Association between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with knee osteoarthritis

Abstract

Abstract Objective To analyze the association between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with knee osteoarthritis (KOA). Methods A cross-sectional study was conducted involving 57 individuals with KOA. Evaluations were performed using the Exercise Adherence Rating Scale (EARS), the numerical rating scale (NRPS), the International Knee Documentation Committee (IKDC), The Central Sensitization Inventory (CSI), and the 30 sec sit and stand test (30SSST). Histograms were created to determine the normality of the data. The Kolmogorov-Smirnov test was used to determine the normality of the data. Thus, Pearson’s (r) and determination (R2) correlation coefficients were calculated to determine the strength of associations between variables. Results No significant association was found between adherence behavior or reasons for adherence and central sensitization symptoms, the intensity of pain on rest and movement, knee disability symptoms, and functionality. Conclusion No significant association was identified between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with KOA.
