Autoantibodies to cyclic citrullinated peptides predict progression to rheumatoid arthritis in patients with undifferentiated arthritis: a prospective cohort study.

OBJECTIVE: Rheumatoid arthritis (RA) is a common, severe, chronic inflammatory joint disease. Since the disease may initially be indistinguishable from other forms of arthritis, early diagnosis can be difficult. Autoantibodies seen in RA can be detected years before clinical symptoms develop. In an inception cohort of patients with recent-onset arthritis, we undertook this study to assess the predictive value of RA-specific autoantibodies to cyclic citrullinated peptides (CCPs) in patients with undifferentiated arthritis (UA). METHODS: Anti-CCP2 antibody tests were performed at baseline in 936 consecutive, newly referred patients with recent-onset arthritis. Patients who could not be properly classified 2 weeks after inclusion were categorized as having UA. Patients with UA were followed up for 3 years and evaluated for progression of their disease to RA as defined by the American College of Rheumatology (ACR) 1987 revised criteria. RESULTS: Three hundred eighteen of 936 patients with recent-onset arthritis were classified as having UA and were available for analysis. After 3 years of followup, 127 of 318 UA patients (40%) had been classified as having RA. RA had developed in 63 of 249 patients (25%) with a negative anti-CCP test and in 64 of 69 patients (93%) with a positive anti-CCP test (odds ratio 37.8 [95% confidence interval 13.8-111.9]). Multivariate analysis of the presence of anti-CCP antibodies and parameters from the ACR criteria identified polyarthritis, symmetric arthritis, erosions on radiographs, and anti-CCP antibodies as significant predictors of RA. CONCLUSION: Testing for anti-CCP antibodies in UA allows accurate prediction of a substantial number of patients who will fulfill the ACR criteria for RA.

Evidence for additional genetic risk indicators of relapse-onset MS within the HLA region.

BACKGROUND: Human leukocyte antigen (HLA)-DR2 carriership is associated with an increased risk for MS. Genome searches using microsatellite markers have consistently shown that additional genetic factors contribute to susceptibility for MS. OBJECTIVE: To identify loci within the HLA region that predispose to relapse-onset MS independently of HLA-DR2. METHOD: A case-control study involving 159 patients with definite relapse-onset MS and 273 control subjects was conducted. Six highly polymorphic microsatellite markers encoded within the HLA-C to DR region, that is, D6S1014, D6S273, TNFa, MIB, C1_2_5, and C1_3_2, three single-nucleotide tumor necrosis factor (TNF) promoter gene polymorphisms at positions -238, -308, and -376, and HLA-DR2 carriership were typed. RESULTS: These data confirmed the well-known association between the HLA-DR2 haplotype and relapse-onset MS, yielding an odds ratio (OR) of 3.6 (95% CI: 2.4 to 5.4; p < 0.0001). Multivariate analyses revealed that C1_3_2*354 was also associated with an increased risk for developing relapse-onset MS independently of HLA-DR2 (OR: 2.0; 95% CI: 1.2 to 3.1; p = 0.004). This allele is encoded within an ancestral haplotype that is highly linked to HLA-DR3. The joint effect of this ancestral haplotype and HLA-DR2 resulted in an OR of 8.7 (95% CI: 2.7 to 29; p < 0.0001) to develop relapse-onset MS. In addition, a protective risk factor was found: carriers of TNFa*107 had a 0.5-fold lower risk to develop relapse-onset MS (95% CI: 0.3 to 0.9; p = 0.026). CONCLUSION: Within the HLA region, other loci besides HLA-DR2 haplotype modulate susceptibility for relapse-onset MS.

Polymorphisms in or near tumour necrosis factor (TNF)-gene do not determine levels of endotoxin-induced TNF production.

Innate differences in tumour necrosis factor (TNF) production have been associated with susceptibility for and outcome of inflammatory diseases. Several studies have tried to identify whether polymorphisms in or near the TNF gene or other markers on the short arm of chromosome 6 (6p21) are related to differences in TNF production. Data on these associations are conflicting. Therefore, we conducted a study among 129 healthy individuals in which TNF production was determined upon stimulation with endotoxin in whole blood cultures. TNFa microsatellite, TNF single nucleotide polymorphisms at position +489, -238, -308 and -376 typing was performed. The data revealed that alleles of TNFa microsatellite and carriership of TNF polymorphisms were not related to TNF production. We conclude that the genes determing the differences in endotoxin-induced TNF production have not been yet identified.

Secretion of anti-citrulline-containing peptide antibody by B lymphocytes in rheumatoid arthritis.

OBJECTIVE: To understand the regulation of anti-citrulline-containing peptide antibody (anti-CCP) production in rheumatoid arthritis (RA), production of anti-CCP by B cells derived from peripheral blood (PB), bone marrow (BM), and synovial fluid (SF) was examined. METHODS: Purified PB and SF B cells were isolated by negative selection and then cultured in the absence or presence of L-CD40 ligand cells and interleukin-10 or anti-CD3-activated T cells. Total IgM and IgM-anti-CCP were detected after 14 days of culture by enzyme-linked immunosorbent assay. Enzyme-linked immunospot assays were performed to analyze the frequency of cells that spontaneously produced IgM-anti-CCP in BM and SF B cells. RESULTS: IgM-anti-CCP autoantibodies were induced in PB B cells from healthy controls and RA patients following coculture with activated T cells or application of the CD40 activation system, whereas no production could be detected when PB B cells were cultured in the absence of a stimulus. SF and BM B cells from anti-CCP-seropositive RA patients, but not anti-CCP-seronegative patients, actively produced IgM-anti-CCP without stimulation. The frequency of spontaneous production of IgM-anti-CCP among the IgM-secreting cells ranged from 2.2% to 25%. CONCLUSION: These results indicate the presence of B cell precursors for anti-CCP autoantibodies that are able to produce antibodies upon stimulation in the PB B cell repertoire of healthy controls and patients with RA. In contrast, B cells that actively secreted anti-CCP were specifically present in the BM and SF compartment of anti-CCP-seropositive RA patients. The local presence of anti-CCP-secreting cells in the inflamed joints provides evidence for an antigen-driven maturation of CCP-specific B cells at the site of inflammation in RA.

Psychometric properties of the Impact on Participation and Autonomy Questionnaire.

OBJECTIVE: To examine the homogeneity, test-retest reliability, construct validity, and concurrent validity of the Impact on Participation and Autonomy Questionnaire (IPAQ). DESIGN: Cross-sectional study with a test-retest subsample. PATIENTS: One hundred twenty-six persons from 5 diagnostic groups recruited from the outpatients clinics of 2 rehabilitation centers and the rehabilitation department of an academic hospital. INTERVENTIONS: The IPAQ and 3 other self-administered questionnaires (Sickness Impact Profile [68-item version], London Handicap Scale [LHS], Medical Outcome Study Short-Form Health Survey). The IPAQ was completed twice by 75 respondents within approximately 2 weeks. RESULTS: The IPAQ addresses autonomy and participation in 5 domains: autonomy indoors, family role, autonomy outdoors, social relations, and work and educational opportunities. Cronbach's alpha for the several domains ranged between.81 and.91, indicating good homogeneity. On item level, weighted kappas ranged between.56 and.90. On domain level, the test-retest reliability of the IPAQ was good: intraclass correlation coefficients ranged between.83 and.91. Convergent validity was largely supported by the correlations between 4 domains of the LHS and the IPAQ. Discriminant validity was best demonstrated by low correlations between the IPAQ and 2 domains of the LHS representing theoretically different constructs. CONCLUSION: The IPAQ is a reliable and valid instrument for assessing autonomy and participation in chronic disorders. Its responsiveness requires further study.

Submaximal exercise capacity and maximal power output in polio subjects.

OBJECTIVES: To compare the submaximal exercise capacity of polio subjects with postpoliomyelitis syndrome (PPS) and without (non-PPS) with that of healthy control subjects, to investigate the relationship of this capacity with maximal short-term power and quadriceps strength, and to evaluate movement economy. DESIGN: Cross-sectional survey. SETTING: University hospital. PARTICIPANTS: Forty-three polio subjects (25 PPS, 18 non-PPS) and 12 control subjects. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Power output, oxygen uptake, and heart rate were measured in an incremental submaximal cycle ergometry test. Maximal short-term power was measured in 5-second all-out efforts. Knee extensor strength was measured on a chair dynamometer. RESULTS: The mean submaximal power +/- standard deviation at 80% of heart rate reserve of 83.8 +/- 29.9 watts in the polio subjects was significantly less than the mean submaximal power of 142.1 +/- 30.4 watts in the control group. However, expressed as a percentage of the maximal short-term power, submaximal power did not differ between the groups. Strength and maximal short-term power correlated significantly (p < .005) with submaximal power (r = .64 and .76, respectively). The oxygen uptake was higher than theoretically expected for the given submaximal power output in polio subjects, and appeared to increase with increasing asymmetry in strength and power between legs. No differences were found between PPS and non-PPS subjects. CONCLUSION: The submaximal work capacity of polio subjects was severely reduced, mainly in association with the reduced muscle capacity. And, because of a reduced movement economy, their energy cost was elevated. Although muscle loads in activities such as walking and climbing stairs differ from cycling, they also may require elevated relative levels of effort, predisposing subjects to premature fatigue in sustained activity.

The diagnostic properties of rheumatoid arthritis antibodies recognizing a cyclic citrullinated peptide.

OBJECTIVE: Since modern treatment of rheumatoid arthritis (RA) is shifting toward aggressive antirheumatic therapy in an early phase of the disease, diagnostic tests with high specificity are desirable. A new serologic test (anti-cyclic citrullinated peptide [anti-CCP] enzyme-linked immunosorbent assay [ELISA]) was developed to determine the presence of antibodies directed toward citrullinated peptides, using a synthetic peptide designed for this purpose. METHODS: A cyclic peptide variant that contains deiminated arginine (citrulline) was designed and used as antigenic substrate in ELISA. Test parameters and diagnostic characteristics of the test were studied in patients with and without RA, in patients with various infectious diseases, and in a group of patients from an early arthritis clinic (EAC). RESULTS: Using prevalent RA and non-RA sera, the anti-CCP ELISA proved to be extremely specific (98%), with a reasonable sensitivity (68%). Also, in the EAC study group, the anti-CCP ELISA appeared to be highly specific for RA (96%). In comparison with the IgM rheumatoid factor (IgM-RF) ELISA, the anti-CCP ELISA had a significantly higher specificity (96% for CCP versus 91% for IgM-RF; P = 0.016) at optimal cut-off values. The sensitivity of both tests for RA was moderate: 48% and 54% for the anti-CCP ELISA and the IgM-RF ELISA, respectively (P = 0.36). Combination of the anti-CCP and the IgM-RF ELISAs resulted in a significantly higher positive predictive value of 91% (P = 0.013) and a slightly lower negative predictive value of 78% (P = 0.35) as compared with the use of the IgM-RF ELISA alone. The ability of the 2 tests performed at the first visit to predict erosive disease at 2 years of followup in RA patients was comparable (positive predictive value 91%). CONCLUSION: The anti-CCP ELISA might be very useful for diagnostic and therapeutic strategies in RA of recent onset.

The prognostic value of anti-cyclic citrullinated peptide antibody in patients with recent-onset rheumatoid arthritis.

OBJECTIVE: To study the predictive value of anticyclic citrullinated peptide antibody (anti-CCP) in patients with recent-onset rheumatoid arthritis (RA). METHODS: Outcome in terms of physical disability (Health Assessment Questionnaire) and radiologic damage (modified Sharp method) over 3-year and 6-year periods was determined in an inception cohort of 273 RA patients who had had disease symptoms for <1 year at study entry. Anti-CCP titers were determined at baseline and considered positive as recently described. Their prognostic value was studied by means of multiple regression analysis, in which anti-CCP positivity, sex, age at study entry, IgM rheumatoid factor (IgM-RF) status, Disease Activity Score (DAS), HLA-DR4 status, and (in a separate group of patients) shared epitope status were used as independent variables, and radiologic damage and functional disability as dependent variables. RESULTS: Patients with anti-CCP had developed significantly more severe radiologic damage after 6 years of followup. In multiple regression analysis, radiologic damage after 6 years followup was significantly predicted by IgM-RF status, radiologic score at entry, and anti-CCP status. Functional disability was significantly predicted by sex, age at entry, IgM-RF status, and DAS. CONCLUSION: Our data show that in almost 70% of RA patients, anti-CCP antibody is present at the early stages of disease. Anti-CCP-positive patients developed significantly more severe radiologic damage than patients who were anti-CCP negative, although in multiple regression analysis the additional predictive value was rather moderate.

Detection of cerebral involvement in patients with active neuropsychiatric systemic lupus erythematosus by the use of volumetric magnetization transfer imaging.

OBJECTIVE: To determine whether volumetric magnetization transfer imaging (MTI) histogram analysis can detect abnormalities in patients with active neuropsychiatric systemic lupus erythematosus (NPSLE) and to compare the MTI findings in patients with active NPSLE, chronic NPSLE, and multiple sclerosis (MS), as well as in normal control subjects. METHODS: Eight female and 1 male patient with active nonthromboembolic NPSLE (mean +/- SD age 39 +/- 9 years), 10 female patients with chronic NPSLE (age 33 +/- 11 years), 10 female patients with SLE and no history of NPSLE (non-NPSLE; age 34 +/- 11 years), 10 female patients with inactive MS (age 41 +/- 6 years), and 10 healthy control subjects (age 33 +/- 11 years) underwent MTL. Using the MTI scans, histograms were composed from which we derived a variety of parameters that quantitatively reflect the uniformity of the brain parenchyma as well as the ratio of cerebrospinal fluid to intracranial volume, which reflects atrophy. RESULTS: The magnetization transfer ratio (MTR) histograms in the non-NPSLE group and the healthy control group were similar, whereas those in the chronic NPSLE and MS groups were flatter. There was also flattening of the histograms in the active NPSLE group, but with a shift toward higher MTRs. CONCLUSION: Our results indicate that volumetric MTI analysis detects cerebral changes in the active phase of NPSLE. The abnormalities in the brain parenchyma of patients with chronic NPSLE produced MTI values that were the same as those in patients with inactive MS. MTI values in the active phase of NPSLE differed from those in the chronic phase, which might reflect the presence of inflammation. These preliminary results suggest that MTI might provide evidence for the presence of active NPSLE. MTI might also prove to be a valuable technique for monitoring treatment trials.

Innate production of interleukin-10 and tumor necrosis factor affects the risk of multiple sclerosis.

Multiple sclerosis (MS) typically presents with a relapsing-remitting onset. This can be distinguished from primary progressive MS. Typical MS is characterized by a profound inflammatory reaction in which anti-inflammatory cytokine interleukin-10 (IL-10) and pro-inflammatory cytokine tumor necrosis factor (TNF) may play a pivotal role. We tested the hypothesis that patients with MS have a distinct innate cytokine production that contributes to the susceptibility for and outcome of MS. The innate cytokine production of patients was estimated as the average production of cytokines in lipopolysaccharide -stimulated whole-blood cultures of 2 to 5 first-degree healthy family members. A total of 126 family members of 50 patients with typical MS, 61 family members of 25 patients with primary progressive MS, and 129 control subjects of 54 families were enrolled in this study. We found that members of families with low IL-10 and high TNF production had a fourfold increased risk of developing typical MS compared with members of families with high IL-10 and low TNF production. Patients with MS were eightfold more likely to develop typical MS than primary progressive MS when they belonged to families with low IL-10 and high TNF production. The presence of human leukocyte antigen-DR2 was associated with MS but not with TNF production. This study shows that typical MS is associated with an innate pro-inflammatory cytokine profile in contrast to primary progressive MS.

The effects of knee-ankle-foot orthoses in the treatment of Duchenne muscular dystrophy: review of the literature.

OBJECTIVE: A systematic review of the available literature on the effectiveness of knee-ankle-foot orthoses in the treatment of Duchenne muscular dystrophy. DESIGN: A computer search was carried out (MEDLINE 1966-97, CINAHL 1982-97) using the key words muscular dystrophy, rehabilitation, locomotion, braces or orthotic devices. References in relevant publications and nonindexed journals were also examined. Criteria to include and exclude articles were formulated. We used a systematic review procedure to evaluate the literature. Seven methodological criteria were formulated. RESULTS: Thirty articles describing 35 studies met the inclusion criteria for our review, nine studies were selected based on completeness of information on study population, treatment and quantitative presentation of the effect outcome. Operations on the lower limbs were performed on most patients. A concomitant programme of rehabilitation was not described thoroughly. A percentage success of treatment was calculated for eight studies. Median percentage after one year was 75.1, after two years 47.9 and after three years 24.3. The median for the means of independent walking was 24 months, the median for the means of assisted walking was 36.2 months and the median for the means of standing ability was 50.5 months duration. CONCLUSION: The scientific strength of the studies reviewed is poor. It seems that the use of knee-ankle foot orthoses can prolong assisted walking and standing, but it is uncertain whether it can prolong functional walking. The boys that benefit most have a relatively low rate of deterioration, are capable of enduring an operation and are well motivated.

Disability and functional assessment in former polio patients with and without postpolio syndrome.

OBJECTIVES: To compare perceived health problems and disability in former polio subjects with postpolio syndrome (PPS) and those without postpolio syndrome (non-PPS), and to evaluate perceived health problems, disability, physical performance, and muscle strength. DESIGN: Cross-sectional survey; partially blinded data collection. SUBJECTS: One hundred three former polio subjects, aged 32 to 60yrs. This volunteer sample came from referrals and patient contacts. Criterion for PPS: new muscle weakness among symptoms. MAIN OUTCOME MEASURES: Nottingham Health Profile (NHP), adapted D-code of the International Classification of Impairments, Disabilities and Handicaps, performance test, and muscle strength assessment. RESULTS: PPS subjects (n = 76) showed higher scores (p < .001) than non-PPS subjects (n = 27) within the NHP categories of physical mobility, energy, and pain. On a 16-item Polio Problems List, 78% of PPS subjects selected fatigue as their major problem, followed by walking outdoors (46%) and climbing stairs (41%). The disabilities of PPS subjects were mainly seen in physical and social functioning. No differences in manually tested strength were found between patient groups. PPS subjects needed significantly more time for the performance test than non-PPS subjects and their perceived exertion was higher. Perceived health problems (NHP-PhysMobility) correlated significantly with physical disability (r = .66), performance-time (r = .54), and muscle strength (r = .38). With linear regression analysis, 54% of the NHP-PhysMobility score could be explained by the performance test (time and exertion), presence of PPS, and muscle strength, whereas strength itself explained only 14% of the NHP-PhysMobility score. CONCLUSIONS: PPS subjects are more prone to fatigue and have more physical mobility problems than non-PPS subjects. In former polio patients, measurements of perceived health problems and performance tests are the most appropriate instruments for functional evaluation.

Handicap questionnaires: what do they assess?

BACKGROUND AND PURPOSE: There is an increasing need to get insight into the social and societal impact of chronic conditions on a person's life, i.e. person-perceived handicap. The purpose of this study is to report how current handicap questionnaires assess handicap. METHOD: A literature search using both Medline and the database of the Dutch Institute of Allied Health Professions (NPi) was conducted for handicap questionnaires. Questionnaires were included if addressing handicaps or life roles, environmental influences and social consequences of a disease. Excluded were questionnaires focusing on only impairments, disabilities or quality of life. RESULTS AND CONCLUSION: 20 questionnaires were identified. Handicap is not uniformly defined in these questionnaires. Based on different concepts, the various questionnaires encompass different domains and different aspects are emphasized in similar domains. Fourteen questionnaires assess society-perceived handicaps, and do not address the life roles, care needs or individual problem-experience. Six questionnaires are to some extent person-perceived, but a generic person-perceived handicap questionnaire could not be identified. It is concluded that development of a generic person-perceived handicap questionnaire is essential for adequate assessment of needs, outcome, and relevance of rehabilitation interventions from the individual's point of view.

The development of a handicap assessment questionnaire: the Impact on Participation and Autonomy (IPA).

OBJECTIVE: To report on the feasibility and psychometric properties in terms of homogeneity and construct validity of a newly developed handicap questionnaire focusing on person-perceived handicaps: the Impact on Participation and Autonomy (IPA). DESIGN: Cross-sectional. SETTING, subjects and outcome measure: One hundred consecutive individuals from the outpatient clinic of the department of rehabilitation of an academic hospital administered the new questionnaire IPA. RESULTS: The results show good homogeneity and construct validity of the IPA. Factor analysis showed that the scale consists of four factors, explaining 68% of the total variance: social relationships, autonomy in self-care, mobility and leisure, and family role. Homogeneity of the four subscales was considered good, Cronbach's alpha ranged from 0.84 (family role) to 0.87 (social relationships). Feasibility in terms of the number of missing values and administration time needed was satisfactory. CONCLUSION: The first results suggest that the IPA promises to be a useful handicap questionnaire. Further research is needed to establish test-retest reliability, convergent validity and responsiveness to change.

Effectiveness of corticosteroid injections versus physiotherapy for treatment of painful stiff shoulder in primary care: randomised trial.

OBJECTIVE: To compare the effectiveness of corticosteroid injections with physiotherapy for the treatment of painful stiff shoulder. DESIGN: Randomised trial. SETTING: 40 general practices. SUBJECTS: 109 patients consulting general practitioners for shoulder pain were enrolled in the trial. INTERVENTIONS: Patients were randomly allocated to 6 weeks of treatment either with corticosteroid injections (53) or physiotherapy (56). MAIN OUTCOME MEASURES: Outcome assessments were carried out 3, 7, 13, 26, and 52 weeks after randomisation; some of the assessments were done by an observer blind to treatment allocation. Primary outcome measures were the success of treatment as measured by scores on scales measuring improvement in the main complaint and pain, and improvement in scores on a scale measuring shoulder disability. RESULTS: At 7 weeks 40 (77%) out of 52 patients treated with injections were considered to be treatment successes compared with 26 (46%) out of 56 treated with physiotherapy (difference between groups 31%, 95% confidence interval 14% to 48%). The difference in improvement favoured those treated with corticosteroids in nearly all outcome measures; these differences were statistically significant. At 26 and 52 weeks differences between the groups were comparatively small. Adverse reactions were generally mild. However, among women receiving treatment with corticosteroids adverse reactions were more troublesome: facial flushing was reported by 9 women and irregular menstrual bleeding by 6, 2 of whom were postmenopausal. CONCLUSIONS: The beneficial effects of corticosteroid injections administered by general practitioners for treatment of painful stiff shoulder are superior to those of physiotherapy. The differences between the intervention groups were mainly the result of the comparatively faster relief of symptoms that occurred in patients treated with injections. Adverse reactions were generally mild but doctors should be aware of the potential side effects of injections of triamcinolone, particularly in women.

Citrulline is an essential constituent of antigenic determinants recognized by rheumatoid arthritis-specific autoantibodies.

Only a few autoantibodies that are more or less specific for RA have been described so far. The rheumatoid factor most often tested for is not very specific for RA, while the more specific antiperinuclear factor for several reasons is not routinely used as a serological parameter. Here we show that autoantibodies reactive with synthetic peptides containing the unusual amino acid citrulline, a posttranslationally modified arginine residue, are specifically present in the sera of RA patients. Using several citrulline-containing peptide variants in ELISA, antibodies could be detected in 76% of RA sera with a specificity of 96%. Sera showed a remarkable variety in the reactivity pattern towards different citrulline-containing peptides. Affinity-purified antibodies were shown to be positive in the immunofluorescence-based antiperinuclear factor test, and in the so-called antikeratin antibody test, and were reactive towards filaggrin extracted from human epidermis. The specific nature of these antibodies and the presence of these antibodies early in disease, even before other disease manifestations occur, are indicative for a possible role of citrulline-containing epitopes in the pathogenesis of RA.

Intra-articular triamcinolone acetonide injection in patients with capsulitis of the shoulder: a comparative study of two dose regimens.

BACKGROUND AND PURPOSE: Although corticosteroid injections have been reported to be effective in capsulitis of the shoulder, the optimal dose has not been established. The purpose of this study was to compare relief of symptoms following a lower dose with that following a higher dose of triamcinolone acetonide given intra-articularly. SUBJECTS: Thirty-two patients were given low dose suspension; 25 patients were given high dose suspension. METHOD: Randomized, double-blind clinical trial. Each patient was given a course of three injections. Pain, sleep disturbance, functional impairment and passive range of motion (ROM) were assessed at intake and at one, three and six weeks after the initial injection. Data were analysed by independent sample t-tests and nonparametric Mann-Whitney U-tests. RESULTS: The group which received the 40 mg dose showed significantly greater improvement than the group receiving the 10 mg dose. CONCLUSIONS: The study shows that in the treatment of frozen shoulder greater symptom relief is obtained with a dose of 40 mg triamcinolone acetonide intra-articularly than with a dose of 10 mg. The effect on pain and sleep disturbance was more marked than on ROM. Intra-articular injections with triamcinolone acetonide appear to be an effective method to obtain symptom relief for patients with painful capsulitis of the shoulder.
