Balance impairment is common in older adults with mild cognitive impairment (MCI). The ability to predict the magnitude of the body disturbance is essential to balance maintenance. The purpose of the study was to investigate the effect of the predictability of the perturbation magnitudes on anticipatory (APAs) and compensatory (CPAs) postural adjustments in older adults with MCI and healthy older adults. Fifteen individuals with MCI and fourteen age-matched control participants stood on the force platform and received the pendulum perturbations of small or large magnitudes applied to their upper body. Electromyographic activity of eight leg and trunk muscles and displacements of the center of pressure (COP) were recorded and analyzed during the APA and CPA phases of postural control. Individuals with MCI demonstrated smaller APAs in the conditions of the perturbation of unpredictable magnitude and required more trials to optimize their postural adjustments, as compared to healthy older adults. Moreover, individuals with MCI had reduced postural stability in the conditions of unpredictable magnitude of the perturbation. The findings suggest that cognitive decline adversely affects the ability to predict the magnitude of the perturbations.
