The Influence of Music on Player Performance in Exergames for Parkinson’s Patients

This study investigates the impact of auditory cues on the physical performance of patients with Parkinson’s disease (PD) within the context of motion-controlled exergames. The primary objective was to determine whether music—specifically music synchronized with game interactions—could enhance movement precision and quality compared to gameplay without auditory stimulation. The research posits that integrating music into rehabilitation exergames may help mitigate common PD symptoms, such as reduced movement amplitude and freezing, by providing rhythmic external stimuli.

The study utilized a prototype exergame involving a repetitive reaching task, where 24 participants with a mean age of 70.9 were randomly assigned to three groups: one with music synchronized to game events, one with unsynchronized background music, and a control group with no music. Performance was measured through in-game scoring across three rounds of play. Data analysis revealed that participants in both music-enabled groups significantly outperformed the control group in the second round of gameplay. However, there was no statistically significant difference in performance between the synchronized and unsynchronized music groups.

The findings suggest that the presence of music, regardless of its rhythmic alignment with specific game actions, provides a performance-enhancing effect for PD patients in a digital environment. Notably, participants did not consciously synchronize their movements to the beat, suggesting that the benefits may stem from the general immersive or motivational qualities of the music rather than explicit rhythmic guidance. The authors conclude that while music is a viable tool for improving exergame outcomes, future research should examine whether explicit instructions to follow the beat could further optimize patient performance.
