Changes in the mechanical properties and pressure pain thresholds of muscles in patients with fibromyalgia and their relationship with clinical parameters: a case-control study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe association between fibromyalgia and changes in muscle mechanical properties is unclear. The primary objective of this study was to compare the mechanical properties (tone, stiffness, and elasticity) of the upper trapezius (UT), extensor carpi radialis brevis (ECRB), and medial gastrocnemius (MG) muscles between patients with fibromyalgia (PwFM) and healthy controls. The secondary objective was to investigate the association between muscle mechanical properties and relevant clinical parameters.
methodsTwenty-nine women and two men with fibromyalgia, and 31 age-matched healthy controls were included in this study. Muscle mechanical properties were assessed using myotonometry (MyotonPRO
resultsMuscle frequency (tone) and dynamic stiffness in the UT, ECRB, and MG were significantly higher in the PwFM group compared to controls (p < 0.05). Effect sizes were strong for the UT (|r|≥0.5), weak to moderate for the ECRB (|r|=0.293-0.306), and weak for the MG (|r|=0.293). No significant between-group differences were observed in logarithmic decrement (elasticity) (p > 0.05). In the PwFM group, a moderate positive correlation was found between the frequency of the MG muscle and its PPT (r = 0.508, p = 0.003).
conclusionThe present study revealed that the tone and stiffness of the UT, ECRB, and MG muscles were increased in PwFM. These findings indicate that altered muscle mechanical properties were associated with fibromyalgia and may warrant consideration in future research exploring clinical management approaches.
