Various forms of neurological or muscular impairment due to accident or disease can jeopardize freedom of mobility of those affected. Example: foot drop - a walking (gait) abnormality in which the afflicted person cannot lift the front part of their foot. These persons typically have abnormal gait patterns to avoid tripping or falling. Evolution Devices is developing innovative assistive and augmentative technologies designed to restore mobility. Employing a muscle stimulator Evowalk is a muscle stimulator using leading edge mach ine learnng and motion tackingto treat walking impairmant and to enable remote physical therapy. The. device's stimulation timing controller is based on artificial intelligence that adapts to a wide variety of gaits (e.g. different people, terrains, speeds, and activities).
