Therapeutic ultrasound for the treatment of rheumatoid arthritis

Effects of low-level laser therapy and therapeutic ultrasound on Freund's complete adjuvant-induced knee arthritis model in rats

OBJECTIVES

The aim of this study was to evaluate and monitor the effect of low-level laser therapy (LLLT) and therapeutic ultrasound (TU) alone, or combined with intra-articular prednisolone (P) in Freund's complete adjuvant (FCA)-induced knee arthritis model in rats.

MATERIALS AND METHODS

A total of 56 adult male Wistar rats were divided into seven groups: control (C), disease control (RA), P, TU, LLLT (L), P + TU (P+TU), P + LLLT (P+L) groups. The skin temperature, radiography, joint volume, serum rheumatoid factor (RF), interleukin (IL)-1β, serum tumor necrosis factor-alpha (TNF-α), and histopathological evaluation of joint were performed.

RESULTS

Thermal imaging and radiographic examination provided results consistent with the severity of the disease. The mean joint temperature (°C) was the highest in the RA (36.2±1.6) group on Day 28. The P+TU and P+L groups significantly decreased radiological scores at the end of the study. The rat serum TNF-α, IL-1β, and RF levels in all groups were significantly higher compared to the C group (p<0.05). Compared to the RA group, serum TNF-α, IL-1β, and RF levels were significantly lower in the treatment groups (p<0.05). The P+TU and P+L group was showed minimal chondrocyte degeneration and cartilage erosion and mild cartilage fibrillation and mononuclear cell infiltration of synovial membrane compared to the P, TU, and L group.

CONCLUSION

The LLLT and TU effectively reduced inflammation. In addition, a more effective result was obtained from the use of LLLT and TU combined with intra-articular P. This result may be due to insufficient dose of LLLT and TU, thus further studies should be focus on at higher dose ranges on FCA arthritis model in rats.

Non-pharmacological treatment in difficult-to-treat rheumatoid arthritis

Although the management of rheumatoid arthritis (RA) has improved remarkably with new pharmacological therapies, there is still a significant part of patients not reaching treatment goals. Difficult-to-treat RA (D2TRA) is a complex entity involving several factors apart from persistent inflammation, thereafter requiring a holistic management approach. As pharmacological treatment options are often limited in D2TRA, the need for non-pharmacological treatments (NPT) is even more pronounced. The mechanism of action of non-pharmacological treatments is not well investigated, NPTs seem to have a complex, holistic effect including the immune, neural and endocrine system, which can have a significant additive benefit together with targeted pharmacotherapies in the treatment of D2TRA. In this review we summarize the current knowledge on different NPT in rheumatoid arthritis, and we propose a NPT plan to follow when managing D2TRA patients.

[Rehabilitation in rheumatic diseases and osteoporosis-a multidisciplinary task]

Advances in medications and changes in therapeutic options have significantly reduced limitations in functional capacity and quality of life for patients with rheumatic diseases and osteoporosis, but there is still a large number of patients in whom the diseases do not take the desired course. Older rheumatic patients also often have comorbidities that require a multidisciplinary and multimodal approach to therapy. Rehabilitation measures are, therefore, an important part of the treatment concept for these patients in order to maintain their functional health, social participation, and, in the case of those who are still working, in particular their gainful employment. They can help to limit sequelae, preserve existing functions, reduce pain, and maintain the quality of life of those affected. The article aims to provide an overview of the rehabilitative therapy concept and the level of evidence for individual forms of therapy.

Autoinflammatory Diseases and Physical Therapy

Autoinflammatory diseases (AIDs) constitute a group of clinical conditions, characterized by recurrent episodes of systemic inflammation, due to dysregulation of the innate immune system, without involving autoantibodies or antigen-specific T-cells. The patients exhibit recurrent episodes of fever with potentially serious complications and may have classic rheumatologic symptoms, including joint, skin, eye and muscle inflammation. Therefore, musculoskeletal problems and impaired quality of life can be anticipated as unavoidable consequences. In this regards any approach to ease the burden of symptoms and compensate the functional deficits are the main objectives of rehabilitation approach. For patients with inflammatory arthritis, physical therapy and rehabilitation methods have an important role in reducing joint pain and stiffness, preventing deformity, reconstructing muscle tissue and improving function. In order to justify the integration of rehabilitation approach in the management of AIDs and to determine the optimal protocols to use in this group of patients, well-designed, comprehensive, longitudinal, clinical trials using physical therapy centred outcomes are greatly needed.

Effect of low-intensity pulsed ultrasound therapy on a rat knee joint contracture model

[Purpose] Histopathological investigation of the effects of low-intensity pulsed ultrasound (LIPUS) on joint components using a rat knee joint contracture model. [Subjects and Methods] Nineteen, 9-week-old Wistar male rats were divided into a control group (n=6) and an experimental group. Rats in the experimental group underwent cast immobilization of the right rear limb for 8 weeks. They were then randomly divided into a non-treatment group (n=6), which was raised under normal conditions for 4 weeks, and a treatment group (n=7), which underwent LIPUS for 4 weeks. LIPUS irradiation was performed at a frequency of 3 MHz, an intensity of 30 mW/cm², and a pulse rate of 20% duty cycle. Irradiation was performed once daily for 10 min, 5 days per week. At the end of this period, tissue specimens in which the knee sagittal plane could be observed were prepared and observed using an optical microscope. [Results] The extension-limiting angle of the knee joint was significantly less in the treatment group compared with the non-treatment group. The posterior joint capsule was significantly thicker only in the non-treatment group, and the density was 53.5 ± 7.5% for the control group, 77.2 ± 5.7% for the non-treatment group, and 69.2 ± 2.9% for the treatment group, with significant differences existing across all groups. [Conclusion] LIPUS may widen the space between collagen fiber bundles of the joint capsule, thereby improving the range of motion.

Therapeutic ultrasound for venous leg ulcers

BACKGROUND

Venous leg ulcers are a type of chronic, recurring, complex wound that is more common in people aged over 65 years. Venous ulcers pose a significant burden to patients and healthcare systems. While compression therapy (such as bandages or stockings) is an effective first-line treatment, ultrasound may have a role to play in healing venous ulcers.

OBJECTIVES

To determine whether venous leg ulcers treated with ultrasound heal more quickly than those not treated with ultrasound.

SEARCH METHODS

We searched the Cochrane Wounds Specialised Register (searched 19 September 2016); the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library 2016, Issue 8); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations, MEDLINE Daily and Epub Ahead of Print) (1946 to 19 September 2016); Ovid Embase (1974 to 19 September 2016); and EBSCO CINAHL Plus (1937 to 19 September 2016). We also searched three clinical trials registries and the references of included studies and relevant systematic reviews. There were no restrictions based on language, date of publication or study setting.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that compared ultrasound with no ultrasound. Eligible non-ultrasound comparator treatments included usual care, sham ultrasound and alternative leg ulcer treatments.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed the search results and selected eligible studies. Details from included studies were summarised using a data extraction sheet, and double-checked. We attempted to contact trial authors for missing data.

MAIN RESULTS

Eleven trials are included in this update; 10 of these we judged to be at an unclear or high risk of bias. The trials were clinically heterogeneous with differences in duration of follow-up, and ultrasound regimens. Nine trials evaluated high frequency ultrasound; seven studies provided data for ulcers healed and two provided data on change in ulcer size only. Two trials evaluated low frequency ultrasound and both reported ulcers healed data.It is uncertain whether high frequency ultrasound affects the proportion of ulcers healed compared with no ultrasound at any of the time points evaluated: at seven to eight weeks (RR 1.21, 95% CI 0.86 to 1.71; 6 trials, 678 participants; low quality evidence - downgraded once for risk of bias and once for imprecision); at 12 weeks (RR 1.26, 95% CI 0.92 to 1.73; 3 trials, 489 participants; moderate quality evidence - downgraded once for imprecision); and at 12 months (RR 0.93, 95% CI 0.73 to 1.18; 1 trial, 337 participants; low quality evidence - downgraded once for unclear risk of bias and once for imprecision).One trial (92 participants) reported that a greater percentage reduction in ulcer area was achieved at four weeks with high-frequency ultrasound, while another (73 participants) reported no clear difference in change in ulcer size at seven weeks. We downgraded the level of this evidence to very low, mainly for risk of bias (typically lack of blinded outcome assessment and attrition) and imprecision.Data from one trial (337 participants) suggest that high frequency ultrasound may increase the risk of non-serious adverse events (RR 1.29, 95% CI 1.02 to 1.64; moderate quality evidence - downgraded once for imprecision) and serious adverse events (RR 1.21, 95% CI 0.78 to 1.89; moderate quality evidence downgraded once for imprecision).It is uncertain whether low frequency ultrasound affects venous ulcer healing at eight and 12 weeks (RR 3.91, 95% CI 0.47 to 32.85; 2 trials, 61 participants; very low quality evidence (downgraded for risk of bias and imprecision)).High-frequency ultrasound probably makes little or no difference to quality of life (moderate quality evidence, downgraded for imprecision). The outcomes of adverse effects, quality of life and cost were not reported for low-frequency ultrasound treatment.

AUTHORS' CONCLUSIONS

It is uncertain whether therapeutic ultrasound (either high or low frequency) improves the healing of venous leg ulcers. We rated most of the evidence as low or very low quality due to risk of bias and imprecision.

Effects of underwater ultrasound therapy on pain, inflammation, hand function and quality of life in patients with rheumatoid arthritis - a randomized controlled trial

•

Underwater ultrasound therapy is a useful procedure to treat inflammation in patients with RA.

•

Underwater ultrasound therapy is suitable to treat irregular body parts, because the transmission coefficient is high and the reflection is low in water.

•

The improvements were only observed in the short term (at the end of 2 weeks of treatment).

Objectives

To investigate the effects of underwater ultrasound (US) therapy in 48 patients with moderately active rheumatoid arthritis (disease activity score in 28 joints [DAS28] > 3.2 and < 5.1).

Methods

Patients randomly assigned to the ultrasound group (n = 25) received underwater continuous ultrasound therapy to both wrists and hands for 7 min per session with an intensity of 0.7 W/cm² for 10 sessions. The control group (n = 23) received sham treatment under the same conditions. At baseline, at the end of treatment (end of Week 2) and at the follow-up visit (Week 14), the following outcomes were evaluated: disease activity (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], tender and swollen joint counts, pain on a visual analog scale, DAS28, hand function (fist making, wrist extension and flexion, hand grip strength) and quality of life (Health Assessment Questionnaire [HAQ]).

Results

A significant decrease in C-reactive protein at the end of Week 2 and Week 14 compared to control group (mean between-group difference at 2 weeks = −5.77, 95% CI = −10.86 to −0.68, mean between-group difference at 14 weeks = −5.07, 95% CI = −10.13 to −0.01), and non-significant decrease in DAS28 was observed. By the end of treatments at the end of week 2, ultrasound alleviated pain significantly (mean between-group difference at two weeks = −8.35 95% CI = −16.12 to −0.58), as well as improved left wrist extension compared to the control group (mean between-group difference at 14 weeks = 4.35, 95% CI = 1.09–7.60).

Conclusion

Underwater ultrasound therapy was better than sham treatment at the end of 2 weeks of treatment, but not at long term (14 weeks) in patients with rheumatoid arthritis.

Effectiveness of ultrasound treatment applied with exercise therapy on patients with ankylosing spondylitis: a double-blind, randomized, placebo-controlled trial

The aim of our study was to evaluate effectiveness of ultrasound treatment applied with exercise therapy in patients with ankylosing spondylitis. Fifty-two patients, who were diagnosed according to modified New York criteria, were aged 25-60, and have spine pain, were randomly assigned to two groups. Ultrasound (US) and exercise therapy were applied to treatment group (27); placebo US treatment and exercise therapy were applied to control group (25). Patients were evaluated before treatment, at the end of treatment, and 4 weeks after the treatment. Daily and night pain, morning stiffness, patient global assessment (PGA), doctor global assessment (DGA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire, Ankylosing Spondylitis Disease Activity Score (ASDAS) erythrocyte sedimentation rate (ESR), and ASDAS C-reactive protein (CRP) were used as clinical parameters. In US group, all parameters showed significant improvements at 2 and 6 weeks, in comparison with the baseline. In placebo US group, significant improvement was obtained for all parameters (except tragus-to-wall distance and modified Schober test at 2 weeks and lumbar side flexion and modified Schober test at 6 weeks). Comparison of the groups showed significantly superior results of US group for parameters of BASMI (p < 0.05), tragus-wall distance (p < 0.05), PGA (p < 0.01), and DGA (p < 0.05) at 2 weeks as well as for the parameters of daily pain (p < 0.01), PGA (p < 0.05), DGA (p < 0.01), BASDAI (p < 0.05), ASDAS-CRP (p < 0.05), ASDAS-ESR (p < 0.01), lumbar side flexion (p < 0.01), the modified Schober test (p < 0.01), and ASQoL (p < 0.05) at 6 weeks. Our study showed that ultrasound treatment increases the effect of exercise in patients with ankylosing spondylitis.

The physical therapy prescription

Physical therapy was first noted in the time of Hippocrates. The physical therapy visit includes a complete history, physical examination, and development of a treatment plan. Health care providers usually initiate a referral based on physical examination, symptoms, or a specific diagnosis. Physical therapy has been shown to be particularly helpful for musculoskeletal ailments, and has a growing body of evidence for use.

Non-pharmacological interventions for fatigue in rheumatoid arthritis

BACKGROUND

Fatigue is a common and potentially distressing symptom for people with rheumatoid arthritis with no accepted evidence based management guidelines. Non-pharmacological interventions, such as physical activity and psychosocial interventions, have been shown to help people with a range of other long-term conditions to manage subjective fatigue.

OBJECTIVES

To evaluate the benefit and harm of non-pharmacological interventions for the management of fatigue in people with rheumatoid arthritis. This included any intervention that was not classified as pharmacological in accordance with European Union (EU) Directive 2001/83/EEC.

SEARCH METHODS

The following electronic databases were searched up to October 2012, Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; AMED; CINAHL; PsycINFO; Social Science Citation Index; Web of Science; Dissertation Abstracts International; Current Controlled Trials Register; The National Research Register Archive; The UKCRN Portfolio Database. In addition, reference lists of articles identified for inclusion were checked for additional studies and key authors were contacted.

SELECTION CRITERIA

Randomised controlled trials were included if they evaluated a non-pharmacological intervention in people with rheumatoid arthritis with self-reported fatigue as an outcome measure.

DATA COLLECTION AND ANALYSIS

Two review authors selected relevant trials, assessed risk of bias and extracted data. Where appropriate, data were pooled using meta-analysis with a random-effects model.

MAIN RESULTS

Twenty-four studies met the inclusion criteria, with a total of 2882 participants with rheumatoid arthritis. Included studies investigated physical activity interventions (n = 6 studies; 388 participants), psychosocial interventions (n = 13 studies; 1579 participants), herbal medicine (n = 1 study; 58 participants), omega-3 fatty acid supplementation (n = 1 study; 81 participants), Mediterranean diet (n = 1 study; 51 participants), reflexology (n = 1 study; 11 participants) and the provision of Health Tracker information (n = 1 study; 714 participants). Physical activity was statistically significantly more effective than the control at the end of the intervention period (standardized mean difference (SMD) -0.36, 95% confidence interval (CI) -0.62 to -0.10; back translated to mean difference of 14.4 points lower, 95% CI -4.0 to -24.8 on a 100 point scale where a lower score means less fatigue; number needed to treat for an additional beneficial outcome (NNTB) 7, 95% CI 4 to 26) demonstrating a small beneficial effect upon fatigue. Psychosocial intervention was statistically significantly more effective than the control at the end of the intervention period (SMD -0.24, 95% CI -0.40 to -0.07; back translated to mean difference of 9.6 points lower, 95% CI -2.8 to -16.0 on a 100 point scale, lower score means less fatigue; NNTB 10, 95% CI 6 to 33) demonstrating a small beneficial effect upon fatigue. For the remaining interventions meta-analysis was not possible and there was either no statistically significant difference between trial arms or findings were not reported. Only three studies reported any adverse events and none of these were serious, however, it is possible that the low incidence was in part due to poor reporting. The quality of the evidence ranged from moderate quality for physical activity interventions and Mediterranean diet to low quality for psychosocial interventions and all other interventions.

AUTHORS' CONCLUSIONS

This review provides some evidence that physical activity and psychosocial interventions provide benefit in relation to self-reported fatigue in adults with rheumatoid arthritis. There is currently insufficient evidence of the effectiveness of other non-pharmacological interventions.

Therapeutic ultrasound for venous leg ulcers

BACKGROUND

Venous leg ulcers pose a significant burden for patients and healthcare systems. Ultrasound (US) may be a useful treatment for these ulcers.

OBJECTIVES

To determine whether US increases the healing of venous leg ulcers.

SEARCH STRATEGY

We searched the Cochrane Wounds Group Specialised Register (searched 24 February 2010); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2010); Ovid MEDLINE (1950 to February Week 2 2010); In-Process & Other Non-Indexed Citations (searched 24 February 2010); Ovid EMBASE 1980 to 2010 Week 07; EBSCO CINAHL 1982 to 24 February 2010.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing US with no US.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed the search results and selected eligible studies. Details from included studies were summarised using a data extraction sheet, and double-checked. We tried to contact trial authors for missing data.

MAIN RESULTS

Eight trials were included; all had unclear, or high, risks of bias, with differences in duration of follow-up, and US regimens. Six trials evaluated high frequency US and five of these reported healing at 7 - 8 weeks. Significantly more patients healed with US than without it at 7 - 8 weeks (pooled RR 1.4, 95% CI 1.0 to 1.96), but later assessments at 12 weeks showed the increased risk of healing with US was no longer statistically significant (pooled RR 1.47, 95% CI 0.99 to 2.20). One poor-quality study of high-frequency US found no evidence of an effect on healing after three weeks' treatment.Two trials evaluated low frequency US and reported healing at different time points. Both trials reported no evidence of a difference in the proportion of ulcers healed with US compared with no US: both were significantly underpowered.

AUTHORS' CONCLUSIONS

The trials evaluating US for venous leg ulcers are small, poor-quality and heterogeneous. There is no reliable evidence that US hastens healing of venous ulcers. There is a small amount of weak evidence of increased healing with US, but this requires confirmation in larger, high-quality RCTs. There is no evidence of a benefit associated with low frequency US.

Conservative treatments for rheumatoid arthritis in the foot and ankle

Rheumatoid arthritis (RA) is a systemic inflammatory disease that attacks peripheral joints, causing their destruction. Several pharmacologic therapies and physical modalities are available for its treatment. Because of the progressive nature of RA, complementary and alternative medicine therapy in conjunction with conventional medicine is administered to patients with RA. This article discusses the presence of undiagnosed RA in the foot and ankle and reviews the concurrent nonoperative measures in treatment, including pharmacologic and physical modalities.

Non-drug therapies in early rheumatoid arthritis

Non-pharmacological treatment modalities are often used as an adjunct to drug therapy in patients with rheumatoid arthritis (RA). The aim of this overview is to summarize the available evidence on the effectiveness of these modalities in early RA. The few available randomized controlled trials that have specifically investigated patients with early RA support the effectiveness of dynamic exercise and cognitive behavioural interventions, and to a lesser extent of joint protection programmes and foot orthoses. The effectiveness of multidisciplinary team-care programmes, specialist nurse care, electro-physical modalities (including passive hydrotherapy), wrist orthoses, and dietary interventions have not been studied in patients with early RA. Current recommendations on the usage of non-pharmacological treatment modalities in sets of guidelines on the management of early RA vary with respect to their scope, strength and level of detail. The results of this review indicate a need for further investigation into the most clinically effective and cost-effective strategies to deliver non-pharmacological treatment modalities as well as comprehensive arthritis care models in early RA.

[Evidence-based physiotherapeutic strategies for musculoskeletal pain]

Inflammatory rheumatic disorders usually progress towards morphologic and functional deficits and thus cause substantial impairment of physical health. Amongst the therapeutic options physiotherapeutic strategies are essential and are often required to maintain the individual's quality of life. Because of the large variety of physiotherapeutical approaches, differentiated clinical examination is needed in order to implement physiotherapeutics in a treatment plan that is based on pathophysiologic and regeneration-specific aspects. The article presents a current overview of evidence-based physiotherapeutic strategies for musculoskeletal pain reduction in daily practice.

Therapeutic ultrasound for venous leg ulcers

BACKGROUND

Venous leg ulceration is a common problem, representing a significant burden on the patient and the healthcare system. They are caused by venous insufficiency and tend to be chronic and recurring. Management usually includes use of wound dressings plus compression stockings or bandages. It has been suggested that therapeutic ultrasound may have an adjuvant effect and promote healing however its effects are unclear.

OBJECTIVES

To determine whether therapeutic ultrasound increases the healing of venous leg ulcers.

SEARCH STRATEGY

We searched the Cochrane Wounds Group Specialised Register (August 2007), The Cochrane Central Register of Controlled Trials (CENTRAL) - The Cochrane Library Issue 3, 2007, Ovid MEDLINE - 1950 to July Week 4 2007, Ovid EMBASE - 1980 to 2007 Week 31, Ovid CINAHL - 1982 to August Week 1 2007.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing therapeutic ultrasound with placebo (sham) ultrasound, or other (standard) treatment.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed the results of the searches for eligible RCTs and obtained full reports. A third author assessed the results of the update searches for eligible RCTs. Details from the eligible studies were extracted and summarised by a review author using a data extraction sheet. Attempts were made to contact trial authors to obtain missing data or for clarification.

MAIN RESULTS

A total of eight eligible trials were identified and were all of either medium or high risk of bias. Five trials compared ultrasound therapy with placebo (sham) ultrasound, three trials compared ultrasound therapy with standard treatment. Trials varied in terms of ulcer size, regimen and duration of follow up. No trials individually found a statistically significant difference in the number of ulcers healed between any of the therapies, however on pooling trials (different durations of follow up) for the outcome of risk healing, significantly more ulcers were completely healed with ultrasound (RR 1.49, 95% CI 1.07 to 2.09). Some trials also found that ultrasound increases the rate of change of wound size and/or reduces the size of existing ulcers, whilst other trials did not find this effect to be significant. When all trials reporting percentage ulcer area remaining were pooled there was a significant benefit associated with ultrasound (WMD -5.34%, 95% CI -8.38 to -2.30).

AUTHORS' CONCLUSIONS

The available evidence suggests that ultrasound may increase healing of venous leg ulcers. These conclusions are based on the results of only eight small studies of generally poor quality and therefore should be interpreted with caution.

Nonpharmacological treatments in early rheumatoid arthritis: clinical practice guidelines based on published evidence and expert opinion

OBJECTIVE

To develop clinical practice guidelines for the use of nonpharmacological treatments in patients with early rheumatoid arthritis (RA), using the evidence-based approach and expert opinion.

METHODS

A scientific committee used a Delphi prioritization procedure to select five questions. Evidence providing answers to the five questions was sought in the literature and presented to a panel of rheumatologists. The panel developed five detailed recommendations, filling gaps in evidence with their expert opinion. The strength of each recommendation was determined.

RESULTS

Of the 565 publications retrieved by the literature review, 198 were included in the analysis. The five recommendations on nonpharmacological treatments for early RA were validated by a final vote among all participants. The recommendations are as follows: (1) physicians may decide to provide joint protection education to patients with potentially severe early RA, with the knowledge that structured joint protection programs have not been found effective; (2) physical exercise and sports can be recommended to patients with early RA; muscle strength exercises are advisable; (3) in patients with early RA, metatarsal pain and/or foot alignment abnormalities should be looked for regularly, and appropriate insoles should be prescribed if needed; (4) dietary measures and nutritional supplements are not indicated as part of the treatment of early RA; (5) elimination diets, particularly those with low intakes of dairy products, should be discouraged in patients with early RA.

CONCLUSION

These recommendations should help to improve practice uniformity and, ultimately, to improve the management of RA.

Successfully living with chronic arthritis

The treatment and care of patients with rheumatoid arthritis (RA) is complex and various health professionals with different areas of expertise may be involved. The objective of this article is to review the treatments and their efficacy as provided by health care professionals in RA care. The requirements for further research in this area are formulated. To achieve better effects of treatment it is necessary to improve the coordination of services as provided by the different specialists. The important roles of the patients themselves in the care and management of the disease are emphasized, as well as the roles of the informal caregivers such as a spouse or other family members and friends and the role of patient societies. The possible role of the International Classification of Functioning, Disability and Health (ICF) to improve the communication and facilitate the coordination among health professionals and between patients and health professionals is mentioned. The topics presented in this article may encourage further discussion and research, particularly concerning the effects of the treatments as provided by allied health professionals. Health professionals play an important role in the life of patients with rheumatic disorders, in all the domains of the ICF: body functions and structure, activities (action by an individual) and participation (involvement in a life situation). Health professionals in rheumatology can make the difference in the lives of RA patients and their families.
