Background: In recent years, there has been a growing use of technological advancements to enhance the rehabilitation of individuals who have suffered from cerebrovascular accidents. Virtual reality rehabilitation programs enable patients to engage in a customized therapy program while interacting with a computer-generated environment. Therefore, our goal was to investigate the effectiveness of virtual reality in occupational therapy for people's rehabilitation after a cerebrovascular accident. Methods: We systematically searched databases (Pubmed/Medline, Scopus, Web of Science, and Science Direct) for randomized controlled trials published within the last 10 years. Studies involving adult stroke survivors undergoing virtual reality-based interventions aimed at improving upper-extremity motor function were included. The quality assessment followed PRISMA guidelines, with the risk of bias assessed using the Cochrane tool (version 6.4) and methodological quality evaluated using GRADEpro. Results: We selected sixteen studies that met the main criteria for the implementation of virtual reality technology. The interventions described in the articles focused mainly on the upper extremities and their fine motor skills. Conclusions: When used in conventional treatments to improve people's motor and cognitive functions after a cerebrovascular accident, virtual reality emerges as a beneficial tool. Additionally, virtual reality encourages adherence to the interventional process of rehabilitation through occupational therapy.

This systematic review aimed to assess the available body of published peer-reviewed articles related to the effects of Olympic combat sports (OCS) on cardiorespiratory fitness (CRF) in the non-athlete population. The methodological quality and certainty of evidence were evaluated using PRISMA, TESTEX, RoB, and GRADE scales. The protocol was registered in PROSPERO (code: CRD42023391433). From 4133 records, six randomized controlled trials were included, involving 855 non-athletes (mean age = 27.2 years old). The TESTEX scale reported all studies with a ≥ 60% (moderate-high quality) score. The GRADE scale indicated moderate to low certainty of evidence. It was only possible to perform a meta-analysis on direct methods to maximum oxygen consumption (VO 2 max). The main results indicated significant differences in favor of OCS compared to active/passive controls in VO 2 max (SMD = 4.61; 95%CI = 1.46 to 7.76; I 2 = 99%; p = 0.004), while the individual results of the studies reported significant improvements in favor of the OCS on the indirect methods of the CRF. OCS improved CRF in a healthy non-athlete population of different ages, specifically showing a significant improvement in VO 2 max with direct tests, such as cardiopulmonary tests. However, moderate to low certainty of evidence is reported, so no definitive recommendations can be established.
