Multidisciplinary approaches for management of fibromyalgia.

Multidisciplinary approaches to fibromyalgia syndrome (FMS) treatment are advocated for treating the complex symptoms and problems confronting many patients. Exercise and cognitive-behavioral strategies together with patient education commonly comprise the multidisciplinary approach to treatment in clinical trials. A review of the research literature suggests that they are effective for decreasing pain and FMS impact and increasing self-efficacy and physical functioning. Limitations of the current evidence base include a lack of studies that include medication treatment as part of the multidisciplinary approach as well as lack of attention to the diversity of patient psychosocial issues that may interfere with treatment effectiveness. The review recommends that further randomized clinical trials be carried out with subgroups of patients using standardized outcome measurements, adequate treatment length and sufficient length of follow-up to be able to observe and document changes in patient symptoms and behaviors over time.

Exercise for patients with fibromyalgia: risks versus benefits.

Although exercise in the form of stretching, strength maintenance, and aerobic conditioning is generally considered beneficial to patients with fibromyalgia (FM), there is no reliable evidence to explain why exercise should help alleviate the primary symptom of FM, namely pain. Study results are varied and do not provide a uniform consensus that exercise is beneficial or what type, intensity, or duration of exercise is best. Patients who suffer from exercise-induced pain often do not follow through with recommendations. Evidence-based prescriptions are usually inadequate because most are based on methods designed for persons without FM and, therefore, lack individualization. A mismatch between exercise intensity and level of conditioning may trigger a classic neuroendocrine stress reaction. This review considers the adverse and beneficial effects of exercise. It also provides a patient guide to exercise that takes into account the risks and benefits of exercise for persons with FM.

A comparison of the SF-36 and Nottingham Health Profile in patients with chronic neuropathic pain.

The aim of this study was to evaluate and compare the psychometric properties of two generic health-related quality of life (HRQoL) instruments, the Short Form Health Survey (SF-36) and the Nottingham Health Profile (NHP) in a group of patients with chronic peripheral neuropathic pain (PNP). The sample consisted of 126 adults (56 men and 70 women) with PNP following a lesion of a peripheral nerve, spinal nerve or nerve root or patients with post-herpetic neuralgia. The battery of tests included visual analogue scales (VASs) for pain assessment and global rating of health and verbal rating scales of pain and other symptoms, as well as patient descriptors. The SF-36 had higher internal consistency reliability coefficients (alpha=0.79, range 0.70-0.90) than the NHP (alpha=0.68, range 0.49-0.79). Correlations between comparable dimensions of the two instruments were significant (range from -0.79 for the physical and mental dimensions to -0.29 for the social dimension) indicating a moderate degree of convergent validity. The study population had significantly worse scores on all dimensions of the two instruments when compared with the general population. Subjects with high VAS scores for pain on movement and those with low global health ratings had poorer scores on the both instruments. Overall, the SF-36 performed somewhat better on psychometric testing than did the NHP. However, the NHP contains dimensions such as sleep and more pain items which might be of particular importance in the PNP population. Since the instruments are short, both could be retained for continued testing in outcome studies of this population.

Quality of life of women with systemic lupus erythematosus or rheumatoid arthritis: domains of importance and dissatisfaction.

The aim of this study was to increase understanding of the domains of life that are important to Swedish women with chronic rheumatic disease and to describe their dissatisfaction with these domains. Fifty women with Systemic Lupus Erythematosus (SLE) and 50 with Rheumatoid Arthritis (RA) were interviewed by telephone regarding their quality of life using five open-ended questions. Content analysis of their responses revealed nine categories: Health/wellness, Family/friends, Work, House/home/living environment, Social support/functional services, Hobbies/cultural activities, Sufficient income, Independence, Integrity/identity. Areas of importance correspond closely to those areas with which they were most dissatisfied. Although the domains identified in both groups were the same, SLE patients expressed more dissatisfaction with their perceived control over their bodies and understanding about their condition on the part of physicians and people in general. RA patients were more dissatisfied with areas of their lives that threatened their independence. Health care providers should be aware of these areas of dissatisfaction so that they can plan strategies to maximize patient quality of life.

Conceptualization and measurement of quality of life as an outcome variable for health care intervention and research.

If health care providers are to be able to document effective outcomes resulting from their interventions, they must first develop clear conceptual definitions for the outcomes, and then select measures that represent these concepts. No consensus exists in the health care disciplines about what quality of life is or how it should be measured. This paper presents historical and conceptual arguments in favour of a particular definition of quality of life, and distinguishes between quality of life and concepts often confused with it in the literature: symptoms, mood, functional status, and general health status. Whether quality of life is actually amenable to change as a result of health care interventions, and whether we ought to be trying to influence clients' quality of life is also discussed. We conclude that quality of life is an important outcome of health care intervention. However, traditional approaches to influencing quality of life may be misdirected, and the relative importance of our interventions to clients--whose opinions matter the most--ought to be put into perspective.

Validity and reliability of the Norwegian version of the Ferrans and Powers Quality of Life Index.

The purpose of this study was to examine the validity and reliability of the Norwegian version of the Ferrans and Powers Quality of Life Index in a sample of 131 men and women with newly diagnosed cancer. The Quality of Life Index was translated into Norwegian using a standardized international approach, including back-translation. The findings showed high internal consistency reliability for the global score (alpha = 0.93 (test)) as well as for the following domains: health and functioning (alpha = 0.88), socio-economic (alpha = 0.82), psychological/spiritual (alpha = 0.82) and family (alpha = 0.79). The test-retest reliability after 3-4 weeks was 0.78 for the global score. A factor analysis partially confirmed the different subscales. In conclusion, the Quality of Life Index was found to be reliable and had sufficient validity to be used for measuring quality of life in Norwegian cancer patients.

Hypothalamic-pituitary-insulin-like growth factor-I axis dysfunction in patients with fibromyalgia.

OBJECTIVE: To investigate the serum levels of insulin-like growth factor-I (IGF-I) in patients with fibromyalgia (FM) compared to healthy controls and patients with other rheumatic diseases, and to explore possible etiologic mechanisms of low IGF-I levels in patients with FM. METHODS: Five hundred patients with FM and 152 controls (74 healthy blood donors, 26 myofascial pain patients and 52 patients with other rheumatic diseases) were studied. All had measurements of acid extracted serum IGF-I. A subset of 90 patients with FM were evaluated for clinical features that might explain low IGF-I levels. Twenty-five patients with FM underwent growth hormone (GH) provocation testing with l-dopa and clonidine. RESULTS: The mean serum IGF-I level in patients with FM was 138 +/- 56 ng/ml and in controls 215 +/- 86 ng/ml (p = 0.00000000001). Low levels of IGF-I were not due to depression, tricyclic medications, nonsteroidal antiinflammatory drugs, poor aerobic conditioning, obesity, or pain level. Patients with focal myofascial pain syndromes had normal IGF-I levels (236 +/- 68), as did most patients with other rheumatic disorders, unless they had concomitant FM. Patients with FM with initially normal levels often had a rapid decline of IGF-I over 1 to 2 years. Most patients with FM with low IGF-I levels failed to secrete GH after stimulation with clonidine and l-dopa. CONCLUSION: Many, but not all, patients with FM have low levels of IGF-I that cannot be explained by clinical associations. These results suggest that low IGF-I levels in patients with FM are a secondary phenomenon due to hypothalamic-pituitary-GH axis dysfunction.

Perceived control: a comparison of women with fibromyalgia, rheumatoid arthritis, and systemic lupus erythematosus using a Swedish version of the Rheumatology Attitudes Index.

This study compared the attitudes of women with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), or fibromyalgia (FM) regarding their perceptions of control and ability to cope with their disease. We also report the validation of a Swedish version of the Rheumatology Attitudes Index (RAI). One hundred thirty-nine women participated in the study by completing the RAI two or three times along with several other self-report and disease severity measures. The Swedish version RAI was found to have acceptable reliability, evidence of validity, sensitivity to change, and two distinct factors of internality and helplessness. In general, patients with RA or SLE perceived higher control over their symptoms than those with FM. FM patients who participated in a self-management experimental program significantly changed their scores on the RAI in a positive direction.

Group treatment of fibromyalgia: a 6 month outpatient program.

OBJECTIVE: To evaluate the impact of a 6 month group therapy program on the treatment of patients with fibromyalgia (FM). Since FM is a common problem in rheumatology practice, a program was designed to treat patients in a group setting using allied health professionals. METHODS: The FM group (15 to 25 patients) met once a week for 6 months. The average session lasted 90 min and consisted of formal lectures, group sessions emphasizing behavior modification, stress reduction techniques, strategies to improve fitness and flexibility and support sessions for spouses/significant others. The 2 major outcome measures were the fibromyalgia impact questionnaire (FIQ) and the total tender point score. Secondary outcome measures were the quality of life scale, questionnaires to assess coping strategies and attitudes to illness, an index of aerobic conditioning, flexibility, distance walked in 6 min., Beck depression and Beck anxiety questionnaires. Patients were followed 2 years and compared to a group of patients outside the program. RESULTS: Between 1989 and 1993 170 patients were evaluated and 104 patients completed the program. At the end of the 6 months 73 (70%) of patients had <11 tender points and FIQ improved 25%. Having a pain profile on MMPI or having major depression, did not predict poorer outcome. Thirty-three patients followed for 2 years after the program continue to show improvement. A control group of 29 patients who never entered the program showed no significant improvement. CONCLUSION: The group treatment of patients with FM in an outpatient setting shows promise; a more formal controlled study is needed to confirm this impression.

Predictors of hand function in patients with rheumatoid arthritis.

OBJECTIVES: The aims of this study were to determine: (1) what factors predict patient self-estimated hand function; (2) what factors predict actual hand function; and (3) the relationship among actual hand function, patient estimates of hand function, and self-assessed activities of daily living (ADL). METHODS: Fifty-two patients with rheumatoid arthritis completed wrist and hand mobility measures, grip strength, pain, stiffness, and estimated hand function tests, along with the Sollerman Grip Function Test (actual hand function), Health Assessment Questionnaire (HAQ), and subscales of the Arthritis Impact Measurement Scales (AIMS). RESULTS: Grip strength and stiffness were the strongest predictors of self-estimated hand function. Flexion and extension deficits in digits II through V were the strongest predictors of actual hand function. Actual hand function and self-estimated hand function were significantly correlated with each other and with the HAQ and AIMS subscales. CONCLUSIONS: Measures of deficit are the most useful in predicting actual hand function, whereas measures of strength and flexibility are most useful for estimated hand function.

The Fibromyalgia Impact Questionnaire, a Swedish translation of a new tool for evaluation of the fibromyalgia patient.

The American Fibromyalgia Impact Questionnaire (FIQ) was translated into Swedish. The FIQ is a brief 10-item self-administered instrument designed to evaluate the special problems bothering fibromyalgia patients. After the translation procedure, 73 Swedish women fibromyalgia patients answered the translated FIQ. The questionnaire was fast and simple to handle both for the patients and the investigators. There was a good level of correspondence between FIQ items and related items in the Health Assessment Questionnaire, the Nottingham Health Profile and the Psychological General Well-Being Index. There were no significant differences in a test-retest analysis. The study has provided evidence that the translated and slightly modified Swedish version of the American Fibromyalgia Impact Questionnaire has the validity and sensitivity to be able to function as a relevant and comprehensible tool to monitor FMS-patients.

Assessing depression in fibromyalgia patients.

PURPOSE: This study investigated the relationships among four methods of detecting depression in patients with fibromyalgia. METHODS: Data were obtained from 100 women (mean age 43 years) who had been diagnosed with fibromyalgia. Instruments included a computerized Diagnostic Interview Schedule (C-DIS), Beck Depression Inventory (BDI), an adjusted "disease-free" BDI (BDI-A), and Minnesota Multiphasic Personality Inventory depression subscale (MMPI-D). Chance-corrected concordance, sensitivity, specificity, and accuracy among the four methods were calculated. RESULTS: The C-DIS detected 22% and BDI-A 29% with current major depression. The BDI and MMPI-D yielded higher estimates of 55% of the 44%, respectively. Agreement on the diagnosis among the four methods was significantly greater than chance. When compared with the C-DIS, the BDI was the most sensitive instrument and the BDI-A most specific.

Physical performance characteristics of women with fibromyalgia.

OBJECTIVE: The aim of this study was to examine physical performance in women with fibromyalgia (FM) using methods that are easy to use in clinical settings and to compare our findings with published norms or a healthy comparison group. METHODS: Measures of shoulder pain and range-of-motion, isometric shoulder endurance, neck rotation, leg strength, hand grip strength, back flexibility, 6-minute walk distance, and symptom duration were completed on 97 subjects with FM. The comparison group was 30 age-matched healthy women. RESULTS: The FM group had significantly lower physical functioning scores on all variables when compared to the healthy group or published norms. When pain at rest was controlled, pain on motion was the most significant predictor of variance in shoulder range of motion, whereas range of motion was the most significant predictor of right shoulder endurance and grip strength of both hands. CONCLUSIONS: Women with FM are markedly below average in physical performance abilities when measured by clinical tests.

Exercise tests as outcome measures.

Outcome assessments of physical fitness attributes such as endurance, strength, and flexibility are not measured routinely in clinical trials or clinical practice in either adults or children with rheumatic diseases. Although physical fitness is not a measure of disease severity, it can be a critical indicator of capacity to function. Adequate fitness is necessary for the performance of positive health behaviors that enhance health status and wellness in spite of chronic disease. The purpose of this paper is to explore the conceptual, methodologic, and analytic issues related to the use of exercise tests as outcome measurements of physical functioning in persons with rheumatic disease.

Education programmes for fibromyalgia patients: description and evaluation.

A firm theoretical basis for patient education in rheumatic disease care has been built up over the past 10 to 15 years. Education in self-management has enabled patients to control symptoms and become partners in care with their health providers. Education for fibromyalgia patients has come to the foreground during the last 5 years as health professionals have come to understand the syndrome better and recognize the role that stress plays in the exacerbation of symptoms. A few controlled trials of various strategies, such as aerobic conditioning and cognitive-behavioural techniques, have been reported recently. All have shown significant benefits to patients with fibromyalgia. Only one controlled trial has studied the effects of a self-management education programme alone. The results of this programme were positive. Self-efficacy and life quality were enhanced. This programme and an uncontrolled programme that integrated many strategies have shown some of the first positive long-term indications that patients who are treated intensively for even a short time can continue to improve as they practice self-management techniques. There is still a need for further documentation of non-drug treatment strategies and especially further research into who is helped by which strategies, the optimal length of time for a programme, and the need for ongoing treatment.

A Swedish version of the short-form McGill Pain Questionnaire.

A short-form of the McGill Pain Questionnaire (SF-MPQ) has been translated into Swedish. One hundred women with either fibromyalgia (FS) or rheumatoid arthritis (RA) filled out the SF-MPQ three times--the RA patients monthly while receiving their routine care, and the FS patients over 6 months while participating in an experimental treatment. Results indicated that the MPQ 15-item descriptor section was internally consistent (Cronbach's alphas .73 to .89), but lacked content validity in the RA sample. Test-retest reliabilities ranged from .45 to .73. Convergent construct validity was demonstrated by significant correlations between the SF-MPQ and other pain measurements. A principal components analysis showed that the 15-item descriptor section has three distinct factors: acute sensory, chronic sensory, and affective. We conclude that the SF-MPQ is reliable and valid for use with FS patients.

A randomized, controlled clinical trial of education and physical training for women with fibromyalgia.

OBJECTIVE: To determine the effectiveness of self-management education and physical training in decreasing fibromyalgia (FMS) symptoms and increasing physical and psychological well being. METHODS: A pretest-posttest control group design was used. Ninety-nine women with FMS were randomly assigned to 1 of 3 groups; 86 completed the study. The education only group received a 6-week self-management course. The education plus physical training group received the course and 6 h of training designed to assist them to exercise independently. The control group got treatment after 3 months. RESULTS: The experimental programs had a significant positive impact on quality of life and self-efficacy. Helplessness, number of days feeling bad, physical dysfunction, and pain in the tender points decreased significantly in one or both of the treated groups when retested 6 weeks after the end of the program. Longterm followup of 67 treated subjects showed significant positive changes on the Fibromyalgia Impact Questionnaire primarily in the physical training group. Among all subjects, 87% were exercising at least 3 times/week for 20 min or more; 46% said they had increased their exercise level since participating in the program; 70% were practicing relaxation strategies as needed; 46% were working at least half time as opposed to 37% at pretest. CONCLUSION: Self-efficacy of the treated groups was enhanced significantly by the program. Other changes were smaller and more delayed than had been expected. Recommendations for future trials include a longer education program, more vigorous physical training, and longterm followup.
