Music therapy has been developing systematically from ancient to now. Starting with thousands of years ago, there was a legendary musician in the ancient Greeks, who could play music that vibrated all living things. In 1993, Rauscher et al. found that Mozart music improved the cognition of college students. Afterwards, the term ‘Mozart effect’ has been coined. Some studies suggested the ability of music in modulating neurological and cardiac functions in our bodies. Currently, music therapy was then defined as “a systemic process of intervention wherein the therapist helps the client to promote health and so develop dynamic forces of change”. Music therapy has been applied on neurological clients with epilepsy with positive impact. Epilepsy often coincides with the spastic cerebral palsy due to the developmental disorder with a certain extent of brain damage. However, studies on the music therapy on spasticity are limited. While the common spasticity managements include the use of medications such as Baclofen or Botulinum toxins injections and physical rehabilitation such as pain-control, stretching and positioning, if more options of therapy are provided, it could be glad tidings to the individual with spasticity. Mozart K.448 was chosen to be the music group in a number of studies with positive effects found on cognition, stress and epilepsy.
