Exercise in Patients with Inflammatory Arthritis and Connective Tissue Disease

WITHDRAWN: Therapeutic ultrasound for treating patellofemoral pain syndrome

BACKGROUND

Therapeutic ultrasound is one of several rehabilitation interventions suggested for the management of pain due to patellofemoral knee pain syndrome.

OBJECTIVES

To assess the effectiveness and side effects of ultrasound therapy for treating patellofemoral knee pain syndrome.

SEARCH METHODS

We searched the Cochrane Musculoskeletal Review Group register, Cochrane Field of Physical and Related Therapies register, Cochrane Controlled Trials Register, MEDLINE, EMBASE, HealthSTAR, Sports Discus, CINAHL,and PEDro databases (to December 2000) according to the sensitive search strategy for RCTs designed for the Cochrane Collaboration. The search was complemented with handsearching of the reference lists. Key experts in the area were contacted for any further articles.

SELECTION CRITERIA

All randomized controlled trials (RCTs), controlled clinical trials (CCTs), case-control and cohort studies comparing therapeutic ultrasound against placebo or another active intervention in people with patellofemoral pain syndrome were selected according to an a priori protocol.

DATA COLLECTION AND ANALYSIS

Two reviewers determined the studies to be included based on a priori inclusion criteria. Data were independently extracted by the same two reviewers and checked by a third reviewer (BS) using a previously developed form. The same two reviewers independently assessed the methodological quality of the RCTs and CCTs using a validated scale. The data analysis was performed using Peto odds ratios.

MAIN RESULTS

The search retrieved 85 articles. Of the eight that were potentially relevant, only one RCT, including 53 participants with patellofemoral pain syndrome, was identified for this review. All participants received an exercise program as concurrent therapy. Ultrasound combined with ice massage contrast (n of 13), where n equals the number of participants, was not statistically different from ice massage alone (n = 16) in terms of participant-rated pain relief or quadriceps and hamstring strengthening. In the ultrasound and ice massage group, 46% (6 of 13) reported improved pain relief compared to 31% (4 of 13) in the ice massage alone group. This difference of 15% does not meet international standards for clinically important improvements in osteoarthritis, which is 20%. Side effects were not reported.

AUTHORS' CONCLUSIONS

Ultrasound therapy was not shown to have a clinically important effect on pain relief for people with patellofemoral pain syndrome. These conclusions are limited by the poor reporting of the therapeutic application of the ultrasound and low methodological quality of the one trial included. No conclusions can be drawn concerning the use, or non-use, of ultrasound for treating patellofemoral pain syndrome. More well-designed studies are needed.

Therapeutic ultrasound for osteoarthritis of the knee or hip

BACKGROUND

Osteoarthritis is the most common form of joint disease and the leading cause of pain and physical disability in the elderly. Therapeutic ultrasound is one of several physical therapy modalities suggested for the management of pain and loss of function due to osteoarthritis (OA).

OBJECTIVES

To compare therapeutic ultrasound with sham or no specific intervention in terms of effects on pain and function safety outcomes in patients with knee or hip OA.

SEARCH STRATEGY

We updated the search in CENTRAL, CINAHL, EMBASE, MEDLINE and PEDro up to 23 July 2009, checked conference proceedings, reference lists, and contacted authors.

SELECTION CRITERIA

Studies were included if they were randomised or quasi-randomised controlled trials that compared therapeutic ultrasound with a sham intervention or no intervention in patients with osteoarthritis of the knee or hip.

DATA COLLECTION AND ANALYSIS

Two independent review authors extracted data using standardized forms. Investigators were contacted to obtain missing outcome information. Standardised mean differences (SMDs) were calculated for pain and function, relative risks for safety outcomes. Trials were combined using inverse-variance random-effects meta-analysis.

MAIN RESULTS

Compared to the previous version of the review, four additional trials were identified resulting in the inclusion of five small sized trials in a total of 341 patients with knee OA. No trial included patients with hip OA. Two evaluated pulsed ultrasound, two continuous and one evaluated both pulsed and continuous ultrasound as the active treatment. The methodological quality and the quality of reporting was poor and a high degree of heterogeneity among the trials was revealed for function (88%). For pain, there was an effect in favour of ultrasound therapy, which corresponded to a difference in pain scores between ultrasound and control of -1.2 cm on a 10-cm VAS (95% CI -1.9 to -0.6 cm). For function, we found a trend in favour of ultrasound, which corresponded to a difference in function scores of -1.3 units on a standardised WOMAC disability scale ranging from 0 to 10 (95% CI -3.0 to 0.3). Safety was evaluated in two trials including up to 136 patients; no adverse event, serious adverse event or withdrawals due to adverse events occurred in either trial.

AUTHORS' CONCLUSIONS

In contrast to the previous version of this review, our results suggest that therapeutic ultrasound may be beneficial for patients with osteoarthritis of the knee. Because of the low quality of the evidence, we are uncertain about the magnitude of the effects on pain relief and function, however. Therapeutic ultrasound is widely used for its potential benefits on both knee pain and function, which may be clinically relevant. Appropriately designed trials of adequate power are therefore warranted.

Aquatic therapy: scientific foundations and clinical rehabilitation applications

The aquatic environment has broad rehabilitative potential, extending from the treatment of acute injuries through health maintenance in the face of chronic diseases, yet it remains an underused modality. There is an extensive research base supporting aquatic therapy, both within the basic science literature and clinical literature. This article describes the many physiologic changes that occur during immersion as applied to a range of common rehabilitative issues and problems. Because of its wide margin of therapeutic safety and clinical adaptability, aquatic therapy is a very useful tool in the rehabilitative toolbox. Through a better understanding of the applied physiology, the practitioner may structure appropriate therapeutic programs for a diverse patient population.

Prevalence and treatment patterns of physical impairments in patients with metastatic breast cancer

PURPOSE

Physical impairments cause profound functional declines in patients with cancer. Although common rehabilitation measures can address many impairments, the extent of their delivery is unknown. We studied these issues by quantifying physical impairments in patients with metastatic breast cancer and by assessing how they are addressed.

PATIENTS AND METHODS

A consecutive sample of 163 community-dwelling patients with metastatic breast cancer was stratified by Karnofsky performance score and administered the Medical Outcomes Study Physical Function Subscale and the Older Americans Resource Study Activities of Daily Living subscales. Cancer-related physical impairments were identified through a physical examination, the 6-Minute Walk Test, and the Functional Independence Measure Mobility Subscale. Patients were questioned regarding the nature, type, and setting of treatments for impairments. Physical rehabilitation needs were determined through a consensus process involving physiatrists and physical/occupational therapists specializing in cancer.

RESULTS

Ninety-two percent of patients (150 of 163) had at least one physical impairment. Among 530 identified impairments, 484 (92%) required a physical rehabilitation intervention and 469 (88%) required physical therapy (PT) and/or occupational therapy (OT). Only 30% of impairments requiring rehabilitation services and 21% of those requiring PT/OT received treatment. Impairments detected during hospitalization were overwhelmingly more likely to receive a rehabilitation intervention (odds ratio [OR] = 87.9; 95% CI, 28.5 to 271.4), and PT/OT (OR = 558.8; 95% CI, 187.0 to 1,669.6). Low socioeconomic and minority status were significantly associated with nontreatment.

CONCLUSION

Remediable physical impairments were prevalent and poorly addressed among patients with metastatic breast cancer, drastically so in the outpatient setting. Undertreatment was particularly prominent among minority and socioeconomically disadvantaged groups.

WITHDRAWN: Dynamic exercise therapy for treating rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting the musculoskeletal system. Inflammation of the joints and tendons results in pain, swelling and restricted movement, eventually leading to radiological changes and deformities. Exercise therapy is considered to be an important cornerstone of the treatment of RA in all stages of the disease.

OBJECTIVES

To assess the effects of dynamic exercise therapy in improving joint mobility, muscle strength, aerobic capacity and daily functioning in patients with rheumatoid arthritis (RA). In addition, possible unwanted effects such as an increase in pain, disease activity and radiological progression were studied.

SEARCH STRATEGY

We searched the Cochrane Musculoskeletal trials register, the Cochrane Controlled trials Register, MEDLINE, EMBASE and SCISEARCH databases up to May 1997 in order to controlled trials on the effect of exercise therapy.

SELECTION CRITERIA

Randomized trials on the effect of dynamic exercise therapy in RA patients with an exercise program fulfilling the following criteria: a) intensity level such that heart rates exceeded 60% of maximal heart rate during at least 20 minutes, b) exercise frequency of two sessions per week, and c) duration of intervention of greater than six weeks

DATA COLLECTION AND ANALYSIS

Two blinded reviewers independently selected eligible studies, rated the methodological quality and extracted data.

MAIN RESULTS

Six out of 30 identified controlled trials met the inclusion criteria. Four of the six included studies fulfilled at least seven out of 10 methodological criteria. Due to heterogeneity in outcome measures, data could not be pooled. The results suggest that dynamic exercise therapy is effective at increasing aerobic capacity and muscle strength. No detrimental effects on disease activity and pain were observed. The effects of dynamic exercise therapy on functional ability and radiological progression are unclear.

AUTHORS' CONCLUSIONS

The results suggest that dynamic exercise therapy is effective at increasing aerobic capacity and muscle strength. No detrimental effects on disease activity and pain were observed. The effects of dynamic exercise therapy on functional ability and radiological progression are unclear. Dynamic exercise therapy has a positive effect on physical capacity. Research on the long-term effect of dynamic exercise therapy on radiological progression and functional ability is needed.

Exercise may decrease further destruction in the adult haemophilic joint

The effect of exercise on adult haemophilic joints was investigated. Forty-six subjects with existing joint disease were evaluated and range of motion (ROM) in joints was measured. The effect of exercise of large joint ROM in haemophilia was evaluated by comparing the ranges of motion in subjects who exercised at least three times weekly against those subjects who did not exercise. The exercise group showed improvement in the majority of joint ranges of motion compared with the non-exercise group (P = 0.003). Thus regular exercise may help reduce further destruction in haemophilic joints by strengthening muscle ligaments and tendons surrounding the joint thereby protecting them from damage caused by recurrent haemarthrotic events.

A randomized two-year study of the effects of dynamic strength training on muscle strength, disease activity, functional capacity, and bone mineral density in early rheumatoid arthritis

OBJECTIVE

To evaluate the impact of a 2-year program of strength training on muscle strength, bone mineral density (BMD), physical function, joint damage, and disease activity in patients with recent-onset (<2 years) rheumatoid arthritis (RA).

METHODS

In this prospective trial, 70 RA patients were randomly assigned to perform either strength training (all major muscle groups of the lower and upper extremities and trunk, with loads of 50-70% of repetition maximum) or range of motion exercises (without resistance) twice a week; all were encouraged to engage in recreational activities 2-3 times a week. All patients completed training diaries (evaluated bi-monthly) and were examined at 6-month intervals. All were treated with medications to achieve disease remission. Maximum strength of the knee extensors, trunk flexors and extensors, and grip strength was measured with dynamometers. BMD was measured at the femoral neck and lumbar spine by dual x-ray densitometry. Disease activity was determined by the Disease Activity Score, the extent of joint damage by the Larsen score, and functional capacity by the Health Assessment Questionnaire (HAQ); walking speed was also measured.

RESULTS

Sixty-two patients (31 per group) completed the study. Strength training compliance averaged 1.4-1.5 times/week. The maximum strength of all muscle groups examined increased significantly (19-59%) in the strength-training group, with statistically significant improvements in clinical disease activity parameters, HAQ scores, and walking speed. While muscle strength, disease activity parameters, and physical function also improved significantly in the control group, the changes were not as great as those in the strength-training group. BMD in the femoral neck and spine increased by a mean +/- SD of 0.51 +/- 1.64% and by 1.17 +/- 5.34%, respectively, in the strength-training group, but decreased by 0.70 +/- 2.25% and 0.91 +/- 4.07% in the controls. Femoral neck BMD in the 17 patients with high initial disease activity (and subsequent use of oral glucocorticoids) remained constantly at a statistically significantly lower level than that in the other 45 patients.

CONCLUSION

Regular dynamic strength training combined with endurance-type physical activities improves muscle strength and physical function, but not BMD, in patients with early RA, without detrimental effects on disease activity.

Rheumatologist-patient communication about exercise and physical therapy in the management of rheumatoid arthritis

OBJECTIVE

Little is known about the features and role of exercise discussions between rheumatologists and patients. The goals of this study were to: 1) describe rheumatologists' and patients' attitudes and beliefs regarding exercise and physical therapy for rheumatoid arthritis (RA); 2) describe frequency and length of exercise discussions; 3) determine the accuracy of recall for exercise discussions; and 4) assess the influence of attitudes regarding exercise on communication about exercise.

METHODS

Goals 1-3 were addressed with analysis of baseline questionnaires and audiotaped encounters. The influence of attitudes and beliefs regarding exercise on the frequency and length of exercise discussions was assessed prospectively. Patients and rheumatologists were enrolled from a large tertiary care institution. Clinical encounters were audiotaped, transcribed, coded, and analyzed to identify specific characteristics of the exercise discussions.

RESULTS

One hundred thirty-two patients and 25 rheumatologists participated in the study. Rheumatologists and patients discussed exercise in 53% of the encounters. Rheumatologists' beliefs regarding the usefulness of exercise for RA varied, with the least positive beliefs being reported for aerobic exercise. Exercise discussions were more likely to occur if the patient was currently exercising, odds ratio (OR) = 2.4; 95% confidence interval (CI) (1.2-4.9), and when the rheumatologist believed aerobic exercises were useful in managing RA, OR = 1.4; 95% CI (1.1-1.9). Current exercise behavior was associated with patients' positive attitude toward exercise (chi 2 1 = 8.4; P = 0.004) and perceived social support for exercise (chi 2 1 = 4.5; P = 0.04). When rheumatologists initiated exercise discussions, there was nearly twice as much discussion (beta = -8.4; P = 0.001).

CONCLUSIONS

Exercise talk was influenced by patients' and rheumatologists' beliefs and attitudes regarding the effectiveness of exercise and physical therapy in managing RA, patient experience with exercise, and by characteristics of the rheumatologist.

Classification and treatment of the juvenile idiopathic inflammatory myopathies

This article reviews the current status of the classification and treatment of the juvenile idiopathic inflammatory myopathies. The intent of classification is to define homogeneous groups that share similar clinical features, disease courses, and responses to therapy. The classification scheme proposed includes clinicopathologic subsets, serologic subjects based on the presence of myositis-specific and myositis-associated autoantibodies, and environmental triggers of myositis. Juvenile dermatomyositis is the most common and widely recognized of these disorders. The second part reviews the history of treatment of juvenile dermatomyositis and discusses agents to consider for patients with refractory disease, unacceptable steroid toxicity, or poor prognostic factors.

Osteoarthritis: how to make exercise part of your treatment plan

The idea of exercising with swollen, painful joints and weakened muscles may seem counterintuitive. But increasingly research shows that the vicious cycle of immobility and dependence initiated by osteoarthritis can be interrupted by making exercise part of therapy. A well-designed program of aerobic and resistance training and whole-body flexibility and joint mobility exercise should join other interventions such as weight loss, medication, physical therapy, joint protection, and surgery to improve symptoms and reduce the impact of osteoarthritis on patients' lives.

This article discusses treatment and outcome in rheumatoid arthritis, musculoskeletal involvement in human immunodeficiency virus infection, scleroderma, systemic lupus erythematosus, and intraarticular injection of corticosteroids.

Determinants of Exercise Level in the Sedentary versus Underactive Older Adult: Implications for Physical Activity Program Development

This investigation identified demographic and health-related characteristics of 1,877 sedentary, underactive, and regularly active individuals aged 50 to 65 randomly sampled from a northern California city. Physiological and psychosocial information was available in greater detail for a subsample (n = 327) of sedentary and underactive persons who were subsequently enrolled in a randomized, controlled, clinical trial (SSHIP). Results suggested that unmarried men, women reporting poor health, and smokers were most likely to be completely sedentary. Sedentary and underactive individuals responded differently to two recruitment strategies designed to attract participants into SSHIP. In addition, the initially sedentary participants had significantly lower adherence rates across the 1-year exercise trial compared to the initially underactive regardless of either the format or intensity of the program. These data underscore the utility of differentiating between levels of less-than-optimal physical activity in formulating campaigns promoting physical activity as well as designing exercise interventions.

Elderly rheumatoid arthritis patients on steroid treatment tolerate physical training without an increase in disease activity

The effects of physical training on elderly, fragile patients with rheumatoid arthritis (RA) who are on low-dose steroids were investigated. The controlled study included 24 patients who had been treated with low-dose steroids for 2 years. Each patient was assigned either to a treatment group receiving training or to an untrained control group. The training took place over a 3-month period and was based on a protocol using progressive interval training consisting of bicycle exercises, heel lifts, and step-climbing. The exercises were performed twice weekly for 45 minutes. Comparison of the two groups showed that disease activity did not increase in the trained group and that fewer, but not significantly fewer, swollen joints were observed in this group (p = 0.06). No significant changes were noticed in erythrocyte sedimentation rate, tender joints, or morning stiffness. The work capacity of the trained patients were doubled and the numbers of repetitions increased 76%. Individually adapted exercise programs can therefore be recommended for elderly rheumatoid arthritis patients on steroid treatment.

Exercise capacity and hemodynamics in systemic lupus erythematosus: a Doppler echocardiographic exercise study

Although pulmonary hypertension is a well-described manifestation of systemic lupus erythematosus, there are few data regarding the pulmonary artery pressure response to exercise. We hypothesized that exercise capacity was reduced and that the pulmonary artery pressure response to exercise was abnormal in patients with systemic lupus erythematosus. To test these hypotheses, we performed Doppler exercise echocardiography in 18 patients with lupus and 10 normal control subjects. Exercise duration was significantly reduced in the patients with lupus (8.1 vs 14.4 minutes for control subjects, p < or = 0.001). Pulmonary artery pressure was significantly higher in the patients with lupus at rest and during the first two stages of exercise (p < 0.05). Cardiac indexes at rest were similar in the two groups, suggesting that increased pulmonary vascular resistance was the mechanism for the higher pulmonary pressure we observed. We conclude that abnormal exercise hemodynamics may contribute to reduced exercise capacity in patients with lupus.

Optimizing Exercise Programs for Arthritis Patients

In brief As part of a comprehensive brief treatment plan, exercise can decrease pain and improve function in people who have rheumatoid arthritis or osteoarthritis. The physician must prescribe an individualized, realistic, and enjoyable exercise program that helps the affected joints and builds fitness. Well-tailored recommendations can also help maximize patient compliance. The physician must also provide appropriate follow-up care, adjusting the exercise program and medications as needed.
