Biofeedback/relaxation training and exercise interventions for fibromyalgia: a prospective trial

A randomized clinical trial of an individualized home-based exercise programme for women with fibromyalgia

OBJECTIVE

To determine the efficacy of a 12-week individualized home-based exercise programme on physical functioning, pain severity and psychological distress for women with fibromyalgia (FM).

METHODS

Seventy-nine women with a primary diagnosis of FM were randomized to a 12-week individualized home-based moderate-intensity exercise programme or to a usual care control group. Outcomes were functional capacity (Fibromyalgia Impact Questionnaire), pain severity and psychological distress. Outcomes were measured at study entry, at the end of the 12-week intervention, and at 3 and 9 months following completion of the intervention.

RESULTS

On the basis of intention-to-treat analyses, a significant improvement in functional capacity at 3 and 9 months following treatment for participants in the exercise group who were more functionally disabled at study entry was observed. At both 3 and 9 months post-treatment, the mean estimated benefit of the intervention was more than 10 points [-12.3 (95% CI, -21.9 to -2.8); -10.8 (95% CI, -21.5 to -0.2)]. Compared with the control group, statistically significant improvements in upper body pain were evident in the exercise group at post-treatment. These between-group differences in upper body pain were maintained at 3 and 9 months post-treatment. No statistically significant group differences on lower body pain and psychological distress were found.

CONCLUSIONS

Home-based exercise, a relatively low-cost treatment modality, has the potential to improve important health outcomes in FM.

Exercise in fibromyalgia

PURPOSE OF REVIEW

Several studies have indicated that physical exercise is beneficial for patients with fibromyalgia. The aim of this article is to review the recent literature relating to exercise in fibromyalgia, specifically articles published between September 2003 and September 2004, to highlight developments in the field.

RECENT FINDINGS

Previous studies indicate that aerobic exercise performed at adequate intensity for an individual can improve function, symptoms, and well-being. A recent study of aerobic exercise showed that training in sedentary women with fibromyalgia using short bouts of exercise produces improvements in health outcomes. A study of aerobic walking resulted in improvements in physical function, symptoms, and distress. Two studies of low-intensity pool exercise reported a positive impact on fibromyalgia symptoms and distress. Two studies of qigong movement therapy were reported, one indicating improvements in symptoms and the other in movement harmony, indicating that this mode of exercise needs to be evaluated further.

SUMMARY

The recent studies support existing literature on the benefits of exercise for patients with fibromyalgia. The outcomes appear to be related to the program design and the characteristics of the populations studied. As the patients with fibromyalgia form a heterogeneous population, more research is required to identify the characteristics of patients who benefit from specific modes of exercise. Moreover, long-term planning is needed to motivate the patients to continue regular exercise. Informing patients about the benefits of exercise and adjusting the exercise intensity to individual limitations enhances adherence. The social support gained by exercising in groups also enhances adherence to exercise.

Six-month and one-year followup of 23 weeks of aerobic exercise for individuals with fibromyalgia

OBJECTIVE

To measure mood and physical function of individuals with fibromyalgia, 6 and 12 months following 23 weeks of supervised aerobic exercise.

METHODS

This is a followup report of individuals who were previously enrolled in 23 weeks of land-based and water-based aerobic exercise classes. Outcomes included the 6-minute walk test, Beck Depression Inventory (BDI), State-Trait Anxiety Inventory, Arthritis Self-Efficacy Scale (ASES), Fibromyalgia Impact Questionnaire (FIQ), tender point count, patient global assessment score, and exercise compliance. Outcomes were measured at the start and end of the exercise classes and 6 and 12 months later.

RESULTS

Analyses were conducted on 29 (intent-to-treat) or 18 (efficacy) subjects. Six-minute walk distances and BDI total scores were improved at followup (all analyses). BDI cognitive/affective scores were improved at the end of 23 weeks of exercise (both analyses) and at the 12-month followup (efficacy analysis only). BDI somatic scores were improved at 6-month (both analyses) and 12-month followup (intent-to-treat only). FIQ and ASES function were improved at all followup points. ASES pain was improved in efficacy analyses only (all followup points). Tender points were unchanged after 23 weeks of exercise and at followup. Exercise duration at followup (total minutes of aerobic plus anaerobic exercise in the preceding week) was related to gains in physical function (6- and 12-month followup) and mood (6-month followup).

CONCLUSION

Exercise can improve physical function, mood, symptom severity, and aspects of self efficacy for at least 12 months. Exercising at followup was related to improvements in physical function and perhaps mood.

Phenomenological lived experience of patients with rheumatoid arthritis

This phenomenological study explored (a) the lived experience of rheumatoid arthritis (RA), (b) the patient's view of the nurse's role, and (c) the patient as comanager of RA. The purposive sample consisted of 6 Caucasian women living in West Virginia. Using Colaizzi's methodology, a rich, exhaustive description of living with RA emerged. Recommendations for nursing care quality focus on providing personalized, holistic, and humanistic care, which may ultimately improve the patient's quality of life.

Effects of a stress-reduction program on psychological function, pain, and physical function of systemic lupus erythematosus patients: a randomized controlled trial

OBJECTIVE

To assess the effects of a stress-reduction program on pain, psychological function, and physical function in persons with systemic lupus erythematosus (SLE) who experience pain.

METHODS

Ninety-two SLE patients were assigned randomly to receive either biofeedback-assisted cognitive-behavioral treatment (BF/CBT), a symptom-monitoring support (SMS) intervention, or usual medical care (UC) alone.

RESULTS

BF/CBT participants had significantly greater reductions in pain and psychological dysfunction compared with the SMS group (pain, P = 0.044; psychological functioning, P < 0.001) and the UC group (pain, P = 0.028; psychological functioning, P < 0.001). BF/CBT had significantly greater improvement in perceived physical function compared with UC (P = 0.035), and improvement relative to SMS was marginally significant (P = 0.097). At a 9-month followup evaluation, BF/CBT continued to exhibit relative benefit compared with UC in psychological functioning (P = 0.023).

CONCLUSION

This study supports the utility of a brief stress management program for short-term improvement in pain, psychological function, and perceived physical function among persons with SLE who experience pain.

[Fibromyalgia and facial expression]

QUESTION

Do female inpatients with fibromyalgia (FM) differ from healthy women in their nonverbal affective behavior?

METHODS

The data culled from 15 interviews with female FM inpatients and 15 interviews with healthy women were analyzed and the analyses of facial expression were subsequently correlated with gaze behavior.

RESULTS

FM patients exhibited neither a reduction of total activity of facial expression nor of absolute frequency of primary affects in comparison to healthy subjects who did (also in eye contact) however exhibit a significantly higher proportion of "genuine joy" and lower proportion of "contempt."

CONCLUSION

The absence of reduced total activity of facial expression is in contrast to the elaborate descriptions of symptoms provided by the patients, but detailed analyses show that elements which stabilize relationships are lacking and that dissociative elements are implanted in the interactions.

Effectiveness of exercise in management of fibromyalgia

PURPOSE OF REVIEW

Exercise was established as an integral part of the nonpharmacological treatment of fibromyalgia approximately 20 years ago. Since then many studies have investigated the effects of exercise-either alone or in combination with other interventions. This review will discuss the benefits of exercise alone and provide practical suggestions on how patients can exercise without causing a long-term exacerbation of their pain.

RECENT FINDINGS

Short-term exercise programs for individuals with fibromyalgia have consistently improved physical function, especially physical fitness, and reduced tenderpoint pain. Exercise has also produced improvements in self-efficacy. These effects can persist for periods of up to 2 years but may require participants to continue to exercise. Most exercise studies have examined the effects of moderately intense aerobic exercise. Only in the past 2 years have muscle-strengthening programs, in isolation, been evaluated. To be well tolerated, exercise programs must start at a level just below the capacity of the participants and then progress slowly. Even with these precautions, exercise may still produce tolerable, short-term increases in pain and fatigue that should abate within the first few weeks of exercising.

SUMMARY

Future studies should investigate the possible benefits of low-intensity exercise and test strategies that may enhance long-term compliance with exercise. Individuals with fibromyalgia also need to be able to access community exercise programs that are appropriate for them. This may require community instructors to receive instruction on exercise prescription and progression for individuals with fibromyalgia.

Fibromyalgia, physical activity, and daily functioning: the importance of efficacy and health-related quality of life

OBJECTIVE

To determine whether individuals with fibromyalgia (FM) who are more physically active differ in various psychosocial characteristics (i.e., self-efficacy, health-related quality of life [HRQL]) from those who are less active, and whether those who function better on a daily basis also differ in these characteristics from their less able counterparts.

METHODS

The predominantly female sample (n = 86) consisted of individuals medically diagnosed with FM. Measures included symptom variables, physical activity frequency and intensity, daily functioning, HRQL, efficacy for physical activity, FM pain, and other FM symptoms.

RESULTS

Discriminant function analyses to predict physical activity status (P < 0.0001) and functional ability status (P = 0.03) were significant. The variables of physical activity efficacy, pain efficacy, and the physical HRQL component were the best predictors.

CONCLUSION

Support for the importance of perceived control and HRQL for engaging in higher levels of physical activity and daily functioning was demonstrated. Future research must continue to examine psychosocial factors that affect patients' functioning with FM in order to enhance their well-being.

Effects of T'ai Chi exercise on fibromyalgia symptoms and health-related quality of life

BACKGROUND

Fibromyalgia (FM), one of the most common musculoskeletal disorders, is associated with high levels of impaired health and inadequate or limited symptom relief. The cause of this complex syndrome is unknown, and there is no known cure. Numerous research results indicate that a combination of physical exercise and mind-body therapy is effective in symptom management. T'ai Chi, an ancient Chinese exercise, combines physical exercise with mindbody therapy.

PURPOSE

To investigate the effects of T'ai Chi exercise on FM symptoms and health-related quality of life.

DESIGN

Pilot study, one group pre-to-post posttest design.

METHODS

Participants with FM (n = 39) formed a single group for 6 weeks of 1-hour, twice weekly T'ai Chi exercise classes. FM symptoms and health-related quality of life were measured before and after exercise.

FINDINGS

Twenty-one participants completed at least 10 of the 12 exercise sessions. Although the dropout rate was higher than expected, measurements on both the Fibromyalgia Impact Questionnaire (FIQ) (Buckhardt, Clark, & Bennett, 1991) and the Short Form-36 (SE-36) (Ware & Sherbourne, 1992) revealed statistically significant improvement in symptom management and health-related quality of life.

IMPLICATIONS FOR NURSING RESEARCH

Knowledge of interventions to enhance health for the patient with musculoskeletal problems is a National Association of Orthopaedic Nurses priority. Tai Chi is potentially beneficial to patients with FM. Further research is needed to support evidence-based practice.

Applying exercise to the management of fibromyalgia

Fibromyalgia, chronic fatigue syndrome, and related illnesses fall under the spectrum of chronic multisymptom illnesses (CMI). This constellation of syndromes often is defined by chronic pain, unremitting fatigue, cognitive difficulties, and various other symptoms. In treating these illnesses, pharmacotherapy generally is the mode of choice, with exercise being overlooked often. However, research has shown that exercise is quite beneficial in reducing pain and fatigue in this population and should be included as part of a multimodal therapy regimen. This article reviews the exercise and CMI literature and provides a model for applying these evidence-based guidelines to a clinical population.

Psychological and behavioural therapies in fibromyalgia and related syndromes

Psychological and behavioural therapies are being applied to patients with fibromyalgia (FM) with increasing frequency. The rationale for including psychological therapies is not for the treatment of co-morbid mood disorders, but rather to manage the many non-psychiatric psychological and social factors that comprise pain perception and its maintenance. This chapter reviews the involvement of mental health professionals under both the biomedical and biopsychosocial models of illness and describes cognitive behavioural therapy (CBT), a commonly used form of psychological therapy in the management of chronic pain conditions. The empirical literature supports the use of CBT with FM in producing modest outcomes across multiple domains, including pain, fatigue, physical functioning and mood. Greatest benefits appear to occur when CBT is used adjunctively with exercise. While the benefits are not curative or universally obtained by all patients, the benefits are sufficiently large to encourage future refinement of CBT for this population of patients.

The effect of combined therapy (ultrasound and interferential current) on pain and sleep in fibromyalgia

Multidisciplinary treatment has proven to be the best therapeutic option to fibromyalgia (FM) and physiotherapy has an important role in this approach. Considering the controversial results of electrotherapy in this condition, the aim of this study was to assess the effects of combined therapy with pulsed ultrasound and interferential current (CTPI) on pain and sleep in FM. Seventeen patients fulfilling FM criteria were divided into two groups, CTPI and SHAM, and submitted to pain and sleep evaluations. Pain was evaluated by body map (BM) of the painful areas; quantification of pain intensity by visual analog scale (VAS); tender point (TP) count and tenderness threshold (TT). Sleep was assessed by inventory and polysomnography (PSG). After 12 sessions of CTPI or SHAM procedure, patients were evaluated by the same initial protocol. After treatment, CTPI group showed, before and after sleep, subjective improvement of pain in terms of number (BM) and intensity (VAS) of painful areas (P<0.001, both); as well as objective improvement, with decrease in TP count and increase in TT (P<0.001, both). Subjective sleep improvements observed after CTPI treatment included decrease in morning fatigue and in non-refreshing sleep complaint (P<0.001, both). Objectively, PSG in this group showed decrease in sleep latency (P<0.001) and in the percentage of stage 1 (P<0.001), increase in the percentage of slow wave sleep (P<0.001) and in sleep cycle count (P<0.001). Decrease in arousal index (P<0.001), number of sleep stage changes (P<0.05) and wake time after sleep onset (P<0.05), were also observed and no difference regarding pain or sleep parameters were verified after SHAM procedure. This study shows that CTPI can be an effective therapeutic approach for pain and sleep manifestations in FM.

Complementary and alternative medicine in fibromyalgia and related syndromes

Complementary and alternative medicine (CAM) has gained increasing popularity, particularly among individuals with fibromyalgia syndrome (FMS) for which traditional medicine has generally been ineffective. A systematic review of randomized controlled trials (RCTs) and non-RCTs on CAM studies for FMS was conducted to evaluate the empirical evidence for their effectiveness. Few RCTs achieved high scores on the CONSORT, a standardized evaluation of the quality of methodology reporting. Acupuncture, some herbal and nutritional supplements (magnesium, SAMe) and massage therapy have the best evidence for effectiveness with FMS. Other CAM therapies have either been evaluated in only one RCT with positive results (Chlorella, biofeedback, relaxation), in multiple RCTs with mixed results (magnet therapies), or have positive results from studies with methodological flaws (homeopathy, botanical oils, balneotherapy, anthocyanidins, dietary modifications). Lastly, other CAM therapies have neither well-designed studies nor positive results and are not currently recommended for FMS treatment (chiropractic care).

Physical exercise in fibromyalgia and related syndromes

Fibromyalgia and related syndromes are characterized by chronic pain and fatigue. This chapter identifies the types of exercise that are effective for these patients and provides recommendations for exercise prescriptions. Based on a systematic review of randomized controlled studies of exercise, we suggest that low-intensity aerobic exercise, such as walking, can improve function and symptoms. Aerobic exercise performed twice a week at moderate intensity can improve aerobic capacity and reduce tenderness. Pool exercise can improve function, distress and symptoms. Strength training at adequate load can improve strength without exacerbation of symptoms. Most patients tolerate low-intensity exercise. High-intensity exercise should be undertaken with caution. Due to the large variability of functioning and symptom severity in patient populations, exercise prescriptions should be individualized and should include a long-term plan to maximize functioning and wellbeing. Studies with larger populations, allowing subgroup analyses regarding benefits and adverse effects of programmes, are needed.

Improved sleep may reduce arthritis pain

Studies indicate that pain interferes with sleep and, in turn, sleep disturbances increase pain. Statistics show that up to 60% of those with arthritis experience pain during the night. But despite these findings, sleep is not generally addressed as a major treatment concern among this population. This article reviews the relationship between pain and sleep; sleep issues as they relate to 3 common types of arthritis--osteoarthritis, rheumatoid arthritis, and fibromyalgia; and holistic approaches that may be used by the patient in the self-management of pain and sleep.

Effects of a 1.5-day multidisciplinary outpatient treatment program for fibromyalgia: a pilot study

OBJECTIVE

The purpose of this pilot study was to determine the effect of a 1.5-day multidisciplinary fibromyalgia treatment program on impact of illness, depression, and life fulfillment.

DESIGN

A sample of 100 consecutive enrollees in a 1.5-day multidisciplinary group outpatient fibromyalgia treatment program between February 14, 2000, and May 9, 2000, in a tertiary medical center was used for this study. The Fibromyalgia Impact Questionnaire, the Life Fulfillment and Satisfaction Scales, and the Center for Epidemiologic Studies Depression Scale were administered to subjects immediately preceding the treatment program and by mail 1 mo after completing the program.

RESULTS

The 78 subjects who returned their surveys 1 mo after treatment demonstrated significant improvement in the area of the impact of illness as measured by the Fibromyalgia Impact Questionnaire total score (51.3-44.7, P < 0.002). There was no significant improvement in depressive symptoms (P < 0.056) or the level of life fulfillment (P < 0.53). Subjects with depression improved on the Fibromyalgia Impact Questionnaire to the same degree as those without depression. The 22 nonresponders did not differ significantly from the responders in the variables of sex, age, pretreatment Fibromyalgia Impact Questionnaire score, marital status, educational level, family income, duration of symptoms, or history of depression.

CONCLUSIONS

These results suggest that a 1.5-day multidisciplinary fibromyalgia treatment program does have a significant positive effect on the impact of illness among patients with fibromyalgia with or without concomitant depression and may be a cost-effective model for the treatment of these patients.

Long-term exercise training in persons with spinal cord injury: effects on strength, arm ergometry performance and psychological well-being

STUDY DESIGN

Randomized controlled trial of exercise training in persons with spinal cord injury.

OBJECTIVE

The purpose of this study was to examine the effects of 9 months of twice-weekly exercise training on strength, arm ergometry performance, and indices of psychological well-being and quality of life.

SETTING

Centre for Health Promotion and Rehabilitation, McMaster University, Hamilton, Ontario, Canada.

METHODS

Thirty-four men and women (aged 19-65 years) with traumatic spinal cord injury (C4-L1; ASIA A-D) of 1-24 years duration volunteered to participate, and were randomized into exercise (EX; n=21) and control (CON; n=13) groups. Twenty-three subjects (11 EX; 12 CON) successfully completed the 9-month study. Subjects were assessed for one repetition maximum (1RM) strength, arm ergometry performance, and several indices of quality of life and psychological well-being at baseline, 3, 6, and 9 months.

RESULTS

At baseline, there were no significant differences between groups in age, submaximal arm ergometry performance, muscle strength, or psychological well-being. Following training, the EX group had significant increases in submaximal arm ergometry power output (81%; P<0.05), and significant increases in upper body muscle strength (19-34%; P<0.05); no significant changes occurred in CON. Participants in EX reported significantly less pain, stress and depression after training, and scored higher than CON in indices of satisfaction with physical function, level of perceived health and overall quality of life (P<0.05). Exercise adherence (per cent of prescribed sessions attended) in those subjects who completed the 9 months of training was 82.5%.

CONCLUSIONS

These results demonstrate that long-term twice-weekly exercise training in this population is feasible, and results in significant gains in both physical and psychological well-being.

Measuring exercise-induced mood changes in fibromyalgia: a comparison of several measures

OBJECTIVE

To compare scales measuring exercise-induced changes in mood.

METHODS

Mood changes in a randomized, 23-week controlled trial of exercise were assessed using the Beck Depression Inventory (BDI), Center for Epidemiologic Studies Depression Scale (CES-D), State Trait Anxiety Inventory (STAI), Fibromyalgia Impact Questionnaire, and the Mental Health Inventory (MHI). Effect sizes and t-tests were computed on 23-week change scores. Scales were deemed to be confounded if items addressed sleep disturbances, fatigue, or effort (symptoms of both mood disturbances and fibromyalgia).

RESULTS

Efficacy (15 exercise subjects) and intent-to-treat analyses (27 exercise subjects) generated medium effects for BDI (total, cognitive), MHI depression (efficacy only), and CES-D (intent-to-treat only) scales. BDI (total, cognitive), MHI (depression, positive affect, total [MHI-5]), and STAI scales distinguished exercise from control subjects at 23 weeks in all analyses. BDI somatic and CES-D scales were deemed to be confounded.

CONCLUSION

We recommend the BDI cognitive, STAI, and MHI-5 scales to measure depression, anxiety, and general mood, respectively, in patients with fibromyalgia.

Beneficial therapeutic effects of physical training and relaxation therapy in women with coronary syndrome X

BACKGROUND AND PURPOSE

New types of illness are being identified continuously. Owing to the demands for evidence-based practice, physiotherapeutic interventions need to be investigated scientifically prior to application in a new patient population. Coronary syndrome X (syndrome X) is a chronic pain disorder with exercise-induced chest pain despite angiographically normal coronary arteries. Patients with syndrome X constitute a therapeutic problem with considerable residual morbidity associated with functional limitation and reduced quality of life. Therefore, the aim of the present study was to investigate the effects of physical training and relaxation therapy on exercise capacity and quality of life in patients with syndrome X.

METHOD

A single-blind, randomized controlled trial design was used. Twenty-four female patients aged 41-65 years were randomly assigned to three groups: A, B and C. All groups were similar at baseline for physical fitness level. Group A performed physical training for eight weeks at 50% of baseline VO2max and group B participated in relaxation therapy for eight weeks. Group C acted as control subjects without any intervention. Before and after the eight-week periods, subjects were assessed by means of several measures of exercise capacity and quality of life.

RESULTS

The measured variables did not change in the control group during the eight weeks. VO2max (< 0.02), work rate (< 0.002) and distance walked during six minutes (< 0.003) increased only after physical training. The tolerated exertion during six minutes of walking (< 0.05) and the health-related quality of life, measured both by the Stress and Crisis Inventory (SCI) and the Sickness Impact Profile (SIP) (< 0.04), improved after both physical training and relaxation therapy. The general coping capacity, measured by the Sense of Coherence (SOC) questionnaire, remained unchanged in all the groups.

CONCLUSIONS

Female patients with syndrome X benefit from physical training in terms of exercise capacity and quality of life and from relaxation therapy in terms of quality of life.

Evaluation of a patient-centred approach in generalized musculoskeletal chronic pain/fibromyalgia patients in primary care

The aim of this paper is to assess whether patient-centred consultations are more effective than the usual style of consultations used by general practitioners with patients suffering from benign chronic musculoskeletal pain and fibromyalgia. It also seeks to evaluate the differential characteristics of these two clinical groups of symptoms. The study was designed as a cluster randomised and simple blind trial. Twenty general practitioners took part and 110 patients were recruited. Compared with patients who received the usual treatment from their family physician, those who received a patient-centred approach showed greater improvement after 1 year in terms of psychological distress (anxiety) and number of tender points, as well as showing positive trends in some important outcomes such as pain intensity. Significantly better results were observed in those patients suffering chronic pain than in those with fibromyalgia, particularly as regards associated symptoms, self-rated pain and physical mobility as measured by the Nottingham health profile.

Systematic review of randomized controlled trials of nonpharmacological interventions for fibromyalgia

OBJECTIVE

Little is known of the effectiveness of nonpharmacological interventions for fibromyalgia syndrome (FMS). The authors therefore carried out a systematic review from 1980 to May 2000 of randomized controlled trials (RCTs) of nonpharmacological interventions for FMS.

METHOD

A search of computerized databases was supplemented by hand searching of bibliographies of key publications. The methodological quality of studies included in the review was evaluated independently by two researchers according to a set of formal criteria. Discrepancies in scoring were resolved through discussion.

RESULTS

The review yielded 25 RCTs, and the main categories of interventions tested in the studies were exercise therapy, educational intervention, relaxation therapy, cognitive-behavioral therapy, acupuncture, and forms of hydrotherapy. Methodological quality of studies was fairly low (mean score = 49.5/100). Most studies had small samples (median for individual treatment groups after randomization = 20), and the mean power of the studies to detect a medium effect ( > or = 0.5) was 0.36. Sixteen studies had blinded outcome assessment, but patients were blinded in only 6 studies. The median longest follow-up was 16 weeks. Statistically significant between-group differences on at least one outcome variable were reported in 17 of the 24 studies.

CONCLUSIONS

The varying combinations of interventions studied in the RCTs and the wide range of outcome measures used make it hard to form conclusions across studies. Strong evidence did not emerge in respect to any single intervention, though preliminary support of moderate strength existed for aerobic exercise. There is a need for larger, more methodologically rigorous RCTs in this area.

A realistic approach to managing patients with fibromyalgia

Fibromyalgia syndrome is common and variable in impact, with some patients having a milder and shorter duration of symptoms and others suffering significant and prolonged pain. Disability also varies. It is thought that the syndrome arises from a disordered neurophysiology that, through links to central control inputs, involves emotions, thoughts, and cognitions. Social and psychological sequelae contribute to and result from this process. The biopsychosocial model of disease epitomizes fibromyalgia. Although management may be difficult at times, and much needs to be done, the growing appreciation of strategies that use this described model and the knowledge of the potential reversibility of the syndrome are resulting in improved outcomes.

The influence of age on fibromyalgia symptoms

OBJECTIVES

Studies of the influence of age on health and well-being in chronically ill patients have produced mixed findings. This study examined young (20-39), middle-aged (40-59), and older (60-85) individuals with fibromyalgia (FMS), a chronic pain condition. The purpose of this study was to determine whether there were differences among the age groups in symptomatology and to examine potential mediating psychosocial variables.

METHODS

Participants were 600 (95% female, mean age = 54, SD = 11) diagnosed FMS patients who were members of a health maintenance organization. Multivariate analyses of covariance were used to examine differences.

RESULTS

There were significant differences among the age groups in most of the variables: With increasing age symptom duration increased but FMS symptomatology decreased. No age differences were found among the psychosocial mediators. The results suggest that the effects of FMS decrease over time.

Prescribed exercise in people with fibromyalgia: parallel group randomised controlled trial

OBJECTIVES

To evaluate cardiovascular fitness exercise in people with fibromyalgia.

DESIGN

Randomised controlled trial.

SETTING

Hospital rheumatology outpatients. Group based classes took place at a "healthy living centre."

PARTICIPANTS

132 patients with fibromyalgia.

INTERVENTIONS

Prescribed graded aerobic exercise (active treatment) and relaxation and flexibility (control treatment).

MAIN OUTCOME MEASURES

Participants' self assessment of improvement, tender point count, impact of condition measured by fibromyalgia impact questionnaire, and short form McGill pain questionnaire.

RESULTS

Compared with relaxation exercise led to significantly more participants rating themselves as much or very much better at three months: 24/69 (35%) v 12/67 (18%), P=0.03. Benefits were maintained or improved at one year follow up when fewer participants in the exercise group fulfilled the criteria for fibromyalgia (31/69 v 44/67, P=0.01). People in the exercise group also had greater reductions in tender point counts (4.2 v 2.0, P=0.02) and in scores on the fibromyalgia impact questionnaire (4.0 v 0.6, P=0.07).

CONCLUSIONS

Prescribed graded aerobic exercise is a simple, cheap, effective, and potentially widely available treatment for fibromyalgia.

Management of dysautonomia in fibromyalgia

The realization of dysautonomia in FM has opened the possibility for new and different therapeutic interventions. Much more research is needed to better define the role of ANS in the pathogenesis of FM. If this research supports current hypotheses, therapeutic trials with disciplines and substances intended to correct autonomic dysfunction will be indicated.

Nonpharmacologic management strategies in fibromyalgia

Clinicians using the results of the extant research base can take an optimistic view of the role of nonpharmacologic treatment strategies for fibromyalgia. There were no negative outcomes in any of the reviewed studies, although in a few studies the experimental treatment did not prove to be more effective than the attention control. Rather than viewing this negatively, one could look more closely at the attention control groups and attempt to better understand what they contained that worked as an active treatment. A number of trials include a follow-up component and all but one of them find maintenance of at least one outcome change. Maintenance of changes is more likely to occur when the patient continues to participate in the experimental activity long-term. Patients especially need strategies that help them continue in exercise regimens. Unlike cognitive skills strategies that once learned are likely to become part of a person's coping repertoire, both exercise and behavioral strategies, like progressive muscle relaxation, need to be performed on a consistent basis in order to have their effect. The goals of increased self-efficacy, symptom reduction, increased functional status and quality of life along with decreased inappropriate use of health care resources are realistic when patients persevere in their use of strategy combinations and receive support from their providers.

Treatment of fatigue in fibromyalgia

Clearly, fatigue is a large and challenging problem for those suffering from fibromyalgia. It adds greatly to the morbidity and disability associated with the disease. In the management of this specific symptom in fibromyalgia, attention should first be focused on identifying comorbidities that may be present and contribute to fatigue. As with other symptoms of fibromyalgia, education is a critical component of management. This can be done by the practitioner, with available free resources, or with specialized cognitive behavioral programs. This education process can be augmented with a variety of other nonpharmacologic therapies, especially very gradually increasing, low-impact, aerobic exercise programs. Numerous pharmacologic therapies may also be helpful as an adjunct to treatment. Classes of compounds that raise central levels of norepinephrine or dopamine appear to be the most specific for management of fatigue. There are also many medications used to combat fatigue in other disorders that have not yet been adequately explored as to the possible benefits in alleviating the fatigue of fibromyalgia. Advances in the management of fatigue in fibromyalgia are likely to come from a variety of directions. Easier access to well designed nonpharmacologic therapies is essential, because these treatments are underutilized in clinical practice at present. Improvements in pharmacologic therapies will come from new insights into mechanisms, especially those that might only be present in subsets of patients and would respond to more targeted therapies.

Fibromyalgia Pain and Substance P Decrease and Sleep Improves After Massage Therapy

Massage therapy has been observed to be helpful in some patients with fibromyalgia. This study was designed to examine the effects of massage therapy versus relaxation therapy on sleep, substance P, and pain in fibromyalgia patients. Twenty-four adult fibromyalgia patients were assigned randomly to a massage therapy or relaxation therapy group. They received 30-minute treatments twice weekly for 5 weeks. Both groups showed a decrease in anxiety and depressed mood immediately after the first and last therapy sessions. However, across the course of the study, only the massage therapy group reported an increase in the number of sleep hours and a decrease in their sleep movements. In addition, substance P levels decreased, and the patients' physicians assigned lower disease and pain ratings and rated fewer tender points in the massage therapy group.

Mind-body interventions: applications for social work practice

In the past decade, we have seen an increase in the popularity of mind-body medicine as an alternative or complement to traditional health care interventions. This paper explores the history of mind-body medicine and how particular mind-body interventions focusing on stress reduction and relaxation can be useful complements to social work practice. Four types of mind-body interventions are described, research on their effectiveness is reviewed, conclusions are drawn, and the applicability to social work practice is discussed. Given existing empirical support for the effectiveness of these interventions, the authors suggest that efforts at both the systems and individual levels, including changes in social work education, can be made to enhance their use in traditional health settings, as well in other types of settings.

Central nervous system mechanisms of pain in fibromyalgia and other musculoskeletal disorders: behavioral and psychologic treatment approaches

Pain is one of the most important and challenging consequences of musculoskeletal disorders. This article examines the role of central nervous system structures in the physiology of pain. It also describes the neuromatrix, a construct that provides a framework for understanding the interaction between physiologic mechanisms and psychosocial factors in the development and maintenance of chronic pain. This construct suggests that behavioral and psychologic interventions may alter the pain experience primarily through their effects on emotional states and cognitive processes. The literature on cognitive-behavioral interventions for patients with rheumatoid arthritis and osteoarthritis indicates that they are well-established treatments for these disorders. However, the efficacy of these interventions for patients with fibromyalgia has not been established. It is anticipated that the development of valid measures of readiness for behavioral change may allow investigators to identify the patients with musculoskeletal disorders who are most likely to benefit from cognitive-behavioral intervention.

Exercise for treating fibromyalgia syndrome

BACKGROUND

Fibromyalgia (FMS) is a syndrome expressed by chronic widespread body pain which leads to reduced physical function and frequent use of health care services. Exercise training is commonly recommended as a treatment.

OBJECTIVES

The objective of this systematic review was to examine the efficacy of exercise training as an treatment for FMS.

SEARCH STRATEGY

We searched 6 electronic bibliographies for studies of exercise training in FMS: MEDLINE (1966-12/2000), CINAHL (1982-12/2000), HealthSTAR (1990-12/2000), Sports Discus (1975-05/2000), EMBASE (1974-05/2000) and the Cochrane Controlled Trials Register (2000, issue 4). We also reviewed the reference lists from identified articles including reviews and meta-analyses of treatment studies.

SELECTION CRITERIA

Randomized trials focused on cardiorespiratory endurance, muscle strength and/or flexibility as treatment for FMS were selected.

DATA COLLECTION AND ANALYSIS

Two reviewers independently identified trials meeting inclusion criteria, rated the methodologic quality using 2 standardized validated instruments, evaluated the adequacy of the exercise training stimulus using the American College of Sports Medicine (ACSM) criteria and evaluated the results. Disagreements were resolved through active discussion and consensus. High quality training studies had scores of 50% or greater on van Tulder methodologic criteria and met the minimum training standards of ACSM. Outcome variables were grouped into 7 constructs: pain, tender points, physical function, global well being, self efficacy, fatigue & sleep, and psychological function. Two reviewers independently extracted data on study characteristics, results and point estimates for selected variables, and used consensus to address discrepancies.

MAIN RESULTS

Sixteen trials involving a total of 724 participants were assigned at random to: exercise intervention groups (n=379), control groups (n=277), or groups receiving an alternate treatment (n=68). Seven studies were high quality training studies: 4 aerobic training, 1 a mixture of aerobic, strength and flexibility training, 1 strength training and 2 with exercise training as part of a composite treatment. Flexibility protocols were never described in sufficient detail to allow evaluation. The four high quality aerobic training studies reported significantly greater improvements in the exercise groups versus control groups in aerobic performance (17.1% increase in aerobic performance with exercise versus 0.5% increase in the control groups), tender point pain pressure threshold (28.1% increase versus 7.0% decrease) and improvements in pain (11.4% decrease in pain versus 1.6% increase). Poor description of exercise protocols was common, with insufficient information on intensity, duration, frequency and mode of exercise. Adverse events were also poorly reported.

REVIEWER'S CONCLUSIONS

Supervised aerobic exercise training has beneficial effects on physical capacity and FMS symptoms. Strength training may also have benefits on some FMS symptoms. Further studies on muscle strengthening and flexibility are needed. Research on the long-term benefit of exercise for FMS is needed.

Effect of a randomized, controlled trial of exercise on mood and physical function in individuals with fibromyalgia

OBJECTIVE

To evaluate the effect of exercise on mood and physical function in individuals with fibromyalgia.

METHODS

Subjects were randomly assigned to an exercise (EX) or control (CTL) group. EX subjects participated in 3 30-minute exercise classes per week for 23 weeks. Subjects were tested at entry and at 6, 12, and 23 weeks. Tests included the Beck Depression Inventory (BDI), 6-minute walk, State-Trait Anxiety Inventory (STAI), Mental Health Inventory (MHI), Fibromyalgia Impact Questionnaire (FIQ), Arthritis Self-Efficacy Scale (ASES), and a measure of tender points and knee strength.

RESULTS

Fifty subjects (27 EX, 23 CTL) completed the study, and 31 (15 EX, 16 CTL) met criteria for efficacy analyses. In efficacy analyses, significant improvements were seen for EX subjects in 6-minute walk distances, BDI (total, cognitive/ affective), STAI, FIQ, ASES, and MHI (3 of 5 subscales) scores. These effects were reduced but remained during intent-to-treat analyses.

CONCLUSION

Exercise can improve the mood and physical function of individuals with fibromyalgia.

Test of a nursing intervention to promote adjustment to fibromyalgia

PURPOSE

This was a test to detect whether a 4-week cognitive behavioral nursing program was effective in increasing adjustment to fibromyalgia (FM) and if the treatment effect would last over time.

DESIGN

This was a control and treatment group experimental longitudinal study with outcome measures obtained at pretest and every 3 months for 1 year.

SAMPLE

A sample of 71 subjects continued their participation throughout the first year of the study.

FINDINGS

Treatment subjects had improved posttreatment adjustment and symptom severity compared to control subjects. When subjects with high pretest psychosocial distress (n = 5) were removed from the analysis, these findings were statistically significant.

IMPLICATIONS FOR NURSING PRACTICE

The article can provide direction for developing new comprehensive nursing intervention for patients seen with orthopaedic problems. The intervention schedule may help nurses expand their use of interventions for FM patients. Orthopaedic nurses are especially suited for this challenge.

Complementary and alternative therapies for fibromyalgia

Fibromyalgia (FM) is a syndrome of chronic widespread musculoskeletal pain that is accompanied by sleep disturbance and fatigue. Clinical treatment usually includes lifestyle modifications and pharmacologic interventions meant to relieve pain, improve sleep quality, and treat mood disorders. These therapies are often ineffective or have been shown in clinical studies to have only short-term effectiveness. Pharmacologic treatments have considerable side effects. Patients may have difficulty complying with exercise-based treatments. Thus, patients seek alternative therapeutic approaches and physicians are routinely asked for advice about these treatments. This article reviews nontraditional treatment alternatives, from use of nutritional and herbal supplements to acupuncture and mind-body therapy. Little is known about efficacy and tolerance of complementary and alternative therapies in FM and other chronic musculoskeletal pain syndromes. Most studies on these treatments have been performed for osteoarthritis, rheumatoid arthritis, or focal musculoskeletal conditions. Clinical trials are scarce; the quality of these trials is often criticized because of small study population size, lack of appropriate control interventions, poor compliance, or short duration of follow-up. However, because of widespread and growing use of alternative medicine, especially by persons with chronic illnesses, it is essential to review efficacy and adverse effects of complementary and alternative therapies.

The Treatment of Fibromyalgia with Cranial Electrotherapy Stimulation

In cranial electrotherapy stimulation (CES), micro-current levels of electrical stimulation are passed across the head via electrodes clipped to the ear lobes. After successful clinical use of CES with fibromyalgia patients in our clinic, it was decided to test these results with a double-blind, placebo-controlled study in which 60 randomly assigned patients were given 3 weeks of 1-hour-daily CES treatments, sham CES treatments, or were held as wait-in-line controls for any placebo effect in the sham-treated patients. Treated patients showed a 28% improvement in tender point scores, and a 27% improvement in self-rated scores of general pain level. The number of subjects rating their quality of sleep as poor dropped from 60% at the beginning of the study to 5%. In addition, there were significant gains in the self-rated feelings of well-being and quality of life, plus gains in six stress-related psychological test measures. No placebo effect was found among the sham-treated controls. A theoretical role of CES in affecting the brain's pain message mechanisms and/or neurohormonal control systems is discussed. It is concluded that CES is as effective as the drug therapies in several trials, with no negative side effects, and deserves further consideration as an additional agent for the treatment of fibromyalgia.

Treating fibromyalgia with a brief interdisciplinary program: initial outcomes and predictors of response

OBJECTIVES

To evaluate the efficacy of a brief, intense treatment program for fibromyalgia and to determine which patient characteristics are associated with a better treatment response.

PATIENTS AND METHODS

Two self-report measures, the Fibromyalgia Impact Questionnaire (FIQ) and the Multidimensional Pain Inventory (MPI), were administered before patients completed treatment and 1 month after participating in the program. The main outcome measure was the difference in FIQ score and MPI scale before and after program participation.

RESULTS

Of 139 patients who met the American College of Rheumatology criteria for fibromyalgia, 100 chose to participate in the 1 1/2-day Fibromyalgia Treatment Program at the Mayo Clinic, Rochester, Minn. Of these 100 patients, 74 completed the follow-up surveys. Patients were less affected by fibromyalgia after participation in the treatment program. This was demonstrated by a posttreatment improvement in the total FIQ score (P<.001), the MPI pain severity score (P<.001), and the MPI interference score (P=.01). The 1 patient characteristic found to be significantly associated (P<.001) with a better response to treatment was a high pretreatment level of impairment from fibromyalgia, as measured by the pretreatment FIQ score.

CONCLUSIONS

A brief interdisciplinary program for treating fibromyalgia reduced some associated symptoms. Patients more severely affected by fibromyalgia may benefit most from this approach. Clinicians may apply these findings to develop beneficial and convenient treatment programs for patients with fibromyalgia.

Effects of pool-based and land-based aerobic exercise on women with fibromyalgia/chronic widespread muscle pain

OBJECTIVE

To examine the effects of pool-based (PE) and land-based (LE) exercise programs on patients with fibromyalgia.

METHODS

The outcomes were assessed by the Fibromyalgia Impact Questionnaire, the Arthritis Self-Efficacy Scale, and tests of physical capacity.

RESULTS

Eighteen subjects in the PE group and 16 in the LE group performed a structured exercise program. After 20 weeks, greater improvement in grip strength was seen in the LE group compared with the PE group (P < 0.05). Statistically significant improvements were seen in both groups in cardiovascular capacity, walking time, and daytime fatigue. In the PE group improvements were also found in number of days of feeling good, self-reported physical impairment, pain, anxiety, and depression. The results were mainly unchanged at 6 months followup.

CONCLUSION

Physical capacity can be increased by exercise, even when the exercise is performed in a warm-water pool. PE programs may have some additional effects on symptoms.

Strength training induced adaptations in neuromuscular function of premenopausal women with fibromyalgia: comparison with healthy women

OBJECTIVE

To investigate the effects of 21 weeks' progressive strength training on neuromuscular function and subjectively perceived symptoms in premenopausal women with fibromyalgia (FM).

METHODS

Twenty one women with FM were randomly assigned to experimental (FM(T)) or control (FM(C)) groups. Twelve healthy women served as training controls (H(T)). The FM(T) and H(T) groups carried out progressive strength training twice a week for 21 weeks. The major outcome measures were muscle strength and electromyographic (EMG) recordings. Secondary outcome measures were pain, sleep, fatigue, physical function capacity (Stanford Health Assessment Questionnaire), and mood (short version of Beck's depression index).

RESULTS

Female FM(T) subjects increased their maximal and explosive strength and EMG activity to the same extent as the H(T) group. Moreover, the progressive strength training showed immediate benefits on subjectively perceived fatigue, depression, and neck pain of training patients with FM.

CONCLUSIONS

The strength training data indicate comparable trainability of the neuromuscular system of women with FM and healthy women. Progressive strength training can safely be used in the treatment of FM to decrease the impact of the syndrome on the neuromuscular system, perceived symptoms, and functional capacity. These results confirm the opinion that FM syndrome has a central rather than a peripheral or muscular basis.

Reliability of the six-minute walk test in people with fibromyalgia

OBJECTIVE

To determine the test-retest reliability of the 6-minute walk test in people with fibromyalgia.

METHODS

Twenty-six subjects (27-59 years of age) performed 3 walk tests over consecutive days before and after a 4-week treatment program. Reliability was determined using a one-way repeated measures analysis of variance and the intraclass correlation coefficient (ICC2,1).

RESULTS

Reliability of the 6-minute walk test was excellent both at program intake (ICC2,1 = 0.91) and program completion (ICC2,1 = 0.98). On program intake, significant differences (P < 0.01) were found between test 1 (478 +/- 61 m) and test 2 (492 +/- 57 m), and between test 1 and test 3 (495 +/- 60 m). On program completion, there were no significant differences across the 3 replicate tests (507 m, 505 m, and 509 m).

CONCLUSIONS

The 6-minute walk test is a reliable measure in people with fibromyalgia. In this study, two trials were required to achieve a stable walk performance before a treatment program. This learning effect was not present following the intervention.

Pain in patients with fibromyalgia syndrome

Chronic diffuse pain and hyperalgesia are two cardinal features of pain in fibromyalgia syndrome (FMS). Advancement in understanding the pathophysiology and treatment efficacy often depends on pain that is defined and measured. Pain is a subjective phenomenon that we can measure only by indirect methods. In this article, we provide methodological guidelines for pain assessment and review recent developments in understanding pain mechanisms and evaluating treatments in FMS. Finally, we demonstrate the heterogeneity of the FMS population and suggest the need for matching treatments to patient characteristics in order to improve clinical outcomes.

A meta-analysis of fibromyalgia treatment interventions

OBJECTIVE

To evaluate and compare the efficacy of pharmacological and nonpharmacological treatments of fibromyalgia syndrome (FMS).

METHODS

This meta-analysis of 49 fibromyalgia treatment outcome studies assessed the efficacy of pharmacological and nonpharmacological treatment across four types of outcome measures-physical status, self-report of FMS symptoms, psychological status, and daily functioning.

RESULTS

After controlling for study design, antidepressants resulted in improvements on physical status and self-report of FMS symptoms. All nonpharmacological treatments were associated with significant improvements in all four categories of outcome measures with the exception that physically-based treatment (primarily exercise) did not significantly improve daily functioning. When compared, nonpharmacological treatment appears to be more efficacious in improving self-report of FMS symptoms than pharmacological treatment alone. A similar trend was suggested for functional measures.

CONCLUSION

The optimal intervention for FMS would include nonpharmacological treatments, specifically exercise and cognitive-behavioral therapy, in addition to appropriate medication management as needed for sleep and pain symptoms.

Complementary medicine treatments for fibromyalgia syndrome

Fibromyalgia is a chronic-pain-related syndrome associated with high rates of complementary and alternative medicine (CAM) use. Among the many CAM therapies frequently used by fibromyalgia patients, empirical research data exist to support the use of only three: (1) mind-body, (2) acupuncture, and (3) manipulative therapies for treating fibromyalgia. The strongest data exist for the use of mind-body techniques (e.g. biofeedback, hypnosis, cognitive behavioural therapy), particularly when utilized as part of a multidisciplinary approach to treatment. The weakest data exist for manipulative techniques (e.g. chiropractic and massage). The data supporting the use of acupuncture for fibromyalgia are only moderately strong. Also, for some fibromyalgia patients, acupuncture can exacerbate symptoms, further complicating its application for this condition. Further research is needed not only in these three areas, but also for other treatments being frequently utilized by fibromyalgia patients.

Physical and other non-pharmacological interventions for fibromyalgia

There is little empirical evidence for the effectiveness of physical and other non-pharmacological approaches to the management of fibromyalgia. Although a number of studies have been conducted into such approaches, many of these are uncontrolled, and relatively few randomized controlled trials of appropriate size and methodological rigour have been carried out. This chapter provides an overview of the evidence available under the following headings: exercise, EMG biofeedback training, electrotherapy and acupuncture, patient education and self-management programmes, multimodal treatment approaches, and other interventions. It is hard to reach firm conclusions from the literature, owing to the variety of interventions that have been evaluated and the varying methodological quality of the studies concerned. Nonetheless, in terms of specific interventions, exercise therapy has received a moderate degree of support from the literature, and has been subjected to more randomized studies than any other intervention. In contrast, there is little or no evidence available for most types of electrotherapy. In terms of overall management strategies, a multimodal programme of management, including physical, psychological and educational components and delivered in a multidisciplinary setting, has gained some support from descriptive and experimental studies, and accords with current understanding of the aetiology and clinical features of fibromyalgia. There is a clear need for further systematic evaluation of the effectiveness of non-pharmacological treatment approaches in fibromyalgia.

Psychological and behavioral approaches to pain management for patients with rheumatic disease

This article reviews the efficacy of the psychological and behavioral pain management interventions that have been evaluated among adult patients with rheumatoid arthritis (RA), osteoarthritis (OA), and fibromyalgia (FM). Using published criteria for empirically validated interventions, it is concluded that cognitive-behavioral therapies and the Arthritis Self-Management Program represent well-established treatments for pain among patients with RA and OA. These interventions involve education, training in relaxation and other coping skills, and rehearsal of these skills in patients' home and work environments. There currently are no psychological or behavioral interventions for pain among FM patients that can be considered as well-established treatments. Future intervention research should use clinically meaningful change measures in addition to conventional tests of statistical significance, attend to the pain management needs of children, and assess whether outcomes produced in university-based treatment centers generalize to those in local treatment settings.
