back into one of the canals.

To be honest this post surprised me. I just assumed that it was common practice now-a-days to repeat positional testing to see the effect of treatment. Don’t we want to evaluate the effect of our treatment? Then, when I went back to find that post and hopefully get the study they were referring to, it was buried deep in the social media abyss.

I was a bit disappointed...
