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.

这项研究的目的是确定在帕金森氏病患者中，踩到节拍器的节拍和各种频率的音乐提示所引起的时空步态测量的差异。指导21名帕金森氏病参与者按节拍器和音乐提示计时（分别为地面节奏的85％，100％和115％）。作者计算了每个提示条件和无提示控制条件下的节奏，节奏精度和步长。音乐和节拍器提示在节奏控制方面产生了可比的结果，但在较慢的预期频率上却降低了节奏精度。然而，诱发的节奏引起步长的同时改变。音乐和节拍器提示在步态上产生了可比的变化，
