Abstract
Reduced functional capacity is a common characteristic of fibromyalgia (FMS). We aimed to investigate the relationship between functional status and body mass index (BMI) in a population with and without FMS. A pilot case–control study was performed in 34 women with FMS and 22 healthy controls which were classified according to their BMI. The main outcome measures were: Balance (MiniBestest, One Leg Stance Test), functional mobility (Timed up and Go), physical disability (Health Assessment Questionnaire Disability Index), spinal range of motion (Spinal Mouse), level of physical activity at work (Leisure Time Physical Activity Instrument), and home and leisure time (Physical Activity at Home and Work). Statistical differences were observed between overweight/obese healthy controls and women with FMS for several indicators of functional capacity. FMS patients reported worse dynamic (p = 0.001) and static balance (right: p = 0.002, left: p = 0.001), poorer functional mobility (p = 0.008), and higher levels of physical disability (p = 0.001). Functional status is altered in FMS women compared to the healthy control group, independently of nutritional status; therefore, BMI is unlikely to play a main role in functional capacity indicators in postmenopausal FMS women. Only dynamic balance seems to reduce the obesity status in this population.

Since reduced functional capacity is a common characteristic of FMS, and taking into account that the prevalence of overweight and obesity is high in FMS patients, especially when women reach a postmenopausal state, the aim of this study was to investigate the relationship between functional status by assessing balance, functional mobility, physical disability, hamstring flexibility, spinal range of motion, level of physical activity at work, home, and leisure time, and body mass index (BMI) in a population of overweight/obese and normal-weight women with and without FMS
A total of 34 women with FMS and 22 healthy controls were included in this study
Summary
Fibromyalgia syndrome (FMS) is a multicomponent and chronic illness whose etiology is still unknown. Current diagnostic criteria published by the American College of Rheumatology (ACR). Include both pressure and widespread pain, which cannot be explained by the presence of degenerative or inflammatory disorders. FMS includes other conditions such as cognitive behavior, restless sleep, fatigue, and somatic symptoms [1]. FMS is present in all ethnic groups [2], climates, and cultures, with the prevalence being higher in women. To 5%, and up to 15.7% in a clinical setting. In Spain, the estimated prevalence is 4.2% in women and
