Persistent Postural Perceptual Dizziness (PPPD or 3PD) is a chronic functional vestibular condition that can be a challenge to manage. While it isn’t caused by structural damage or psychiatric disorders, it’s one of the most common reasons people experience long-term dizziness. This condition is especially prevalent in specialized dizziness centers, where understanding PPPD can make a big difference in patient care. Let’s take a closer look at its symptoms, history, and what healthcare providers need to know. We hope that in sharing what we have found, this helps you better understand this challenging condition and improve patient outcomes.

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...

Maintaining mobility and activity levels in patients with balance issues is essential for their overall well-being. Falls are a leading cause of losing independence in older adults, making fall prevention a key priority. As healthcare providers, we must balance the need to reduce fall risks with keeping patients active. This is where ambulatory aids like walking, Nordic, and trekking poles can make a significant difference. In this post, we’ll review the benefits, differences, and sizing of these poles, and how to determine which is the best option for your patients.

Designed to provide stability, they can help patients maintain balance ...

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...

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.

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.

What is Alice In Wonderland Syndrome or AIWS?

Alice in Wonderland Syndrome (AIWS) is a rare and intriguing neurological condition, often linked to migraines. But, it can also be triggered by ...

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.

What is Autoimmune Inner Ear Disease (AIED)

Autoimmune Inner Ear Disease (AIED) is a rare condition where the immune system mistakenly attacks the structures of the inner ear, particularly ...

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 t...

Do you or a patient of yours experience dizziness with coughing, loud sounds, or with sudden altitude changes? If so, the symptoms maybe due to a perilymphatic fistula.

Let’s cover the 5 W’s of what a perilymphatic fistula is. That way we will have a better understanding of what it is, what causes it, and treatment options.

What is a Perilymphatic Fistula?

A perilymphatic fistula is a hole or defect in one of the two thin membranes of the inner ear, being the round and oval window.

Function of the round and oval window

These two membranes allow for pressure changes in the inner ear. Specifically, the oval window allows for the vibration from the stapes (smallest bone in your body) in t...

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 common co...
