Robot-Assisted Rehabilitation as a Form of Progressive Therapy in Upper Extremity Motor Recovery After Stroke: A Systematic Review

Background: Statistics show that the number of patients suffering from stroke and living with disability as a result has increased significantly worldwide between 1990 and 2021. This implies the necessity of continuous improvement of both treatment methods and rehabilitation, which is essential in the treatment process. According to the International Classification of Functioning (ICF), as many as 88% of patients do not regain functionality in their affected upper limbs six months after a vascular incident, which negatively affects their quality of life. Upper limb rehabilitation using robots is a progressive approach to restoring not only lost limb function, but above all, independence in activities of daily living. Aim of the study: The aim of this review is to determine the actual effects of rehabilitation using various robots in patients after cerebrovascular accidents and to compare these effects with those achieved by patients who participated in a non-robotic rehabilitation program. Methods: Studies published between 2019 and 2025 were included in the analysis. The analysis was written according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Results: Studies have shown improvement in upper limb function in patients exercising both with and without the use of a robot, but statistical data clearly show better results in patients undergoing therapy with robots. Conclusions: Studies have shown that the use of a rehabilitation program involving robots brings measurable improvements in many different aspects of upper limb function, and evidence confirming the effectiveness of this therapy encourages further research, refinement, and dissemination of this method and technology.
