It is important to understand how rhythm and music affect movements of individuals with mild-to-moderate cognitive impairment (MCI) as music choice may provide an opportunity to enhance interactions through movement performance and behaviour. Current research has explored the potential therapeutic effects of personalized music on anxiety, emotion, and memory in this target population. However, it is not clear how moving to pre-recorded music may yield benefits in movement performance and behaviour to improve the lives of persons with mild-to-moderate cognitive impairment. Therefore, the present case series study investigated if and how movement performance and anxiety changed when individuals with mild-to-moderate cognitive impairment (N=3) moved to self-chosen versus researcher chosen music when performing a movement-based task on a tablet computer compared to age and sex matched control participants (N=13). There were two sessions, one week apart, including a familiarization and an experimental session. The pre-recorded music was selected from Apple Music with self-chosen music being selected by the participant/caregiver and researcher chosen music selected by the principal investigator. The researcher chose music was within 5 beats per minute of the self-chosen music song and within a genre they enjoy. Participants performed the same movement task in each music condition, in a counter-balanced order. The results of the study indicated that music choice may have not been a factor when it came to response time, variable error, and anxiety for both the MCI and control participants. Based on the Likert enjoyment levels and the lack of any difference between self and researcher chosen music conditions, music enjoyment appears to play a larger role than autonomy to improve performance. This finding contributes to our understanding of how music enjoyment may enhance interactions through improvements in movement and anxiety in persons with cognitive impairment. Future research should seek to understand the role music choice and enjoyment play in single and whole-body movements and how rhythm and entrainment may factor into movement performance.
