Research Reports - Computerized cognitive rehabilitation of attention and executive function in acquired brain injury

J Head Trauma Rehabil. 2015 Dec 24. [Epub ahead of print]

Bogdanova Y(1), Yee MK, Ho VT, Cicerone KD.

OBJECTIVE: Comprehensive review of the use of computerized treatment as a
rehabilitation tool for attention and executive function in adults (aged 18 years
or older) who suffered an acquired brain injury.
DESIGN: Systematic review of empirical research.
MAIN MEASURES: Two reviewers independently assessed articles using the
methodological quality criteria of Cicerone et al. Data extracted included sample
size, diagnosis, intervention information, treatment schedule, assessment
methods, and outcome measures.
RESULTS: A literature review (PubMed, EMBASE, Ovid, Cochrane, PsychINFO, CINAHL)
generated a total of 4931 publications. Twenty-eight studies using computerized
cognitive interventions targeting attention and executive functions were included
in this review. In 23 studies, significant improvements in attention and
executive function subsequent to training were reported; in the remaining 5,
promising trends were observed.
CONCLUSIONS: Preliminary evidence suggests improvements in cognitive function
following computerized rehabilitation for acquired brain injury populations
including traumatic brain injury and stroke. Further studies are needed to
address methodological issues (eg, small sample size, inadequate control groups)
and to inform development of guidelines and standardized protocols.
