Safe exercise for migraine sufferers

Many patients who suffer from migraines avoid taking aerobic exercise because they are afraid that the physical activity may bring on a serious migraine attack. Researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, have now developed an exercise programme that can improve fitness among migraine sufferers without aggravating this painful condition.

Patients who suffer from migraines are often advised to take exercise, but to date no studies have been conducted to show that exercise actually helps guard against migraine attacks. No exercise programme has so far been scientifically proven to be safe for migraine patients.

"We know that everyone benefits from a little exercise, but if you're convinced that a session at the gym will end up with you being confined to bed with a thumping headache and nausea then it's hardly surprising that people give it a miss," says Jane Carlsson, Professor in Physiotherapy at the Sahlgrenska Academy.

In the study, which is being published in the latest issue of the scientific journal Headache, some twenty migraine sufferers were asked to follow a special exercise programme three times a week for three months. The programme involved using an exercise bike under the guidance of a physiotherapist.

"We could see that those who participated in the study were much fitter after the training period, since their ability to absorb oxygen increased considerably," says physiotherapist Emma Varkey, one of the researchers behind the study.

Only one of the patients suffered a migraine attack that was directly linked to the training session. "Now that we've been able to show that the risk of increased frequency of attacks in connection with this type of exercise is extremely small, we can study whether exercise can be used to prevent or alleviate migraine attacks. "We have already initiated a new study in which we plan to compare the results against a control group," says Mattias Linde, neurologist at Cephalea Headache Centre and researcher at the Sahlgrenska Academy.

Up to 10 percent of all Swedes suffer from migraines. A migraine is a recurring, thumping headache, which intensifies and causes nausea, vomiting and increased sensitivity to light and noise. Attacks can last for anything from a couple of hours to several days. The cause of migraines is unknown, but the condition is thought to be hereditary.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
