Exploring the Role of Asymmetric Auditory and Tactile Stimulation on Modulating Gait Kinetics

This study explores the influence of Auditory Rhythmic Asymmetric Cueing (A-RAC), Tactile Rhythmic Asymmetric Cueing (T-RAC), and their combination (AT) on key kinetic gait parameters in gait rehabilitation: Vertical Ground Reaction Force Asymmetry (GRF), Push-off Force Asymmetry (POF), and Braking Force Asymmetry (BRK). Utilizing the Computer-Assisted Rehabilitation Environment (CAREN) with 18 participants, this research examines these interventions’ effectiveness in generating asymmetric gait. While the results during adaptation indicate that BRK was significantly affected by both A-RAC (p = 0.001) and AT (p = 0.003), only A-RAC had a significant effect on GRF (p = 0.002) during adaptation. None of the interventions significantly altered POF, suggesting its resistance to sensory cue modification. These findings provide valuable insights for enhancing gait rehabilitation strategies, particularly in addressing vertical load distribution, controlled deceleration, and overall walking safety.
