Music therapy intervention programs typically include about 18 sessions of treatment. The achievement of a physical rehabilitation goal relies on the child's existing motivation and feelings towards music and their commitment to engage in meaningful, rewarding efforts.

Both techniques use systematic processes where the therapists assist the client by using musical experiences and connections that collaborate as a dynamic force of change toward rehabilitation.
