Auditory And Visual External Cues Have Different Effects On Spatial But Similar Effects On Temporal Measures Of Gait Variability, Joao R. Vaz, Troy Rand, Jessica Fujan-Hansen, Mukul Mukherjee, Nicholas Stergiou

Journal Articles

Walking synchronized to external cues is a common practice in clinical settings. Several research studies showed that this popular gait rehabilitation tool alters gait variability. There is also recent evidence which suggests that alterations in the temporal structure of the external cues could restore gait variability at healthy levels. It is unknown, however, if such alterations produce similar effects if the cueing modalities used are different; visual or auditory. The modality could affect gait variability differentially, since there is evidence that auditory cues mostly act in the temporal domain of gait, while visual cues act in the spatial domain of …
