Study Summary

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.

Study 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:

  1. Volume-clamp photoplethysmography on the finger in the digital artery (Finapres medical systems, Enschede, The Netherlands) for continuous blood pressure measurements.

  2. 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.
