Effect of compression by elastic bandages on pain and function in individuals with knee osteoarthritis: protocol of a randomised controlled clinical trial
IntroductionAlthough compression is used to control pain in knee osteoarthritis (KOA), its clinical application is poorly supported, and there is a lack of scientific evidence to support its clinical use. As a low-cost and accessible protocol, compression using elastic bands could be a non-pharmacological intervention to reduce pain and improve physical function in individuals with KOA. This study aims to evaluate the effects of compression on pain and function in individuals with KOA.Methods and analysisA randomised controlled clinical trial will be conducted. Individuals with KOA (n=90; both sexes; between 40 and 75 years old) will be allocated to three groups (n=30/group): compression (compression by the elastic bandage on the affected knee, once a day for 20 min, on four consecutive days); sham (same protocol, but the elastic band is placed around the affected knee without compression) and control (no intervention). The individuals in the three groups will be evaluated 1 day before the first intervention, 1 day after the last intervention, and at the 12th and 24th weeks after the end of the intervention. Pain intensity by the Visual Analogue Scale and pain scale from Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) will be the primary outcomes. The secondary variables will be physical function assessed by the WOMAC questionnaire and physical tests (step test; 30 s sit and stand test; 40 m accelerated walk test). The Global Rating of Change Scale (GRC) will also be applied to quantify the volunteers’ perceived change.Ethics and disseminationThe project was approved by the Human Research Ethics Committee of the Federal University of São Carlos, São Paulo, Brazil (3955692). The results will be published in peer-reviewed journals.Trial registration numberNCT04724902.
