Abstract: Background and Objectives:The aim of this study was to investigate the clinical relevance of Michigan Hand Outcomes Questionnaire (MHQ) in patients with rheumatoid arthritis (RA) and to evaluate the relationship between MHQ and disease activity, quality of life (QL), and handgrip strength separately. Material and Method:Eighty RA were included in the study. Disease activity is evaluated with Disease Activity Score 28 (DAS28), pain is evaluated with Visual Analog Scale (VAS). The Disabilities of Arm, Shoulder and Hand (DASH), MHQ, Short-Form 36 (SF-36), and Health Assessment Questionnaire (HAQ), Arthritis Impact Measurement Scales-hand and finger function scale-2 (AIMS-2) were completed by all patients. Hand muscle strength (HMS) was measured with a hand-held dynamometer. Results:The MHQ moderately correlated with DAS28. When the patients were grouped according to three disease activity measurements, DASH scores were significantly higher with higher disease activity and MHQ scores were significantly lower with higher disease activity. A high correlation was found between MHQ total and HAQ, AIMS-2. The SF-36 scores were correlated with MHQ scores. Conclusions:The MHQ scores correlate with disease activity indices, functional disability, QL and DASH. The clinical relevance of MHQ, like DASH, is high and both questionnaires can be used effectively.
