Association between physical performance and autonomic nervous system in elderly fallers

Falls among older adults have become a global concern. Autonomic nervous system (ANS) function, which is implicated, can be noninvasively evaluated with heart rate variability (HRV) and blood pressure variability (BPV). The present study evaluated relationship between physical activity, physical per...
