Wobble board-based Exergaming of different intensities provides a unique approach to enhance different cognitive and balance parameters . This study aims to determine that which of the cognitive and balance components are greatly affected by wobble board exergaming of different intensities in individuals with mild cognitive impairment (MCI).In this study ninety-seven MCI participants (MoCA 18-24, aged 50-75 years) were randomly assigned into mild, moderate, high intensity novel wobble board based exergaming, and control. All groups received 24 sessions (40 minutes/session, 3 times/week). Different cognitive components including visuospatial, naming, memory, attention, language, abstraction, orientation and global cognition and serum BDNF, while anticipatory postural control, reactive postural control sensory orientation, dynamic gait and miniBesTest (MBT) were assessed at baseline, after 4th, and 8th week. Mixed-model ANCOVA with baseline values as covariates analyzed group x time interaction effects. Post-hoc analyses analyzed the differences between complexity levels and the control group, and repeated measures ANOVA assessed within-group changes.There were significant time and group interaction for BDNF p=0.017, visuospatial p<0.001, attention p=0.045, abstraction p=0.043, global cognition p=0.025, anticipatory postural control, sensory orientation, dynamic gait, MBT (p<0.001). Post-hoc analysis at different intensities demonstrated a significant difference between different intensity groups with the control group for visuospatial, attention, anticipatory postural control, reactive postural control sensory orientation, dynamic gait and miniBesTest (p<0.01). It is concluded that wobble board exergaming of high intensity influences visuospatial, attention, abstraction, global cognition, anticipatory postural control, sensory orientation, dynamic gait abilities to a greater extent se compare to other groups.
