节律性听觉刺激对帕金森病患者步态的影响

The effect of rhythmic auditory stimulation on the gait of Parkinson＇s disease patients

目的探讨节律性听觉刺激对帕金森病（PD）患者步态的影响。方法选取PD患者42例，按随机数字法分为对照组（21例）和听觉刺激组（21例），2组均采用常规抗PD药物进行治疗，听觉刺激组在此基础上增加节律性听觉刺激训练，要求患者行走时按照节拍进行行走训练，连续训练3周。2组患者均于训练前和训练3周后采用美国Motion Analysis公司研发的三维运动分析系统进行步态测试，并进行PD综合评分量表（UPDRS）第Ⅱ部分和第Ⅲ部分评分、Berg平衡量表评分（BBS）和6min步行测试（6MWD）。结果治疗3周后，听觉刺激组步长和步频分别为（49．5±3．4）cm和（88．7±8．1）步／min，与组内治疗前和对照组治疗后比较，差异均有统计学意义（P〈0．05）。治疗3周后，听觉刺激组的UPDRSⅡ评分、UPDRSⅢ评分、6MWD及BBS评分与组内治疗前和对照组治疗后比较，差异均有统计学意义（P〈0．05）。结论节律性听觉刺激训练可辅助改善PD患者的步态，促进PD患者的运动功能的恢复。

Objective To investigate the effect of rhythmic auditory stimulation on the gait of patients with Parkinson＇s disease. Methods Forty-two patients with Parkinson＇s disease were divided into an auditory stimulation group and a control group with 21 cases in each. Both groups received conventional drug treatment, but the auditory stimulation group also received rhythmic auditory stimulation training for 10 minutes, 3 times daily for 3 weeks. This involved their attempting to walk in time with a beat. The 2 groups were assessed with gait tests using a 3-dimensional motion analysis system before training and after the 3 weeks of training. Assessments using the united Parkinson＇s disease rating scale （UPDRS） , Berg＇s balance scale and the 6-minute walk test were carried out. Results The auditory stimulation group＇s average stride length and stride frequency improved significantly after 3 weeks of treatment, and were then significantly better than the control group averages. Conclusion Rhythmic auditory stimulation helps improve the gait of Parkinson＇s disease sufferers and promotes the recovery of motor function.
