Validation of the HAQ-UP-A (Health Assessment Questionnaire-Upper Limbs-Argentine Version) in Patients With Rheumatoid Arthritis.

Unlabelled: HAQ is considered the gold standard for the evaluation of functional capacity in patients with rheumatoid arthritis (RA), even though it does not focus on any particular anatomical region. With the objective of assessing functional disability of the hand in elderly patients with osteoarthritis, Baron et al. used a modified version of the HAQ which was calculated as the mean value for the categories mostly involving the upper extremities and named it 'HAQ-UP'.
