Abstract
Background
Fibromyalgia is characterized by widespread pain, fatigue, sleep and cognitive symptoms. It overlaps clinically with functional motor disorder (FMD), yet its prevalence and impact in FMD remain uncertain.
Objective
To determine the prevalence of fibromyalgia in FMD using the current criteria and evaluate its effects on motor symptoms and health-related quality of life (HRQoL).
Methods
A total of 138 consecutive FMD patients completed the Fibromyalgia Survey Questionnaire, subjective motor ratings and HRQoL measures. Motor impairment was assessed using the Simplified FMD Rating Scale, and physical/psychiatric comorbidities and medication use were recorded.
Results
Fibromyalgia was present in 44.9% of patients (95% CI: 36.5–53.6%). Those with fibromyalgia had more severe motor symptoms, lower HRQoL and greater medication use. Higher fibromyalgia severity, S-FMDRS, and psychiatric comorbidity were independent predictors of lower HRQoL.
Conclusions
Fibromyalgia is common in FMD and associated with worse clinical outcomes, supporting systematic screening and integrated management.
