This first publication in the ParViS (Parkinson Vibrating Socks) project has enabled the group led by Dr. Stojan and PD Dr. Kutz to lay the foundation for the course of the ParViS project. The current publication describes a method with which gait data and neurophysiological processes can be recorded with high temporal synchrony in the virtual reality of the GRAIL system. The synchronous measurement of spatially high-resolution combined EEG and fNIRS measurements (64 EEG channels and 43 fNIRS channels) with kinematic and kinetic data is achieved by using the Labstreaming Layer environment, a photodiode and a Raspberry Pi.
