Rhythms in Motion: A Biofeedback-Driven Vibrotactile Wearable for Gait Entrainment Rooted in Polyrhythmic Analysis of Afro-Diasporic Music

Abstract

Studies have demonstrated that synchronized auditory and tactile cues can support motor coordination through neural entrainment.[1] Emerging research suggests that rhythm-specific entrainment influences distinct aspects of gait such as stride symmetry, cadence, and joint coordination. [2] This thesis introduces a culturally grounded, rhythm-driven therapeutic device that leverages vibrotactile rhythmic stimulation for gait modulation and neurorehabilitation. While vibrotactile cueing and rhythmic auditory stimulation have been utilized for gait training purposes, these studies rely on binary and ternary rhythmic patterns. [3], [4] There are no studies that make polyrhythmic analysis the basis of the rhythmic framework utilized to deliver these therapeutic modalities. This thesis makes two key contributions. First, it introduces a novel method for modeling and applying complex polyrhythmic musical structures—drawn from Afro-diasporic music—that diverge from conventional binary and ternary rhythmic patterns typically used in existing interventions. Second, the system integrates real-time gait adaptation through embedded force sensitive resistors, enabling personalized rhythmic synchronization. By integrating polyrhythmic analysis, real-time gait adaptation, CAD-informed wearable design, and multisensory feedback, this work establishes a novel framework for personalized, culturally resonant neurorehabilitation strategies— with potential applications for individuals with neurodegenerative or motor disorders.
