Disability assessment in temporomandibular disorders and masticatory system rehabilitation

The consequences of a disease or condition such as temporomandibular disorders (TMD) include functional limitation and psychosocial disability. These two concepts refer to the individual's experience of limitations in function associated with the affected part of the body and to disarray in one's life, respectively. Models of disability emphasize the individual's self-report in describing these states and the centrality of these concepts as part of the disease and illness process. However, assessment approaches typically used in medicine and especially in dentistry do not yet routinely include these domains. TMD, as a musculoskeletal pain condition, can clearly lead to both limitation and disability, and the available evidence suggests that dentofacial disorders can also lead to both consequences. The relatively low contribution of disease impairment (measured changes in function through objective tests), however, to the reported limitation or disability in either TMD or dentofacial disorders remains complex and poorly understood. This article reviews the overall model of disablement, the necessary properties of measures to assess disablement, the present state of knowledge about these concepts, and what measures should be considered as part of routine assessment.

Effects of spouse-assisted coping skills training and exercise training in patients with osteoarthritic knee pain: a randomized controlled study

This study tested the separate and combined effects of spouse-assisted pain coping skills training (SA-CST) and exercise training (ET) in a sample of patients having persistent osteoarthritic knee pain. Seventy-two married osteoarthritis (OA) patients with persistent knee pain and their spouses were randomly assigned to: SA-CST alone, SA-CST plus ET, ET alone, or standard care (SC). Patients in SA-CST alone, together with their spouses, attended 12 weekly, 2-h group sessions for training in pain coping and couples skills. Patients in SA-CST + ET received spouse-assisted coping skills training and attended 12-weeks supervised ET. Patients in the ET alone condition received just an exercise program. Data analyses revealed: (1) physical fitness and strength: the SA-CST + ET and ET alone groups had significant improvements in physical fitness compared to SA-CST alone and patients in SA-CST + ET and ET alone had significant improvements in leg flexion and extension compared to SA-CST alone and SC, (2) pain coping: patients in SA-CST + ET and SA-CST alone groups had significant improvements in coping attempts compared to ET alone or SC and spouses in SA-CST + ET rated their partners as showing significant improvements in coping attempts compared to ET alone or SC, and (3) self-efficacy: patients in SA-CST + ET reported significant improvements in self-efficacy and their spouses rated them as showing significant improvements in self-efficacy compared to ET alone or SC. Patients receiving SA-CST + ET who showed increased self-efficacy were more likely to have improvements in psychological disability. An intervention that combines spouse-assisted coping skills training and exercise training can improve physical fitness, strength, pain coping, and self-efficacy in patients suffering from pain due to osteoarthritis.

How much disability in rheumatoid arthritis is explained by rheumatoid arthritis?

OBJECTIVE

To measure the proportion of disability explained by disease manifestations compared with nondisease factors in rheumatoid arthritis (RA).

METHODS

A hypothetical model of the disablement process specific for RA was constructed using the demographic, sociocultural, and clinical characteristics of a consecutive cohort of RA patients. Disability was measured with the modified Health Assessment Questionnaire (M-HAQ) and the physical function scale of the Medical Outcomes Study Short Form 36 (SF-36) questionnaire. Independent variables, grouped according to their position in the RA disablement process model, were sequentially entered in a series of hierarchical regression models. The proportion of variance in disability explained by each group of variables was measured by the group's incremental R2.

RESULTS

The overall proportion of disability explained by the full model was 59%. Factors in the main disease-disability pathway explained 33%, of which 3% was explained by disease duration, 5% by the Westergren erythrocyte sedimentation rate, 14% by articular signs and symptoms, and 11% by performance-based functional limitations. External modifiers and contextual variables explained 26% of the variance in disability, of which age and sex accounted for 2%, formal education 4%, psychological status 17%, and symptoms of depression 3%.

CONCLUSION

Both the main disease-disability pathway and factors external to this pathway contribute significantly to disability in RA. These findings provide evidence of the relative influence of psychosocial factors, compared with disease manifestations, on the disability of patients with RA.

Pain in fibromyalgia

Just as our caveman forebears were frail in the face of predatory animals, we are frail in today's society of childhood neglect or abuse, bumper-to-bumper traffic, frustration at work, and multiple daily hassles. The same neuroendocrine systems and pain regulatory mechanisms that protected early man during acute stress are still encoded in our genome, but may be maladaptive in psychologically and physiologically vulnerable people faced with chronic stress. Many patients with fibromyalgia become vulnerable because of the long-lasting psychological and neurophysiological effects of negative experiences in childhood. Ill-equipped with positive cognitive, emotional, and behavioral skills as adults, they display maladaptive coping strategies, low self-efficacy, and negative mood when confronted with the inevitable stressors of life. Psychological distress ensues, which reduces thresholds for pain perception and tolerance (already relatively low in women) even further. Converging lines of psychological and neurobiological evidence strongly suggest that chronic stress-related blunting of the HPA, sympathetic, and other axes of the stress response together with associated alterations in pain regulatory mechanisms may finally explain the pain and fatigue of fibromyalgia. Vulnerable people who can be classified by the ACR criteria as having fibromyalgia do not have a discrete disease. They are simply the most ill in a continuum of distress, chronic pain, and painful tender points in the general population.

The social environment and health in rheumatoid arthritis: marital quality predicts individual variability in pain severity

OBJECTIVE

To examine prospective relations between a wide array of measures of social functioning and pain, while controlling for disease duration and activity and functional grade.

METHODS

As part of a larger study on health care utilization, longitudinal data were collected from 136 Dutch and 98 German outpatients on clinical status and pain. Social data included information on sexual handicap, spouse behavior, loneliness, daily emotional support, and the maintenance of pleasurable life domains. Pain severity was assessed at baseline and 12 months later with standard measures of pain and analyzed with hierarchical regressions.

RESULTS

Social measures obtained at baseline were consistently associated with pain at followup. Depression was a moderate correlate of pain in the Dutch and German samples. The regressions revealed that patient reports of negative spouse behavior (such as avoidance and critical remarks) and baseline depression predicted worse pain outcome, and this association remained significant in analyses controlling for baseline pain. The level of formal education was a weak correlate of disability, emotional support, and pain. Daily emotional support and social life domains associated with positive affect had an indirect influence on outcome. The absence of strong rather than weak social ties was the component of the loneliness construct linked to pain. These associations between social prognostic factors and pain severity, however, were mediated by psychological functioning at baseline.

CONCLUSION

The social environment was found to operate on the core health outcome, pain severity, via several pathways. Social functioning may be affected by rheumatoid arthritis (RA) progression, but it also appears to form a determinant of future health outcome. Not only the status of being married but also the quality of the relationship in terms of long-term stress and emotional support may be useful prognostic factors in RA.

Predictive factors in rheumatoid arthritis

Rheumatoid arthritis (RA), a chronic polyarticular disease affecting about 1% of the adult population of the world, produces significant joint destruction, physical impairment, work disability, and early mortality. Patients with RA may have a slowly or rapidly progressive disease or a self-limited one. To design a rational treatment program for all patients, the clinician must identify early on whether patients are destined to have a rapidly progressive disease. This article reviews socioeconomic, psychological, immunogenetic, and disease-related features that may help to identify such patients.

The relationship of socioeconomic status, race, and modifiable risk factors to outcomes in patients with systemic lupus erythematosus

OBJECTIVE

To study the relationship of race, socioeconomic status (SES), clinical factors, and psychosocial factors to outcomes in patients with systemic lupus erythematosus (SLE).

METHODS

A retrospective cohort was assembled, comprising 200 patients with SLE from 5 centers. This cohort was balanced in terms of race and SES. Patients provided information on socioeconomic factors, access to health care, nutrition, self-efficacy for disease management, health locus of control, social support, compliance, knowledge about SLE, and satisfaction with medical care. Outcome measures included disease activity (measured by the Systemic Lupus Activity Measure), damage (measured by the SLICC/ACR damage index), and health status (measured by the SF-36).

RESULTS

In multivariate models that were controlled for race, SES, center, psychosocial factors, and clinical factors, lower self-efficacy for disease management (P < or = 0.0001), less social support (P < 0.005), and younger age at diagnosis (P < 0.007) were associated with greater disease activity. Older age at diagnosis (P < or = 0.0001), longer duration of SLE (P < or = 0.0001), poor nutrition (P < 0.002), and higher disease activity at diagnosis (P < 0.007) were associated with more damage. Lower self-efficacy for disease management was associated with worse physical function (P < or = 0.0001) and worse mental health status (P < or = 0.0001).

CONCLUSION

Disease activity and health status were most strongly associated with potentially modifiable psychosocial factors such as self-efficacy for disease management. Cumulative organ damage was most highly associated with clinical factors such as age and duration of disease. None of the outcomes measured were associated with race. These results suggest that education and counseling, coordinated with medical care, might improve outcomes in patients with SLE.

Coping with rheumatoid arthritis. How can specialist nurses influence it and promote better outcomes?

Psychological stressors are said to be an important influence on the outcome of chronic illness such as rheumatoid arthritis (Engel, 1977). Helping patients to cope with stressors is identified as a central concept in the delivery of nursing care (Khan et al., 1994). It is thus reasonable to suggest that rheumatology nurses may be key players in the process of coping with rheumatoid arthritis. But in order for rheumatology nurses to be effective players in this process, they need to discourage coping behaviour(s) linked to poor outcomes, and/or promote an overall behaviour pattern linked to a better outcome. Literature showing the link between different coping behaviours and outcome is examined, and cognitive restructuring is emphasized as one method nurses could use. Having identified coping behaviour which is optimal in terms of future outcome, further study of different forms of coping-based educational intervention is suggested, to reveal how such patterns of behaviour can be taught by nurses in the most effective way.

Pain in arthritis and musculoskeletal disorders: the role of coping skills training and exercise interventions

There is growing recognition of the limitations of conventional, biomedical approaches to the management of pain in individuals having arthritis and musculoskeletal disorders. This article provides an overview of newly developed biopsychosocial approaches to the management of pain in this population. The presentation is divided into three sections. In the first section, a biopsychosocial model of pain is presented. This model highlights the role that biological factors (eg., disease severity, comorbid conditions), cognitive-behavioral factors (eg., thoughts, emotions, and behaviors), and environmental factors (eg., spouse or family responses to pain behavior) can play in influencing the pain experience. In the second section, we provide an overview of two newly developed treatment protocols based on the biopsychosocial model of pain: a pain coping skills training protocol and an exercise training protocol. Practical aspects of implementing these protocols are illustrated by highlighting how they are applied in the management of patients having persistent osteoarthritic pain. In the final section of the article, we pinpoint several important future directions for research in this area. Future studies need to explore the utility of combining pain coping skills and exercise training protocols. In addition, there is a need to identify variables that predict patients' response to biopsychosocial treatments.

The implications of depression for pain and disability in rheumatoid arthritis

Depression in rheumatoid arthritis (RA) affects many, but by no means all, persons with the disease. There is evidence that depression bears a significant relationship to pain in RA, although the causal direction is not entirely clear. Likewise, there is strong evidence that depression is a major contributor to the RA disability. Therefore, prevention, early diagnosis, and aggressive treatment of depression are needed to minimize the disability associated with RA.

Promoting patient cooperation with exercise programs: linking research, theory, and practice

Managing patient-nonadherence with prescribed exercise regimens is not an uncommon task for physical therapists working with individuals with arthritis. Yet little is known about the factors that influence patient adherence with exercise programs or therapist knowledge and use of theoretically based adherence management techniques. Survey research with physical therapists and patients was used to provide a database for further insight into the barriers experienced in implementing exercise programs in clinical practice. In this paper, we suggest that the cooperation with an exercise regimen is mediated by the patient's belief system and requires a therapeutic process of mutual inquiry, problem solving, and negotiation between the therapist and patient. Concepts from research, theory, and practice are integrated into a Process Model for Patient-Practitioner Collaboration for use in clinical practice.
