Who could benefit from this research

Could help

Adults age 21 and older, especially those with balance complaints or concern about age-related balance decline, are the ideal candidates.

Less likely to help

People under 21 or those whose dizziness or falls are clearly due to non-vestibular causes (for example, purely neurological or orthopedic problems) are unlikely to benefit directly from participation.

What this research studies

You would come to James Madison University for noninvasive recordings of tiny electrical responses from neck and eye muscles called cVEMPs and oVEMPs while the researchers use gentle vestibular stimulation. The team will use new stimulation and recording methods designed to reveal nonlinear features of these reflexes that haven't been measured in humans before. They will compare results across younger, middle-aged, and older adults and relate the recordings to simple balance tests. The hope is to link specific signal patterns with better or worse balance function.

Why it matters

Potential benefit: If successful, this work could lead to better diagnosis and rehabilitation approaches for age-related balance problems by revealing new biomarkers of vestibular function.

How similar studies have gone: Previous studies have measured VEMPs in humans, but using these novel methods to detect nonlinear features in human vestibular reflexes is largely new and untested.
