Vibration detection: its function and recent advances in medical applications.

Area of Science:

• Biomedical Engineering
• Neuroscience
• Rehabilitation Medicine

Background:

• Vibrations are ubiquitous and detectable via skin mechanoreceptors, though conscious awareness is limited.
• Whole body vibration (WBV) utilizes vibrating platforms for research and therapeutic applications in humans and animals.
• While strong vibrations can be harmful, milder vibrations show potential benefits, though clinical relevance is debated.

Purpose of the Study:

• To explore the dual mode of action of WBV, encompassing both exercise (muscle) and sensory (skin) components.
• To highlight the potential of the sensory component of WBV in stimulating the brain for treating neurological disorders.
• To emphasize the need for standardized and personalized protocols in WBV research for medical applications.

Main Methods:

• Review of existing research on WBV applications.
• Analysis of the dual mechanisms of WBV: muscular and sensory.
• Identification of key variables ('Big Five') in WBV protocols: amplitude, frequency, application method, session details, and total duration.

Main Results:

• WBV acts through both a muscle-exercise component and a skin-sensory component.
• The sensory component, by stimulating the brain, shows promise for various conditions, including brain-related disorders.
• Current research is hampered by variations in WBV settings and incomplete reporting, leading to inconclusive findings.

Conclusions:

• Optimizing WBV settings, including amplitude, frequency, and duration, is essential for its medical application.
• Translational research is needed to unravel underlying mechanisms and determine optimal WBV parameters.
• Standardized and personalized WBV protocols are required to accurately assess its true medical potential and improve reproducibility.
