RESUMEN
BACKGROUND: Reduction in flexibility and mobility are important factors that lead to impairments in quality of life, reduction of exercise tolerance, and a decreased pulmonary capacity with the progression of Ankylosing Spondylitis (AS). AIM: The purpose of this study was to investigate the effects of Pilates exercises on mobility, quality of life, and respiratory muscle strength in patients with AS. METHODS: Forty patients with AS were randomly divided into two groups as Pilates group and the control group. The Pilates group performed Pilates exercises in supervised group sessions and the control group performed conventional exercises at home three days a week for eight weeks. The main outcome measure was respiratory muscle strength. Secondary outcome measures were forced vital capacity (FVC), forced expiratory volume in one second (FEV1) FEV1/FVC ratio, chest expansion, Bath indices (BASDAI, BASMI), Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) and six-minute walk test (6MWT). All participants were assessed by a blind assessor at baseline and the end of eight weeks. RESULTS: Thirty-six AS patients (n = 19 in the Pilates group, n = 17 in the control group) completed the study. Respiratory muscle strength, FEV1/FVC, chest expansion, BASDAI, BASMI, ASQoL, and 6MWT significantly improved at the 8th week (p < .05) in the Pilates group, while inspiratory muscle strength, FEV1/FVC, chest expansion, and 6MWT showed significant improvements in the control group at 8th week compared to baseline (p < .05). No significant between-group differences were observed when the change over time values were compared (Δ). CONCLUSION: Both Pilates and home exercises seem to be effective for improving respiratory parameters and functional status in patients with AS. Pilates exercises without using any equipment and additional exercises is found to be useful for improving respiratory functions and disease-related symptoms.
RESUMEN
BACKGROUND: The Patient-Rated Wrist Evaluation (PRWE) is a patient-reported questionnaire focusing on symptoms and function in wrist pathologies. It consists of 15 questions regarding pain and functional activities of the wrist. Rheumatoid arthritis (RA) is a multi-systemic disease characterized by inflammation of the wrist and hand joints in almost all patients. This study aims to test the validity of PRWE in patients with RA. METHOD: Seventy-five patients with RA from a single outpatient clinic participated in the study. Patients filled out the Michigan Hand Outcomes Questionnaire (MHOQ) and grip strength of both hands were measured. Patients filled out the PRWE questionnaire consecutively once for the dominant and once for the non-dominant hand. Correlations between PRWE and MHOQ and grip strength scores were analyzed by Spearman's correlation method. RESULTS: Our results demonstrated that there was a very strong correlation between the PRWE and the MHOQ and a moderate correlation between the PRWE and grip strength (P < .001). PRWE also showed negative and fair correlation with grip strength of both hands (P < .001). CONCLUSIONS: The Patient-Rated Wrist Evaluation is a valid tool for evaluating wrist involvement in patients with RA. PRWE may be preferred in the busy clinical setting since it has simple and short questions. Additionally, it may provide a sensitive follow-up tool for patients separately using its subscales of pain and function.
