OBJECTIVE: Virtual reality (VR) and computer-assisted cognitive rehabilitation (CACR) are two emerging rehabilitation therapies for stroke patients. The aim of this study was to compare the rehabilitation efficacy of these two treatments for patients with post-stroke cognitive impairment (PSCI).

METHODS: A network search of Embase, Web of Science, PubMed, Cochrane Library, VIP, WanFang Data, and CNKI databases was performed from their inception to February 2022 for screening randomized controlled trials related to VR and CACR in the treatment of PSCI. The quality of the included studies was assessed using the Cochrane risk bias assessment tool. The primary outcomes of the included studies contained at least one of the following clinical outcome measures: Mini-mental state examination (MMSE) or Montreal Cognitive Assessment (MoCA). After screening the literature, assessing the quality and extracting the data, a network meta-analysis was performed with STATA software.

RESULTS: A total of 21 randomized controlled trials were included, including 1,047 patients. The results of network meta-analysis showed that under MMSE index, VR group (p = 0.067) and CACR group (p = 0.054) tended to be superior to CT group, but it was not significant. Both the VR (p = 0.024) and CACR (p < 0.001) groups had significantly better outcomes compared to the conventional therapy group in terms of MoCA. The ranking results under both indicators showed that CACR had the best treatment effect, followed by VR.

CONCLUSION: In general, VR and CACR have superior efficacy compared with conventional therapy, in which CACR may be the best treatment option.
