- Differences between Portuguese and Brazilian Patients with Fibromyalgia Syndrome: Exploring the Associations across Age, Time of Diagnosis, and Fatigue-Related SymptomsPublication . Alvarez, Marcos; Albuquerque, Maria Luiza L.; Neiva, Henrique P.; Cid, Luis; Rodrigues, Filipe; Teixeira, Diogo S.; Monteiro, DiogoThe aim of the study was to explore the differences between Brazilian and Portuguese patients with fibromyalgia (FM) syndrome in their experience of fatigue, and to measure differences in the perception of fatigue as a function of age and duration of the diagnosis. In total, 209 Portuguese women aged between 21 and 75 years (M = 47.44; SD = 10.73) and 429 Brazilian women aged between 18 and 77 years (M = 46.51; SD = 9.24) were recruited to participate in the present study. Participants completed the Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 items (MDF-Fibro-17), a specific tool to measure the level of five components of FM-related fatigue. Results showed greater perception of all the components of fatigue in the Brazilian sample. No significant differences were found related to age and duration of FM diagnosis. The multifaceted nature of FM and cultural differences suggests that individualized treatment programs may be necessary to reduce fatigue-related symptoms in patients with this syndrome.
- Effects of strength training in fibromyalgia on balance, neuromuscular performance, and symptomatic analysis: a 12-week study protocolPublication . Albuquerque, Maria Luiza L.; Monteiro, Diogo; Alvarez, Marcos; Vilarino, Guilherme Torres; Andrade, Alexandro; Neiva, Henrique P.Fibromyalgia affects skeletal muscles presenting with muscle stiffness, pain, and fatigue. The exercise practice is wellstabilized and suggested for the reduction of symptoms. However, there are some gaps in the literature related to balance and neuromuscular performance in a strength training protocol. The aim of this study is to structure a protocol to verify the effects of strength training applied over a short period, on balance, neuromuscular performance, and fibromyalgia symptoms. Additionally, we intend to analyze the effects of a short period of cessation of training. Participants will be recruited through flyers, internet advertisements, clinical referrals, health professionals, and email outreach. Volunteers will be randomly assigned to the control group or experimental group. Before the training period, symptoms (Fibromyalgia Impact Questionnaire, Visual Analog Scale), balance (force plate), and neuromuscular performance (medicine ball throw and vertical jump) will be assessed. Participants in the experimental group will perform strength training twice a week (50 min each), on alternate days, for 8 weeks (16 sessions). Then, 4 weeks of detraining will be completed. This training program will be carried out online, using real-time videos, and the participants will be divided into two groups with different schedules. The Borg scale will be used to monitor perceived effort in each session. There is a gap in the literature about exercise prescriptions for fibromyalgia. The supervised online intervention enables a wide range of participation. The strength exercises used (without the use of external materials and/or machines) and load (few repetitions per set) represent a novelty to training programming. Moreover, this training program respects the limitations and individuality of the volunteers, providing exercise adaptations. With positive results, the present protocol could be an easy-to-apply guideline with clear instructions on the details related to exercise prescription. Also, ensure the effectiveness of a low-cost and feasible treatment, especially for fibromyalgia patients.
- Exploring the Relationship between Fibromyalgia-Related Fatigue, Physical Activity, and Quality of LifePublication . Alvarez, Marcos; Albuquerque, Maria Luiza L.; Neiva, Henrique P.; Cid, Luis; Rodrigues, Filipe; Teixeira, Diogo S.; Matos, Rui; Antunes, Raul; Morales-Sánchez, Verónica; Monteiro, DiogoThe symptoms of fibromyalgia are varied, including general muscle pain and pain at specific points (also called tender points), excessive fatigue, anxiety, depression, and some psychological problems that can have a negative impact on quality of life. Physical activity is a widely used option by health professionals to alleviate the effects of this syndrome. However, there is no clear information on the possible mediating role of physical activity in the relationship between fibromyalgia-related fatigue and quality of life. Therefore, this study aims to evaluate the relationship between fibromyalgia-related fatigue and quality of life, and to investigate the mediating role of physical activity in patients with this syndrome. Methods: In a cross-sectional study, 237 Portuguese women aged 28 to 75 years (M = 49.12; SD ± 8.87) and 117 Brazilian women aged 20 to 69 years (M = 46.72; SD ± 8.38) were recruited to participate in this study. These patients completed three valid and reliable questionnaires related to the assessment of fibromyalgia-related fatigue (MDF-Fibro-17), physical activity (IPAQ), and quality of life (SF-36). Results: Both samples had scores above the midpoint for all dimensions of fibromyalgia-related fatigue and scores below the midpoint for quality of life. Physical activity had no mediating effect in either sample, as the total indirect effect was not significant. Conclusions: Physical activity does not mediate the relationship between fatigue and quality of life. However, the results also show that the fatigue dimensions associated with fibromyalgia had a negative and significant association with physical and mental health indicators in both samples. Thus, patients with FM with higher scores on fatigue-related symptoms might suffer more from physical and mental health, both of which are related to quality of life
- Resistance training on postural balance, physical fitness, and fibromyalgia impact: pilot study of online interventionPublication . Albuquerque, Maria; Monteiro, Diogo; Alvarez, Marcos; Vilarino, Guilherme Torres; Andrade, Alexandro; Neiva, Henrique P.is a chronic disease with diverse physical and psychological symptoms and impairments. The present pilot study aims to evaluate the implementation of a previously protocoled online resistance training program in postural balance, physical fitness, and fibromyalgia impact, as well as adaptations and strategies necessary for a better followup of the participant during the program. Three participants with an average age of 53.67 (SD=5.51) years and medical diagnosis of fibromyalgia performed eight weeks of online resistance training exercises (2/week). Physical fitness and postural balance (force platform), fibromyalgia impact (FIQ), and symptoms (VAS) were evaluated before the exercises and after 16 sessions. The variation from pre- to post-training intervention was determined by calculating the percentage of change in each variable. All participants showed gains in countermovement jump (11 to 46%) and reduced pain intensity (10 to 19%). Two out of three participants showed improvement in the countermovement jump with free arms (4 and 28%), medicine ball throw (2 and 42%), mood state (20 to 32%), also a reduction in FIQ (4 and 27%), center of pressure (COP) velocity with eyes open (10 and 7%), COP displacement with eyes open (6 and 9%), anxiety (15 to 84%) and fatigue (10 to 41%). Only one participant has shown improvements in sleep quality (6%). Changes in balance with eyes closed were not found. The online resistance training program protocol showed promising results in this pilot study, with potential gains in neuromuscular performance and balance, and reducing the negative symptoms associated with fibromyalgia. Adaptations were necessary throughout the program for better applicability.
- Understanding the Associations across Fibromyalgia-Related Fatigue, Depression, Anxiety, Self-Esteem Satisfaction with Life and Physical Activity in Portuguese and Brazilian Patients: A Structural Equation Modeling AnalysisPublication . Alvarez, Marcos; Albuquerque, Maria Luiza L.; Neiva, Henrique P.; Cid, Luis; Teixeira, Diogo S.; Matos, Rui; Antunes, Raul; Lúcio, Liane; Sant’Ana, Leandro; Monteiro, DiogoBackground and Objectives: Fibromyalgia are heterogeneous and differ from patient to patient; however, the most reported are general myalgia and at specific points associated with fatigue and certain psychological adversities. Physical activity can mitigate the effects of the symptoms. However, the associations between fibromyalgia-related fatigue, self-esteem, anxiety, depression, satisfaction with life and physical activity are unclear. Therefore, the aim of the present study was to understand the associations between these symptoms and whether there are differences between these associations across two distinct cultures. Materials and Methods: A total of 473 women aged between 28 and 75 years (M = 49.27; SD ± 8.28) completed five questionnaires about fibromyalgia-related fatigue, physical activity, anxiety, depression, self-esteem, and satisfaction with life. Results: Fibromyalgia-related fatigue was positively associated with depression and anxiety, depression and anxiety were negatively associated with self-esteem, self-esteem was positively associated with satisfaction with life, satisfaction with life was positively associated with physical activity and there were no differences in terms of the perceptions and associations of these variables between Portuguese and Brazilian patients. Conclusions: Our results showed the significant role of associations between these variables and a similarity in the perception and relationship of the variables between the two cultures.
