Overview
The investigators aim to study which measurements/definitions from continuous blood pressures measurements (using a Finometer) and from cerebral oxygenation measurements (using near-infrared spectroscopy (NIRS)) are associated with future fall incidents in older adults at risk of falls.
Description
Patients aged 65 years and over with a fall in the last 12 months are eligible for inclusion. After being informed about the study, all participants giving written informed consent will perform the active stand procedure (5min lying, 5 min standing). The hemodynamic measurements that will be performed during this procedure simultaneously consist of:
- Volume-clamp photoplethysmography on the finger in the digital artery (Finapres medical systems, Enschede, The Netherlands) for continuous blood pressure measurements.
- PortaLite MKII (Artinis medical systems, Elst, The Netherlands) for continuous cerebral oximetry (NIRS).
After completing the measurements, participants will receive a falls calendar and will be instructed to record falls, fall-related injuries, and fall-related healthcare use on a weekly basis for 12 months.
