Brief summary

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.

Interventions

OTHERisokinetic muscle strength measurement

Wrist isokinetic eccentric flexor and extensor peak Torque and fatigue will be measured at the angular velocity of 180°/s

OTHERMinimum pinch force measurement

the minimum fingertip pinch force required to hold a constant weight will be measured

Study design
