Electronic Assistive Technology to Support Memory Function After Traumatic Brain Injury: A Systematic Review of Efficacy and User Perspectives

Abstract

Abstract Rapid technology advances have led to diverse assistive technology (AT) options for use in memory rehabilitation after traumatic brain injury (TBI). This systematic review aimed to evaluate the efficacy of electronic AT for supporting phases of memory in daily life after TBI. A secondary aim was to examine user perspectives on the utility of AT and factors influencing uptake or use. A systematic search of PsycINFO, MEDLINE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Excerpta Medica database (Embase), Scopus, and Cochrane Library was conducted from database inception to June 13, 2022, to identify eligible studies. Methodological quality was assessed by two independent reviewers. Nineteen eligible articles involving a total of 311 participants included four randomized controlled trials (RCTs; Class I), five single-case experimental designs (Class II), and 10 pre-post group (n > 10) or single-case studies without experimental control (Class III). Three Class I studies, two Class II studies and eight Class III studies supported the efficacy of AT for supporting memory functioning. Treatment fidelity was not examined in any study. There was the most empirical support for the efficacy of AT for facilitating retrieval and execution phases of memory (i.e., supported by 6/9 studies) with external support to encode memory intentions or pre-programmed reminders. Further controlled studies are needed to determine whether outcomes vary according to individuals' level of independence with use (e.g., self-initiated vs. pre-programmed reminders) and to examine user characteristics and design features influencing uptake and effectiveness. Greater involvement of end-users with brain injury in the design and evaluation of AT features is also recommended to enhance usability and uptake in daily life.
