BackgroundThrough providing on-demand visual and auditory cues while walking,augmented reality (AR) can theoretically cue spatiotemporal gait adaptations in, populations such as those with Parkinson's disease. However, given the novelty of the, technology, the type and extent of gait adaptations in response to such a cueing, system are unknown. Before such systems can be incorporated into rehabilitation, approaches, it is important to understand how people interact with the technology.Research questionsWhat are the effects of visual and auditory cues delivered, through AR on spatiotemporal walking patterns and variability in a healthy, young, population? Is there a relationship between system usability and gait variability?, methodsTwenty healthy, young participants walked in four different cueing conditions using an AR headset: No Cues (NC) (i.e., natural gait), Auditory (A), Visual (V), and Auditory + Visual (AV). Inertial measurement units recorded spatiotemporal gait data at 200 Hz, a System Usability Survey was administered afterward, and linear regression models were developed to examine whether gait variability is predictive of system usability.ResultsAll cueing conditions exhibited a significantly slower cadence compared to, NC trials. Cadence variability was significantly higher for A trials compared to V and, NC. V trials exhibited significantly decreased stride lengths compared to NC. Increased, reported system usability was significantly correlated with decreased stance phase, time variability across A trials.SignificanceOur findings support that holographic spatial-visual and auditory cues, are promising to evoke spatiotemporal gait adaptations. Results also support the, notion that the type of system and cue delivery design may impact gait outcomes.,Before an AR cueing system can be applied to a specific population in future, interventions, a more holistic approach towards finding the relationship between this, technology and its users is needed.
