About

The objective of this study was twofold: first, to assess the validity and reliability of the 2 Minute Step Test (2MST) in patients with fibromyalgia; and second, to explore its relationship with objective assessment methods, specifically the 2 Minute Walk Test (2MWT) and the 6 Minute Walk Test (6MWT). Additionally, the study aimed to investigate the correlation between the 2MST and quality of life as well as chronic fatigue levels using the Fibromyalgia Impact Questionnaire (FIQ) and the Fatigue Severity Scale (FSS).

Full description

This cross-sectional study will include 55 female patients aged 18-65 who will be diagnosed with fibromyalgia according to the American College of Rheumatology 2010 Diagnostic Criteria. Demographic characteristics of the patients will be documented. The extent of impact on patients' quality of life will be evaluated using the Fibromyalgia Impact Questionnaire (FIQ), while the severity of chronic fatigue will be measured using the Fatigue Severity Scale (FSS). The intensity of chronic pain experienced by patients will be expressed using the Visual Analogue Scale (VAS). All patients will undergo an initial assessment using the 2-Minute Step Test (2MST), 2-Minute Walk Test (2MWT), and 6-Minute Walk Test (6MWT). To assess test-retest reliability, the 2MST will be repeated with a 7-day interval between assessments.
