Variability in gait speed is influenced by age and health status. However, no study has investigated the effects of different instructions on gait speed.
This study investigated how walking prompts contributed to variability in gait speed.
Participants walked on a pressurized walkway. Gait speed variability was assessed using multilevel modeling.
61% of the variance in gait speed was due to instruction, while 14% was due to individual differences.
Reference values for gait speed across a number of prompts will be highly useful for assessing gait performance in young adults. Further, the instruction given produces a large amount of variability in selected walking speed. This finding urges researchers to maintain consistency when delivering walking instructions.
步速的变化受年龄和健康状况的影响。然而，尚无研究调查不同指令对步速的影响。
本研究旨在探讨行走提示对步速变化的影响。
参与者在压力步道上行走。使用多层次模型评估步速变异性。
步速的 61%差异归因于指令，14%归因于个体差异。
在多个提示下，步速的参考值将非常有助于评估年轻人的步态表现。此外，所给的指令会在所选步行速度上产生大量的变异性。这一发现促使研究人员在提供行走指令时保持一致性。
