Fibromyalgia patients exhibit reduced handgrip strength compared to healthy individuals. Grip strength did not differ between moderate and severe fibromyalgia, but was linked to body mass index and myalgia severity.
Area of Science:
- Rheumatology
- Neurology
- Physical Therapy
Background:
- Fibromyalgia (FM) is a chronic condition characterized by widespread pain and fatigue.
- Assessing physical function, such as handgrip strength, is crucial for understanding the impact of FM.
Purpose of the Study:
- To compare handgrip strength between female fibromyalgia patients and healthy controls.
- To investigate the relationship between clinical factors and fibromyalgia disease severity.
Main Methods:
- A case-control study involving 25 female FM patients and 23 healthy females.
- Handgrip strength was measured using a Jamar® dynamometer.
- Fibromyalgia severity was assessed using the Fibromyalgia Impact Questionnaire (FIQ).
Main Results:
- Fibromyalgia patients demonstrated significantly lower handgrip strength than healthy controls (p=0.011).
- A negative correlation was observed between handgrip strength and body mass index in FM patients (r=-0.510, p=0.037).
- No significant difference in handgrip strength was found between moderate and severe FM groups based on FIQ scores.
Conclusions:
- Fibromyalgia is associated with diminished handgrip strength.
- Handgrip strength is not a distinguishing factor between moderate and severe fibromyalgia.
- Body mass index and myalgia severity are correlated with fibromyalgia impact.

03:05Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...
