For the over 1 million Americans who survive severe traumatic brain injuries each year, the road to recovery is often long and challenging.
Genomic PressSep 24 2024 Disruption of the autonomic nervous system , which controls involuntary functions like heart rate , is a common yet poorly understood consequence of TBI. While heart rate variability is a widely used measure of autonomic function, the standard 5-minute recording can be cumbersome for patients with cognitive and physical impairments.
One specific HRV metric known as root mean square of successive differences proved most robust. RMSSD is thought to reflect parasympathetic activity, an important aspect of healthy autonomic function often suppressed after brain injury. Related Stories"We're excited about the potential for ultra-short HRV to enhance post-TBI care," said senior author Roger Walz, professor at Universidade Federal de Santa Catarina. "By making autonomic assessment quicker and easier, we can expand how we track recovery in the clinic and beyond. It's a simple yet powerful tool that could reshape our understanding of the autonomic impact of these injuries.
