Abstract: Purpose Stroke survivors experience difficulties in performing computer-based cognitive tasks due to motor impairments that restrict the use of traditional computer input devices (e.g. mouse and keyboard). This study aimed to evaluate the feasibility of a 3D-printed switch as an alternative computer input device for computer-based cognitive tasks in stroke survivors.Methods A repeated-measures design was used in 14 stroke survivors. Participants completed Go/No-go and Stop-Signal Tasks under three conditions: a 3D-printed switch, a commercial switch, and a keyboard. The cognitive performance, usability, and satisfaction were also assessed.Results The 3D-printed and commercial switches showed significantly faster reaction times in the Go/No-go task and better response inhibition in the Stop-Signal task compared to the keyboard (p < 0.05). In addition, usability and satisfaction were significantly higher for both the 3D-printed and commercial switches than for the keyboard (p < 0.05). No significant differences in cognitive performance, usability, or satisfaction were observed between the 3D-printed and commercial switches (p > 0.05).Conclusion These findings suggest the feasibility of 3D-printed switches as cost-effective and accessible alternatives to commercial assistive devices for computer-based cognitive tasks in stroke survivors.
