Adherence Rating Scale (ARS) found Useful to Estimate Adherence to Exercise Therapy for patients with Knee Osteoarthritis

According to a recent study published in the journal BMC Musculoskeletal Disorders, the Adherence Rating Scale (ARS) holds good internal and external validity and can be used to determine the adherence to exercise therapy in patients with Knee osteoarthritis (KOA).

KOA is one of the most common chronic diseases and is the primary reason for the loss of motor function and disability in the elderly population. Exercise is considered one of the primary treatments for KOA management and is "strongly recommended" or "recommended" in the diagnosis and treatment guidelines of OA in many countries. Most scholars suggest it as the preferred rehabilitation technique for KOA patients. But, poor long-term adherence is a serious issue hindering the therapeutic outcomes of this treatment. This study was performed with an objective to fabricate a concise and practical adherence rating scale (ARS) based on the exercise therapy adherence prediction model in KOA patients.

To solve the basis of this study, a binary logistic regression model was created, with the adherence of 218 cases of KOA patients as the dependent variable by Wang J et al. and his researchers. The independent variables comprised of the patients' general information, exercise habits, knowledge, attitude, and exercise therapy. The ARS was made as per the regression coefficients designated to different variables in the model. The receiver operating characteristic curves and curve fitting helped to evaluate the effect of the ARS in estimating the adherence and to rule out the goodness of fit for the adhesion. A randomized controlled trial was used to determine the external validity of the ARS.

The following variables were applied to construct the adherence model and the ARS:

•    Age (1 point)

•    Education level (1 point)

•    The degree of social support (2 points)

•    Exercise habits (3 points)

•    Knowledge of KOA prevention and treatment (2 points),

•    The degree of care needed to treat the disease (1 point),

•    Familiarity with exercise therapy (4 points)

•    Treatment confidence (3 points)

The critical value of the total score of the ARS was 6.50, with a sensitivity and specificity of 87.20% and 76.34%. Hence, a KOA exercise therapy adherence model and a simple and practical ARS were fabricated.
