Eficácia do treinamento de restrição do fluxo sanguíneo na osteartrose de joelho: revisão de literatura

Abstract

Introduction: Osteoarthritis is a chronic degenerative condition, of inflammatory origin, which causes progressive damage to the joint, causing pain, loss of mobility, quadriceps atrophy and, consequently, reduced functionality. In view of this, the Blood Flow Restriction Training (TRFS) technique has recently been developed, which promotes low-load exercises using a pressure sphygmomanometer cuff so that there is a partial restriction of blood flow in the area, creating an environment local anaerobic resulting in greater muscle activation. Objective: To verify the effectiveness of TRFS in improving muscle strength, pain and function in individuals with KOA. Methodology: This is a literature review, with searches in the PubMed and BVS databases, from October to September 2023, where only randomized clinical trials with patients with KOA were included. The keywords used were “knee osteoarthrosis”; “knee osteoarthritis”; “blood flow restriction”; “vascular occlusion”; “Kaatsu”; “physiotherapy” and “exercise”. Results: 47 articles were identified and, after applying the inclusion criteria, 8 were selected for the study. The results found were improvements in pain, muscle strength and, consequently, in the functionality of individuals. Conclusion: TRFS proved to be effective and beneficial for improving pain, muscle strength and functionality in patients with KOA, being superior to control groups and other techniques covered in the majority of studies.
