Executive functioning, motor programming, and functional independence: accounting for variance, people, and time.
Assessing functional independence is an important part of making diagnostic decisions and treatment recommendations but is often complicated by the limitations of self-report and behavioral measures. Alternatively, it may be worthwhile to investigate neurocognitive correlates of incipient functional declines including using tests of executive functioning (EF) and motor programming (MP). The current study examined an electronic MP task and pitted it against other assessment instruments to evaluate its relative utility in assessing both EF and functional independence. Participants were 72 community-dwelling older adults. Results of this study showed that the MP task was correlated with other measures of EF, an efficient and reliable predictor of functionality, useful for identifying at-risk patients, and comparable to a longer battery in terms of sensitivity and specificity.
