“…The immersion is a fundamental aspect of virtual reality and is correlated with the technology used by the system [ 20 , 21 ]. Features that characterize an immersive scenario involve the “graphics frame rate”, the “overall extent of tracking” (what body movements are detected), “tracking latency” (latency between head adjustment and relative modification in the simulation), the “quality of the images”, the “field of view” (dimension of the visual field of view versus normal vision and the extent of the displays encircling the user), the “visual quality of the rendered scene”, the “dynamics” and the “range of sensory modalities accommodated” [ 22 ].…”

In recent years, next to conventional rehabilitation’s techniques, new technologies have been applied in stroke rehabilitation. In this context, fully immersive virtual reality (FIVR) has showed interesting results thanks to the level of immersion of the subject in the illusional world, with the feeling of being a real part of the virtual environment. This study aims to investigate the efficacy of FIVR in stroke rehabilitation. PubMed, Web of Science and Scopus were screened up to November 2022 to identify eligible randomized controlled trials (RCTs). Out of 4623, we included 12 RCTs involving post-acute and chronic stroke survivors, with a total of 350 patients (234 men and 115 women; mean age 58.36 years). High heterogeneity of the outcomes considered, the results showed that FIVR provides additional benefits, in comparison with standard rehabilitation. In particular, results showed an improvement in upper limb dexterity, gait performance and dynamic balance, influencing patient independence. Therefore, FIVR represents an adaptable, multi-faceted rehabilitation tool that can be considered in post-stroke rehabilitation, improving the compliance of the patients to the treatment and increasing the level of functioning and quality of life of stroke survivors.

To investigate the efficacy of utilizing mixed reality technology-assisted teaching of a spinal medial branch nerve block. Twenty undergraduate students from a 5-year clinical medicine program in Fujian Medical University were selected. They were divided into group A and group B using a random number generator, with 10 students in each group. Group A used the traditional teaching method and Group B used the mixed reality technologyassisted teaching method. At the end of the teaching period, both groups were assessed on the blocking operation, number of punctures required, puncture time, and final error value (distance between the final position and the reference position). A questionnaire was administered to both groups to assess teaching satisfaction. The number of punctures required was 7.40 ± 1.26 and 2.10 ± 0.74 for groups A and B, respectively. The puncture time in group A was 297.80 ± 50.95 s and 65.60 ± 22.02 s in group B. All differences were significant p < 0.01. The final error of the puncture in group A was 2.24 ± 0.35 mm and 1.96 ± 0.26 mm in group B-not significant. Group B had (p < 0.01) higher evaluation scores than group A for teaching effectiveness, learning interest, initiative, and teaching satisfaction. The application of mixed reality technology in the teaching of posterior medial branch blocks of the spinal nerve is superior to previous methods. This method should be adopted wherever possible to enhance learning of this difficult technique.

“…HoloLens (Microsoft Corp) is a popular commercialized OST HMD that enables physicians to obtain immediate insight into patient information by overlaying it with the view of the clinical scenario. It helps medical students gain a better understanding of complex human anatomies or a better experience with treatment procedures and assists patients during rehabilitation and treatment [56]. In this review context, effective and successful applications of HoloLens as an image display component of an AR-assisted implant navigation system have been introduced in 2 studies [22,45].…”

Background The novel concept of immersive 3D augmented reality (AR) surgical navigation has recently been introduced in the medical field. This method allows surgeons to directly focus on the surgical objective without having to look at a separate monitor. In the dental field, the recently developed AR-assisted dental implant navigation system (AR navigation), which uses innovative image technology to directly visualize and track a presurgical plan over an actual surgical site, has attracted great interest. Objective This study is the first systematic review and meta-analysis study that aimed to assess the accuracy of dental implants placed by AR navigation and compare it with that of the widely used implant placement methods, including the freehand method (FH), template-based static guidance (TG), and conventional navigation (CN). Methods Individual search strategies were used in PubMed (MEDLINE), Scopus, ScienceDirect, Cochrane Library, and Google Scholar to search for articles published until March 21, 2022. This study was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and registered in the International Prospective Register of Systematic Reviews (PROSPERO) database. Peer-reviewed journal articles evaluating the positional deviations of dental implants placed using AR-assisted implant navigation systems were included. Cohen d statistical power analysis was used to investigate the effect size estimate and CIs of standardized mean differences (SMDs) between data sets. Results Among the 425 articles retrieved, 15 articles were considered eligible for narrative review, 8 articles were considered for single-arm meta-analysis, and 4 were included in a 2-arm meta-analysis. The mean lateral, global, depth, and angular deviations of the dental implant placed using AR navigation were 0.90 (95% CI 0.78-1.02) mm, 1.18 (95% CI 0.95-1.41) mm, 0.78 (95% CI 0.48-1.08) mm, and 3.96° (95% CI 3.45°-4.48°), respectively. The accuracy of AR navigation was significantly higher than that of the FH method (SMD=−1.01; 95% CI −1.47 to −0.55; P<.001) and CN method (SMD=−0.46; 95% CI −0.64 to −0.29; P<.001). However, the accuracies of the AR navigation and TG methods were similar (SMD=0.06; 95% CI −0.62 to 0.74; P=.73). Conclusions The positional deviations of AR-navigated implant placements were within the safety zone, suggesting clinically acceptable accuracy of the AR navigation method. Moreover, the accuracy of AR implant navigation was comparable with that of the highly recommended dental implant–guided surgery method, TG, and superior to that of the conventional FH and CN methods. This review highlights the possibility of using AR navigation as an effective and accurate immersive surgical guide for dental implant placement.
