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.

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...

Q-collar: Next Big Thing for Concussion Prevention?

Jan 04, 2023

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...

Concussions & Football, Getting Back to Some of the Basics

Oct 05, 2022

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.

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.

"Back To The Basics" With Concussions

Feb 02, 2021

Over the past decade, there has been a significant increase in research published regarding concussions. This information has allowed care providers to better understand the pathophysiology and natural history of concussions. Treatment protocols have also been published to assist care providers in the management of concussions.

As with anything, with this increase in published information, there is a corresponding increase in misinformation and/or poor quality research. This has lead to conflicting information and confusion for both the health care provider and the patient.

Given this, we have decided to clear up some of this confusion in regards to concussions by getting “back to...
