Objective:To explore the effects of rhythmic auditory stimulation(RAS)on gait and balance abilities in patients with stroke with ataxia.Methods:60 patients with stroke ataxia were prospectively studied and divided into control(n=30)and RAS group(n=30)according to different treatment methods.The control group received conventional rehabilitation therapy and gait training accompanied by a metronome.The patients in the RAS group received conventional rehabilitation therapy and gait training accompanied by a music therapist.Both groups received continuous treatment for 4 weeks.Ataxia[International Cooperative Ataxia Rating Scale(IC-ARS)score],gait ability[Timed Upward Walking Test(TUGT)score],balance ability[Berg Balance Scale(BBS)score],gait pa-rameters of the two-dimensional gait analysis system(pace,stride,and stride),and pressure center(COP)parameters of the balance function testing system(COP swing length and COP swing area when opening and closing eyes)were compared between the two groups.Results:After treatment,the degree of change of ICARS,TUGT and BBS in the RAS group was greater than that in the control group(P<0.05).The degree of change in speed,stride length and stride length was greater in the RAS group than in the control group(P<0.05).After treatment,the degree of change in the RAS group was greater than that of the control group in terms of the COP swing length at eye opening,the COP swing area at eye opening,the COP swing length at eye closing,and the COP swing area at eye closing(P<0.05).Conclusion:The use of RAS combined with gait training can effectively improve ataxia symptoms in patients with stroke ataxia,improve gait parameters such as stride speed,stride length and stride length,enhance balance ability and reduce the amplitude of center of gravity sway,which has significant advantages in improving patients'gait and balance.
