Effects of home-based exercise program on the functional status and the quality of life in patients with rheumatoid arthritis: 1-year follow-up study.

We previously reported the efficacy of a 4-week home-based exercise therapy for patients with rheumatoid arthritis (RA). In this study, we aimed to investigate whether short-term improvements in the functional status and quality of life were maintained at 1 year. Patients who completed 4-week home-based exercise program were advised to maintain the same exercises for 1 year duration. Changes of functional status and quality of life in patients with RA were evaluated by the Health Assessment Questionnaire (HAQ) and the Rheumatoid Arthritis Quality of Life Scale (RAQoL). The change of the variables at the different time points (baseline, 4 weeks, and 1 year) was assessed by the repeated measure of ANOVA test with Geisser-Greenhouse correction. Pairwise ANOVA comparisons adjusted using the Bonferroni correction were conducted. Twenty-eight (63.6%) of 44 patients were available for follow-up at 1 year. The results of repeated measure ANOVA showed that there was a statistically significant difference between three assessments in the HAQ (P = 0.015) and RAQoL (P = 0.037) scores at the end of the follow-up. Improvements in the functional status and health-related quality of life at 4 weeks were maintained at 1-year follow-up. In conclusion, we observed significant improvements in the functional status and health-related quality of life by 4-week home-based exercise program. Furthermore, these improvements were maintained at 1-year follow-up. Further studies are needed to confirm the usefulness of the home-based exercise therapy.

The validity and reliability of the Turkish version of the Rheumatoid and Arthritis Outcome Score (RAOS) in patients with rheumatoid arthritis.

The goal of our study was to develop a Turkish version of the Rheumatoid and Arthritis Outcome Score (RAOS) in patients with rheumatoid arthritis (RA) and to assess its reliability, validity, and sensitivity to change. The Turkish version of RAOS was developed according to cross-cultural guidelines by using the "translation-back translation" method. Fifty-eight patients with RA were assessed with it. To assess its validity, patients were also evaluated with Turkish versions of the Health Assessment Questionnaire, five subscales of Arthritis Impact Measurement Scales, and the Rheumatoid Arthritis Quality of Life questionnaire. Test-retest reliability of the RAOS questionnaire was calculated on 58 patients within 1 week. Construct validity was investigated with use of Spearman's rank correlation coefficient. Test-retest reliability was assessed with use of the intraclass correlation coefficient (ICC) and Cronbach's alpha score. Sensitivity to change after the 4-week home-based exercise program was evaluated with paired t test comparisons. The Turkish version of the RAOS met set criteria of reliability and validity. The random ICC for the five subscales ranged from 0.76 to 0.94. Interitem correlation measured by Cronbach's alpha ranged from 0.81 to 0.94. Correlations were found between RAOS subscales and all of the evaluation parameters (p < 0.01). RAOS subscales showed significant improvements after the 4-week home exercise program except for the symptom and quality of life subscales (p < 0.05). The effect sizes were ranged from 0.20 to 0.37 and were considered small. The results of this study showed that the Turkish version of RAOS was reliable, valid, and responsive in patients with rheumatoid arthritis.

Comorbidity in patients after stroke: impact on functional outcome.

OBJECTIVE: To evaluate the incidence of comorbid diseases and their impact on functional outcome in patients after stroke. DESIGN: A prospective study. SUBJECTS: A total of 140 patients after stroke. METHODS: Comorbidities were assessed with the Liu comorbidity index. Functional independence was evaluated using the Functional Independence Measure (FIM). The relationship between comorbidities and functional outcomes were investigated. The impact of comorbidities on functional outcome was examined with multiple stepwise regression analysis. RESULTS: Ninety-four (67%) of 140 patients completed the study. The most frequent comorbid condition was hypertension at the initial visit. The weighted comorbidity index at baseline was negatively correlated with the follow-up FIM score and functional gain. Multiple regression analysis revealed that follow-up FIM score could be best explained by FIM at admission and the contribution of the weighted comorbidity index to functional outcome was 3.1%. CONCLUSION: Comorbid diseases are common among patients after stroke. They were shown to have a negative correlation with functional outcome; however, their impact on functional outcome was not clear. The proper evaluation of comorbid conditions should be included in stroke outcome research.
