It is hypothesized that misperception of a person's operational limitations during postural movement might cause falling in the elderly. The line of research is to investigate age related differences in the brain electrical activity (EEG) associated with postural movement as well as with perception of postural instability that aged and young adults use to prevent falling.

The specific hypothesis is that there are behavioral changes which relate wih a wide spectrum of brain related events responsible for signalling postural instability and initiating compensatory movements in order to avoid falls in aged adults.
