The purpose of this study was to determine if combining visual and auditory cues has a greater effect on the gait pattern of patients with Parkinson's disease (PD) than the cues applied individually. Twenty-four individuals with idiopathic PD were recruited. Patients, while off antiparkinsonian medications, were measured on a 7.62-m walkway during two trials for each of four conditions performed in random order: without cues, with a visual cue, with an auditory cue and with both cues simultaneously. The auditory cue consisted of a metronome beat 25% faster than the subject's fastest gait speed. Brightly colored parallel lines placed along the walkway at intervals equal to 40% of a subject's height served as the visual cue. Average gait speed, cadence and stride length were calculated for each condition. Gait velocity, cadence and stride length significantly improved (p<005) when cues were used. Visual and auditory cues improved gait performance in patients with PD, but they did so in different ways. Auditory cueing significantly improved cadence, but visual cueing improved stride length. The simultaneous use of auditory and visual cues did not improve gait significantly more than each cue alone.
本研究的目的是确定视觉和听觉提示相结合对帕金森病（PD）患者步态模式的影响是否大于单独应用提示的影响。招募了24名特发性PD患者。患者在停用抗帕金森药物的情况下，在一条7.62米的走道上进行测量，对四种情况中的每一种情况进行两次试验，试验顺序随机：无提示、有视觉提示、有听觉提示以及同时有两种提示。听觉提示由比受试者最快步态速度快25%的节拍器节拍组成。沿走道以等于受试者身高40%的间隔放置的颜色鲜艳的平行线用作视觉提示。计算每种情况下的平均步态速度、步频和步幅。使用提示时，步态速度、步频和步幅显著改善（p<0.05）。视觉和听觉提示改善了PD患者的步态表现，但方式不同。听觉提示显著改善了步频，而视觉提示改善了步幅。同时使用听觉和视觉提示并没有比单独使用每种提示更显著地改善步态。
