Evaluation of Fingertip Precision Pinch Force in Fibromyalgia Patients

June 25, 2025 updated by: Dilara Ekici Zincirci

Evaluation of Fingertip Precision Pinch Force During Carrying in Fibromyalgia Patients.

This study aims to evaluate the force used by fibromyalgia patients during a task compared to healthy volunteers and to evaluate its relationship with fatigue seen in these patients.

Detailed Description

Fatigue is a common symptom in fibromyalgia patients and it is known that these patients have decreased muscle strength compared to healthy volunteers. The aim of this study was to evaluate whether the minimum force to be applied during carrying is different in fibromyalgia patients compared to healthy volunteers.
