Computerized Cognitive Rehabilitation of Attention and Executive Function in Acquired Brain Injury: A Systematic Review

Abstract

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.

Motion-based virtual reality cognitive training targeting executive functions in acquired brain injury community-dwelling individuals: A feasibility and initial efficacy pilot

“…Our results are consistent with recent findings from a large meta-analysis of 14 studies encompassing 575 TBI patients [11], and with a systematic review including 28 studies of computerized cognitive rehabilitation in ABI [66]. Hallock and colleagues report that despite limited studies in the field of cognitive training, cognitive training is modestly effective in improving cognitive and functional outcomes in patients with post-acute TBI.…”

Clinical Virtual Reality tools to advance the prevention, assessment, and treatment of PTSD

“…stroke, traumatic brain injury, spinal cord injury, cerebral palsy, multiple sclerosis, etc.) (Deutsch & McCoy, 2017; Howard, 2017; Klamroth-Marganska et al, 2014; Lange et al, 2012; Merians et al, 2010), and for the assessment and rehabilitation of attention, memory, spatial skills, and other cognitive functions in both clinical and unimpaired populations (Bogdanova, Yee, Ho, & Cicerone, 2016; Matheis et al, 2007; Parsons, Rizzo, Rogers, & York, 2009; Pugnetti et al, 1995; Rizzo, 1994; Rizzo et al, 2006; Valladares-Rodriguez et al, 2016). …”

A comparative clinical study of the effectiveness of computer cognitive training in patients with post-stroke cognitive impairments without dementia

“…An investigation of the neuropsychological syndromes and domains which can be restored using computer or conventional approaches, can improve routine clinical practice (Bogdanova, Yee, Ho, & Cicerone, 2016).…”
