Effects of gaze stability exercises on cognitive function, dynamic postural ability, balance confidence, and subjective health status in old people with mild cognitive impairment

The purpose of this study was to determine whether gaze stability exercises would result in improvements of cognitive function, balance ability and subjective health status in old people with and without mild cognitive impairment (MCI). Old people with MCI (n=9) and healthy old people (n=9) performed gaze stability exercises for 4 weeks. Pre and post Montreal Cognitive Assessment (MoCA) for cognitive function, Timed Up and Go test for dynamic postural ability, Activities-Specific Balance Confidence for balance confidence and subjective health status were measured in both groups. After participating in gaze stability exercises, all outcome measures were significantly improved in MCI group and normal group also improved significantly in all outcome measures with the exception of balance confidence. In addition, there were significant differences in cognitive function and balance confidence between the two groups, and more improvements in MCI group. These results provide evidence that gaze stability exercises is beneficial to improve cognitive function as well as balance ability which affected on quality of life in old people with and without MCI.
