[Purpose] The aim of this study was to explore the effects of different frequencies of
rhythmic auditory cueing (RAC) on stride length, cadence, and gait speed in healthy young
females. The findings of this study might be used as clinical guidance of physical therapy
for choosing the suitable frequency of RAC. [Subjects] Thirteen healthy young females were
recruited in this study. [Methods] Ten meters walking tests were measured in all subjects
under 4 conditions with each repeated 3 times and a 3-min seated rest period between
repetitions. Subjects first walked as usual and then were asked to listen carefully to the
rhythm of a metronome and walk with 3 kinds of RAC (90%, 100%, and 110% of the mean
cadence). The three frequencies (90%, 100%, and 110%) of RAC were randomly assigned. Gait
speed, stride length, and cadence were calculated, and a statistical analysis was
performed using the SPSS (version 17.0) computer package. [Results] The gait speed and
cadence of 90% RAC walking showed significant decreases compared with normal walking and
100% and 110% RAC walking. The stride length, cadence, and gait speed of 110% RAC walking
showed significant increases compared with normal walking and 90% and 100% RAC walking.
[Conclusion] Our results showed that 110% RAC was the best of the 3 cueing frequencies for
improvement of stride length, cadence, and gait speed in healthy young females.
