A common feature that most fibromyalgia sufferers present is a diffuse pain that affects a large part of the body. This disturbing symptom is usually accompanied by morning joint stiffness, paresthesias in the hands and feet, ie tingling sensation and numbness, sleep disturbances and especially a feeling of fatigue and fatigue that accompanies them during the day. This fatigue contributes to fibromyalgia having a poor tolerance for the effort that affects up to 90% of patients.
That is why a study conducted by a team from the University of Granada, and published in January 2011 in the journal Archive of Physical Medicine and Rehabilitation, analyzed the resistance that these patients present in their hands, to be able to use as a complementary tool for the evaluation of the severity of fibromyalgia in women.
The aim was to determine the capacity of the strength test in the hand, in discriminating between the presence and absence of fibromyalgia and the severity of it in 81 women with the disease and 44 healthy women. They measured the resistance of the force in the hand with a test of the maximum isometric force, with the help of a hand dynamometer. Women were classified according to the score obtained in: moderate fibromyalgia (<70) and severe fibromyalgia (70 or more). The observed results were:
The threshold strength resistance in the hand that discriminates best between the presence and absence of fibromyalgia was 23.1 kg.
The threshold that best discriminates between severe and moderate fibromyalgia was 16.9 kg.
A resistance of the hand strength of 23.1 kg or less was associated with having a 33.8 times higher chance of suffering fibromyalgia after delineating age.
In the fibromyalgia group, a force strength in the hand of 16.9 kg or less was associated with a 5.3 times higher chance of suffering from severe fibromyalgia.
The conclusions of these researchers are: that the resistance of the force in the hand is reduced in women with fibromyalgia, as well as in people with severe fibromyalgia with regard to their partners with moderate fibromyalgia. They also point out that those women who do not meet these proposed standards can guide the doctor to make a good diagnosis, because it would be used as a useful and informative tool.
Have you noticed that you have less resistance and strength in your hands than your friends / family? In which aspects of daily life is a disability?
We hope that you share your impressions with us, which we will send to our members patients.
