Objective: To compare psychomotor function between a music student group who had music education and a non-music student group who participated in music training.
Material and Method: Consecutive sampling was used for completing questionnaires, testing reaction times (visual, auditory, and tactile system), measuring electromyography of upper trapezius muscles both sides and taking photos of the Craniovertebral (CV) angle in the sitting position. Data collection was made twice for each student group: the music students at one-hour intervals for resting and conducting nonmusic activities, the non-music students at two-day intervals, 20 minutes/session, and performed music training (by a manual of keyboard notation).
Results: The non-music students (n = 65) improved reaction times, but responded slower than the music students except for the tactile system. The music students (n = 28) showed faster reaction times and higher activities of the trapezius muscle than the non-music students at post-test. In addition, the CV angle of the non-music students was significantly improved.
Conclusion: The level of musical ability may influence the psychomotor function. Significant improvement was observed in
visual, auditory and tactile reaction time, and CV angle in the non-music students. However, upper trapezius muscle activities
between both student groups were unchanged.
