Introduction: Gait training is an important part of physical therapy treatment because a lot of post-stroke patients face difficulty walking. Virtual reality gait training is a relatively new form of gait training that is becoming increasingly more popular among physical therapists and patients. It is mostly done on a treadmill, with the use of different levels of virtual reality immersion. The effectiveness of virtual reality gait training in post-stroke patients is yet to be well researched. Purpose: To review research findings on the effectiveness of virtual reality gait training in stroke patients. Methods: Literature search was done in the PubMed database, searching for titles or abstracts that included the following words or phrases: (stroke OR poststroke) AND (virtual reality OR VR OR augmented reality OR AR) AND (gait OR walk OR walking). The review includes studies published until and including November 2022, when the search was conducted. On top of the search combination, three systhematic review aricles' reference lists were reviewed as well. Results: This literature review includes 12 studies, with a total of 311 participants, mostly being chronic ischemic stroke patients. Virtual reality gait trainig was carried out as a stand-alone or complimentary form of gait training. Non-immersive method was used six times, semi-immersion method twice, and immersive method four times. In our review, virtual reality gait training proved effective in improving gait speed (seven of eight studies), stride length (four of five studies), cadence three of five studies), improving scores of timed up and go test (six of seven studies) and ABC scale (two of three studies). Experimental groups were less often statistically better than control groups with other gait variables and used measurement instruments. Discussion and conclusion: We cannot claim that virtual reality gait training is a better form of gait training for improving all aspects of gait, however, it seems to be more effective in improving gait speed, stride length, cadence, outcome scores of timed up and go test and ABC scale. Furthermore, superiority of any level of immersion and long-term affectiveness also remain unclear.
