Feasibility and benefits of computerized cognitive exercise to adults with chronic moderate-to-severe cognitive impairments following an acquired brain injury: A pilot study

Abstract

Primary objective: The purpose of this pilot study was to explore feasibility and effects of participation in a computerized cognitive fitness exercise program by a group of adults with chronic moderate-to-severe cognitive impairments following an acquired brain injury (ABI).

Research design: This study used a mixed methods design with a convenience sample of individuals forming two groups (+/- exercise).

Methods and procedures: Following neurocognitive and satisfaction with life pre-testing of 14 participants, seven were enrolled in a 5-month, 5-days a week computerized cognitive exercise program. Post-testing of all participants and semi-structured interviews of exercise group participants were completed.

Main outcomes and results: It was feasible for adults with chronic moderate-to-severe cognitive impairments post-ABI to participate in a computerized cognitive exercise program with ongoing external cues to initiate exercise sessions and/or to complete them as needed. Significant exercise group improvements were made on memory and verbal fluency post-tests and life satisfaction. The majority of exercise group participants reported some degree of positive impact on cognitive abilities and some on everyday functioning from program participation.

Conclusions: Adults with chronic moderate-to-severe cognitive impairments following an ABI may benefit from participation in computerized cognitive exercise programs. Further study is warranted.
