The RETRAIN Trial (Phase 1)

The primary objective is to investigate in stroke patients the impact of geko™ NMES treatment, when used as standard of care for VTE prevention, on brain haemodynamics at different stimulation levels and in three different postural positions (supine, semi-supine \[45° seated\] and seated). The aim is to identify the optimal stimulation level and postural position for the maximum response (NMES versus no NMES) with regard to relative total haemoglobin concentration (i.e., the sum of relative deoxyhaemoglobin and oxyhaemoglobin concentrations) using fNIRS and EEG.
