The purpose of this study was to determine the difference in spatiotemporal gait measures induced by stepping to the beat of a metronome and to music cues of various frequencies in individuals with Parkinson's disease. Twenty-one participants with Parkinson's disease were instructed to time their steps to a metronome and music cues (at 85%, 100%, and 115% of overground cadence). The authors calculated cadence, cadence accuracy, and step length during each cue condition and an uncued control condition. The music and metronome cues produced comparable results in cadence manipulation, with reduced cadence accuracy noted at slower intended frequencies. Nevertheless, the induced cadence elicited a concomitant alteration in step length. The music and metronome cues produced comparable changes to gait, but suggest that temporal control is more limited at slower frequencies, presumably by the challenge of increasing the step length.
本研究旨在确定帕金森病患者在跟随节拍器和不同频率音乐提示进行踏步行走时时空步态测量的差异。21 名帕金森病患者被要求根据节拍器和音乐提示（85%、100%和 115%的地面步频）进行踏步行走。作者在每个提示条件和无提示控制条件下计算了步频、步频准确性和步长。音乐和节拍器提示在步频控制方面产生了类似的效果，在较慢的预期频率下，步频准确性降低。然而，诱导的步频引起了步长的相应变化。音乐和节拍器提示对步态产生了类似的影响，但提示在较慢的频率下，时间控制可能更有限，这可能是由于增加步长的挑战所致。
