Sedentary Status and Multidimensional Outcomes in Fibromyalgia

Summary

Fibromyalgia syndrome (FMS) is a chronic condition characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and functional limitations. Pain, fatigue, and fear of movement often lead individuals with FMS to adopt sedentary behaviors, which may further exacerbate symptoms and reduce physical capacity. Factors such as impaired body awareness, reduced respiratory muscle strength, kinesiophobia, central sensitization, poor functional status, and sleep disturbances play an important role in disease severity and quality of life in individuals with FMS.

Although physical inactivity is common in fibromyalgia, limited evidence exists regarding the differences in these multidimensional clinical parameters between sedentary and non-sedentary individuals with FMS. Therefore, the aim of this study is to compare body awareness, respiratory muscle strength, kinesiophobia, central sensitization, functional status, and sleep quality between sedentary and non-sedentary individuals diagnosed with fibromyalgia syndrome. The findings of this study may contribute to a better understanding of the impact of sedentary behavior on clinical outcomes in fibromyalgia and help guide more comprehensive and individualized rehabilitation approaches.

Conditions

• Fibromyalgia
• Sedentary Behavior
• Kinesiophobia
• Central Sensitisation

Interventions

OTHER

Assessment Only

No therapeutic intervention will be applied in this study. Participants will undergo a comprehensive assessment to evaluate clinical and functional characteristics. Assessments will include body awareness, respiratory muscle strength, kinesiophobia, central sensitization, functional status, sleep quality, and physical activity level. All evaluations will be conducted at a single time point using validated clinical measurement tools and self-reported questionnaires. The purpose of these assessments is to compare sedentary and non-sedentary individuals with fibromyalgia syndrome in terms of multidimensional clinical outcomes.
