Is there testing that can provide you with an objective and clinical diagnosis of
myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS)?
Although there is currently no single diagnostic or confirmatory lab test, such as a blood test or scan, for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), cardiopulmonary exercise testing (CPET) makes it possible to objectively measure whether a client has given a maximal effort while exercising.
Clients can attend a traditional one-day test or the specialized two-day exercise test protocol. The two-day protocol repeats the maximal exercise test 24 hours after the first, and is used specifically to assess whether physical exertion on day one impairs functional capacity on day two, the physiological signature of post-exertional malaise (PEM), the core symptom of ME/CFS.
If positive, a two-day CPET offers a validated, physiological demonstration of the abnormal recovery response that defines post-exertional malaise. This can serve as objective supporting evidence in the diagnostic process, and is also used in disability and functional capacity assessments.
In this webinar, you will learn
- that CPET testing can provide you with an objective and clinical diagnosis of ME/CFS
- that it is possible to optimize exercise testing and rehabilitation strategies for ME/CFS, focusing on post-exertional malaise
- that the testing can also provide you with guidance on how to improve your health without causing more fatigue and malaise.
The webinar will last approximately 90 minutes.
- 5-10 minute introduction
- 40-minute presentation
- 10-minute break
- up to 30 mins of Q&A

About the Presenters
Cory Fagan, M.Sc. Kin
TCR is a lifelong dream for Cory that began in 2006. His vision was to build a sport science center to help people achieve their goals. A place for people to connect and participate in movement.
Cory has been involved in the fitness, health and sport training industry for the past 25 years. Academically, Cory received an honours degree in Physical Education in 1996 and a Master of Science Degree in Kinesiology in 2000, both from the University of Calgary. His studies focused on advanced methodologies of exercise testing and strength training for athletes. His career began as a strength and conditioning coach at the UofC and then the Southern Alberta Institute of Technology (SAIT) Athletics.
Although Cory’s primary clientele are athletes, he has a background and interest in chronic illness, including cancer survivors and patients with ME/CFS and FM. Incremental Blood Lactate testing assists patients in determining their anaerobic threshold and exercise capacity. Cory provides recommendations for incremental training based on individual capacity.
Eleanor Stein, MD
Dr. Eleanor Stein brings a rare combination of over 35 years of lived experience and medical expertise in myalgic encephalomyelitis, chronic fatigue syndrome, fibromyalgia, environmental sensitivities, long COVID and chronic pain.
She became ill with ME, CFS, FM and MCS in 1989. Since then, she has experienced, studied, and treated the full alphabet of related conditions, including joint hypermobility, orthostatic dysfunction and mast cell activation syndrome. She has personally tried hundreds of approaches, attended hundreds of medical conferences, and reviewed thousands of peer-reviewed papers to determine what works best for the greatest number of people.
Since retiring from medical practice at the end of 2022, Dr. Stein has dedicated her time to integrating emerging research in neuroplasticity, hormesis, circadian biology, and related fields. While traveling in her camper van, she continues to study and translate this research into practical, accessible programs designed to make the healing journey easier, safer, and more effective.
