Patent number: 12017072Abstract: A gait management apparatus applies stimulation to a user suffering from a neurological disease (such as Parkinson's Disease) gait dysfunction. Motion sensors are arranged to be worn by a patient, and electrical stimulation electrodes are on the legs for stimulation. A controller receives motion sensing signals, and processes these signals to generate stimulation signals for operation of the electrodes to stimulate limb movement upon detection of a gait abnormality. There may be a user actuator for user actuation of electrical stimulation, and the inputs may be a series of taps. The controller may provide signals to prevent occurrence of freezing of gait when it senses that a patient is walking or has an intention to walk. Also, it may apply stimulation at an intensity level which is insufficient for functional muscle stimulation but sufficiently high to trigger activation of efferent nerves.Type: GrantFiled: April 30, 2023Date of Patent: June 25, 2024Assignee: National University of Ireland, GalwayInventors: Gearóid Ó Laighin, Leo Quinlan, Dean Sweeney, Gavin Corley, James Feehilly, Patrick Browne
