Integrating augmented reality (AR) games into gait training programs could increase motivation and engagement in rehabilitation sessions. Does such AR game with visual feedback help to achieve or exceed target walking speed without increasing variability in walking speed? Is there an effect of the different feedback modalities? 15 participants walked on 30 m with 5 mini-games with different feedback modalities and a control scene without feedback. Participants had to walk at target walking speed (WS), recorded previously during calibration. The mean and standard deviation of WS during each condition were compared after ANOVA and Dunnett correction. Participants' opinions on the game and device were also collected. Mini-games did not cause any disturbance in the mean WS (p>0.05 for all mini-games vs. Control). The mini-games MG4 and MG5 resulted in high variability in WS. Participants reported high satisfaction with the game session (5/5,IQR 1). Participants judged the game effective in helping them reach the target speed (4/5,IQR 1). Specific recommendations include knowledge of results feedback, body-locked content, and clarifying game objectives. Feedback modalities influenced gait speed and variability. These results encouraged further development and evaluation of AR for gait training with careful consideration of the feedback modalities presented.
