Introduction: Balance and walking problems are common after a stroke and are associated with poor mobility, difficulties in carrying out daily activities, and an increased risk of falls. In recent years, virtual reality has increasingly been used in physiotherapy following a stroke, a relatively new approach that enhances motivation, adheres to the principles of motor learning theory, and allows the participant to constantly monitor the performance of its movements through the screen. Purpose: The purpose of the diploma work was to review randomized controlled trials in order to establish effects of exercise with virtual reality, added to physiotherapy in patients after a stroke to improve balance and walking. Methods: Randomized controlled trials were searched in databases: PubMed (MEDLINE), CINAHL and PEDro. Results: We included 13 randomized controlled trials published between 2008 and 2017 in the review. Discussion and conclusion: After examining the research, we cannot draw a conclusion that use of added virtual reality in patients after stroke for improving walking and balance is more effective than conventional physiotherapy itself. Additional research is needed in this area, with a larger number of subjects and more uniform assessment tool.
