Filter by:Pilot testing and development of an immersive virtual reality system for spatial navigation training in mild cognitive impairment syndrome.
The proposed study aims to investigate the use of a driving simulator in a virtual reality (VR) environment to improve the cognition state and spatial navigation of individuals with mild/moderate memory impairment. All volunteers will be assessed by the Montreal Cognitive Assessment (MoCA),Montgomery-Asberg Depression Scale (MADRS) and Morris Water orientation tests for baseline assessment after they sign the consent form and are enrolled into the study. Participants will also be scheduled for post-intervention assessments (MADRS, Morris Water Orientation and a simple questionnaire on how they evaluate the experiment). Participants of the study will play the driving simulator daily (5 days/week) for 15-20 minutes/day over a period of 2 consecutive weeks. Participants' daily performance data are recorded and uploaded on the secure server of the Priciple Investigator (PI). Simulator Sickness Questionnaire (SSQ) test will also be run after the first session of the experiment and at the end of the training period.
Motor control includes postural control and voluntary movement. For an optimal motor control it is necessary that brain integrates vestibular, visual and somatosensorial inputs properly, in a nonlinear way. Vestibular system, as an afferent organ, encodes head position in relation to gravity and changes in its linear and angular acceleration. As vestibular central system, it plays an essential role in motor control and in orientation and spatial memory as well. When a peripheral vestibular lesion occurs, elaboration, interpretation and processing of inputs are deficient and therefore motor control is altered to a greater or lesser degree. As process progress in time, there is a natural neuroplasticity that facilitates recovery or compensate vestibular function, although sometimes this process is incomplete and requires vestibular reeducation This study aims to assess changes in balance control, orientation and handicap perception in one case group with symptomatic unilateral peripheral vestibular dysfunction, before and after a rehabilitation programme (RV). To compare values obtained at the beginning and at the end of RV to those achieved by control group. Finally, this research aims to analyse evolution of spatial orientation quality in symptomatic and non symptomatic participants.
