The purpose of the case study is to understand the effects of RAS(Rhythmic Auditory Stimulation) gait training on temporospatial and kinematic changes in young adults with spastic cerebral palsy (CP). Individual RAS gait training was repeated 11 times and continued for 30 minutes per day, 3 days per week for 4 weeks. Four adults with spastic CP served as participants and all participants showed improvement in cadence and velocity, while other temporospatial parameters present differences respectively. All participants showed improvement in the range of joint movements as the evidenced of the similar pelvic anterior tilt to normal distribution from a pathological pattern. In terms of the angles of hip flexion, knee flexion and ankle dorsiflexion, three participants indicated positive outcomes close to normal distribution and one subject didn’t show any enhancement except that his hip flexion presented a similar motion to normal distribution. Besides, the ratio of stance phase to swing phase of the gait cycle of all subjects were close to 60:40 which is normal distribution. These findings support the improvement in the effect of gait performance in adults with spastic CP after considering the characteristics of each participant and the position of their affected limb. This study suggests RAS gait training should provide potential new approaches for adult patients with cerebral palsy in rehabilitation training
