Evaluation of wrist and finger function in healthy children through music-based video game therapy.

The study involved only ten healthy children, so the results cannot be generalized to children with cerebral palsy or other motor impairments. The order of conditions was not randomized; the no-music condition was always played first, so improvements in the music condition might be due to practice rather than the music itself. The children performed near ceiling levels in the games, meaning the tasks were too easy to detect any potential performance benefits from music. The usability questionnaire was not formally validated or piloted before use. Data from three of the thirteen recruited participants were excluded due to technical issues, and further paired exclusions occurred during analysis due to signal artifacts. The study only measured immediate effects during a single session, providing no information on whether these benefits persist or lead to long-term motor learning.

The study was funded by The Pontificia Universidad Católica del Perú through The Annual Research Project Competition CAP-PUCP-2022. No other conflicts of interest are reported.

Do not assume this system improves functional hand use in children with disabilities. The study was conducted on healthy children who were already performing near the maximum possible score, and the fixed order of conditions means practice effects cannot be ruled out as the cause of the observed movement consistency.
