Assessment of hand function and disability in fibromyalgia

Fibromyalgia, a potentially debilitating chronic pain syndrome, is a chronic disease. We aimed to compare the hand function of fibromyalgia (FM) patients and healthy individuals and to demonstrate the relationship between hand disability and FM.

The study was consisted of 40 female patients with FM and 30 healthy controls. All participants were evaluated for pain threshold measurements, handgrip strength, and pinch strength. Functional states, hand disability, and hand skills and coordination were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) form, the Disability of Arm-Shoulder-Hand (DASH) questionnaire and the Purdue Pegboard Test, respectively.

Handgrip strength values, DASH score, lateral pinch strength test, Pegboard placement time, and Pegboard collection time of the patient group were significantly lower than those of the control group (all p < 0.05). A negative correlation was found between FIQ score and handgrip strength, two-point pinch strength test, three-point pinch strength test, and lateral pinch strength test in patients with moderate FM (all p < 0.05). Furthermore, a correlation was observed between DASH score and handgrip strength, lateral pinch strength test, Purdue Pegboard placement time, and Purdue Pegboard collection time in patients with moderate FM (all p < 0.05).

Our results show that hand function was decreased in patients with FM compared to healthy controls and decreasing hand function was influenced by FIQ score. As a result, the evaluation of hand function should be taken into consideration in the management of FM.
