Extremely high muscle tension causes pain with fibromyalgia

People with fibromyalgia have a much higher muscle tension than people without fibromyalgia. Extreme muscle tension can be the cause of the often severe muscle pain associated with fibromyalgia. That is the conclusion of the research conducted by Dr. Ewa Klaver-Król of Twente. High muscle tension develops in people with fibromyalgia without having to use their muscles. Research is a new step in a better understanding of fibromyalgia.

Ewa Klaver-Król is a neurologist and researcher at the Roessingh Research and Development Institute (RRD) in Enschede. He specializes in the investigation of fibromyalgia and other disorders that are medically difficult to explain. His research on muscle activity in fibromyalgia involved 22 women with fibromyalgia and 21 women without fibromyalgia.

Significantly high muscle tension
His research shows that people with fibromyalgia have much higher muscle tension than people without fibromyalgia. Ewa Klaver: ‘We measure muscle tension in the same way in women with fibromyalgia and in women without fibromyalgia. They had to keep the arm in a certain position and, sometimes, they did it and other times they did not get a weight on the hand. Our measurements show that women with fibromyalgia have much greater muscle tension, even when no force is used. ‘

Overactive muscular membrane
“In our research we measure muscle tension on the surface of the muscle, the so-called muscle membrane. What appears is mainly the muscular membrane itself that becomes overactive in people with fibromyalgia. It is important to know this because the signal is transmitted to the muscles through the muscular membrane to contract. When the muscle membrane is overactive, the muscle tightens too easily without being necessary.

Explanation of complaints.
The results of Ewa Klaver’s research establish a clear link with the complaints of people with fibromyalgia. ‘If your muscles tense too often, for too long and also unnecessarily, it can cause pain, cramps and fatigue. These are the symptoms that people with fibromyalgia recognize very well. Therefore, our investigation can provide an explanation for the complaints. “

Better understanding of fibromyalgia.
Ewa Klaver-Król’s research is a new step to better understand fibromyalgia. “I think the cause of fibromyalgia is in the nervous system. Several studies have already shown that in people with fibromyalgia the signals in the nervous system are not sufficiently inhibited. The muscle and the muscular membrane are parts of that nervous system. It is likely that the membrane has been mistakenly given the “squeeze” signal, which causes high muscle tension, with all its consequences for people with fibromyalgia. “
