Application for GRAIL system that provides multimodal analysis of gait training in a virtual reality environment

The package contains the application for the GRAIL system that provides multimodal analysis of gait training in a virtual reality environment. was implemented by adding new functionalities in the Forest Road application, which was already included in the gait suite package provided by Motek, as proof of concept. In this application, gait pattern (kinetic and kinematic parameters) are detected during the walking along a road in a wooded VR environment. The application detects in real-time the gait initial contact by analysing the ground reaction force values. Once the IC (IC) is detected, a signal is sent to the Phidget (1018_2 Phidget I/O board (Phidgets Inc)), which in turns triggers the EEG system (ANT Neuro). The trigger is the same for the left and right ICs and the identification of the left and right steps is possible off-line by analysing the EMG signal acquired on both legs. 

Another LUA Script module automatically changes the VR environment using the VR wooded setting for the walking sessions, and a setting with a white cross on a grey background as baseline condition during stand phases (treadmill speed = 0 m/s).

To use this application in your GRAIL system, download it and import as package. Then save as project.
