Long COVID-19 can be a confusing problem to navigate. Long Haulers feel as though they have little control over their symptoms. Severe fatigue, breathlessness, brain fog, pain and more, can worsen in what seems like a random fashion. We understand that even mild physical activity can make your symptoms worse. Cornerstone’s program helps you understand your symptoms, and regain control while slowly increasing activity at the rate your body can tolerate.

Cornerstone’s Long COVID program was developed in consultation with researchers and experts on the front lines, treating COVID patients. We are the first program of our kind. We leverage the power of virtual consultations, data from wearables (Apple watch, fitbit etc..) and symptom monitoring technology. We provide easy to follow guidelines to help you recover while minimizing exacerbation of symptoms, commonly referred to as “crashes”. 

We acknowledge that research and knowledge about Long COVID continues to evolve. We continue to work with medical professionals and researchers from many disciplines to continue to learn about the condition. We encourage patients to have a medical and rehabilitation team working together to help manage the condition.

Post COVID-19 Syndrome Symptoms

NOTE:  Post Acute COVID-19 patients may not have all of these symptoms.
Each person’s presentation is unique and requires a customized treatment plan.


How Does Cornerstone’s Long COVID Program Work?

Anyone in Ontario can Access Our Help

Cornerstone’s Long COVID Program can be delivered exclusively using video conferencing. This means anyone in the province of Ontario can access this cutting edge program. For patients in the Greater Toronto Area we can do in-person consultation on an as-needed basis.

We Start With Comprehensive Assessment. 

We use tools designed to capture and measure the complete spectrum of symptoms that COVID Long Haulers experience, and we track your progress over time. Every patient has different symptoms and requires a different approach. By fully understanding what you are experiencing we can tailor our treatment plan to help you. 

A positive COVID-19 test is not required. Many patients who contracted COVID-19 were not able to access testing to confirm their condition. We strongly recommend that you also have your physician involved in your care. We provide detailed information to your medical team to help them understand your condition and treat problems as they arise. We support the rest of your medical team.

Insights From Wearable Technology

Making sense of your symptoms and the recovery process requires a lot of detailed information. Our patients use wearable technology like apple watch, fitbit etc… We are able to access and analyse the data from your program approved device to understand how your body is responding and to guide rehabilitation recommendations. 

We will provide a letter recommending a wearable device for the purposes of Long COVID Treatment. Some insurance companies may cover part or all of the cost.

If you are unable to access a wearable device, we can still work with you. Our clinicians work with Long COVID patients every day. We will take a more conservative approach to your treatment plan and progress you based on how your symptoms are responding. While this approach is less precise it may be required to fit some patients’ budgets. 

Symptom Monitoring Technology

Our team at Cornerstone is able to collect symptom information from patients at regular intervals through an easy to use web platform. This allows us to track symptoms over time and correlate them to your wearable data and activity levels.

Treatment Your Body Can Handle

The power of analyzing symptom information with biometric data allows us to progress your rehab plan at a pace your body can handle enabling you to take advantage of recovery while minimizing the risk of worsening your condition. Our Physiotherapists use all of this information to provide you with clear and easy to understand instructions. You will always know what you should be doing to make optimal progress.

A Global Approach To Covid-19 Recovery

We help you identify things that you could be doing to support your recovery. Many factors influence recovery. Sleep, nutrition, hydration and psychological factors all have an impact. Where necessary we will refer you to another professional, otherwise we can provide evidence based education to help you fine tune your recovery habits.

What our Long COVID patients say...

Cornerstone has been my saving grace. In March I was badly suffering from long COVID and I was in such a depressive mental space. Melissa literally saved me with her compassion, and constant support. I’ve made so many incredible strides physically and mentally. It’s now the end of July and I’m able to actually get out of bed and do things with careful pacing and instructions! I’m forever grateful.

What our Long COVID treatment patients say...

I highly recommend anyone struggling with Long COVID to consider Cornerstone, especially those who’s doctors may not have taken them seriously. Giacomo was great to work with, he helped customize a recovery plan with me and monitored my symptoms via my smart watch. We could then analyze and monitor any trends to adjust my activity level. Thank you very much Giacomo and Cornerstone!

Markham, ON

What our COVID rehabilitation patients say...

Melissa and Adam have been wonderful to work with. The instructions they give are easy to follow and understand.  It is clear that they spend a lot of time and effort designing a personal activity plan that is based on feedback from my own data. The support that they have provided me has been very reassuring. They are easily reached, and quick to answer all of my questions.

Claire C.

Cornerstone Physiotherapy is providing an invaluable resource to patients suffering from mild to severe autonomic dysfunction, particularly postural orthostatic tachycardia syndrome, a largely misunderstood and under-diagnosed condition. The team has a deep understanding of the physiology of the potentially debilitating symptoms and gradual treatment options on an individual basis. What a cornerstone of guidance and support for so many patients.

Kristen Yu

What our Long COVID patients say...

Working with Cornerstone virtually for long COVID care and they are really helpful. They take the time to listen to what is going on for me, as this condition is unique for each individual. They stay up to date on research and try their best to find solutions to help me feel better. Their guidance with pacing has been great and given me a path that clears some of the mud around navigating this condition.
