Abstract
Objective To systematically evaluate the effectiveness of virtual reality (VR) in the rehabilitation of patients with functional ankle instability (FAI). Methods Nine databases were researched, including PubMed, Cochrane Library, Web of Science, Embase, OVID, CNKI, VIP, WanFang, SinoMed, ResearchGate, and WorldWildScience. The publication date deadline was May 22, 2021. To analyze the effect of VR rehabilitation of FAI, we systematically reviewed the literature using the RevMan 5.4 software. Main Results. Five randomized controlled trials (RCTs) were included in the analysis, consisting of 137 patients with FAI; 68 of them were in the experimental group, 69 were in the control group, and all were university students. A comparison study was conducted between the two groups in terms of balance function, muscle performance, and proprioception. VR rehabilitation in the treatment of FAI was found to be significantly more effective using a 30-second single-leg standing test than conventional rehabilitation. The angular offset index of VR rehabilitation training was significantly lower than that of conventional balance training (0.66 ± 0.18 vs. 0.95 ± 0.21; P = 0.005). Conclusion VR rehabilitation is effective at treating FAI. However, RCTs with higher homogeneity are needed to provide a more reliable evidence-based foundation for clinical rehabilitation.
Highlights
By comparing the use of treadmill training and virtual reality (VR) postural adjustment fusion training with the balance trainer and aero-step, we found a reduction in the 60-second standing balance test in the area of foot pressure movement (P < 0.05), the distance moved (P < 0.001), and an increase in the stability limit (P < 0.05) in the VR group, indicating a significant increase of the plantar center of pressure control. e differences in these indicators between the VR-based training group and the treadmill training group were statistically significant [28]
Since the VR system is used at home, it can be considered beneficial for the continuous rehabilitation management of patients in the long run [33]
Based on the five included randomized controlled trials (RCTs) on rehabilitation training of patients with functional ankle instability (FAI), this study summarized the effects of VR rehabilitation on balance function, proprioception, and muscle strength. e results showed that the effect of VR rehabilitation training on improving ankle function, in terms of ankle proprioception [26], Y-balance test [26], 30-second single-leg standing balance test [26], Romberg’s test [26], 60-second standing balance test [28], CMJA [28], SLJ [28], and other indicators, is significantly better than that of conventional balance training or treadmill training
Summary
Nine databases were searched, including PubMed, Cochrane Library, Web of Science, Embase, OVID, CNKI, VIP, WanFang, SinoMed, ResearchGate, and WorldWildScience. E publication date deadline for literature retrieval was May 22, 2021. The gray literature was searched by tracking the references of the relevant studies and conducting manual retrieval. Two authors (HY and KY) independently completed literature screening, data extraction, and crosschecking of results. The titles and abstract contents were read for preliminary screening, and the full texts were read to determine whether the literature met the inclusion criteria. E Korean studies were translated into English by professional translators in related fields, followed by reading of the full text and extracting the data. If any discrepancies were encountered, they were discussed and solved by contacting the corresponding author (B.)
