The purpose of this study was to examine the Functional Ambulation Performance Score (FAP; a quantitative gait measure) in persons with Parkinson's Disease (PD) using the auditory stimulation of a metronome (ASM). Participants (n = 16; 5F/11M; range 60--84 yrs.) had a primary diagnosis of PD and were all independent ambulators. Footfall data were collected while participants walked multiple times on an electronic walkway under the following conditions: 1) PRETEST: establishing baseline cadence, 2) ASM: metronome set to baseline cadence, 3) 10ASM: metronome set to 10% FAP scores increased between PRETEST and POSTTEST. PRE/POSTTEST comparisons also indicated decreases in cycle time and double support and increases in step length and step-extremity ratio (step length/leg length). The results confirm prior findings that auditory stimulation can be used to positively influence the gait of persons with PD and suggest beneficial effects of ASM as an adjunct to dopaminergic therapy to treat gait dysfunctions in PD.
本研究的目的是使用节拍器的听觉刺激（ASM）来检查帕金森病（PD）患者的功能性步行表现评分（FAP；一种定量步态测量方法）。参与者（n = 16；5名女性/11名男性；年龄范围60 - 84岁）主要诊断为PD，且均为独立步行者。在以下条件下，参与者在电子步道上多次行走时收集脚步数据：1）预测试：建立基线步频，2）ASM：节拍器设置为基线步频，3）10ASM：节拍器设置为比基线步频快10%。预测试/后测试比较还表明，周期时间和双支撑时间减少，步长和步端比（步长/腿长）增加。结果证实了先前的研究结果，即听觉刺激可用于对PD患者的步态产生积极影响，并表明ASM作为多巴胺能治疗的辅助手段对治疗PD患者的步态功能障碍具有有益作用。
