In the present work, the goal is to design, develop and test a portable VR-based MVF system that monitors behavioral information about the performance of a simple motor task. The developed application runs in a stand-alone VR system and allows the researcher to select the real and virtual hands used to perform the motor task. The system was evaluated with a group of twenty healthy volunteers (12 men and 8 women) with ages between 18 and 66 years. Participants had to repetitively perform a motor task in four different experimental conditions: two mirror conditions (performing real movements with the dominant and with the non-dominant hand) and two non-mirror conditions. A significant effect of the experimental condition on embodiment score (p < 0.001), response time (p < 0.001), performance time (p < 0.001), trajectory length (p < 0.004) and trajectory maximum horizontal deviation (p < 0.001) was observed. Furthermore, a significant effect of the experimental moment (initial, middle and final parts of the training) on the performance time was observed (p < 0.001). These results show that the monitored parameters provide relevant information to evaluate the participant's task performance in different experimental conditions.enghttp://creativecommons.org/licenses/by/4.0/Mirror visual feedbackVirtual realityBehavioral measuresResponse timePerformance timeTrajectoriesAgedYoung AdultAdultHumansAdolescentHandMiddle AgedVirtual RealityMaleMovementFemaleUser-Computer InterfaceFeedback, Sensoryresearch articleAttribution 4.0 International35206464194227610.3390/ijerph190422761660-4601International Journal of Environmental Research and Public Healthopen accessInterfaz Usuario-ComputadorMovimientoFemeninoAdolescenteMasculinoRetroalimentación SensorialManoHumanosPersona de Mediana EdadAdulto JovenAncianoAdultoRealidad Virtual2-s2.0-85124596276763283500001L2015684250
