Effect of virtual reality on upper limb function after stroke: a study of diffusion tensor imaging / 中国康复理论与实践

ObjectiveTo explore the effect of virtual reality on upper limb function in stroke patients through diffusion tensor imaging (DTI). MethodsFrom September, 2021 to March, 2023, 80 stroke patients in the Fuzhou Second General Hospital were randomly divided into control group (n = 40) and experimental group (n = 40). Both groups received routine rehabilitation, while the experimental group received virtual reality training additionally, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Action Research Arm Test (ARAT) before treatment, after treatment and after four-week follow-up; and they were scaned with DTI to measure the fractional anisotropy (FA) and relative anisotropy (RA) of cerebral peduncle and posterior limb of inner capsule of the affected side before and after treatment. ResultsTwo cases dropped in each group. The FMA-UE and ARAT scores increased in both groups after treatment and follow-up (F > 2.790, P < 0.001), and increased more in the experimental group than in the control group (t > 2.297, P < 0.05). FA and RA in the posterior limb of inner capsule increased in both groups after treatment (t > 21.013, P < 0.001), and increased more in the experimental group (t > 2.006, P < 0.05). The d-value of FA of the posterior limb of internal capsule before and after treatment (ΔFA) was positively correlated with the d-value of FMA-UE score (r > 0.362, P < 0.05) in both groups, the ΔFA of the posterior limb of internal capsule was positively correlated with the d-value of ARAT score (r = 0.459, P < 0.01). ConclusionVirtual reality training can promote the recovery of upper limb function in stroke patients, which may associate with the conductivity of posterior limb of inner capsule.

Multisensory Conflict Impairs Cortico-Muscular Network Connectivity and Postural Stability: Insights from Partial Directed Coherence Analysis / 神经科学通报·英文版

Sensory conflict impacts postural control, yet its effect on cortico-muscular interaction remains underexplored. We aimed to investigate sensory conflict's influence on the cortico-muscular network and postural stability. We used a rotating platform and virtual reality to present subjects with congruent and incongruent sensory input, recorded EEG (electroencephalogram) and EMG (electromyogram) data, and constructed a directed connectivity network. The results suggest that, compared to sensory congruence, during sensory conflict: (1) connectivity among the sensorimotor, visual, and posterior parietal cortex generally decreases, (2) cortical control over the muscles is weakened, (3) feedback from muscles to the cortex is strengthened, and (4) the range of body sway increases and its complexity decreases. These results underline the intricate effects of sensory conflict on cortico-muscular networks. During the sensory conflict, the brain adaptively decreases the integration of conflicting information. Without this integrated information, cortical control over muscles may be lessened, whereas the muscle feedback may be enhanced in compensation.

What do retina fellows-in-training think about the vitreoretinal surgical simulator: A multicenter survey

Purpose: To profile vitreoretinal (VR) fellows?in?training from India exposed to the Eyesi surgical simulator, to identify potential barriers to voluntary use, and enumerate the most preferred tools and tasks before incorporating them into a formal skill?transfer curriculum. Methods: A questionnaire consisting of 22 questions was designed and circulated through an online portal (surveymonkey.com) to four different institutes of India having a VR surgical fellowship program and using a functional Eyesi (Haag–Streit) simulator. All fellows and trainees who were exposed to the simulator were eligible to participate, irrespective of time spent on the simulator and exposure to training steps on real patients. The responses collected were private and anonymous. Results: Of the 37 respondents, most (n = 25, 68%) considered surgical simulators to be the best training tool before operating on the human eye. A majority (n = 35, 94.5%) of participants spent <3 h per week on the simulator, which, most (n = 30, 81%) felt was not enough time. The main reasons for this underutilization were work?hour limitations (54.8%), lack of a structured training program (19.3%), or a dedicated supervisor (16.1%). Again, the majority (n = 33, 89%) of participants responded that VR surgical skills acquired during simulator training were transferrable to the operating room, which was reflected by their response (n = 31, 83.7%) that simulator?based training should be made mandatory before operating room exposure. Conclusion: This study gives an insight into the overall practice patterns and preferences in simulation training of surgical VR fellows?in?training across India. It indicates that the simulator is extremely helpful to fellows and if adopted, VR surgical simulators with organized, directed, and supervised sessions will considerably improve the surgical training experience.

Objective: To investigate the effects of interventions using Virtual Reality (VR) for children with Cerebral Palsy (CP) based on the structure of the International Classification of Functioning, Health Disability (ICF). Method: This is a systematic review of randomized clinical trials, carried out in July 2022. Interventions related to physiotherapy associated with VR games for children with CP, aged 6 to 12 years, were investigated in the databases: PubMed, Cochrane, MedLine and PEDro. Methodological quality was assessed using the PEDro Scale. Nine studies were included involving a total of 310 participants, of which 5 were inserted in the structure and functions of the body, 9 articles in activity and no study investigated the participation component or contextual factors, and some were included in more than one component of the CIF. Results: Manual function and body balance were the most appreciated results. As a limitation, the small number of studies and the lack of data on participation components and contextual factors stand out. The strong point of the study was to associate an ICF with a physiotherapeutic rehabilitation category for this population. Conclusion: Recent experimental studies related to the use of VR in the physical therapy of children with CP are mostly focused on the activity component of the ICF. More studies are needed in order to investigate whether learning in the therapeutic environment is transferred in the context of these individuals' lives and whether there is an impact on participation and functionality.

Effect of virtual reality on preoperative anxiety in patients undergoing septorhinoplasty

Abstract Background The aim of this study was to evaluate the effect of a virtual reality video on preoperative anxiety, hemodynamic parameters, and patient satisfaction in patients undergoing septorhinoplasty. Methods This was a prospective, observational cohort trial. Forty patients between the ages of 18-65 who were scheduled for elective septorhinoplasty, with an American Society of Anesthesiologists (ASA) physical status I-II were included in the study. Patients experienced a 15-minute virtual reality (VR) video via a phone using a VR device. A three-dimensional, 360° video depicted the beauty of nature and was accompanied by meditation music. Patients' oxygen saturation values, heart rate, and blood pressure were monitored and recorded. Using the State-Trait Anxiety Inventory scale, anxiety scores and hemodynamic parameters were compared before and after VR application. Results Median anxiety scores decreased significantly from 40.5 to 34 (p< 0.001). VR also had positive effects on hemodynamic parameters. Conclusions VR reduces preoperative anxiety and has positive effects on hemodynamic parameters in patients undergoing septorhinoplasty. We anticipate that VR will be increasingly used as a non-pharmacological preoperative approach in the future.

Efeitos de um treinamento com dispositivo comercial de realidade virtual imersiva sobre a marcha e cognição de pessoas com doença de Parkinson / Effects of a commercial immersive virtual reality device-based training on gait and cognition in people with Parkinson's disease

Objetivo: Avaliar a eficácia e a usabilidade de um treinamento imersivo de realidade virtual usando o Samsung Gear VR OculusTM (SGVR) para marcha e cognitivo em pessoas com doença de Parkinson (DP). Foi realizado um ensaio clínico controlado, quase experimental e cego. Método: Quarenta pessoas com DP foram divididas em dois grupos. O Samsung Gear Virtual Reality Group (VRG) participou de 10 sessões, duas vezes por semana, com duração de uma hora cada, realizando quatro jogos que exigiam movimento da cabeça e deslocamento do centro de gravidade. O grupo controle não recebeu tratamento. Os participantes foram avaliados antes, após a intervenção e 30 dias após a intervenção, com avaliação da marcha por meio do teste Timed Up and Go, teste de caminhada de 10 metros, teste de caminhada de 30 segundos com tarefa simples e dupla e avaliação cognitiva com teste de fluência verbal, dígito para frente e para trás Testes de amplitude e teste Stroop Color. Ao final do treinamento, a VRG respondeu ao questionário System Usabilidade Scale para avaliar a usabilidade do sistema. Resultados: Embora o sistema tenha sido avaliado com excelente usabilidade pelos usuários, não houve efeitos de interação e, portanto, nossos resultados não suportam que o treinamento de realidade virtual imersiva usando jogos SGVR foi superior a nenhum treinamento. Conclusão: No entanto, quando cada grupo foi examinado separadamente, o VRG apresentou melhoras, após a intervenção e 30 dias após a intervenção, para velocidade da marcha (p<0,005 e p<0,001, respectivamente), memória de trabalho, atenção e processamento de informações (p<0,01 em ambos os momentos de avaliação), inibição de resposta, memória de trabalho e de longo prazo (p< 0,01 em 30 dias após a intervenção). A avaliação adicional do dispositivo SGVR é necessária

Objective: Evaluate the effectiveness and the usability of an immersive virtual reality training using Samsung Gear VR OculusTM (SGVR) for gait and cognitive in people with Parkinson's disease (PD). Controlled, quasi-experimental and blinded clinical trial was carried out. Methods: Forty people with PD were divided into two groups. Samsung Gear Virtual Reality Group (VRG) participated in 10 sessions, twice a week, lasting one hour each, performing four games that required head movement and center of gravity shift. Control group didn't receive treatment. Participants were evaluated before, after the intervention and 30 days after intervention, with the Timed Up and Go test, 10 meters walking test, single and dual tasking 30 seconds walking test, verbal fluency test, forward and backward Digit Span tests and Stroop Color test. At the end of the training, VRG responded to the System Usability Scale questionnaire to assess the usability of the system. Results: Even though the system was rated with excellent usability by the users, there were no interaction effects and, therefore, our results do not support that immersive virtual reality training using SGVR games was superior to no training. However, when each group was examined separately, the VRG experienced improvements, after the intervention and 30 days after intervention, for gait velocity (p<0.005, p<0.001, respectively), working memory, attention, and information processing (p<0.01 in both evaluation time points), response inhibition, working and long-term memory (p< 0.01 in 30 days after intervention). Conclusion: Further evaluation of the SGVR device is required

The use of serial casting in the treatment of children with cerebral palsy: a study protocol

Introduction: Cerebral Palsy (CP) is characterized by a disorder of posture and movement, commonly leading to disabling orthopedic alterations, including muscle shortening, especially in the lower limbs. Stretching methods, performed gradually, are necessary to delay the impairment in function from muscle shortening. The use of serial casting aims to promote proper alignment, and an ideal and stable support base, in addition to better bone and joint health, leading to better posture, mobility, muscle function, and, subsequently, increased fitness and health.Objective: evaluate range of motion, postural control, and motor performance in children with CP, using serial casting, as well as to measure its effect on fitness through the autonomic nervous system (ANS).Methods: Sixty children and adolescents with CP, of both sexes, 3 to 12 years of age, will be divided into three groups: Groups A, B, and C, with 20 individuals each. Group A will use serial casting, Group B will use the orthosis continuously (with removal only allowed for bathing), and Group C will use the orthosis in their daily routine. Range of motion of the ankle of first and second resistance levels (R1 and R2), gross motor function measure (GMFM), and balance (measured by BERG scale) will be used in the initial and final assessments, and after 6 months and one year of follow-up. Timed-up-and-go (TUG), load distribution (baropodometry), motor performance measured through a real basketball game and the virtual MoveHero game, analysis of body angulation with "mydartfish", and cardiac autonomic modulation through heart rate variability will be assessed in three different situations: barefoot, with orthosis, and with casting.Conclusion: Serial casting demonstrates the potential to produce positive results in the treatment of individuals with CP regarding better alignment, with consequent motor and autonomic improvement.

The effect of virtual reality technology in children after surgery for concomitant strabismus

Purpose: This study aimed to investigate the effect of virtual reality (VR) technology in children after surgery for concomitant strabismus. Methods: A total of 200 children with concomitant exotropia or concomitant esotropia were randomly divided into a training group and a control group according to the single even number random method (100 cases in each group). Patients in the training group received VR intervention training within 1 week after surgery. Patients in the control group did not receive any training. Results: Six months after the surgery, the orthophoria (the far or near strabismus degree was ?8?) rate was significantly higher in the training group than in the control group (P = 0.001), while the eye position regression rate (compared to the strabismus degree within 1 week after the surgery, the amount of regression >10?) was significantly lower in the training group than in the control group (P = 0.001). Six months after the surgery, the number of children with simultaneous vision and remote stereovision was significantly higher in the training group than in the control group (P = 0.017 and 0.002, respectively). The differences in the number of patients with peripheral stereopsis, macular stereopsis, and stereopsis in macular fovea centralis at 1, 3, and 6 months after the surgery between the training and the control groups were not statistically significant (P = 0.916, 0.274, and 0.302, respectively). Conclusion: The intervention of VR technology after strabismus correction effectively improved children’s visual function and maintained their eye position

Applicability of an immersive virtual reality system to assess egocentric orientation of older adults / Aplicabilidade de um sistema de realidade virtual imersivo para avaliar a orientação egocêntrica de idosos

Abstract Background Spatial orientation is a cognitive domain frequently compromised in patients with Alzheimer disease (AD) and may be one of its first clinical manifestations. Some studies have shown that allocentric integration with egocentric spatial information seems to be impaired in this pathology. There is no consensus on how best to assess spatial orientation and traditional tests lack ecological validity, but, recently, virtual reality (VR) has provided new opportunities for this assessment. Objectives To analyze the applicability and stability of an immersive virtual task developed to assess spatial orientation, the Spatial Orientation in Immersive Virtual Environment Maze Test (SOIVET-Maze) in older adults with and without mild cognitive impairment. Methods Forty-three older adults were included in the study, 24 without cognitive impairment and 19 with mild cognitive impairment. Applicability was assessed by the Witmer and Singer Sense of Presence Questionnaire and a questionnaire for adverse events of cybersickness. To assess stability, participants were assessed twice with an interval of 7 to 14 days, and the intraclass correlation coefficient was calculated between visits. The t test or the Mann-Whitney test was used to compare applicability and stability between groups. Results There was no significant difference between the groups regarding applicability. A strong correlation between the first and second day of testing was found in the mild cognitive impairment group. Conclusion The SOIVET-Maze task showed excellent applicability and good stability, favoring its clinical application for the evaluation of spatial orientation in older adults.

Resumo Antecedentes A orientação espacial é um domínio cognitivo frequentemente comprometido em pacientes com doença de Alzheimer (DA) e pode ser uma das suas primeiras manifestações clínicas. Alguns estudos demonstraram que a integração alocêntrica com informações espaciais egocêntricas parece prejudicada nessa patologia. Não há um consenso sobre qual a melhor forma de avaliar a orientação espacial e os testes tradicionais carecem de validade ecológica; porém, recentemente, a realidade virtual (RV) proporcionou novas oportunidades para esta avaliação. Objetivos Analisar a aplicabilidade e estabilidade de uma tarefa virtual imersiva desenvolvida para avaliar a orientação espacial, o Spatial Orientation in Immersive Virtual Environment Maze Test (SOIVET-Maze) em idosos com e sem comprometimento cognitivo leve. Métodos Quarenta e três idosos foram incluídos no estudo, 24 sem comprometimento cognitivo e 19 com comprometimento cognitivo leve. A aplicabilidade foi avaliada pelo Witmer and Singer Sense of Presence Questionnaire e um questionário para eventos adversos de cybersickness. Para avaliar a estabilidade, os participantes foram avaliados 2 vezes com intervalo de 7 a 14 dias, e o coeficiente de correlação intraclasse foi calculado entre as visitas. O teste t ou o teste de Mann-Whitney foi utilizado para comparar a aplicabilidade e estabilidade entre os grupos. Resultados Não houve diferença significativa entre os grupos quanto à aplicabilidade. Uma forte correlação entre o primeiro e o segundo dia de teste foi encontrada no grupo de comprometimento cognitivo leve. Conclusão A tarefa SOIVET-Maze apresentou excelente aplicabilidade e boa estabilidade, favorecendo sua aplicação clínica para avaliação da orientação espacial em idosos.

Intervenciones cognitivas a través de realidad virtual en personas con Deterioro Cognitivo Leve: Una Revisión Sistemática

Introducción: La posibilidad de reversión del Deterioro Cognitivo Leve (DCL) ha generado diversas investigaciones en búsqueda de tratamiento, entre ellas la estimulación cognitiva a través de realidad virtual (RV). No obstante su uso, no existe aún evidencia acerca de las modalidades y efectos en personas con DCL. Objetivo: Sistematizar las características de los estudios que han utilizado intervenciones cognitivas con RV en personas con DCL, describir sus efectos y establecer recomendaciones para futuras investigaciones en base a las limitaciones reportadas. Métodos: revisión sistemática de estudios publicados entre 2010 y 2020, en las bases de datos Web of Science, Scopus y Pubmed. Resultados: Se identificaron 14 estudios con programas que emplearon mayoritariamente RV de tipo inmersiva, con el "supermercado" como escenario virtual más frecuente. En siete trabajos se intervino una función cognitiva, siendo la memoria y las funciones ejecutivas las más intervenidas. Los instrumentos de evaluación se concentraron en medidas cognitivas, con escasa evaluación de variables neuropsiquiátricas y de calidad de vida. Trece estudios informaron mejoras a nivel cognitivo general o por dominio específico. Conclusiones: La utilización de RV, inmersiva y no inmersiva, ha tenido resultados positivos en el rendimiento cognitivo general o específico por dominio, de personas con DCL, sin embargo, debido a la incipiente y limitada evidencia de su uso en personas con esta patología, no es posible determinar la sostenibilidad de estos resultados y la generalización de estas intervenciones hacia las actividades de la vida diaria. Se recomienda realizar intervenciones con entornos reales y seguimiento post-intervención.

Introduction: The possibility of Mild Cognitive Impairment (MCI) reversal has generated numerous studies in search of treatment, including cognitive stimulation through virtual reality (VR). Despite its use, there is still no evidence about the modalities and effects in people with MCI. Aim: To systematize the characteristics of the studies that have used cognitive interventions with VR cognitive in people with MCI, describe their effects and to establish recommendations for future research based on the limitations reported. Methods: systematic review of studies published between 2010 and 2020, in the Web of Science, Scopus and Pubmed databases. Results: 14 studies were identified with programs that mostly used immersive VR, with the "supermarket" as the most frequent virtual scenario. In seven studies only one cognitive function was involved, with memory and executive functions being the most intervened. The assessment instruments focused on cognitive measures, with little assessment of neuropsychiatric and quality of life variables. Thirteen studies reported improvements on the general cognitive level or by specific domain. Conclusions: The use of immersive and non-immersive VR has had positive results in the general or domain-specific cognitive performance of people with MCI, however, due to the incipient and limited evidence of its use in people with this pathology, it is not possible to determine the sustainability of these results and the generalization of these interventions regarding daily living activities. Interventions with real environments and post-intervention follow-up are recommended.

In order to enrich channels of psychological health education of college students, the paper summarizes the methods, advantages and future direction of its application in promoting mental health of college students, providing reference for expanding the intervention ways of college students psychological health education and promotion.

A Virtual Reality Platform for Context-Dependent Cognitive Research in Rodents / 神经科学通报·英文版

Animal survival necessitates adaptive behaviors in volatile environmental contexts. Virtual reality (VR) technology is instrumental to study the neural mechanisms underlying behaviors modulated by environmental context by simulating the real world with maximized control of contextual elements. Yet current VR tools for rodents have limited flexibility and performance (e.g., frame rate) for context-dependent cognitive research. Here, we describe a high-performance VR platform with which to study contextual behaviors immersed in editable virtual contexts. This platform was assembled from modular hardware and custom-written software with flexibility and upgradability. Using this platform, we trained mice to perform context-dependent cognitive tasks with rules ranging from discrimination to delayed-sample-to-match while recording from thousands of hippocampal place cells. By precise manipulations of context elements, we found that the context recognition was intact with partial context elements, but impaired by exchanges of context elements. Collectively, our work establishes a configurable VR platform with which to investigate context-dependent cognition with large-scale neural recording.

Impact of different kinds of helmet-mounted display on human balance and posture control / 中国康复理论与实践

ObjectiveTo explore the impact of different types of virtual reality environments balance exercise on human balance and posture control. MethodsFrom March to April, 2022, 30 male students from Dalian University of Technology were recruited to accept VR balance training of dynamic background (dynamic VR training) and static background (static VR training), respectively, with an interval of one week. They were measured the average moving speed of the center of pressure of human body under eight conditions before and after training, namely open-eye floor standing, close-eye floor standing, static VR background floor standing, dynamic VR background floor standing, open-eye sponge pad standing, close-eye sponge pad standing, static VR background sponge pad standing, and dynamic VR background sponge pad standing. Meanwhile, the weight of human body sensation was calculated. ResultsBefore training, the average movement speed of center of pressure was higher under the static VR than under open-eye (|t| > 2.811, P < 0.01), and lower than under close-eye (t > 3.279, P < 0.01) on both planes; while it was higher under dynamic VR than under close-eye (|t| > 4.830, P < 0.001). After dynamic VR training, the average movement speed of center of pressure increased under open-eye stable floor standing (t = 2.305, P < 0.05), decreased under close-eye on both planes (t > 3.405, P < 0.01), and decreased under static and dynamic VR on both planes (|t| > 3.285, P < 0.01). After static VR training, the average movement speed of center of pressure increased under open-eye floor standing (t = 2.224, P < 0.05), decreased under close-eye sponge pad standing (t = 2.223, P < 0.05), and decreased under dynamic VR on both planes (|t| > 2.380, P < 0.05). The weight of vision decreased after training (t > 4.132, P < 0.001), and the visual weight under normal proprioception was less after dynamic VR training than after static VR training (t = 3.611, P < 0.01). ConclusionUnder static VR background, the balance stability is poorer than under open-eye, but stronger than under close-eye. Under dynamic VR background, the balance stability is poorer under close-eye. VR balance training may decrease the stability without interference, but improve the stability under interference, which may result from reducing the dependence on visual sensation and strengthening the use of vestibular sensation, especially after VR training with dynamic background.

A formação inventiva em terapia ocupacional em tempos de COVID-19: a presença na virtualidade / Inventive education in occupational therapy in times of COVID-19: presence in virtuality

Resumo Objetivo O artigo se propõe a analisar o ensino remoto no contexto universitário em tempos de pandemia na perspectiva de docentes que trabalham com a formação inventiva. Centra-se em experiências teórico-práticas de três universidades do Brasil e do Chile. Método Utilizou-se o relato de experiência como método para esta pesquisa, o que permitiu a análise do processo formativo com base nas disciplinas vivenciais de maneira remota. Resultados A formação inventiva contribuiu nos processos de comunicação, de conhecimento de si e do outro e na promoção do trabalho grupal entre os estudantes. Por meio das atividades artísticas e corporais foi possível evidenciar alguns desafios relacionados a questões estruturais, virtuais, curriculares e culturais. Estimular o envolvimento e o estudo de experiências artísticas e corporais, especialmente com estudantes, pode auxiliar o processo da transversalidade com as práticas em terapia ocupacional, possibilitando sua participação em territórios desconhecidos, mobilizando afetos e criando espaços capazes de agenciar diversas formas de contato e aproximação, trabalhando e fortalecendo aspectos pessoais e sociais. Conclusão Foram evidenciadas situações distintas entre as três universidades onde a formação inventiva possibilitou aos docentes e estudantes uma aproximação de suas atividades cotidianas, estimulando o processo de comunicação, de conhecer a si e conhecer o outro, além de promover o trabalho grupal. No entanto, fica evidenciado que o ensino remoto não substitui as aulas presenciais e que, apesar de todas as dificuldades, os docentes terapeutas ocupacionais facilitaram o processo de adaptar-se às realidades em contextos possíveis.

Abstract Objective This study aims to analyze remote teaching in the university context in times of pandemic from the perspective of teachers who work with inventive education. It focuses on theoretical-practical experiences conducted in three universities in Brazil and Chile. Method The experience report was used as a method in this research, enabling analysis of the education process based on experiential disciplines taught remotely. Results Inventive education contributed to the processes of communication, knowledge of oneself and the other, and the promotion of group work among students. Through artistic and bodily activities, some challenges related to structural, virtual, curricular, and cultural issues could be highlighted. Modulating the involvement and study of artistic and bodily experiences, especially with students, can assist in the process of transversality in occupational therapy practices, enabling their participation in unknown territories, mobilizing affections and creating spaces capable of managing different forms of interaction, contact and approximation, working and strengthening personal and social aspects. Conclusion Different situations were evidenced between the three universities where the inventive education allowed teachers and students to approach their everyday activities, stimulating the process of communication, knowing oneself and the other, and promoting group work. However, it is evident that remote teaching does not replace face-to-face classes and that, despite all the difficulties, occupational therapy teachers facilitated the process of adapting to realities in possible contexts.
