Researchers hope to provide chronic fatigue syndrome answers

19.12.2007
New kinesiology research hopes to provide definitive test for CFS
One of the most difficult things for people suffering from Chronic Fatigue Syndrome (CFS) is that many believe the condition to be a psychological, not physical affliction.

New research by the Faculty of Kinesiology hopes to measure one of the syndrome’s most obvious symptoms — information that could help doctors in the diagnosis CFS.

“Diagnosis of the syndrome, generally follows eliminating every other possible cause, which leads some to speculate that the condition isn’t real,” says Dr. Brian MacIntosh. “One thing we know is that CFS sufferers feel profound fatigue and worsening of other symptoms following even moderate physical activity. Using our expertise in the field of exercise physiology we believe we can measure this post exertion malaise and say with certainty if an individual has recovered from exercise or if that activity is making them even more fatigued.”

MacIntosh, who is the Faculty of Kinesiology’s Associate Dean of Graduate Studies, is an expert in the area of muscle fatigue. Much of his research has centered on high-performance athletes in peak physical condition, however he says that this research fits in well with his overall area of interest.

“The tools we have developed in high performance sport are perfectly suited to track muscle fatigue in this application so without question we will be able to get some concrete answers,” he says.

The research trial will put CFS patients on a stationary bike to perform a VO2 Max test – similar to trials used to evaluate the fitness level of professional athletes. The individual will pedal to the point of fatigue, at which point researchers will take several measurements including a blood sample in which lactate will be quantified. The next day the patient will return and follow the same workout protocol.

“Most healthy individuals should be able to easily match their performance from the previous day,” MacIntosh explains. “Since CFS patients by definition report profound fatigue from even moderate physical exertion and take greater than 24 hours to recover, we would expect to see a decrease in their physical performance and we should be able to measure that in several ways.”

This work may shed some light on whether the fatigue experienced by people with CFS is primarily in the muscles or in the nervous system. MacIntosh believes that the results of this work could lead to a definitive diagnosis of CFS, giving another tool in the otherwise limited toolbox of diagnostic tests and perhaps, more importantly, shed some light on the broader issue of human muscle fatigue.

“We've all experienced fatigue in our lives," says MacIntosh. "For example when we have the flu or any similar illness, we feel that fatigue makes our arms and legs feel like they’re made of lead... I’m hoping that this research may lead to a greater understanding of human muscle fatigue in general.”

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
