Key Takeaway
Narrative review mapping mechanisms by which low-frequency sound vibration (up to 250 Hz) affects human health through hemodynamic, neurological, and musculoskeletal pathways.
Summary
This narrative review maps the landscape of mechanisms by which sound vibration affects human health, focusing on low frequency sound (up to 250 Hz) including infrasound (1-16 Hz).
Types of application covered include whole body vibration, vibroacoustics, and focal vibration applications. The review categorizes response mechanisms into hemodynamic, neurological, and musculoskeletal effects.
Methods
- Narrative review of research literature
- Categorization by mechanism type
- Focus on low frequency sound (up to 250 Hz)
- Coverage of multiple delivery methods
Key Results
- Hemodynamic effects: blood flow and circulation changes
- Neurological effects: protein kinase activation, nerve stimulation, vibratory analgesia, oscillatory coherence
- Musculoskeletal effects: muscle stretch reflex, bone cell progenitor fate, bone ossification/resorption, anabolic effects on spine and intervertebral discs
Limitations
- Field complexity requires more comparative research
- Need studies on specific frequencies and intensities
- Optimal parameters for different mechanisms unclear
- Calls for greater interdisciplinary cooperation
