OBJECTIVES: To (1) examine and compare dual-task performance in patients with
multiple sclerosis (MS) and healthy controls (HCs) using mathematical
problem-solving questions that included an everyday competence component while
performing an upper extremity fine motor task; and
(2) examine whether
difficulties in dual-task performance are associated with problems in performing
an everyday internet task. DESIGN: Pilot study, mixed-design with both a within
and between subjects' factor. SETTING: A nonprofit rehabilitation research
institution and the community. PARTICIPANTS: Participants (N=38) included persons
with MS (n=19) and HCs (n=19) who were recruited from a nonprofit rehabilitation
research institution and from the community. MAIN
OUTCOME MEASURES: Participant were presented with 2 testing conditions: (1)
solving mathematical everyday problems or placing bolts into divots (single-task
condition); and (2) solving problems while putting bolts into divots (dual-task
condition). Additionally, participants were required to perform a test of
everyday internet competence. RESULTS: As expected, dual-task performance was
significantly worse than either of the single-task tasks (ie, number of bolts
into divots or correct answers, and time to answer the questions). Cognitive but
not motor dual-task cost was associated with worse performance in activities of
everyday internet tasks. CONCLUSIONS: Cognitive dual-task cost is significantly
associated with worse performance of everyday technology.
This was not observed
in the motor dual-task cost.
The implications of dual-task costs on everyday
activity are discussed.
