A Theoretical Framework: Low-Frequency Rhythmic Multimodal Movement as a Potential Intervention for Neurodevelopmental Conditions

Abstract Current sensory-cognitive interventions targeting neurodevelopmental disorders are limited by poor long-term participant adherence and low cross-population generalizability. This article develops a theoretical framework arguing that low-frequency communal rhythmic folk movement—characterized by steady periodic beat, sustained vestibular input, and intrinsically motivating group ritual context—aligns with the principles of low-intensity, sustained multimodal neuromodulation. A testable mechanistic hypothesis is proposed linking the ~2–4 Hz rhythmic frequency of this class of folk movement to neural entrainment within delta and theta brainwave bands, a neural process critical for speech envelope processing (Goswami's Atypical Rhythm Risk hypothesis). This paper elaborates the underlying theoretical logic, presents a low-load modified movement protocol for future empirical testing, and proposes standardized randomized controlled trial designs for future empirical validation. Pending rigorous empirical validation, this framework offers a low-cost, sustainable, scalable intervention model for cognitive remediation and special education practice.
