Background: In recent years, the interest in user experience (UX) evaluation methods for assessing technology solutions, especially in health systems for children with special needs like cognitive disabilities, has increased.

Objective: Conduct a systematic mapping study to provide an overview in the field of UX evaluations in rehabilitation video games for children.

Methods: The definition of research questions, the search for primary studies and the extraction of those studies by inclusion and exclusion criteria lead to the mapping of primary papers according to a classification scheme.

Results: Main findings from this study include the detection of the target population of the selected studies, the recognition of two different ways of evaluating UX: (i) user evaluation and (ii) system evaluation, and UX measurements and devices used.

Conclusions: This systematic mapping specifies the research gaps identified for future research works in the area.
