Neuromechanical Gait Assist Laboratory

The Neuromechanical Gait Assist Laboratory (NmGAL), directed by APT Investigator Rudi Kobetic, occupies approximately 450 square feet at LSCVAMC and is dedicated to the development and bench testing of neuromechanical systems, namely hybrid neuroprostheses that combine lower extremity orthoses with electrical stimulation technology, in order to restore and assist gait for people with paraplegia. The laboratory has a custom Matlab (Mathworks, Inc.) xPC Host-Target real-time control setup capable of acquiring a variety of sensor signals and controlling the hybrid neuroprosthesis for preliminary bench testing of novel control systems. There is a MicroScribe G2X 3D digitizer (RevWare) capable of acquiring the physical characteristics of 3D objects, such as orthoses, and accurately translates these objects into 3D models or vector-based data that can be utilized or modified in computer-aided design software. The NmGAL also contains a Prussa i3 MK2 3D printer (Prussa Research), as well as a workbench, electronic supplies and equipment, and hydraulic components and pumps for constructing mechanical, electronic, and/or hydraulic mechanisms as a part of designs and research for neuromechanical systems.
