Prevalence and predictors of unsupervised walking and physical activity in a community population of women with fibromyalgia

Exploring Biopsychosocial Stress Markers in Women With Fibromyalgia

BACKGROUND

Identification of fibromyalgia has been a challenge for healthcare professionals due to the lack of a clinical biomarker. A well-supported integrative hypothesis holds that this condition is a chronic pain problem partly caused by long-term dysregulation of stress response. Therefore, stress assessment from a biopsychosocial perspective may be a useful approach to recognizing fibromyalgia.

PURPOSE

A cross-sectional case-control study was conducted to explore stress markers from a multidimensional perspective, including heart rate variability (as a biomarker of stress) as well as psychological distress and social stress.

METHODS

Forty-seven women with fibromyalgia were recruited from support groups and another 47 were recruited as matched pain-free controls. Comparison and discriminant function analyses were performed.

RESULTS

The data support the goodness of biopsychosocial stress markers in women with fibromyalgia, resulting in the identification of between 70% and 74.5% of fibromyalgia cases (sensitivity) and 85%-87% pain-free controls (specificity), with medium-high levels of fit (λ = 0.58 and λ = 0.59; p < .00). Women with fibromyalgia were characterized by high levels of psychological distress, social stress (disorder levels), and autonomic dysregulation. Although distress and social stress had a greater weight in discriminant functions, dysregulation in terms of low parasympathetic activity and high sympathetic activity at rest was also relevant.

CONCLUSIONS

A biopsychosocial approach to stress with an objective biomarker such as heart rate variability may be a useful tool to identify and manage FM.

Promoting walking as a self-care strategy in women with fibromyalgia: a cross‑sectional study using accelerometers

INTRODUCTION

Walking is a beneficial healthy lifestyle for fibromyalgia patients as it reduces the intensity of pain and fatigue experienced and improves quality of life. In this context, self-efficacy and commitment are potential predictors of walking for women with fibromyalgia. Present study aims at examining the moderation role of exercise commitment in the association between self-efficacy for walking and walking behavior in this population.

METHOD

It is a cross‑sectional study. A total of 132 women with fibromyalgia participated (mean age = 57.63, SD = 10.44) between January and December 2018. Self-efficacy about walking was assessed through Spanish version of self-efficacy scale for physical activity scale (SEPAS) and exercise commitment through ad-hoc questionnaire (two Likert-type items about the committed action of physical activity). Walking behavior was measured using accelerometers for seven consecutive days. Pain and fatigue prior to placement of the accelerometer were evaluated as possible covariates. Regarding medical history, time since onset of symptoms (i.e. pain, fatigue) and since diagnosis, and medication were also assessed as possible covariates.

RESULTS

A moderation effect of exercise commitment was found in the relationship between self-efficacy on walking behavior (B = 10.48, p = .021, 95%, CI = 0.61 to 6.79). Post-hoc analyses showed a significant and positive relationship between self-efficacy and walking only with high commitment to physical activity (t = 10.08, p = .027, 95%, CI = 3.77 to 5.64).

CONCLUSIONS

Self-efficacy for walking and commitment should be assessed and potentially targeted when focusing on increasing walking in women with fibromyalgia. Key Points • Associations between walking self-efficacy and exercise engagement provide indications of modifiable targets for promoting an active lifestyle in fibromyalgia. • When patients feel engaged in their physical exercise pattern (walking), patients feel more able to perform the behavior. • Rehabilitation interventions, focused on chronic pain, should contemplate the promotion of self-efficacy and engagement.

Physical activity correlates in people with fibromyalgia: a systematic review

PURPOSE

Understanding the enablers of and barriers to physical activity (PA) participation in people with fibromyalgia (PwF) is an essential first step to developing effective PA interventions. This systematic review examined correlates of PA across the socio-ecological model (i.e., intra-personal, inter-personal, environmental, and policy level) in PwF.

MATERIALS AND METHODS

PubMed, Embase, and CINAHL were searched from inception until 12 July 2022. Keywords included "physical activity" or "exercise" and "fibromyalgia" or "fibrositis." Summary coding was used to quantify the PA correlates.

RESULTS

Out of 74 PA correlates retrieved from 39 articles (n = 9426), co-morbid depression and higher pain intensity were found to be consistent (i.e., reported in four or more articles) barriers to PA in PwF, while higher self-efficacy and better endurance were found to be consistent enablers to PA. Despite the abundance of evidence for the PA benefits for PwF, we only found consistent evidence for PA correlates at the intrapersonal level.

CONCLUSIONS

Health professionals should consider mental and physical health barriers when promoting PA in PwF. There remains a need to better understand social, environmental, and policy-related factors associated with PA participation in PwFImplications for rehabilitationCo-morbid depression is a notable barrier to physical activity participation in people with fibromyalgia.Experienced pain intensity should be considered as a barrier when promoting physical activity for people with fibromyalgia.Rehabilitation professionals should facilitate self-efficacy in physical activity interventions for people with fibromyalgia.Rehabilitation professionals should promote endurance when motivating people with fibromyalgia towards an active lifestyle.

Sedentary time is associated with depressive symptoms and state anxiety in women with fibromyalgia. Could physical activity and fitness modify this association? The al-Ándalus project

PURPOSE

To analyze the associations of total and prolonged sedentary time (ST) with depressive symptoms and state anxiety in women with fibromyalgia and whether these associations are modified by moderate-to-vigorous physical activity (MVPA) and physical fitness.

METHODS

This cross-sectional exploratory study included 386 women with fibromyalgia aged 51.2 ± 7.6 years. Total ST, time in prolonged bouts of ST (≥30- and ≥60-min) and MVPA were measured with triaxial accelerometry. Depressive symptoms were assessed with the "Beck Depression Inventory-second edition," state anxiety with the "State-Trait Anxiety Inventory," and physical fitness with the "Senior Fitness Test Battery."

RESULTS

Total and prolonged ST were directly associated with depressive symptoms (total: β = 0.19, ≥30-min bout: β = 0.15, and ≥60-min bout: β = 0.12) and odds of severe depressive symptoms (all, p < 0.001). These associations generally remained significant after adjustments for MVPA and physical fitness (all, p < 0.05). Total and prolonged ST were directly associated with state anxiety (total: β = 0.11, ≥30-min bout: β = 0.12, and ≥60-min bout: β = 0.07; all, p < 0.001). These associations were generally independent of MVPA (p < 0.05) but vanished when considering physical fitness (p > 0.05).

CONCLUSIONS

Higher levels of total and prolonged ST are associated with greater depressive symptoms and state anxiety in women with fibromyalgia. MVPA did not modify these associations, although physical fitness could play a protective role specially for state anxiety.IMPLICATIONS FOR REHABILITATIONReducing sedentary time and avoiding its accumulation in prolonged periods could potentially reduce depressive symptoms and state anxiety in fibromyalgia.Higher sedentary time is associated with more severe depressive symptoms even in patients who engage in moderate-to-vigorous physical activity.Higher levels of physical fitness could attenuate the negative associations of sedentary time with depressive symptoms and, specially, state anxiety."Sit less, move more and exercise to increase your fitness" could be a positive message for people with fibromyalgia in clinical settings.

Sedentary Behavior and Pain after Physical Activity in Women with Fibromyalgia-The Influence of Pain-Avoidance Goals and Catastrophizing

BACKGROUND

Fibromyalgia is characterized by chronic pain and fatigue that triggers a functional disability caused by the lack of activity. Pain catastrophizing may contribute to avoiding activity with the intention of managing pain levels. Based on the sedentary behavior with fibromyalgia, the present study assessed the preference of pain-avoidance goals and pain catastrophizing as mediator and moderator variables, respectively, that influence pain perception after a 6-min-walking test.

METHODS

The sample was composed of 76 women with fibromyalgia (mean age = 55.05, SD = 7.70). Previous sedentary behavior, preference for pain-avoidance goals, and pain catastrophizing were evaluated before starting the walking-test. Subsequently, pain perception was evaluated.

RESULTS

A significant moderated-mediation model was found in which pain-avoidance goals mediated the relationship between sedentarism and pain after a walking-test, and pain catastrophizing moderated the relationship between the preference for pain-avoidance goals and pain perception. Specifically, high levels of pain catastrophizing contributed to increased pain perceptions after completing the test (B = 0.570, p = 0.03, CI 95% (0.09, 0.11)].

CONCLUSIONS

The results suggest that motivational interventions can improve the symptoms because their objectives are focused on managing conflict goals. These interventions should focus on catastrophic cognitions considering that pain catastrophizing is deemed to be one of the major inhibitors of physical activity in fibromyalgia.

Symptoms in women with fibromyalgia after performing physical activity: the role of pain catastrophizing and disease impact

INTRODUCTION

Walking is an effective treatment for symptoms' management in patients with fibromyalgia. However, despite its benefits, fibromyalgia patients face a variety of obstacles that result in reduced ability to sustain physical exercise. The main goal of the study was to analyze the role of pain catastrophizing and fibromyalgia impact in the relationship between regular walking behavior and pain and fatigue experienced after a laboratory walking test.

METHOD

The study has an observational analytical laboratory design. A total of 100 women were contacted by the research team. Seventy-six women diagnosed with fibromyalgia aged 18 years and older (mean age = 55.05, SD = 7.69) participated.

RESULTS

Significant correlations were found among regular walking behavior, pain catastrophizing, impact of fibromyalgia, pain intensity after walking, and fatigue intensity after walking. The serial multiple mediation analyses confirmed that pain catastrophizing and impact of fibromyalgia mediated the relationship between regular walking behavior and the level of pain (beta B = 0.044, 95% CI = [0.01-0.012]) and fatigue (beta B = 0.028, 95% CI = [0.01-0.08]) after the laboratory walking test. Also, the participants that walked less regularly experienced more pain and fatigue after the 6-Minute Walk Test.

CONCLUSIONS

Considering cognitive variables alongside the impact of fibromyalgia will help understand the inhibitors of engaging in physical activity. Therapeutic walking programs must be tailored to patients with fibromyalgia to reduce pain and fatigue related to physical activity and to promote better functioning and quality of life. Key Points • Regular walking behavior was associated with fibromyalgia impact, pain catastrophizing, and less pain and fatigue after physical activity. • When patients catastrophize pain, they usually interpret physical activity as threatening, which generates more pain and fatigue after doing exercise. • Therapeutic programs should be designed to reduce pain catastrophizing and fibromyalgia impact.

Effects of Walking as Physical Exercise on Functional Limitation through Pain in Patients with Fibromyalgia-How Does Catastrophic Thinking Contribute?

Background: Aerobic exercise has a beneficial impact on physical and mental health. However, patients with fibromyalgia do not always report perceiving these improvements. Objective: The aim of this study was to examine whether catastrophic thinking moderated the effects of perceived pain severity once an active and regular lifestyle had been established on functional limitation in chronic pain patients, in particular in fibromyalgia patients. Methods: The sample consisted of a total of 491 women with fibromyalgia diagnosed according to the criteria of the American College of Rheumatology. Participants completed an ad-hoc item about lifestyle related to walking pattern, the Brief Pain Inventory, the Pain Catastrophization Scale, and the Fibromyalgia Impact Questionnaire-Revised. To examine the relationship between the variables, a moderate mediation analysis was performed through the macro PROCESS (model 14). Results: The relationship between the performance of the recommended walking pattern and functional limitation was mediated by the severity of pain (B = −5.19, SE = 1.59, t = −3.25, 95% CI = [−4.06, −0.28], p < 0.001). Furthermore, it was found that the mediating effect of pain severity was moderated by catastrophic thinking (Index = −0.014, SE = 0.007, 95% CI [0.002, 0.030]). Conclusions: The positive effect of walking on functionality through the reduction of pain levels is favored when patients present low catastrophizing, which affects the relevance of including interventions focused on the reduction of catastrophizing in the prescription of physical exercise in patients with fibromyalgia as the treatment of choice.

Predicting Adherence to Walking from Anxiety, Depression, Disease Impact, Catastrophizing, and Cognitive Fusion in Patients with Fibromyalgia: Does Pain Severity Matter?

AIM

This study analyzed whether the contribution of several factors associated with walking adherence in fibromyalgia (FM) patients varies across pain severity levels.

METHODS

Participants were 228 women with FM (mean age 57 years; SD = 8.49).

RESULTS

Bivariate analyses replicated the expected association between predictors (FM impact, anxiety, depression, catastrophizing, and cognitive fusion) and poorer adherence to walking. Multivariate analyses showed a negative contribution of FM impact, catastrophizing, and depression on walking adherence after controlling for pain levels (all p < 0.01). A moderation effect of pain severity in the relationship between predictors and adherence to walking was only found for cognitive fusion (B = -0.01, t = -2.02, p = 0.040). Specifically, cognitive fusion only contributed to poor walking adherence at moderate and severe pain levels, but not when pain was mild. The contribution of the remaining predictors was not moderated by pain levels, which means that they contributed to walking adherence irrespective of the pain severity of the patient. Pain severity did not contribute to walking adherence when controlling for the predictors.

CONCLUSION

Clinical implications are discussed from the perspective of personalized interventions and preferable target interventions when attempting to increase adherence to walking in this population.

Exploring the Relationship between Fibromyalgia-Related Fatigue, Physical Activity, and Quality of Life

The 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.

The Role of Walking in the Relationship between Catastrophizing and Fatigue in Women with Fibromyalgia

Walking is one of the most beneficial treatments for fibromyalgia patients. However, adherence to walking behavior is low due to the initially associated symptoms (including pain and fatigue). Although the association of catastrophism with greater symptoms is known, the results regarding fatigue have not always been consistent. Nevertheless, it is unknown whether the association between catastrophism and fatigue could, in turn, be conditioned by whether the patients walk or not. Therefore, our goal was to explore the moderating effect of walking on the association between catastrophizing and fatigue in patients with fibromyalgia. A cross-sectional study was carried out with 203 women with fibromyalgia. We used the Multidimensional Fatigue Inventory to assess fatigue and the Pain Catastrophizing Scale to assess pain catastrophizing (differentiating between its three dimensions). An ad hoc item was used to evaluate walking (moderator). Lower scores for fatigue and pain catastrophizing were found among patients who walked versus those who did not. Walking moderated the relationship between rumination and fatigue (Beta = 0.16, t = 1.96, p = 0.049) and between magnification and fatigue (Beta = 0.22, t = 21.83, p = 0.047). Helplessness showed no direct or interaction effect for fatigue. Nevertheless, higher rumination and magnification were associated with higher fatigue only in patients who walked. Therefore, to promote adherence to walking and reduce the effects of catastrophizing on fatigue, it seems necessary to manage rumination and magnification among patients who walk.

Assessing Walking Programs in Fibromyalgia: A Concordance Study between Measures

This study analyzes the degree of agreement between three self-report measures (Walking Behavior, WALK questionnaire and logbooks) assessing adherence to walking programs through reporting their components (minutes, rests, times a week, consecutive weeks) and their concordance with a standard self-report of physical activity (IPAQ-S questionnaire) and an objective, namely number of steps (pedometer), in 275 women with fibromyalgia. Regularized partial correlation networks were selected as the analytic framework. Three network models based on two different times of assessment, namely T1 and T2, including 6 weeks between both, were used. WALK and the logbook were connected with Walking Behavior and also with the IPAQ-S. The logbook was associated with the pedometers (Z-score > 1 in absolute value). When the behavior was assessed specifically and in a detailed manner, participants’ results for the different self-report measures were in agreement. Specific self-report methods provide detailed information that is consistent with validated self-report measures (IPAQ-S) and objective measures (pedometers). The self-report measures that assess the behavioral components of physical activity are useful when studying the implementation of walking as physical exercise.

Pain-Related Worrying and Goal Preferences Determine Walking Persistence in Women with Fibromyalgia

Physical activity and exercise are relevant behaviors for fibromyalgia health outcomes; however, patients have difficulties undertaking and maintaining an active lifestyle. With a cross-sectional design, this study explored the role of pain-related worrying and goal preferences in the walking persistence of women with fibromyalgia. The sample included 111 women who attended a tertiary health setting. We adapted the Six-Minute Walk Test where participants decided either to stop or continue walking in five voluntary 6 min bouts. Women who were categorized higher in pain-related worrying reported higher preference for pain avoidance goals (t = -2.44, p = 0.02) and performed worse in the walking task (LongRank = 4.21; p = 0.04). Pain avoidance goal preference increased the likelihood of stopping after the first (OR = 1.443), second (OR = 1.493), and third (OR = 1.540) 6 min walking bout, and the risk of ending the walking activity during the 30 min task (HR = 1.02, [1.0-1.03]). Influence of pain-related worrying on total walking distance was mediated by goal preferences (ab = -3.25). In interventions targeting adherence in physical activity and exercise, special attention is needed for women who are particularly worried about pain to help decrease their preference for short-term pain avoidance goals relative to long-term goals such as being active through walking.

Exploring the Preference for Fatigue-avoidance Goals as a Mediator Between Pain Catastrophizing, Functional Impairment, and Walking Behavior in Women With Fibromyalgia

OBJECTIVES

Along with the symptoms of pain and fatigue, pain catastrophizing and avoidance behaviors are highly prevalent and associated with functional impairment in fibromyalgia (FM) patients. Although pain and fatigue affect patients' quality of life, research has been exclusively focused on how pain affects physical activity and exercise. The aim of this study was to analyze the role of pain catastrophizing and preference for fatigue-avoidance goals in walking behavior and functional impairment in women with FM.

MATERIALS AND METHODS

In this cross-sectional study the sample was composed of 76 participants aged 18 years and older (mean age=55.05, SD=7.70). The study evaluated pain catastrophizing, preference for fatigue-avoidance goals, functional impairment, and walking behavior along with sociodemographic variables and clinical data.

RESULTS

Pain catastrophizing was associated with preference for fatigue-avoidance goals and this preference was associated with greater functional impairment and less distance walked. Path analysis supported the mediating role of preference for fatigue-avoidance goals in the relationship between pain catastrophizing and walking behavior and between pain catastrophizing and functional impairment. Furthermore, pain catastrophizing predicted greater preference for fatigue-avoidance goals which predicted more problems in functioning and less distance walked.

DISCUSSION

The present study may help clarify the connection between the factors that stop individuals with FM from implementing beneficial behaviors such as walking, and thus, allowing for the design of psychological interventions that seek to maintain physical functioning despite experiencing fatigue.

Do Cognitive Abilities Influence Physical and Mental Fatigue in Patients with Chronic Pain after Walking According to a Clinical Guideline for Physical Exercise?

The objective of this study is to explore the mediator role of cognitive fusion and chronic pain acceptance on the effects that the walking pattern, following an established clinical guideline for physical exercise, can have on fatigue (physical and mental) in patients with chronic pain. The sample consisted of a total of 231 women with fibromyalgia with a mean age of 56.91 years (Standard Deviation SD = 9.58 years, range 30−78 years). The results show a significant indirect effect of the walking pattern on both physical and mental fatigue through cognitive fusion and chronic pain acceptance. Specifically, walking predicted less cognitive fusion, which predicted greater chronic pain acceptance, which, in turn, predicted less mental and physical fatigue (Beta-B- = −0.04, Standard Error SE = 0.02, 95% Confidence Interval 95% CI = [−0.09, −0.02]; B = −0.09, SE = 0.05, 95% CI = [−0.22, −0,15], respectively). It can be concluded that the walking pattern is linked to both physical and mental fatigue through cognitive defusion and chronic pain acceptance. These cognitive abilities would allow fibromyalgia patients to perceive an improvement in both physical and mental fatigue by carrying out the walking pattern. Emphasizing the training of cognitive defusion and pain acceptance would improve the adherence of these patients to walking.

Motivational Determinants of Objective Physical Activity in Women with Fibromyalgia Who Attended Rehabilitation Settings

Being physically active has positive effects on fibromyalgia functioning. However, promoting an active lifestyle in these patients continues to be a relevant clinical challenge. Our aim was to test a motivational model to explain light (LPA) and moderate-vigorous physical activity (MVPA). A cross-sectional prospective study was conducted at a tertiary level of care. Participants completed sociodemographic, clinical, motivational (physical activity self-efficacy and goal preferences) and behavioral measures (activity avoidance). LPA and MVPA were measured with triaxial accelerometers, starting the same day of the aforementioned assessment. Out of 211 women, 183 completed this measure. Structural models were performed. Our results show that the best fit indices (CFI = 0.97, SRMR = 0.04) showed a model with direct influence of PA self-efficacy on MVPA (p < 0.01) and indirect influence on LPA (p < 0.001). LPA received the influence of PA self-efficacy mainly through activity avoidance (p < 0.01). Clinical variables did not have any effect on PA intensities. Thus, the motivational variables showed different paths to explain two PA intensities. Targeting PA self-efficacy in rehabilitation settings is needed to enhance both daily LPA and MVPA intensities.

Fibromyalgia in social media: content and quality of the information analysis of videos on the YouTube platform

To evaluate the fibromyalgia (FM) content in YouTube videos and verify if American College of Rheumatology (ACR) guidelines are being met. The videos were searched with the keyword "Fibromyalgia." Two independent researchers evaluated and coded specific characteristics of the videos. The popularity of the videos, the presentation properties, and content related to FM according to the ACR criteria were analyzed. Of the 200 videos included, the majority were presented by health professionals, 61.5%. Most videos covered more than one subject, 38.5%. The videos presented by health professionals were the most viewed. Following the ACR guidelines, 38% defined FM, 24% described the etiology, 19.5% described the diagnostic criteria and 52% presented recommended management strategies. The results indicate that users mainly watch videos published by health professionals. Most of the published videos do not follow the information recommended by the ACR guidelines. Therefore, videos should be interpreted with caution, not being the most appropriate resource for health education for patients with FM. Most of the videos published on YouTube about FM do not meet the ACR guidelines for FM.

Assessing Self-Efficacy for Physical Activity and Walking Exercise in Women with Fibromyalgia

BACKGROUND

Exercise and physical activity are an evidence-based practice for chronic pain. Health professionals need instruments to assess self-efficacy for this practice taking into account the specific barriers of patients with these health problems.

PURPOSE

To develop and test the psychometric properties of a new self-efficacy scale for physical activity and walking exercise in patients with fibromyalgia.

DESIGN

A cross-sectional and prospective study was conducted in a Spanish Fibromyalgia Unit. Two hundred and eleven new patients signed the informed consent and participated in the study. All of them were women, referred to by either Primary or Specialized Health Care. In addition to the new scale, they filled out several self-reported and validated instruments to collect the data present in this study.

RESULTS

Exploratory factor analysis showed a three-factor model (GFI = .99; RMSR = .06) that explained 74.2% of the total variance. They assessed how confident patients felt about walking quickly in both 30- and 60-minute sessions, (Factor I: 10 items; α = .97), to perform daily physical activities (Factor II: 10 items; α = .93) and to undertake moderate physical activity (Factor III: 5 items; α = .95). The total score of the scale and the three-factor scores showed good criterion validity and adequate validity based on the relationships with other constructs.

CONCLUSIONS

The scale showed adequate psychometric properties and can be a useful tool to help health professionals monitor patients' self-efficacy perception and customize both physical activity and walking exercise intervention goals and their implementation.

Is active commuting associated with sedentary behaviour and physical activity in women with fibromyalgia? The al-Ándalus project

PURPOSE

This study aimed to examine the association between active commuting and sedentary time (ST) and physical activity (PA) in women with fibromyalgia.

MATERIALS AND METHODS

This cross-sectional study included 420 women with fibromyalgia (aged 30 to 74 years old) from Spain. The participants wore an accelerometer during seven days to record ST and PA. They also self-reported patterns of active commuting. Linear regression analyses were conducted to examine the relationships between commuting and accelerometer outcomes. Age, pressure pain threshold, and accelerometer wear time were used as confounders.

RESULTS

There was a negative association between active commuting and ST whereas active commuting was positively associated with moderate PA, moderate-to-vigorous PA, total PA, and step count (all p ≤ 0.01). No associations were observed in the older group.

CONCLUSION

Younger women with fibromyalgia who were active commuters spent less ST and were involved in greater PA than passive commuters. This study highlights the importance of promoting active commuting to increase PA among young women with fibromyalgia, while other sources of PA might be recommended for older patients if levels of active commuting are not increased.Implications for rehabilitationActive commuting is a source to increase PA in women with fibromyalgia.Active commuting alone does not seem to be enough to increase PA levels in older women with fibromyalgia and additional PA strategies should be implemented.Promotion of active commuting in young women with fibromyalgia is recommended.

Why do some people with severe chronic pain adhere to walking prescriptions whilst others won't? A cross-sectional study exploring clinical and psychosocial predictors in women with fibromyalgia

Fibromyalgia (FM) is a highly disabling condition characterized by widespread chronic pain. Physical exercise, such as walking, has been recommended as the treatment of choice for FM. However, adherence to physical exercise tends to be poor. Pain is one of the main inhibitors to adhere to walking in FM patients. The main objective of this study has been to determine whether there is a clinical and psychosocial profile to help predict individual differences in adherence to walking in a sample of patients with FM with severe pain levels. In this cross-sectional study, the sample was composed of 172 women with FM and severe pain levels (> 7 in an 11-point numerical scale). Women were classified into two groups: (1) those who walked regularly and (2) patients who rarely or never walked. Group differences regarding clinical outcomes (e.g., FM impact, anxiety, depression, cognitive fusion, catastrophizing, affect, and personality), sociodemographic variables, and medical history were analyzed. Patients who walked despite pain significantly reported less impact of FM, anxiety, depression, catastrophizing, cognitive fusion, negative affect, openness to experience, agreeableness, and conscientiousness. The unique predictors of group membership (walking versus no walking) in a binary regression were FM impact and negative affect. The results show that adherence to exercise might be influenced and predicted by the clinical profile of the patient, which suggests that personalized motivational interventions should be addressed to this at-risk subgroup.

The 4 U's Rule of Fibromyalgia: A Proposed Model for Fatigue in a Sample of Women with Fibromyalgia: A Qualitative Study

Although fatigue usually goes unnoticed, it is a symptom that poses great challenges to patients with fibromyalgia and is a strong limitation. The aim of this study is to identify and describe the variables involved in fatigue in nine different situations of the Goal Pursuit Questionnaire (GPQ) that may occur in the daily lives of women with fibromyalgia, according to an ABC (Antecedents–Behaviors–Consequences) model. This study followed a qualitative descriptive research method and a deductive–inductive hybrid approach based on a phenomenological paradigm. Twenty-six women with fibromyalgia participated in focus group discussions between February and March of 2018. Thematic content analysis was carried out from transcribed verbatim interviews. We identified nine major themes that emerged from the participants’ conversations: self-imposed duties, muscle fatigue, overwhelming feeling of tiredness, difficulty thinking, difficulty concentrating, negative emotions, lifestyle changes, affected everyday activities, and lack of motivation for daily activities and social interactions. We conclude that the ABC model allowed certain elements to emerge regarding the fatigue experience, highlighting its importance as a symptom in fibromyalgia. This additional analysis of the ABC model showed that fatigue can be described through the 4 U’s Rule, which is integrated by these four adjectives: (1) Unpredictable, (2) Uncontrollable, (3) Unseen, and (4) Unintelligible. Identifying these characteristics can contribute to a better understanding of fibromyalgia in addition to better treatment for these patients.

Promoting unsupervised walking in women with fibromyalgia: a randomized controlled trial

The objective of this study is to test the efficacy of a group motivational plus implementation intentions intervention in promoting adherence to an unsupervised walking program recommended for fibromyalgia, compared to an implementation intentions condition and to an active control condition. A triple-blind, randomized, longitudinal study with measures at baseline, short (seven weeks post-intervention), mid (12 weeks) and long-term (36 weeks) is performed. Data are analyzed using multilevel longitudinal growth curve two-level modelling. Participants are 157 women with fibromyalgia. In the short-term, adherence to the minimum and to the standard walking program (primary outcome measures) is explained by time (both p <.001), motivational plus implementation intentions intervention (both p <.001) and by their interaction (both p <.001). Regarding the secondary outcomes, only physical function is explained by time (p <.001), motivational plus implementation intentions intervention (p <.05) and by their interaction (p <.05). Motivational plus implementation intentions intervention achieve the promotion of walking as an exercise in the short-term; furthermore, physical function of the women in this condition is better than in the other two intervention groups, which is a relevant outcome from a rehabilitation point of view. However, more studies are needed to maintain the exercise at mid and long-term.

Goal Preferences, Affect, Activity Patterns and Health Outcomes in Women With Fibromyalgia

Some motivational models understand health behavior as a result of the interaction between goal preferences and mood. However, this perspective has not been explored in fibromyalgia. Furthermore, in chronic pain, it has only been explored with regard to negative affect. Thus, our aims were: (1) to develop a Spanish version of the Goal Pursuit Questionnaire (GPQ); (2) to explore the relationships between goal preferences and health outcomes, testing the moderator role of affect and the mediating role of chronic pain activity patterns. We conducted two cross-sectional studies. In Study 1, after a double translation/back-translation process, we interviewed 94 women attending the Fibromyalgia Unit of the Community of Valencia in order to identify the cultural feasibility and the content validity of the GPQ. Study 2 comprised 260 women. We explored the GPQ structure and performed path analyses to test conditional mediation relationships. Eight activities from the original GPQ were changed while maintaining the conceptual equivalence. Exploratory factor analysis showed two factors: 'Pain-avoidance goal' and 'Mood-management goal' (37 and 13% of explained variance, respectively). These factors refer to patients' preference for hedonic goals (pain avoidance or mood-management) over achievement goals. Robust RMSEA fit index of the final models ranged from 0.039 for pain to 0.000 for disability and fibromyalgia impact. Pain avoidance goals and negative affect influenced pain mediated by task-contingent persistence. They also affected disability mediated by task and excessive persistence. Pain avoidance goals and positive affect influenced fibromyalgia impact mediated by activity avoidance. We also found a direct effect of negative and positive affect on health outcomes. Preference for pain avoidance goals was always related to pain, disability and fibromyalgia impact through activity patterns. Affect did not moderate these relationships and showed direct and indirect paths on health outcomes, mainly by increasing persistence and showing positive affect as an asset and not a risk factor. Intervention targets should include flexible reinforcement of achievement goals relative to pain avoidance goals and positive affect in order to promote task-persistence adaptive activity patterns and decreased activity avoidance.

Substituting Sedentary Time With Physical Activity in Fibromyalgia and the Association With Quality of Life and Impact of the Disease: The al-Ándalus Project

OBJECTIVE

There is an overall awareness of the detrimental health effects of sedentary time (ST) in fibromyalgia; however, data are limited on how replacement of ST with physical activity (PA) of different intensity may be related to health in this condition. The aim of this study was to examine how a substitution of ST with light PA (LPA) or moderate-to-vigorous PA (MVPA) is associated with quality of life and disease impact.

METHODS

This study comprised 407 women with fibromyalgia, mean ± SD age 51.4 ± 7.6 years. The time spent in ST and PA was measured with triaxial accelerometry. Quality of life and disease impact were assessed using the Short Form 36 (SF-36) health survey and the Revised Fibromyalgia Impact Questionnaire (FIQR), respectively. The substitution of ST with an equivalent time of LPA or MVPA and the associated outcomes were examined using isotemporal substitution analyses.

RESULTS

Substituting 30 minutes of ST with LPA in the isotemporal model was associated with better scores in bodily pain (B = 0.55), vitality (B = 0.74), and social functioning (B = 1.45) according to the SF-36, and better scores at all of the domains (function, overall impact, symptoms, and total impact) of the FIQR (B ranging from -0.95 to -0.27; all P < 0.05). When ST was replaced with MVPA, better physical role (B = 2.30) and social functioning (B = 4.11) of the SF-36 and function of the FIQR (B = -0.73) were observed (all P < 0.05).

CONCLUSION

In regression models, allocation of time of sedentary behavior to either LPA or MVPA was associated with better quality of life and lower disease impact in women with fibromyalgia.

Healthcare Provider Advice to Engage in Walking Regimens and Adherence in Women With Fibromyalgia

PURPOSE

The aim of the study was to analyze the profile of fibromyalgia patients receiving medical advice to walk and who complied with the advice according to a specific clinical pattern. A further aim has been to analyze the elements that increase adherence to walking.

DESIGN

A cross-sectional study with 920 women with fibromyalgia.

METHODS

Sociodemographic and clinical variables, walking behavior, and medical advice to walk were assessed.

FINDINGS AND CONCLUSIONS

Patients who adhere to walking have a lower likelihood of being tired. Regular walkers (patients who walk according to a specific clinical pattern) have a lower likelihood of comorbidity. Patients who receive medical advice to walk are more likely to walk more than 30 minutes and to take a break between bouts.

CLINICAL RELEVANCE

Nurses caring for people with fibromyalgia should include strategies to promote walking, especially in patients with low adherence profiles, paying attention to all elements of behavior.

The influence of balance, physical disability, strength, mechanosensitivity and spinal mobility on physical activity at home, work and leisure time in women with fibromyalgia

BACKGROUND

Fibromyalgia syndrome is a chronic disease consisting of widespread pain, fatigue, sleep disturbances, and cognitive impairments, among other symptoms, which affect daily physical activity. However, the influence of functional status on physical activity involved in leisure, household and work activities has not been researched previously. The main objective was to evaluate balance, strength, spinal mobility, mechanosensitivity and function levels as related factors of physical activity in female with fibromyalgia.

METHODS

Thirty-four patients with Fibromyalgia and 22 matched controls were included in a cross-sectional study. Dynamic and static balance, general and daily activities disability, lumbosacral mechanosensitivity, spinal range of motion, lower limb strength, physical activity in leisure, household and work activities were registered. We tested for differences between groups by using independent sample t-tests. The influence of demographics, symptoms and physical outcomes on physical activity was statistically analyzed using bivariate and multivariate regression analyses.

FINDINGS

There was a significant association between leisure-time physical activity scores and age (r = 0.564), spinal flexion (r = 0.512), spinal extension (r = 0.421) and the total range of spinal inclination (r = 0.533). Fifty-eight percent of the variance of leisure-time physical activity was explained by age and range of spinal flexion-extension. Similarly, functional mobility was associated with physical activity at home and work scores (r = 0.459), explaining 21% of its variance.

INTERPRETATION

A higher time spent in leisure, household and work activities was related to higher age, spinal range of motion and lower functional mobility in women with Fibromyalgia. Rehabilitation intervention programs should promote physical activity at home, work and leisure time.

Dissociative features of fibromyalgia syndrome

Objective:

To assess the relationships between the dissociative features of FMS and the pain, psychological status, and functional status.

Methods:

Twenty-seven women with fibromyalgia syndrome (FMS) and 24 controls from the Istanbul Physical Medicine and Rehabilitation Hospital (2013-2015) were included in this cross-sectional study. The Diagnostic and Statistical Manual of Mental Disorders Structured Clinical Interview for Axis I Disorders was used to evaluate the participants. A visual analogous scale (VAS), Fibromyalgia Impact Questionnaire (FIQ), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) were used to assess the levels of pain, quality of sleep and functional and psychological statuses. The Dissociative Experiences Scale (DES) was used to evaluate the dissociative features.

Results:

The BDI, BAI and DES scores were statistically significantly higher in the cases of FMS. There were remarkable associations between all but 2 of the DES and FIQ scores, while positive correlations were found between the DES and, VAS pain and sleep quality scores. The prevalences of current and lifelong dysthymia, and major depressive disorder; not otherwise specified, common anxiety and somatoform disorders were higher in the cases of FMS.

Conclusion:

Pain, physical function and emotional status appear to be associated with dissociative features in FMS. Further studies are required to define these relationships and improve treatment.
