Kinect Adventures versus physical exercise on depressive symptoms of older adults: A pilot study / Kinect Adventures versus exercício físico sobre sintomas depressivos em idosos: Um estudo piloto

Abstract Introduction: Depressive and anxiety disorders are considered the main cause of emotional suffering and decrease of quality of life among older adults. It has been suggested that the practice of physical exercise can be a treatment option for anxiety and depression. Alternative approaches such serious games show promise for reducing depression symptoms. Objective: To compare the effect of virtual reality, in the form of commercially available interactive Kinect Adventures video games, compared to a standard physical exercise program on depressive symptoms of older adults. Method: This is a pilot study, parallel group, single-blind randomized controlled pilot trial that recruited two intervention groups: Interactive Video Game Kinect Adventures (IVG, n=8) versus usual physical exercise program (PEP, n=6). The two groups completed a seven week program with a total of fourteen 60-minute sessions divided into two sessions a week. The IVG completed individual training sessions using the Microsoft Xbox Kinect Adventures games and the PEP performed a group exercise program. Depression symptoms were measured using the Geriatric Depression Scale (GDS-15). This measure was assessed pre-intervention, post intervention and at 30-day follow-up. Results: There was a significant effect of assessment without group effect or interaction between factors, in the GDS-15 (RM-ANOVA, P < 0.0001). Both groups showed improvement in the GDS-15 post intervention assessment that was maintained after 30-day follow-up (Bonferroni post hoc test, P < 0.05). Conclusion: The results of this study suggest that both Interactive Kinect Adventures video games and physical exercise provide beneficial effects on depressive symptoms of older adults.

Resumo Introdução: Os transtornos depressivos e de ansiedade são considerados a principal causa de sofrimento emocional e diminuição da qualidade de vida de idosos. Foi sugerido que a prática de exercício físico pode ser um tratamento para depressão. Abordagens alternativas, como jogos interativos, podem reduzir sintomas depressivos. Objetivo: Comparar o efeito da realidade virtual, na forma de videogames interativos Kinect Adventures disponíveis comercialmente, em comparação com um programa de exercícios físicos padrão sobre sintomas depressivos de idosos. Método: Trata-se de um estudo piloto, grupos paralelos, experimental, controlado, randomizado, cego através de dois grupos de intervenção: Interactive Video Game Kinect Adventures (IVG, n = 8) versus programa de exercício físico (PEF, n = 6). Os dois grupos completaram um programa de sete semanas com um total de 14 sessões de 60 minutos divididas em duas sessões por semana. O IVG concluiu sessões de treinamento individuais usando os jogos Microsoft Xbox Kinect Adventures e o PEF realizou um programa de exercícios em grupo. Os sintomas de depressão foram mensurados através da Escala de Depressão Geriátrica (GDS-15). Essas medidas foram avaliadas pré-intervenção, pós-intervenção e no seguimento de 30 dias. Resultados: Houve um efeito significativo da avaliação sem efeito grupo ou interação entre fatores, no GDS-15 (RM-ANOVA, P <0,0001). Ambos os grupos apresentaram melhora na avaliação pós-intervenção GDS-15, que foi mantida após 30 dias de acompanhamento (teste post hoc de Bonferroni, P <0,05). Conclusão: Os resultados deste estudo sugerem que os jogos interativos Kinect Adventures e o exercício físico proporcionam efeitos positivos nos sintomas depressivos de idosos.

Dual-task demands in various motor skills through Parkinson's disease progression

Aim: The aim of this study was to investigate the effects of adding a cognitive task on the performance of three different motor tasks with different demands, discrete skills, serial skills and continuous skills, by individuals with mild, moderate, and severe idiopathic Parkinson' disease (PD). We also investigate the effect of the cognitive task in the secondary task and the cost of the dual-task. Method: This is a cross-sectional study. Individuals with idiopathic PD were divided in three groups with respect to motor severity (mild, moderate and severe groups). Participants' performances were assessed in single and DT conditions including Sit-to-Stand test (SST), Timed Up and Go (TUG), and 10-meter Walk test (T10W). Cognitive task used was verbal fluency Results: The results show that dual task impact the performance of all primary tasks. DT negatively affects the performance of the motor tasks. And there is a different impact according the severity of the disease, severe ones are more affected than mild and moderate. Conclusion: In conclusion, adding a concurrent cognitive task negatively affected the performance of discrete, serial and continuous motor tasks, and this effect is more noticeable in severe than in mild patients. Under dual-task conditions, patients improved their cognitive task performance for gait and TUG, suggesting a prioritization of the secondary task for these tasks. There was no difference between the costs of the three tasks.Abstract Aim: The aim of this study was to investigate the effects of adding a cognitive task on the performance of three different motor tasks with different demands, discrete skills, serial skills and continuous skills, by individuals with mild, moderate, and severe idiopathic Parkinson' disease (PD).

Effects of virtual rehabilitation on cognition and quality of life of patients with Parkinson's disease / Efeitos da reabilitação virtual na cognição e qualidade de vida de pacientes com doença de Parkinson / Efectos de la rehabilitación virtual en la cognición y calidad de vida de pacientes con enfermedad de Parkinson

Abstract Introduction: Parkinson's disease causes progressive decline of motor and cognitive functions leading to a decrease in the independence and quality of life of people affected. Training through virtual reality is proving effective, as it promotes cognitive and motor stimuli, which can be beneficial for these individuals, improving their quality of life. Objective: To analyze the effects of virtual reality on the cognition and quality of life of patients with Parkinson's disease. Methods: A total of 11 individuals with a mean age of 65 (9.6) years classified in stages 1 to 3 of the Hoehn and Yahr Scale participated in this study. The subjects participated in fourteen sessions lasting one hour, twice a week for seven weeks in which they practiced four games of Kinect Adventures!. They were evaluated before, immediately after the intervention and 30 days after the intervention. Cognition was assessed using the Montreal Cognitive Scale (MoCA) and quality of life was assessed using the Parkinson's Disease Questionnaire (PDQ-39). Results: Only PDQ-39 activities from the domain of daily living demonstrated a statistically significant improvement. The MoCA scores, in general, remained the same. Conclusion: Although virtual reality training promoted improvement in PDQ-39 activities in the daily life domain, it was not effective in the other domains assessed for quality of life and cognition.

Resumo Introdução: A doença de Parkinson provoca declínio progressivo das funções motoras e cognitivas, levando a uma diminuição da independência e da qualidade de vida das pessoas acometidas. O treinamento por meio de realidade virtual tem se mostrando eficaz, pois promove estímulos cognitivos e motores, o que pode ser benéfico para estes indivíduos, melhorando sua qualidade de vida. Objetivo: Analisar os efeitos da realidade virtual na cognição e qualidade de vida de pacientes com Doença de Parkinson. Métodos: Tratou-se de uma série de casos. Participaram deste estudo onze indivíduos com média de idade de 65 (9,6) anos classificados nos estádios 1 a 3 da Escala Hoehn e Yahr. Os indivíduos participaram de quatorze sessões com duração de uma hora, duas vezes por semana durante sete semanas no qual praticaram quatro jogos do Kinect Adventures!. Eles foram avaliados antes, imediatamente após a intervenção e 30 dias após a intervenção. A cognição foi avaliada por meio da Escala Cognitiva de Montreal (MoCA) e a qualidade de vida foi avaliada por meio do Questionário de Doença de Parkinson (PDQ-39). Resultados: Somente as atividades do PDQ-39 do domínio da vida diária demonstraram melhoria estatisticamente significante. Os escores da MoCA, em geral, permaneceram os mesmos. Conclusão: Embora o treinamento da realidade virtual tenha promovido melhoria nas atividades do PDQ-39 no domínio de vida diária, não foi efetivo nos outros domínios avaliados quanto à qualidade de vida e cognição.
