Catastrophizing, Kinesiophobia, and Acceptance as Mediators of the Relationship Between Perceived Pain Severity, Self-Reported and Performance-Based Physical Function in Women with Fibromyalgia and Obesity

Purpose

Individuals with fibromyalgia and obesity experience significant impairment in physical functioning. Pain catastrophizing, kinesiophobia, and pain acceptance have all been identified as important factors associated with the level of disability. The objective of this study was to evaluate the role of pain catastrophizing, kinesiophobia, and pain acceptance as mediators of the association between perceived pain severity and physical functioning in individuals with fibromyalgia and obesity.

Patients and Methods

In this cross-sectional study, 165 women with fibromyalgia and obesity completed self-report questionnaires of perceived pain severity (ie, Numeric Pain Rating Scale), pain catastrophizing (ie, Pain Catastrophizing Scale), kinesiophobia (ie Tampa Scale of Kinesiophobia), pain acceptance (ie, Chronic Pain Acceptance Questionnaire), and perceived physical functioning (ie, Physical Functioning subscale of the Fibromyalgia Impact Questionnaire). In addition, a performance-based test (ie, 6-minute walking test) was conducted to assess objective physical functioning. Two multiple mediation analyses were performed.

Results

Pain acceptance and kinesiophobia mediated the relationship between pain severity and self-reported physical functioning. Pain catastrophizing and kinesiophobia mediated the relationship between pain severity and performance-based functioning.

Conclusion

Pain acceptance, kinesiophobia, and pain catastrophizing should be addressed in rehabilitative intervention to improve physical functioning. Interestingly, the subjective and objective aspects of physical functioning are influenced by different factors. Therefore, interventions for women with fibromyalgia and obesity should focus on factors related to both subjective and performance-based physical functioning.

Individuals with fibromyalgia have a different gait pattern and a reduced walk functional capacity: a systematic review with meta-analysis

Background

The aim of the present study was to perform a systematic review and meta-analysis comparing walking test performance and gait pattern between individuals with and without fibromyalgia (FM).

Methodology

This systematic review was registered in PROSPERO with the following reference: CRD42018116200.The search for the scientific articles in this systematic review was carried out using the MEDLINE, SCOPUS, PEDRO, CINHAL and WEB OF SCIENCE databases. A combination of three conceptual groups of terms was used: (1) fibromyalgia; (2) walk (performance) tests; and (3) gait analysis. The included articles were analyzed for both functional and pattern of walking data of patients with FM. In order to provide a better estimate of the difference between individuals with and without FM on gait, a meta-analysis was performed on the 6MWT (6-minute walk test).

Results

Thirty-six studies were analyzed, with a total population of 4.078 participants (3.369 FM and 709 individuals without FM). From a functional point of view, the 6MWT distance covered by the group of individuals without FM was significantly greater than that of the individuals with FM in all the analyzed studies. In addition, when comparing the results obtained in the gait pattern analysis, it was observed that individuals with FM walked slower, with a shorter stride length and lower cadence compare to individuals without FM.

Conclusions

It is possible to affirm that individuals with FM perform walking tests differently than individuals without FM. It was observed that individuals with FM walk performing a cycle of shorter length and lower frequency, producing a slower gait, which results in a shorter distance traveled, in the same period of time, with respect to healthy subjects.

The Role of Pain Catastrophizing and Pain Acceptance in Performance-Based and Self-Reported Physical Functioning in Individuals with Fibromyalgia and Obesity

Impaired physical functioning is one of the most critical consequences associated with fibromyalgia, especially when there is comorbid obesity. Psychological factors are known to contribute to perceived (i.e., subjective) physical functioning. However, physical function is a multidimensional concept encompassing both subjective and objective functioning. The contribution of psychological factors to performance-based (i.e., objective) functioning is unclear. This study aims to investigate the contribution of pain catastrophizing and pain acceptance to both self-reported and performance-based physical functioning. In this cross-sectional study, 160 participants completed self-report measures of pain catastrophizing, pain acceptance, and pain severity. A self-report measure and a performance-based test were used to assess physical functioning. Higher pain catastrophizing and lower pain acceptance were associated with poorer physical functioning at both self-reported and performance-based levels. Our results are consistent with previous evidence on the association between pain catastrophizing and pain acceptance with self-reported physical functioning. This study contributes to the current literature by providing novel insights into the role of psychological factors in performance-based physical functioning. Multidisciplinary interventions that address pain catastrophizing and pain acceptance are recommended and might be effective to improve both perceived and performance-based functioning in women with FM and obesity.

Functional status, physical activity level, and exercise regularity in patients with fibromyalgia after Multidisciplinary treatment: retrospective analysis of a randomized controlled trial

Multidisciplinary treatments have shown to be effective for fibromyalgia. We report detailed functional outcomes of patients with fibromyalgia who attended a 3-month Multidisciplinary treatment program. The hypothesis was that patients would have increased functional status, physical activity level, and exercise regularity after attending this program. We performed a retrospective analysis of a randomized, simple blinded clinical trial. The inclusion criteria consisted of female sex, a diagnosis of fibromyalgia, age 18-60  and 3-8 years of schooling. Measures from the Fibromyalgia Impact Questionnaire (FIQ) and the COOP/WONCA Functional Health Assessment Charts (WONCA) were obtained before and at the end of the treatment and at 3-, 6-, and 12-month follow-ups. Patients recorded their number of steps per day with pedometers. They performed the six-minute walk test (6 MW) before and after treatment. In total, 155 women participated in the study. Their median (interquartile interval) FIQ score was 68.0 (53.0-77.0) at the beginning of the treatment, and the difference between the Multidisciplinary and Control groups was statistically and clinically significant in all of the measures (except the 6-month follow-up). The WONCA charts showed significant clinical improvements in the Multidisciplinary group, with physical fitness in the normal range across almost all values. In that group, steps/day showed more regularity, and the 6 MW results showed improvement of -33.00 (-59.8 to -8.25) m, and the differences from the Control group were statistically significant. The patients who underwent the Multidisciplinary treatment had improved functional status, physical activity level, and exercise regularity. The functional improvements were maintained 1 year after treatment completion.

Spatio-temporal gait disorder and gait fatigue index in a six-minute walk test in women with fibromyalgia

BACKGROUND

Gait disorders in fibromyalgia patients affect several gait parameters and different muscle recruitment patterns. The aim of this study was to assess the gait differences observed during a six-minute walk test between fibromyalgia patients and healthy controls.

METHODS

Forty-eight women with fibromyalgia and 15 healthy women were evaluated. Fibromyalgia patients met the American College of Rheumatology criteria for fibromyalgia selected of an ambulatory care. Both patients and controls had a negative history of musculoskeletal disease, neurological disorders, and gait abnormalities. The 15 controls were healthy women matched to the patients in age, height and body weight. Spatio-temporal gait variables and the rate of perceived exertion during the six-minute walk test (all subjects) and Fibromyalgia Impact Questionnaire (fibromyalgia subjects) were evaluated. All walking sets on the GaitRITE were collected and the gait variables were selected at three stages during the six-minute walk test: two sets at the beginning, two sets at 3 min and two sets at the end of the test. In addition, the Fibromyalgia Impact Questionnaire was used for the fibromyalgia patients.

FINDINGS

Fibromyalgia patients showed a significant decrease in all spatio-temporal gait variables at each of the three stages and had a lower walk distance covered in the six-minute walk test and higher rate of perceived exertion. No correlations were found between the Fibromyalgia Impact Questionnaire and gait variables. The fibromyalgia and control subjects showed lower gait fatigue indices between the middle and last stages.

INTERPRETATION

Gait analysis during a six-minute walk test is a good tool to assess the fatigue and physical symptoms of patients with fibromyalgia.

[Sport and rheumatoid arthritis]

BACKGROUND

Sport is becoming increasingly more important in our society. Due to the changing age spectrum with a greater number of elderly and substantially more active people, an increasing number of people with underlying orthopedic diseases are becoming interested in participating in sport.

MATERIAL AND METHODS

This article deals with the possibilities and effects of sporting activities for people with rheumatoid arthritis within the framework of a conservative therapy. A literature search was carried out using medical search engines, in particular PubMed, and also via the recommendations of specialist societies and patient help groups.

RESULTS

The quality of life of patients with rheumatoid arthritis consists of physical, mental and social components. Sport as a means of rehabilitation influences all of these components. Sport should be comprehended as a form of therapy and be adapted to the needs of the individual patient. The willingness to actively participate in sport should always be highly rated and encouraged. Sport is therefore an important pillar of therapy in a conservative total concept. The main aspects of sport therapeutic activities are functional, pedagogical and experience-oriented aspects. The clinical symptoms, extent of damage and physical impairment must, however, be evaluated and taken into consideration for the therapeutic concept.

CONCLUSION

The amount of data on the complex topic of sport and rheumatoid arthritis is low and is mainly dealt with as retrospective reviews. A prospective randomized study basis is lacking. The aim must therefore be to confirm the currently available recommendations for various types of sport in controlled studies.

Independent and combined association of overall physical fitness and subjective well-being with fibromyalgia severity: the al-Ándalus project

PURPOSE

The present study aimed: (1) to test the associations of overall physical fitness and subjective well-being with fibromyalgia severity and (2) to determine whether the combination of overall physical fitness and subjective well-being is associated with fibromyalgia severity among adult women patients.

METHODS

This cross-sectional study included 424 participants from Andalusia, southern Spain. Overall physical fitness and the components of subjective well-being (positive affect, negative affect and cognitive well-being), and fibromyalgia severity were assessed using the Functional Senior Physical Fitness Test Battery, the Positive and Negative Affect Schedule, the Satisfaction With Life Scale, and the Fibromyalgia Impact Questionnaire, respectively.

RESULTS

Overall physical fitness (β = -.23), positive affect (β = -.18), negative affect (β = .26), and cognitive well-being (β = -.18) were all associated with fibromyalgia severity. The patients with the highest overall physical fitness and increased subjective well-being reported ~15 % lower fibromyalgia severity than those with the lowest fitness and poorest subjective well-being (Cohen's d > 1.0).

CONCLUSION

Our results suggest that higher levels of overall physical fitness and subjective well-being are independently associated with lower fibromyalgia severity. Moreover, patients with higher overall physical fitness and increased subjective well-being (high positive affect, low negative affect, or high cognitive well-being) reported lower fibromyalgia severity than those with low levels of overall physical fitness and subjective well-being.

Análise das capacidades físicas de mulheres com fibromialgia segundo o nível de gravidade da enfermidade

A fibromialgia (FM) é uma síndrome crônica que se caracteriza por dor musculoesquelética generalizada, que provoca acentuada redução na capacidade física dos pacientes afetando a sua saúde e qualidade de vida. OBJETIVO: Avaliar a capacidade física dos pacientes com FM relacionada com a gravidade da enfermidade. MÉTODO: Estudo descritivo transversal sobre uma amostra de 66 mulheres com FM (idade: 51,79 ± 8,02 anos) e um grupo de controle de mulheres saudáveis (idade 50,26 ± 8,75 anos). Analisou-se a amplitude física mediante bateria de provas físicas específicas com aplicação de questionários: Fibromyalgia Impact Questionnaire (FIQ) e o Short-Form Healthy Survey (SF-36), na versão espanhola. RESULTADOS: As mulheres saudáveis apresentam os valores de amplitude física superiores aos das mulheres enfermas com (p < 0,05) exceto na prova de dinamometria manual. Exclusivamente na prova de agilidade se pôde discriminar os pacientes de FM segundo a gravidade da enfermidade (p = 0,021). A qualidade de vida nos pacientes com FM se encontra muito deteriorada em comparação (p = 0,021) com as mulheres saudáveis e os valores que normatizam a sociedade espanhola. CONCLUSÕES: A análise das capacidades físicas é um elemento de relevância clínica na avaliação complementar da fibromialgia.

Pain and functional capacity in female fibromyalgia patients

OBJECTIVE

To examine the association between pain and functional capacity levels.

DESIGN

[corrected] Cross-sectional study.

SETTING

University of Granada.

SUBJECTS

One hundred twenty-three women with fibromyalgia (51.7 ± 7.2 years).

OUTCOME MEASURES

We measured weight and height, and body mass index (BMI) was calculated. We assessed tender points by pressure pain and functional capacity by means of the 30-second chair stand, handgrip strength, chair sit and reach, back scratch, blind flamingo, 8-ft up and go and 6-minute walk tests.

RESULTS

We observed an association of tender points count with the chair stand and 6-minute walk tests (r = -0.273, P = 0.004 and r = -0.183, P = 0.046, respectively). These associations became nonsignificant once the analyses were adjusted by weight or BMI. We observed an association of algometer score with the back scratch, chair stand, and 6-minute walk tests (r = 0.238, P = 0.009; r = 0.363, P < 0.001; and r = 0.186, P = 0.043, respectively), which remained after adjusting for weight or BMI, except the association between algometer score and the 6-minute walk test that became nonsignificant once the analyses were adjusted by weight. Prevalence of overweight and obesity was 39.2 and 33.3%, respectively.

CONCLUSIONS

There is an inverse association of tender points count with the chair stand and distance walked in the 6-minute walk tests, and a positive association of algometer score with the chair stand, distance walked in the 6-minute walk and back scratch tests, yet, weight status seems to play a role in these associations.

The 6-minute walk test in female fibromyalgia patients: relationship with tenderness, symptomatology, quality of life, and coping strategies

The purpose of this study was to examine the relationship between the 6-minute walk test (6-MWT) and tenderness, symptomatology, quality of life, and coping strategies in women with fibromyalgia. One hundred eighteen women with fibromyalgia aged 51.9 ± 7.3 years participated in the study. The examination included the 6-MWT, tender points, and the following questionnaires: Fibromyalgia Impact Questionnaire (FIQ), Short-Form Health Survey 36 (SF-36), and Vanderbilt Pain Management Inventory. Fair correlations between the 6-MWT and the subscales of physical impairment (FIQ) and physical function (SF-36) were observed (ρ -0.365 and 0.347, respectively, both p < .001). The 6-MWT showed a weak relationship with tenderness (ρ 0.201 and -0.191 for algometer score and tender points count, respectively, both p < .05). The relationship between the 6-MWT and global score of FIQ, and FIQ subscales of pain and fatigue were weak (ρ -0.201, -0.211, and -0.226, respectively, all p < .05). The 6-MWT showed a weak relationship with bodily pain and vitality scales of SF-36 (ρ 0.256 and 0.258, respectively, both p = .005) and with passive and active coping strategies (ρ -0.255 and 0.223, both p < .05). This study in women with fibromyalgia shows significant relationships, ranging from weak to fair, between the 6-MWT and tenderness, symptomatology, quality of life, and coping strategies. These findings indicate that functional capacity, as assessed by the distance walked in 6 minutes, might be important when planning the assessment, treatment, and monitoring of patients with fibromyalgia.

Prescription of physical exercise in Crohn's disease

BACKGROUND

Physical exercise may be potentially beneficial for recovering physical condition and improving quality of life in populations suffering from chronic conditions, but little is known about its effects on patients suffering from Crohn's disease.

AIMS

To provide reasonable and conservative recommendations for exercise regimens that appear clinically safe and feasible in patients suffering from Crohn's disease.

METHODS

Relevant clinical studies about the effects of physical exercise on Crohn's disease, written in English language and carried out with human subjects were reviewed.

RESULTS

Few relevant clinical studies have evaluated the effects of an exercise intervention on patients experiencing Crohn's disease. There seem to be two main types of physical interventions that should be recommended: aerobic activity and muscular resistance training.

CONCLUSIONS

Some basic guidelines about how to prescribe physical exercise in Crohn's disease can be provided. However, more research is needed as few studies have been carried out so far.

Potential benefits of non-pharmacological therapies in fibromyalgia

Fibromyalgia (FM) is an incurable common syndrome of non-articular origin, and with no effective treatment by now. A great deal of research has sought to assess the efficacy of different therapies, especially non-pharmacological and low-cost ones, in the reduction of the intensity of symptoms. Despite the availability of a wide range of alternative therapies nowadays, there is little scientific evidence of the potential benefits of most of them, with results being contradictories. The purpose of this paper is to review some of the less well known alternative therapies in FM treatment, to describe the more relevant clinical studies published in this matter, and to analyze the potential effects of the main alternative therapies, in order to verify their efficacy.
