AbstractTo determine the effect of customized vestibular exercise (VE) and optokinetic stimulation (OS) using a virtual reality system in patients with persistent postural-perceptual dizziness (PPPD). Patients diagnosed with PPPD were randomly assigned to the VE group or VE with OS group. All participants received VE for 20 min using a virtual reality system with a head mount display once a week for 4 weeks. The patients in the VE with OS group additionally received OS for 9 min. We analysed the questionnaires, timed up-to-go (TUG) test, and posturography scores at baseline and after 4 weeks. A total of 28 patients (median age = 74.5, IQR 66–78, men = 12) completed the intervention. From baseline to 4 weeks, the dizziness handicap inventory, activities of daily living (ADL), visual vertigo analogue scale, and TUG improved in the VE group, but only ADL and TUG improved in the VE with OS group. Patients with severe visual vertigo improved more on their symptoms than patients with lesser visual vertigo (Pearson’s p = 0.716, p < 0.001). Our VE program can improve dizziness, quality of life, and gait function in PPPD; however, additional optokinetic stimuli should be applied for individuals with visual vertigo symptoms.

Rehabilitation Training

Objective: To examine the effectiveness of rehabilitation training based on virtual reality in improving balance, quality of life, activities of daily living, and depressive symptoms of patients with Parkinson’s disease. Data sources: PubMed, EMBASE, CINAHL, Scopus, Cochrane Library, PsycINFO, ProQuest, Physiotherapy Evidence Database, IEEE Xplore, China National Knowledge Infrastructure, Wanfang, and VIP Information databases were searched from their inception to October 15, 2020. Trial registries, gray literature, and target journals were also searched. Methods: Eligible randomized controlled trials included studies with patients with Parkinson’s disease in rehabilitation training based on virtual reality. Comprehensive Meta-Analysis 3.0 software was used. Physiotherapy Evidence Database Scale and the Grading of Recommendation, Assessment, Development, and Evaluation system were used to assess the methodological quality of individual trials and the overall quality of the evidence, respectively. Results: A total of 22 randomized controlled trials with 836 patients were included. Meta-analysis revealed that training significantly improved balance ( g = 0.66, P < 0.001), quality of life ( g = 0.28, P = 0.015), activities of daily living ( g = 0.62, P < 0.001), and depressive symptoms ( g = 0.67, P = 0.021) compared to the control group. Subgroup analysis indicated that training should utilize video game consoles. Meta-regression analyses showed that age, sessions, and frequency of training had statistically significant impacts on balance scores. Quality of individual trials was high and overall evidence ranged from very low to low. Conclusion: Virtual rehabilitation training could be adopted in healthcare institutions as supplementary training for patients with Parkinson’s disease.

Vestibular dysfunction can have a tremendous impact on an individual’s quality of life. The purpose of this paper is to determine if the level of handicap reported by individuals on the Dizziness Handicap Inventory (DHI), an inventory developed for use with individuals with complaints of dizziness symptoms, will be consistent with that reported on the Activities-specific Balance Confidence Scale (ABC), a tool developed for use with elderly individuals that attempts to assess a person’s confidence level in performing activities of daily living (ADL’s). A sample of convenience was used consisting of 71 subjects (15 males and 56 females) from a local Balance and Vestibular Clinic. The subjects ranged in age from 26 to 88 years of age. Both the DHI and the ABC were administered as part of an initial physical therapy evaluation to new patients at the clinic. A moderately strong negative correlation was found between the scores of the two inventories ( r s = − 0.6350). The results suggest that the ABC is a valid tool for use with individuals with complaints of dizziness.

Underground square, as a recreation and activity place for citizens, represents the underground space quality of a city, so its spatial experience is of great significance. This research discussed the influence and effects of underground squares’ interface morphology on spatial experience. By field research of ten large-scale urban underground spaces, the basic elements and related numerical interval of underground squares’ interface morphology were summarized, and on basis of this, underground square virtual models with different interface morphology were built. Based on the platform of immersive virtual reality system (IVRS), combing the isovist method and the SD method, this paper made a quantitative analysis on the relevance between interface morphology and spatial experience, and the relevant compliance indicators of interface morphology were summarized. The experimental results show that the spatial experience is good at the interface density of 0.402 and interface opening’s aspect ratio of 2–3. This can provide reference and foundation for urban underground spatial design in future.

ABSTRACT Objective: To describe the intervention protocols to using commercial video games as virtual reality (VR) in rehabilitation of patients with stroke. Methods: Integrative review using the descriptors “rehabilitation”, “virtual reality exposure therapy” and “videogames” in the LILACS and PUBMED databases. Articles published from 2011 to 2018 were selected. Results: We found 1,396 articles, 1,383 were excluded and 13 were selected. Most of the articles were randomized clinical trials published in 2014 or later. The sample size varied from 5–47 adults, or adults and elders, with chronic stroke. The Nintendo Wii® was the most used video game system. The intervention happened two or three times a week, each session lasting from 30 to 60 minutes, over 2–12 weeks. Balance, upper limb motor functions, quality of life and daily living activities were the most common evaluated outcomes. The Fugl-Meyer Assessment, Berg Balance Scale, Timed Up and Go test, Barthel Scale and SF-36 were the most common outcome measurement tools. Conclusions: The studies indicated improvement in dynamic balance, upper limb motor function and quality of life after rehabilitation using VR. The VR was more effective than conventional treatments for the outcome of dynamic balance. Two studies did not find any changes in static balance and daily living activities. Physical aspects and quality of life were the outcomes most evaluated by the researchers; as were the population with chronic strokes and protocols of long duration and low intensity. Few studies targeted immediate VR effects, performance in daily living activities and social participation.

Functional Autonomy

(1) This review aims to evaluate the effectiveness of treatments with virtual reality systems (VRSs) on the functional autonomy of older adults versus conventional treatment. (3) Methods: Systematic review and meta-analysis. An electronic data search was carried out, following the PRISMA statement, up to February 2020. We combined results from clinical trials using VRSs for the improvement of basic and instrumental activities of daily living. The guidelines of the Cochrane Handbook for Systematic Reviews of Interventions were followed for calculations and risk of bias. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to assess the quality of evidence. (4) Results: The final analysis included 23 studies with a population of 1595 participants. A moderate, but clinically significant, effect was found for basic activities of daily living (BADLs), (Standard Medium Deviation, SMD 0.61; 95% CI: −0.15–1.37; P < 0.001). A small effect was found for instrumental ADLs (Instrumental Activities of daily living, IADLs) (SMD −0.34; 95% CI: −0.82–0.15; P < 0.001). Functional ambulation was the BADL which improved the most (SMD −0.63; 95% CI: −0.86, −0.40; P < 0.001). (5) Conclusion: The use of VRSs is an innovative and feasible technique to support and improve the functional autonomy of community-dwelling older adults. Due to the very low quality of the evidence for our main outcomes, the effects of a VRS on the BADLs and IADLs are uncertain. Clinical trials of a higher methodological quality are necessary to increase the level of knowledge of its actual effectiveness.
