Una experiencia de ejercicio terapéutico gamificado en un paciente con síndrome Wernicke- Korsakoff

Introduction: Wernicke-Korsakoff syndrome (WKS) is a brain disorder caused by a thiamine deficiency, the most common cause being alcoholism. Physiotherapy focuses its treatment on improving balance, gait, and coordination, and cognitive aspects must be addressed. The use of immersive virtual reality (IVR) could address these aspects. Objective: To report a case of using IVR to manage the symptoms of a patient with WKS. Methodology: A 57-year-old male (WKS 1 year since diagnosis) used IVR for 16 weeks, 2 sessions/week. Physical and functional capacity, quality of life, neurocognition, and intrinsic aspects of IVR were assessed. Results: Positive trend in the physical and functional variables: grip strength (improvements of 8.33% in the dominant hand and 4% in the non-dominant hand), lower limb mobility and strength (improvements of 5.74%), functionality and dynamic balance (improvements of 14.22%), and gait and risk of falls (improvements of 18.12%). No changes in quality of life or neurocognitive tests. Discussion: In the absence of similar studies, the improvements found, while not clinically relevant, support the idea that an IVR and therapeutic exercise intervention could maintain and/or improve the health status of a person with WKS. Conclusions: IVR in a patient with WKS of alcoholic origin proved to be a feasible and safe intervention, with improvements in gait, balance, mobility, and lower limb strength. These findings pave the way for future research into this syndrome that could confirm the benefits that IVR could provide to these patients.
