Timed Up and Go (TUG) may prove to be a valid measure of functional status and an indicator of the efficacy of treatments comprising
rehabilitation interventions patients with rheumatoid arthritis and osteoarthritis.
According to a study published in 'International Journal of Rheumatic Diseases', the Health Assessment Questionnaire Disability Index (HAQ‐DI) has a strong connection with the Timed Up and Go (TUG) parameter in both rheumatoid arthritis (RA) and osteoarthritis (OA).
HAQ‐DI is a widely used Patient‐reported outcome measure for subjectively investigating the disability in arthritis patients; but, its ability to objectively measure physical function has not been exhibited. Jessica Douglas-Withers and researchers examined whether HAQ‐DI reflects objective measures of physical function in patients with OA and RA. Out of the total 139 patients, 71 patients with RA justified the American College of Rheumatology (ACR) criteria (1987) and 68 patients with OA explaining the ACR criteria for OA of the hip or knee, fulfilled the HAQ‐DI. The physical function was examined by using Timed Up and Go (TUG), 30 seconds Sit to Stand (STS), grip strength dynamometry and pedometer steps for 7 days. This study found a varied association between the HAQ‐DI and range of objective physical performance measures (STS, TUG, daily steps and grip strength) frequently used to examine the patients with chronic arthritis. The most active association with HAQ‐DI was with the TUG. There was a strong association between HAQ‐DI and grip strength in the OA group; on the other hand, the RA group revealed a moderate association.
As per the study authors, "To get a full and accurate
clinical picture, the health professionals should execute both subjective
patient‐reported outcome measures and objective physical performance measures
of disability."
