Introduction: Parkinson's disease (PD) is a complex neurodegenerative process that usually appears from the 6th decade of life and is characterized by the appearance of motor and non-motor symptoms that progress, generating functional disability and negatively impacting in quality of life. Recently, Immersive Virtual Reality (IVR) has great positive impact on health domains: as a support in psychotherapy or as a treatment of cognitive-behavioral pathologies in neurological patients.
Objective: To analyze the current published evidence in the fields of physical and functional PD rehabilitation in fully immersive environments.
Materials and methods: A literature review, covering publications registered until December 2020 in Cinahl, Scopus, Web of Science, Sport-Discus, Dialnet and Pubmed (including Medline) was carried out. The descriptors used for the search were the terms: Parkinson disease, Virtual Reality and Exercise therapy. 140 publications were identified that addressed IVR with physical rehabilitation proposes in PD. Of these, 7 contribute useful information for pooled analysis.
Results: The results support the application of IVR to improve physical and functional capacities in the population with PD. Its feasibility, usability and safety suggest potential benefits in the treatment of the prevalent symptoms of the parkinsonian patient.
Conclusions: Research of high methodological quality is lacking, reflecting and early stage of preclinical development. Randomized control studies with larger sample size and IVR protocols that confirm the results, while analyzing their impact on the physical and functional variables related to PD are needed.
Objetivo Analizar la evidencia actual publicada en el campo de la rehabilitación física y funcional de la EP en entornos completamente inmersivos.
Materiales y métodos Se realizó una revisión bibliográfica de publicaciones registradas en las bases de datos Medline, Cinahl, PubMed, Scopus, Web of Science, Sport-Discus y Dialnet hasta diciembre de 2020. Los descriptores utilizados para la búsqueda fueron: Parkinson disease, Virtual Reality y Exercise therapy. Tras la aplicación de los criterios de selección, del total de 140 artículos identificados, se seleccionaron siete.
Resultados Describen una experiencia segura, positiva y factible, aunque obtenidos, en su mayoría, tras la aplicación de una única sesión. Los resultados hallados en las variables vinculadas a las capacidades funcionales que se deben mejorar en la EP apoyan potenciales beneficios en el tratamiento de la sintomatología prevalente del paciente parkinsoniano.
Conclusiones Los pocos estudios existentes muestran resultados preliminares, por lo que se hacen necesarias más investigaciones de mayor calidad metodológica, mayor tamaño muestral, con un proceso de control aleatorizado y protocolos que confirmen los resultados, al tiempo que analicen su impacto en las variables físicas y funcionales vinculadas a la patología parkinsoniana.
