Discusión : Esta herramienta de detección pue de respaldar el diagnóstico del TEA al reforzar los resultados de los procedimientos tradicionales de evaluación.

Abstract Introduction : Autism Spectrum Disorder (ASD) is a neurodevelopmental condition which traditional as sessment procedures encounter certain limitations. The current ASD research field is exploring and endorsing innovative methods to assess the disorder early on, based on the automatic detection of biomarkers. How ever, many of these procedures lack ecological validity in their measurements. In this context, virtual reality (VR) shows promise for objectively recording biosignals while users experience ecological situations. Methods : This study outlines a novel and playful VR procedure for the early assessment of ASD, relying on multimodal biosignal recording. During a VR experience featuring 12 virtual scenes, eye gaze, motor skills, elec trodermal activity and behavioural performance were measured in 39 children with ASD and 42 control peers. Machine learning models were developed to identify digital biomarkers and classify autism. Results : Biosignals reported varied performance in detecting ASD, while the combined model resulting from the combination of specific-biosignal models demon strated the ability to identify ASD with an accuracy of 83% (SD = 3%) and an AUC of 0.91 (SD = 0.04). Discussion : This screening tool may support ASD diagnosis by reinforcing the outcomes of traditional assessment procedures.

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.

Miedo a las alturas en mareo postural perceptual persistente en ambientes arquitectónicos simulados por realidad virtual

Introducción: El mareo postural perceptual persistente (MPPP) es una de las causas más frecuentes de vértigo crónico. Si bien, los pacientes con MPPP tienen alteraciones de la percepción espacial, se desconoce si presentan alteraciones en el miedo a las alturas. Para no exponer a pacientes con MPPP a ambientes reales con altura, nos propusimos utilizar la realidad virtual para estudiar el miedo a las alturas. Objetivo: Cuantificar el miedo a las alturas en pacientes con MPPP y controles mediante ambientes simulados con realidad virtual. Material y Método: Estudio transversal, prospectivo de casos y controles pareados por edad y sexo. Se reclutaron pacientes con MPPP del Servicio de Otorrinolaringología del Hospital Clínico de la Universidad de Chile entre los años 2020 y 2021. Se midió presencia subjetiva de miedo y taquicardia. Los escenarios se desarrollaron con el programa Blender 2.8 y Oculus Link para equipo Oculus Quest. Se utilizaron cinco escenarios a diferentes alturas (pisos 1, 3, 6, 12, 19). Resultados: Se reclutaron 20 sujetos (12 mujeres, 47 años en promedio), incluyendo 10 pacientes con MPPP y 10 controles sin síntomas vestibulares. Ningún sujeto del grupo control presentó miedo en los escenarios presentados, mientras que siete pacientes del grupo MPPP tuvieron miedo subjetivo a una altura menor a 40 metros virtuales (Fischer, p < 0,05). Conclusión: Los pacientes con MPPP presentan, con mayor frecuencia, miedo subjetivo a las alturas que los controles, pero se requiere de nuevos estudios para determinar si este miedo es específico de MPPP, o es general a otras causas de vértigo crónico.

Introduction: Persistent Postural Perceptual Dizziness (PPPD) is one of the most common causes of chronic vertigo. While patients with PPPD have spatial perception alterations, it is unknown whether they present alterations in fear of heights. To avoid exposing patients with PPPD to high places, we aimed to use virtual reality to quantify fear of heights. Aim: To quantify fear of heights in patients with PPPD and controls using simulated environments with virtual reality. Material and Method: A prospective cross-sectional study of age- and sex-matched case-control pairs. PPPD patients were recruited from the Otolaryngology Service of the Clinical Hospital of the University of Chile between 2020 and 2021. Presence of subjective fear and tachycardia were measured. The scenarios were developed using Blender 2.8 and Oculus Link for the Oculus Quest. Five scenarios at different heights (floors 1, 3, 6, 12, 19) were used. Results: Twenty subjects were recruited (12 women, average age of 47 years), including 10 PPPD patients and 10 controls without vestibular symptoms. None of the control group subjects presented fear in the presented scenarios, while seven patients in the PPPD group had subjective fear at a height lower than virtual 40 meters (Fischer, p < 0.05). Conclusion: Patients with PPPD present a greater proportion of subjective fear to heights than controls, but further studies are required to determine if this fear is specific to PPPD or is general to other causes of chronic vertigo.

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.

RESUMEN Los simuladores de realidad virtual háptico (RVH) están tomando cada vez más alcance en la educación clínica moderna. En este proceso se evidencia la importancia de la retroalimentación que el instructor brinda a los estudiantes, que puede darse de manera presencial o remota, esta última con ayuda de un sistema de audio y micro individualizado. No obstante, existe poca literatura que haya explorado y evidenciado las ventajas y desventajas de estas dos formas. Objetivo: Determinar el efecto que tiene la retroalimentación remota vs. presencial en el proceso de adquisición de destreza manual utilizando un simulador de RVH en estudiantes de primer año de la Facultad de Estomatología de la Universidad Peruana Cayetano Heredia. Material y Métodos: Se realizó un estudio en 37 participantes (X = 18,2 años; DS = 3,2 años), sin entrenamiento dental previo. Fueron asignados aleatoriamente en tres grupos (n1 = 17; n2 = 10; n3 = 10). El grupo 1 recibió solo retroalimentación presencial; el grupo 2 recibió solo retroalimentación remota; y el grupo 3 no recibió ningún tipo de retroalimentación. Los tres grupos debían completar el mismo ejercicio durante el mismo tiempo asignado. Resultados: Se encontraron diferencias significativas entre los grupos en el rendimiento general, incluyendo intentos fallidos y exitosos; sin embargo, no hubo diferencia entre el tiempo y el número de intentos realizados durante la práctica. Conclusiones: La adquisición de destreza manual utilizando ejercicios básicos dentales por estudiantes novatos es optimizada a través de una retroalimentación remota con el uso de un simulador de RVH.

ABSTRACT Haptic Virtual Reality (HVR) simulators are increasingly crucial in modern clinical education. Within this context, the significance of feedback provided by instructors to students is evident. This feedback can be delivered either face-to-face or remotely, the latter facilitated by an individualized audio and microphone system. However, there is limited literature exploring and illustrating the advantages and disadvantages of these two approaches. Objective: To determine the impact of remote vs. face-to-face feedback on the process of acquiring manual dexterity using an HVR simulator among first-year students at the School of Stomatology of Universidad Peruana Cayetano Heredia. Material and methods: A study was conducted involving 37 participants (mean age = 18.2 years; SD = 3.2 years) without prior dental training. They were randomly assigned to three groups (n1 = 17; n2 = 10; n3 = 10). Group 1 received only face-to-face feedback; Group 2 received exclusively remote feedback; and Group 3 received no feedback. All three groups were required to complete the same exercise within the same designated time frame. Results: Significant differences were observed among groups in overall performance, encompassing both unsuccessful and successful attempts. However, there was no distinction in terms of the time taken or the number of attempts made during practice. Conclusions: The acquisition of manual dexterity among novice dental students through basic exercises is optimized by utilizing remote feedback in conjunction with an HVR simulator.

RESUMO Os simuladores de realidade virtual háptica (RVH) estão ganhando crescente relevância na educação clínica moderna. Nesse contexto, torna-se cada vez mais evidente a importância do feedback fornecido pelos instrutores aos alunos, seja de forma pessoal ou remota. No segundo caso, a utilização de um sistema de áudio e microfone individualizado auxilia nesse processo. No entanto, é notável a escassez de literatura que tenha explorado e evidenciado as vantagens e desvantagens dessas duas abordagens. Objetivo: O presente estudo tem como objetivo determinar o impacto do feedback remoto em comparação com o feedback presencial no processo de aquisição de destreza manual utilizando um simulador de RVH. O estudo foi conduzido com alunos do primeiro ano da Faculdade de Estomatologia da Universidad Peruana Cayetano Heredia. Material e métodos: Participaram do estudo 37 alunos (média de idade = 18,2 anos; desvio padrão = 3,2 anos), sem experiência prévia em odontologia. Os participantes foram distribuídos aleatoriamente em três grupos: Grupo 1 (n1 = 17) recebeu somente feedback presencial; Grupo 2 (n2 = 10) recebeu exclusivamente feedback remoto; e o Grupo 3 (n3 = 10) não recebeu nenhum tipo de feedback. Todos os três grupos realizaram o mesmo exercício no mesmo período de tempo determinado. Resultados: Foram encontradas diferenças significativas entre os grupos no desempenho geral, incluindo tanto tentativas fracassadas quanto bem-sucedidas. No entanto, não foram observadas diferenças significativas em relação ao tempo e ao número de tentativas realizadas durante a prática. Conclusões: Os resultados deste estudo indicam que a aquisição de destreza manual por parte de alunos novatos, ao executarem exercícios odontológicos básicos, é otimizada por meio do uso de feedback remoto proporcionado por um simulador de RVH.

Objetivo: Investigar os efeitos das intervenções com uso de Realidade Virtual (RV) para crianças com Paralisia Cerebral (PC) baseando-se na estrutura da Classificação Internacional de Funcionalidade, Incapacidade de Saúde (CIF). Método: Trata-se de revisão sistemática de ensaios clínicos randomizados, realizada em julho de 2022. Foram investigadas intervenções relacionadas a fisioterapia associada aos jogos de RV para crianças com PC, idade de 6 a 12 anos nas bases de dados: PubMed, Cochrane, MedLine e PEDro. A qualidade metodológica foi avaliada pela Escala PEDro. Foram incluídos 9 estudos envolvendo total de 310 participantes, destes, 5 estavam inseridos em estrutura e funções do corpo, 9 artigos em atividade e nenhum estudo investigaram o componente participação ou fatores contextuais, sendo que alguns foram incluídos em mais do que um componente da CIF. Resultados: A função manual e o equilíbrio corporal foram os desfechos mais avaliados. Como limitação, destaca-se o pequeno número de estudos e a falta de dados sobre os componentes de participação e fatores contextuais. O ponto forte do estudo foi associar a CIF a uma categoria de reabilitação fisioterapêutica para esta população. Conclusão: Pesquisas experimentais recentes relacionadas ao uso da RV na fisioterapia de crianças com PC estão em sua maioria direcionadas ao componente de atividade da CIF. Mais estudos são necessários a fim de investigar se o aprendizado no ambiente terapêutico é transferido no contexto de vida desses indivíduos e se há impacto na participação e funcionalidade.

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 article is part of the 2021 postdoctoral research Contribution to the history of analytical psychology through the eyes of Léon Bonaventure based on interviews with him and his texts. The insertion of the analytical psychology in Brazil through the pioneers Nise da Silveira in mental health, Pethö Sandor with the physiopsychic integration and Léon Bonaventure at the clinic emphasizing the reality of the soul reflects the interdisciplinary dialogue present in the construction of the conception. Psychotherapist, researcher and editor responsible for the transmission of Jungian work in Brazil, based on the existence of the soul per se - subject and object of psychological knowledge - Bonaventure highlights it as a matrix of experiences, presents the way of knowing it, discusses the presence of the typology in the authors' production. He thematizes the notion of the Self, based on the writings of the mystic Teresa of Ávila and compares the understanding of the soul and its center to that of Jung. As a "gardener of the soul", he approached it as experience and reality, in a symbolic attitude.

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.

Objetivo: Comparar os efeitos dos exercícios por realidade virtual (RV)com o exercício físico convencional para as capacidades cognitivas e psicológicas das pessoas idosas. Métodos: Incluídos artigos publicados entre 2012 e 2021, das bases de dados PubMed, Scielo, Cochrane Library e Web of Science. Critérios de inclusão: estratégia PICO (Participante, Intervenção, Comparação e Outcome/Desfecho; RoB 2- Cochrane para analisar o risco de viés para ensaios randomizados; GRADE Pro, avaliação da qualidade das evidências. Resultados e discussão: 403 artigos inicialmente identificados, 23 elegíveis para a revisão sistemática e 14 incluídos na metanálise. Instrumentos encontrados: Trail Making Test (TMT-B), Stroop Test, Montreal Cognitive Assessment (MoCA), Mini Exame do Estado Mental (MEEM) e Short Form Health Survey (SF-36). No TMT-B observamos heterogeneidade (Tau²=0,51, I²=82,97%, Q=17,51, p=0,001) e diferença estatisticamente significativa entre os grupos, favorecendo a intervenção por RV (p=0,028). No Stroop Test, não observamos heterogeneidade (Tau²=0, I²=0, Q=1,53, p=0,464) e não houve diferença entre os grupos (p=0,194). Nos testes MEEM e MoCA, tivemos heterogeneidade entre os grupos (Tau²=0,17, I²=63,47%, Q=18,055, p=0,012), favorecendo a RV de maneira estatisticamente significativa (p=0,008). O SF-36 não apresentou heterogeneidade entre os grupos (Tau²=0, I²=0, Q=1,53, p=0,464) e não houve diferença estatística significativa (0,657). Conclusão: Ainda não é possível afirmar que apenas a utilização da RV é eficiente, porém ressaltamos que as intervenções realizadas com as pessoas idosas, nas quais eles se sentem parte e são responsáveis pelo seu desempenho, mostram a interação e motivação para o exercício físico, ajudando a terem uma vida mais saudável e com mais qualidade.

Objective: To compare the effects of virtual reality (VR) exercises with conventional physical exercise on the cognitive and psychological capabilities of older people. Methods: Included articles published between 2012 and 2021, from the PubMed, Scielo, Cochrane Library and Web of Science databases. Inclusion criteria: PICO strategy (Participant, Intervention, Comparison and Outcome/Outcome and; RoB 2- Cochrane to analyze the risk of bias for randomized trials; GRADE Pro, assessment of the quality of evidence. Results and discussion: 403 articles initially identified, 23 eligible for the systematic review and 14 included in the meta-analysis. Instruments found: Trail Making Test (TMT-B), Stroop Test, Montreal Cognitive Assessment (MoCA), Mini Mental State Examination (MMSE) and Short Form Health Survey (SF-36). In TMT-B we observed heterogeneity (Tau²=0.51, I²=82.97%, Q=17.51, p=0.001) and a statistically significant difference between the groups, favoring the VR intervention (p=0.028). In the Stroop Test, we did not observe heterogeneity (Tau²=0, I²=0, Q=1.53, p=0.464) and there was no difference between the groups (p=0.194). In the MMSE and MoCA tests, we had heterogeneity between the groups (Tau²=0.17, I²=63.47%, Q=18.055, p=0.012), favoring VR in a statistically significant way (p=0.008). The SF-36 showed no heterogeneity between groups (Tau²=0, I²=0, Q=1.53, p=0.464) and there was no statistically significant difference (0.657). Conclusion: It is not yet possible to say that the use of VR alone is efficient, however we emphasize that interventions carried out with elderly people, in which they feel part of and are responsible for their performance, show interaction and motivation for physical exercise, helping them to have a healthier and more quality life.
