The objective was to determine the strength of the strength test in the hand, in discriminating between the presence and absence of Fibromyalgia Rheumatic Diseases and the severity of the same in 81 women with the disease and 44 healthy women.They measured the resistance of the force in the hand with a maximum isometric force test, with the aid of a hand dynamometer. The women were classified according to the score obtained in: Moderate fibromyalgia (<70) and severe fibromyalgia (70 or more). The results observed were:The strength threshold in the hand that best discriminates 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 strength of the hand force of 23.1 kg or less was associated with a 33.8-fold higher probability of having Fibromyalgia Rheumatic Diseases after age delimitation.In the fibromyalgia group, a strength of the hand force of 16.9 kg or less was associated with a 5.3-fold higher probability of suffering from severe fibromyalgia.The conclusions of these investigators are: that resistance of the force in the hand is reduced in women with Fibromyalgia Rheumatic Diseases, as well as in those with severe fibromyalgia compared to their partners with moderate Fibromyalgia Rheumatic Diseases.They also point out that those women who do not comply with these proposed standards can guide the doctor to make a good diagnosis, as it would be used as a useful and informative tool.
