Physical Activity and Work Ability in University Staff

The goal of this observational study is to explore the relationship between leisure-time physical activity (LTPA) and work ability in university staff, with a focus on occupational physical activity (OPA) and gender. The main question it aims to answer is: How does leisure-time physical activity (LTPA) influence work ability in university staff, considering their occupational physical activity (OPA) and gender? Participants from the University of Alcalá will complete an online survey, which includes sociodemographic data and validated questionnaires on LTPA, OPA, work ability, musculoskeletal disorders, health-related quality of life, and workload.

Assessment of the Functional Capacity of Patients with Fibromyalgia: Clinical Validity

Fibromyalgia is one of the main causes of chronic pain without a specific etiology, affecting 8% of the Spanish population, especially women. Its most characteristic symptoms include generalized pain, fatigue, difficulty falling asleep, joint stiffness, anxiety, and depression. Due to the lack of objective data confirming the condition and the subjectivity of the symptoms, the current diagnosis is purely clinical. Moreover, despite the significant impact on the quality of life of those who suffer from it, there is a lack of scientific evidence to assess the degree to which it affects their functional and work capacity. This concept is gaining relevance in the growing context of patients seeking work disability. Thus, due to the lack of international consensus and standardized protocols, this study hypothesizes that the functional capacity of Spanish women with fibromyalgia, aged 30 to 64, evaluated with various validated tests such as the six-minute walking test (6MWT), handgrip strength dynamometry, and the 8-foot up \& go, correlates directly with their quality of life, physical activity measured by accelerometry, and social and psychological impact, provided there is no economic benefit. Therefore, the primary aim of this research is to validate a standardized protocol for evaluating the functional and work capacity of Spanish women with fibromyalgia and to assess its correlation with quality of life, physical activity, and psychosocial impact. The study will include a total sample of 160 women, divided into four groups of 40 participants: women with fibromyalgia who are actively working, women with fibromyalgia on sick leave, women with fibromyalgia with permanent work disability (officially recognized by the National Institute of Social Security, INSS), and a control group of healthy women. The patients will be required to attend in person to complete the full protocol, with a one-week interval between sessions. Subsequently, two follow-ups will be conducted at 6 and 12 months, where the work situation will be reassessed, and questionnaires will be administered. The protocol includes the following variables for study: age, weight, height, marital status, country of origin, socioeconomic level, educational level, occupation, work situation, generalized pain index questionnaire, symptom severity questionnaire, fibromyalgia impact questionnaire, allodynia test, six-minute walking test, 8-foot up and go, handgrip strength dynamometry, tender points, false points, SF-36 questionnaire, Hospital Anxiety and Depression Scale, multidimensional perceived social support scale, and accelerometry. The aim of this study is to analyze in greater depth the validity of the tests currently used in clinics to objectively assess the functional capacity of patients with fibromyalgia. In this way, this study will become the first to present and evaluate the validity and reliability of a protocol for assessing functional capacity. If the proposed hypothesis is proven, these tests and evaluation methods will be highly useful for systematic incorporation into the routine of functional capacity assessment services, as well as in daily clinical practice.
