Abstract

Variability in the timing of walking patterns has a complex mathematical structure (fractality). Fractality of gait can reflect health,so practicing walking with specific temporal coordination could be helpful for various groups at high risk of falls. However, the degreeto which gait fractalitycan be‘prescribed’using differentauditory stimuli is yet to be elucidated. This study evaluated the use of several fluctuating timing imperatives on the consistency of ‘prescribing’gait complexity in healthy individuals. 14healthy young adults cuedtimingof heel contactto anfractal auditory stimuliacross four conditions(uncued, white noise, pinknoise, and red noise)administered across three sessions(session 1, session 2, and session 3), with each experimentaltrial repeated twice within each session.Fractality differed based on the walking condition while no effect of sessionwas revealed. The results of this study suggest gait fractality adapts to various fractalstimuliand thatfractalitycan beconsistentlyprescribed in a desired direction withina group of healthy young individuals.
