This study aimed to investigate the differences in gait outcomes of young adults with cerebral palsy (CP) following rhythmic auditory stimulation (RAS) with different types of cueing. A total of 13 ambulatory adults with CP were recruited. The participants were assigned to receive either RAS with simple chords or RAS with complex chords. Each participant received 30-min individual sessions three times per week for 4 weeks. In the simple RAS group, basic chords were used for cueing. In the complex RAS group, the diversified chords were adopted from patients’ preferred music. At pre- and posttest, spatiotemporal and kinematic parameters and the range of motion (ROM) for each joint during a gait cycle were collected. After RAS, cadence, velocity, and stride length significantly increased, but no significant group effect was found. Meanwhile, regarding kinematic parameters, a significant interaction effect between time and group was observed with the angle of plantar flexion in the preswing phase and ROM in the ankle. The complex RAS group showed increased maximal ankle plantar flexion in the preswing phase. These results demonstrated that the primary agent for gait control is rhythm, while perception of music facilitates patient engagement in walking differently depending on the level of musical elements.
