The ability of performing a balance or walking task in conjunction
with a secondary cognitive or motor task, referred to as dual-task (DT) ability,
is essential in daily living. While there is some evidence that DT performance is
impaired in individuals with neurological conditions, using reliable and valid
tools to measure DT performance is essential.
This systematic review aimed to
evaluate the psychometric properties of DT balance and walking assessments in
individuals with different neurological conditions. METHODS: A systematic
literature search was conducted using PubMed, CINAHL, MEDLINE, PsycINFO, SCOPUS,
Web of Science, and Cochrane Library (last search done in April 2016). The
methodological quality was rated using the Consensus-based Standards for the
selection of health Measurement Instruments (COSMIN) checklist. RESULTS:
Twenty-three articles involving individuals with stroke, Parkinson's disease,
mild cognitive impairment, dementia, Alzheimer's disease, and multiple sclerosis
were included. Outcomes derived from the walking tasks under DT condition
generally demonstrated good reliability (correlation coefficient >/=0.75) across
different neurological disorders, but their usefulness in distinguishing fallers
from non-fallers was inconclusive. The reliability of outcomes derived from the
cognitive/motor tasks and from the dual-task effect (DTE) (i.e., DT performance
minus single-task performance) seemed to be lower but was understudied. The
reliability of static or dynamic sitting/standing balance outcomes in DT
condition was not assessed in any of the selected studies. CONCLUSIONS: The
reliability of the outcomes derived from walking tasks was good. The psychometric
properties of other DT outcomes need to be further investigated.
