Abstract: 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.

Abstract: 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.

Abstract: Non-pharmacological treatment modalities are often recommended, prescribed and used in addition to drug treatment in patients with rheumatoid arthritis (RA). This article provides a review of the literature on their effectiveness. Currently, a considerable number of systematic reviews summarising the available studies for non-drug care interventions in RA are available. The evidence of effectiveness varies among the different non-pharmacological modalities, with relatively strong support for exercise and self-management interventions, and modest support for joint protection programmes, specific orthoses and comprehensive care interventions. Overall, the evidence for effectiveness of massage and electro-physical modalities is absent or weak. In general, few studies in patients with early RA, studies comparing different attributes of non-pharmacological modalities or comprehensive care models and economic evaluations have been performed, so that the optimal timing, intensity, duration and mode of delivery often remain unclear. The results of this review indicate a need for further investigation into the most clinically and cost-effective strategies to deliver individual non-pharmacological treatment modalities as well as comprehensive arthritis service delivery models for RA patients in different stages of the disease.

Abstract: PURPOSE OF REVIEW: Patients with rheumatoid arthritis benefit from long-term moderate or high-intensity exercises. Moderate or high-intensity exercises were found to improve aerobic capacity, muscle strength, functional ability, and psychological well-being, and slow the age-related and sex-related decrease in bone mineral density of the hip. Despite these positive findings, there is also concern about its risks. Studies on the effects of exercise on disease activity and joint damage are reviewed. RECENT FINDINGS: Studies on the effects of moderate or high-intensity exercise in rheumatoid arthritis demonstrate either decreased or stable disease activity. From the few available studies that address exercise and radiologic progression of the small joints, results indicate that exercises are safe for the joints of hands and feet. However, a recent study suggests caution in prescribing long-term high-intensity weight-bearing exercises to patients who have significant radiologic damage of large joints, as some patients might develop additional damage. SUMMARY: Moderate or high-intensity weight-bearing exercises are safe with respect to disease activity and radiologic damage of the hands and feet. In the absence of sufficient data on exercise and radiologic progression of the large joints, patients with significant radiologic damage of the large joints should not be encouraged to participate in moderate to high-intensity weight-bearing exercise unless individualized to protect affected joints. A broader dissemination of the effectiveness and safety of moderate and high-intensity exercise for patients with rheumatoid arthritis is needed among rheumatologists, physical therapists, and patients.

Abstract: PURPOSE OF REVIEW: Comprehensive rehabilitation, involving a team of health professionals from various disciplines, is widely used as an adjunct to pharmacological and surgical treatment in patients with rheumatoid arthritis (RA). Studies on the effectiveness and costs of such programs, as well as on developments regarding outcome measures and quality improvement in this particular field are reviewed. RECENT FINDINGS: Recent studies confirm that defined day patient multidisciplinary programs are equally effective as inpatient team care programs. It appears that similar effects, at lower costs, may be achieved by clinical nurse specialists coordinating multidisciplinary care in an outpatient setting. With respect to outcome measures on effectiveness of multidisciplinary team care, the use of function-specific and patient-oriented outcome measures is advocated. Moreover, the use of tools and procedures to enhance the role of the patient in the team care process and communication among health professionals may yield important leads for the improvement of the effectiveness and quality of multidisciplinary team care. SUMMARY: Comprehensive inpatient and day patient programs prove to be equally effective in patients with rheumatoid arthritis, while the employment of alternative forms of comprehensive care, such as care coordinated by a clinical nurse specialist, is promising. With respect to future research, challenges are related to the development and selection of adequate outcome measures, the enhancement of mutual communication, and a further definition and extension of the role of the patient in the team care process.

Abstract: Rehabilitation, as an adjunct to pharmacological and surgical therapies in patients with rheumatoid arthritis (RA), aims to minimize the consequences of the disease. For a systematic assessment of the consequences of disease, an appropriate definition and evaluation of the goals of therapy and interventions, and an active partnership with the patient, a structured approach to rehabilitation management is needed.Despite widespread positive clinical experience with rehabilitative interventions, the scientific evidence of their effectiveness is, in general, scanty, owing to a lack of studies with sufficient methodological quality. Further well-designed clinical studies are warranted with respect to several interventions where evidence is falling short.

Abstract: OBJECTIVE: To investigate whether a high-intensity exercise program accelerates the rate of radiologic damage of the large joints in predefined subgroups of patients with rheumatoid arthritis. METHODS: The data of 277 participants in a 2-year randomized controlled trial, comparing the effects of high-intensity exercises with usual care, were used. Linear regression analysis was used to test which predefined variables at baseline (age, disease duration, disease activity, physical capacity, functional ability, joint damage) modified the effect of high-intensity exercise on the progression of radiologic damage of the large joints over 24 months. RESULTS: Baseline radiologic joint damage was the only variable associated with the effect of high-intensity exercise on joint damage progression in large joints. In a subgroup of 218 patients with no or little joint damage (defined as Larsen score < or = 5; 80% of our study population) the proportions of patients with an increase in joint damage were similar for the exercise and usual-care group (35% versus 36%, risk ratio [RR] 1.0 [0.7-1.4]; P = not significant), whereas, in a subgroup of 59 patients who already had extensive damage of large joints (defined as Larsen score >5) the proportion was significantly higher in the exercise group (85% versus 48%, RR 1.8 [1.2-2.6]; P < 0.05). CONCLUSION: High-intensity weight-bearing exercises appear to accelerate joint damage progression in patients with preexisting extensive damage. Patients with extensive large joint damage should, therefore, be advised to refrain from activities excessively loading the damaged joints.

Abstract: OBJECTIVE: To estimate the cost utility and cost effectiveness of long-term, high-intensity exercise classes compared with usual care in rheumatoid arthritis (RA) patients. METHODS: RA patients (n = 300) were randomly assigned to either exercise classes or UC; followup lasted for 2 years. Outcome measures were quality-adjusted life years (QALYs) according to the EuroQol (EQ-5D), Short Form 6D (SF-6D), and a transformed visual analog scale (VAS) rating personal health; functional ability according to the Health Assessment Questionnaire (HAQ) and McMaster Toronto Arthritis Patient Preference Interview (MACTAR); and societal costs. RESULTS: QALYs in both randomization groups were similar according to the EQ-5D and SF-6D, but were in favor of usual care according to the VAS (annual difference 0.037 QALY; 95% confidence interval [95% CI] 0.002, 0.069). Functional ability was similar according to the HAQ, but in favor of the exercise classes according to the MACTAR (annual difference 2.9 QALY; 95% CI 0.9, 4.9). Annual medical costs of the exercise program were estimated at 780 per participating patient (1 approximately $1.05). The increase per patient in total medical costs of physical therapy was estimated at 430 (95% CI 318, 577), and the increase in total societal costs at 602 (95% CI -490, 1,664). For societal willingness-to-pay equal to 50,000 per QALY, usual care had better cost utility than exercise classes, and significantly so according to the VAS. CONCLUSION: From a societal perspective and without taking possible preventive health effects into account, long-term, high-intensity exercise classes provide insufficient improvement in the valuation of health to justify the additional costs.

Abstract: OBJECTIVE: To investigate the effect of long term high intensity weightbearing exercises on radiological damage of the joints of the hands and feet in patients with rheumatoid arthritis (RA). METHODS: Data of the 281 completers of a 2 year randomised controlled trial comparing the effects of usual care physical therapy (UC) with high intensity weightbearing exercises were analysed for the rate of radiological joint damage (Larsen score) of the hands and feet. Potential determinants of outcome were defined: disease activity, use of drugs, change in physical capacity and in bone mineral density, and attendance rate at exercise sessions. RESULTS: After 2 years, the 136 participants in high intensity weightbearing exercises developed significantly less radiological damage than the 145 participants in UC. The mean (SD) increase in damage was 3.5 (7.9) in the exercise group and 5.7 (10.2) in the UC group, p = 0.045. Separate analysis of the damage to the hands and feet suggests that this difference in rate of increase of damage is more pronounced in the joints of the feet than in the hands. The rate of damage was independently associated with less disease activity, less frequent use of glucocorticoids, and with an improvement in aerobic fitness. CONCLUSION: The progression of radiological joint damage of the hands and feet in patients with RA is not increased by long term high intensity weightbearing exercises. These exercises may have a protective effect on the joints of the feet.

Abstract: OBJECTIVE: To investigate the generalizability of the results of a randomized controlled trial on the effectiveness of long-term, high-intensity exercises in the rheumatoid arthritis patients in training (RAPIT) trial by comparing the characteristics of the participants with the nonparticipants. METHODS: Participants and nonparticipants were mailed questionnaires on sociodemographic characteristics, health status, reasons not to participate, and attitudes toward intensive exercise. RESULTS: The questionnaires from 892 (75%) nonparticipants and 299 (97%) participants were collected. The nonparticipants were slightly older, more often male, and had longer disease duration than the participants. The nonparticipants perceived their disease as more serious, used fewer disease-modifying antirheumatic drugs, had a lower level of education, and a more negative attitude toward intensive exercise. CONCLUSION: The results of the RAPIT trial might not be generalizable to the entire target population. To promote participation in long-term, high-intensity exercises, health professionals should more actively discuss the potential benefits of exercise with their RA patients while taking into consideration specific factors related to participation.

Abstract: OBJECTIVE: Patients with rheumatoid arthritis (RA) are more at risk for the development of osteoporosis and osteoporotic fractures than are their healthy peers. In this randomized, controlled, multicenter trial, the effectiveness of a 2-year high-intensity weight-bearing exercise program (the Rheumatoid-Arthritis-Patients-In-Training [RAPIT] program) on bone mineral density (BMD) was compared with usual care physical therapy, and the exercise modalities associated with changes in BMD were determined. METHODS: Three hundred nine patients with RA were assigned to an intervention group, either the RAPIT program or usual care physical therapy. The primary end points were BMD of the hip and spine. The exercise modalities examined were aerobic fitness, muscle strength, and, as a surrogate for those effects not directly measured by the RAPIT program, attendance rate. RESULTS: The data on the 136 RAPIT participants and 145 usual care participants who completed the study were analyzed. The mean rate of decrease in hip BMD, but not in lumbar spine BMD, was smaller in patients participating in the RAPIT program when compared with that in the usual care group, with a mean decrease of 1.6% (95% confidence interval [95% CI] 0.8-2.5) over the first year and 0.5% (95% CI 1.1-2.0) over the second year. The change in hip BMD was significantly and independently associated with changes in both muscle strength (multivariate odds ratio [OR] 1.75, 95% CI 1.07-2.86) and aerobic fitness (OR 1.79, 95% CI 1.10-2.90), but not with the attendance rate (OR 1.00, 95% CI 0.99-1.00). CONCLUSION: A long-term high-intensity weight-bearing exercise program for RA patients is effective in slowing down the loss of BMD at the hip. The exercise modalities associated with this effect are muscle strength and aerobic fitness.

Abstract: OBJECTIVE: To evaluate adherence and satisfaction of patients with rheumatoid arthritis (RA) in a long-term intensive dynamic exercise program. METHODS: A total of 146 RA patients started an intensive (strength and endurance training for 75 minutes, twice a week, for 2 years) exercise program (Rheumatoid Arthritis Patients In Training) aimed at improving physical fitness. Program attendance and satisfaction were examined. Additional assessments at baseline were done to find possible predictors of attendance. RESULTS: Median (interquartile range) age and disease duration of the patients were 54 (45-61) and 5 (3-10) years, respectively. After 2 years, 118 (81%) patients still participated in an exercise class. The median attendance rate of all patients was 74%. Low attendance was weakly associated with high disease activity, low functional ability, and low quality of life at baseline but not with the severity of joint damage at baseline. At the end, 78% of all participants would (strongly) recommend the program to other RA patients. CONCLUSION: Adherence and satisfaction of RA patients with an intensive dynamic exercise program over a prolonged time can be high. Disease severity parameters do not strongly predict the compliance of participants in an intensive exercise program.

Abstract: OBJECTIVE: There are insufficient data on the effects of long-term intensive exercise in patients with rheumatoid arthritis (RA). We undertook this randomized, controlled, multicenter trial to compare the effectiveness and safety of a 2-year intensive exercise program (Rheumatoid Arthritis Patients In Training [RAPIT]) with those of physical therapy (termed usual care [UC]). METHODS: Three hundred nine RA patients were assigned to either the RAPIT program or UC. The primary end points were functional ability (assessed by the McMaster Toronto Arthritis [MACTAR] Patient Preference Disability Questionnaire and the Health Assessment Questionnaire [HAQ]) and the effects on radiographic progression in large joints. Secondary end points concerned emotional status and disease activity. RESULTS: After 2 years, participants in the RAPIT program showed greater improvement in functional ability than participants in UC. The mean difference in change of the MACTAR Questionnaire score was 2.6 (95% confidence interval [95% CI] 0.1, 5.2) over the first year and 3.1 (95% CI 0.7, 5.5) over the second year. After 2 years, the mean difference in change of the HAQ score was -0.09 (95% CI -0.18, -0.01). The median radiographic damage of the large joints did not increase in either group. In both groups, participants with considerable baseline damage showed slightly more progression in damage, and this was more obvious in the RAPIT group. The RAPIT program proved to be effective in improving emotional status. No detrimental effects on disease activity were found. CONCLUSION: A long-term high-intensity exercise program is more effective than UC in improving functional ability of RA patients. Intensive exercise does not increase radiographic damage of the large joints, except possibly in patients with considerable baseline damage of the large joints.

Abstract: OBJECTIVES: To develop and validate a questionnaire for measuring satisfaction with different forms of complex multidisciplinary care in patients with rheumatoid arthritis (RA). METHODS: The satisfaction questionnaire (score range 0-100) comprised 28 items covering 11 domains. Together with a visual analog scale (VAS, range 0-100) on overall satisfaction, the questionnaire was applied in 210 RA patients who participated in a randomized trial comparing 3 types of multidisciplinary care. RESULTS: The questionnaire was returned by 174 patients (83%). The questionnaire and VAS scores in the total group were 75 (SD 12) and 83 (SD 20), respectively. Reliability analysis showed Cronbach's alpha of the questionnaire was 0.91. Spearman's correlation coefficient between the satisfaction questionnaire score and VAS score was 0.58 (P < 0.01). Mean total satisfaction questionnaire scores were 72 (SD 9), 76 (SD 14), and 78 (SD 11), in the nurse specialist, inpatient and day patient groups, respectively (nurse specialist versus day patient, P = 0.004). Significant differences between nurse specialist and day patients were seen in the following domains: waiting time during the treatment, autonomy, coordination, non-financial access, and quality of general information (all P < 0.05). CONCLUSION: Overall, patients were highly satisfied with the multidisciplinary care they received. Major differences regarding the organization of care were reflected in the results of the questionnaire scores. The satisfaction questionnaire appears to be a useful instrument for measuring satisfaction with complex multidisciplinary care in RA patients.

Abstract: OBJECTIVE: To assess the relative cost effectiveness of clinical nurse specialist care, inpatient team care, and day patient team care. METHODS: Incremental cost effectiveness analysis and cost utility analysis, alongside a prospective randomised controlled trial with two year follow up. Included were patients with rheumatoid arthritis (RA) with increasing difficulty in performing activities of daily living over the previous six weeks. Quality of life and utility were assessed by the Rheumatoid Arthritis Quality of Life questionnaire, the Short Form-6D, a transformed rating scale, and the time tradeoff. A cost-price analysis was conducted to estimate the costs of inpatient and day patient hospitalisations. Other healthcare and non-healthcare costs were estimated from cost questionnaires. RESULTS: 210 patients with RA (75% female, median age 59 years) were included. Aggregated over the two year follow up period, no significant differences were found on the quality of life and utility instruments. The costs of the initial treatment were estimated at euro 200 for clinical nurse specialist care, euro 5000 for inpatient team care, and euro 4100 for day patient team care. Other healthcare costs and non-healthcare costs were not significantly different. The total societal costs did not differ significantly between inpatients and day patients, but were significantly lower for the clinical nurse specialist patients by at least euro 5400. CONCLUSIONS: Compared with inpatient and day patient team care, clinical nurse specialist care was shown to provide equivalent quality of life and utility, at lower costs. Therefore, for patients with health conditions that allow for any of the three types of care, the preferred treatment from a health-economic perspective is the care provided by the clinical nurse specialist.

Abstract: OBJECTIVES: To compare in a randomized, controlled trial the clinical effectiveness of care delivered by a clinical nurse specialist, inpatient team care, and day patient team care in patients with rheumatoid arthritis (RA) who have increasing functional limitations. METHODS: Between December 1996 and January 1999, 210 patients with RA were recruited in the outpatient clinic of the rheumatology department of 6 academic and nonacademic hospitals. Clinical assessments recorded on study entry and weeks 6, 12, 26, and 52 included the Health Assessment Questionnaire (HAQ) and the McMaster Toronto Arthritis Patient Preference Disability Questionnaire as primary outcome measures, and the RAND-36 Item Health Survey, the Rheumatoid Arthritis Quality of Life questionnaire, the Health Utility Rating Scale, and the Disease Activity Score as secondary outcome measures. Patient satisfaction with care was measured on a visual analog scale in week 6 in all 3 groups and again in week 12 in the nurse specialist group. RESULTS: Within all 3 groups, functional status, quality of life, health utility, and disease activity improved significantly over time (P < 0.05). However, a comparison of clinical outcome among the 3 groups and a comparison between the nurse specialist group and the inpatient and day patient care groups together did not show any sustained significant differences. Subgroup analysis showed that age had a significant impact on differences between the 3 treatment groups with respect to functional outcome as measured with the HAQ (P < 0.001). With increasing age, the most favorable outcome shifted from care provided by a clinical nurse specialist and inpatient care to day patient care. Patients' satisfaction with care was significantly lower in the nurse specialist group than in the inpatient and day patient care groups (P < 0.001). CONCLUSION: Care provided by a clinical nurse specialist appears to have a similar clinical outcome in comparison with inpatient and day patient team care. Although all patients were highly satisfied with multidisciplinary care, patients who received care provided by a clinical nurse specialist were slightly less satisfied than those who received inpatient or day patient team care. Age appeared to be the only factor related to differences in functional outcome between the 3 treatment groups. The choice of management strategy may, apart from age, further be dependent on the availability of facilities, the preferences of patients and health care providers, and economic considerations.

Abstract: OBJECTIVE: To examine further the usefulness of a 30-item disease-specific quality of life (QoL) questionnaire in patients with rheumatoid arthritis (RA). METHODS: The Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire was applied to two groups consisting of 210 and 300 patients with RA, one group with increasing difficulty in performing activities of daily living and one group with stable disease. The associations between the RAQoL and measures of utility, QoL, functional status and disease activity were evaluated. Factor analysis was carried out to investigate if one or more QoL dimensions could be distinguished within this questionnaire. RESULTS: Similar results regarding the association between the RAQoL and different sets of outcome measures were found in the two groups of patients. Regression analysis showed that about 75% of the variance of the RAQoL could be explained with variables of QoL, functional status and disease activity. Physical contact could be distinguished as a separate dimension within the RAQoL, in addition to the dimensions mobility/energy, self-care and mood/emotion. CONCLUSION: The RAQoL is a valid instrument for measuring QoL in different populations of patients with RA. Physical contact, a dimension that is not covered by other common instruments in RA, could be distinguished as a separate dimension within the questionnaire.

Abstract: OBJECTIVES: The reliability and discriminative capacity of hand function tests were studied in order to obtain tests suitable for the evaluation of local treatment of an arthritic metacarpophalangeal (MCP) joint. METHODS: To assess reliability, hand function tests were measured twice without local treatment of the MCP in 25 patients with rheumatoid arthritis (RA). The discriminative capacity of the hand function tests with respect to the results of intra-articular corticosteroid injection was assessed in 28 RA patients with synovitis of an MCP joint. Thereafter, a randomized, observer-blind treatment study was performed in 21 RA patients with synovitis of an MCP joint; 10 of the patients were treated. Results/Conclusions. This study showed that the efficacy of treatment of an MCP joint can be measured by several reliable and discriminative parameters: passive flexion, the Ritchie pain score, swelling, the Arthritis Impact Measurements Scales question about buttoning clothes, and visual analogue scale questions about the activity of the disease and swelling of the joint.

Abstract: The aims of this study were to describe rheumatoid arthritis patients' compliance with continued exercise after participation in a 2-year supervised high-intensity exercise program and to investigate if the initially achieved effectiveness and safety were sustained. Data were gathered by follow-up of the participants who completed the 2-year high-intensity intervention in a randomized controlled trial (Rheumatoid Arthritis Patient In Training study). Eighteen months thereafter, measurements of compliance, aerobic capacity, muscle strength, functional ability, disease activity, and radiological damage of the large joints were performed. Seventy-one patients were available for follow-up at 18 months, of whom 60 (84%) were still exercising (exercise group: EG), with average similar intensity but at a lower frequency as the initial intervention. Eleven patients (16%) reported low intensity or no exercises (no-exercise group: no-EG). Patients in the EG had better aerobic fitness and functional ability, lower disease activity, and higher attendance rate after the initial 2-year intervention. At follow-up, both groups showed a deterioration of aerobic fitness and only patients in the EG were able to behold their muscle strength gains. Functional ability, gained during the previous participation in high-intensity exercises, remained stable in both groups. Importantly, no detrimental effects on disease activity or radiological damage of the large joints were found in either group. In conclusion, the majority of the patients who participated in the 24-month high-intensity exercise program continued exercising in the ensuing 18 months. In contrast to those who did not continue exercising, they were able to preserve their gains in muscle strength without increased disease activity or progression of radiological damage.

Abstract: In a randomized controlled trial, Adams et al. compared the effectiveness of static resting wrist splints plus occupational therapy with occupational therapy alone in 120 patients with early rheumatoid arthritis. Self-reported adherence with splint wear was moderate, with 24.5% of patients reporting that they had never worn the splints over the 12-month study period. Except for a small benefit of resting splints in the occurrence, but not the duration, of hand morning stiffness, there were no significant differences in structural impairment and functional hand ability outcomes between the control and splint groups. The findings of this trial are in line with the negative outcomes of earlier studies of static resting wrist splints in patients with longer disease duration. The currently available data suggest, therefore, that resting wrist splints might not be an effective routine treatment for patients with rheumatoid arthritis.

Abstract: OBJECTIVE: To investigate the internal consistency, validity and responsiveness of the Rehabilitation Activities Profile (RAP; a rehabilitation tool structuring the multidisciplinary team care process) in patients with rheumatoid arthritis. METHODS: In 85 rheumatoid arthritis patients admitted to a rheumatology clinic the RAP was applied at admission, at discharge, and six weeks thereafter. Additional assessments included measures of physical and psychological functioning, disease activity and quality of life. The internal consistency of the RAP was determined with Cronbach's alpha. Associations between the RAP and other outcome measures were determined by Spearman rank correlation coefficients. Responsiveness measures included the standardized response mean (SRM), effect size (ES) and responsiveness ratio (RR). RESULTS: Cronbach's alpha of the RAP total score was 0.78. The RAP total score correlated significantly with all other outcome measures. The mean RAP total score improved from 15.2 to 13.2 at discharge (change -2.0; 95% confidence interval (CI) -3.4 to -0.7) and to 11.5 (change -3.7; 95% CI -3.9 to -1.5) six weeks thereafter. The responsiveness of the RAP total score was low (standardized response mean -0.34, effect size -0.30) to high (responsiveness ratio -0.87) at discharge and moderate (standardized response mean -0.54, effect size -0.55) to high (responsiveness ratio -1.56) six weeks thereafter.CONCLUSIONS: The RAP appeared to be an internally consistent, valid and responsive measure to reflect limitations on the level of activities and participation in patients with rheumatoid arthritis admitted for multidisciplinary team care.

Abstract: We describe the usage of various assistive devices and identify factors associated with usage in patients with rheumatoid arthritis (RA). A cross-sectional, multicentre study was performed in three outpatient rheumatology clinics in the Netherlands. Two hundred forty patients with RA participated in the study. The main measures were questionnaires and a semi-structured interview regarding the possession and usage of 21 common assistive devices in the ISO9999 categories orthopaedic footwear, personal care, mobility, household and adaptations for housing. Potential factors associated with usage included sociodemographic variables, health status, quality of life, coping strategies, self-efficacy, outcome expectations and satisfaction. Out of 240 patients, 213 (89%) had one or more assistive devices in possession (median number of devices 3.0, interquartile range 3.0). The proportions of patients never using a device in possession varied between 8% for orthopaedic insoles and 23% for grab bars. The main factors related to usage varied among categories, but common determinants were a specific impairment or disability, satisfaction with the device or related services, self-efficacy and the number of devices in possession. In conclusion, in patients with RA, possession rates are high, with 23% or less of the devices in possession being abandoned. Overall, satisfaction rates were high. Factors associated with usage varied among categories and comprised, apart from the number of devices in possession and variables related to health status, also aspects of satisfaction with the device or related services or self-efficacy. The latter findings underline the need for a systematic evaluation of the outcomes of assistive devices by prescribing health professionals or suppliers in every individual case.

Abstract: OBJECTIVE: To investigate the responsiveness of the Michigan Hand Outcomes Questionnaire (MHQ) in patients with rheumatoid arthritis (RA) who were treated in a multidisciplinary hand clinic. DESIGN: Observational study comparing the responsiveness of the MHQ with that of various other outcome measures for hand function. SETTING: Multidisciplinary hand clinic within a tertiary referral center for rheumatologic care. PARTICIPANTS: Twenty-eight patients with problems in hand function due to RA were assessed before and 3 months after conservative and/or surgical treatment. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Assessments included, apart from a previously validated Dutch language version of the MHQ, a visual analog scale for pain, grip strength, the Sequential Occupational Dexterity Assessment, the Arthritis Impact Measurement Scales (AIMS) hand and finger function scale, and each patient's rating of subjective change in hand function. Measurements of responsiveness included the standardized response mean (SRM), effect size, and responsiveness ratio. In addition, the Spearman rank correlations (rho) between the change scores of the MHQ and those of other measures of hand function were calculated. RESULTS: The mean MHQ total score improved significantly between baseline (mean +/- standard deviation, 48.3+/-12.2) and follow-up (mean, 54.7+/-16.9) (change score, -7.2; 95% confidence interval, -11.1 to -3.3). The SRM, effect size, and responsiveness ratio of the MHQ total score were -0.72, -0.52, and -1.99, respectively. Significant associations were found between the changes of the MHQ total score and each patient's rating of subjective change in hand function (rho=.64, P=.001) and the change score of the AIMS hand function scale (rho=-.24, P=.260). CONCLUSIONS: The MHQ proved to be a responsive measure of hand function in patients with RA who were treated in connection with a multidisciplinary hand clinic.

Abstract: OBJECTIVE: To investigate the utility of serum COMP level measurements as a predictor of future damage of the weight-bearing (large) joints in RA patients participating in intensive exercise. METHODS: Data of the 281 completers of a 2-yr randomized controlled trial (Rheumatoid Arthritis Patients In Training; RAPIT) comparing the effects of usual care physical therapy with high-intensity weight-bearing exercises were analysed. The primary outcome variable was defined as the change in radiological joint damage (Larsen score) of the large joints. Potential predictors of outcome were defined: baseline and change in serum level of COMP after 3 months, baseline radiological damage of the large and small joints, number of months on glucocorticoids, change in disease activity and in physical capacity (aerobic fitness and muscle strength) after 2 yrs, and participation in the exercise group. RESULTS: In cross-sectional evaluation of baseline data, we found strong association between the high serum COMP level and current damage of the large joints. Serum COMP level at baseline, however, was not associated with an increased rate of radiological joint damage after 2 yrs of follow-up. Furthermore, neither interaction between baseline COMP level and participation in exercises, nor change in COMP level after 3 months of exercising were associated with future damage of the large joints. CONCLUSION: Neither baseline serum COMP level nor its individual change after 3 months from start of intensive exercise predict longitudinal progression of damage of the large joints in this population.
