Publication number: 20130131757Abstract: A functional electrical stimulation system for moving at least a portion of a body of a subject, e.g., legs. Such a system includes: a stimulator that can provide a plurality of sets of functional electrical stimulation to the legs, one or more transducers that outputs signals representative of the movement made by the legs in response to the functional electrical stimulation provided thereto, and a controller. The controller compares the output signals of the transducers resulting from the provision of two or more substantially equivalent sets of electrical stimulation to the legs and provide an output indicative of variation in the movement. The controller also, e.g., can compare the level of electrical stimulation output by the stimulator to achieve an equivalent movement of the legs so as to recognize an increase in such stimulation, where an increase can be indicative of fatigue in the leg muscles.Type: ApplicationFiled: October 31, 2012Publication date: May 23, 2013Inventors: Michael Robert Duncan, Simon Geoffrey Parker

Publication number: 20100069796Abstract: A functional electrical stimulation system (30) for moving at least a portion of a body of a subject (12), such as their legs (13, 13a). The system is adapted to monitor its performance and/or the outcome of the provision of stimulation to the subject (12) and assess whether the body portion is showing evidence of fatigue. The system (30) comprises a stimulator (35) that can provide a plurality of sets of functional electrical stimulation to the legs, one or more transducers (60, 61) that outputs signals representative of the movement made by the legs in response to the functional electrical stimulation provided thereto, and a control means (32). The control means (32) receives and processes the signals output by the transducers (60, 61) and includes a comparator adapted to compare the output signals of the transducers resulting from the provision of two or more substantially equivalent sets of electrical stimulation to the legs and provide an output indicative of variation in the movement.Type: ApplicationFiled: May 12, 2009Publication date: March 18, 2010Applicant: Neopraxis Pty Ltd.Inventors: Michael Robert Duncan, Simon Geoffrey Parker

Patent number: 7497806Abstract: An exercise system (10) for exercising at least one limb, such as the legs, of a subject with spinal cord injury or deficiency. The system (10) comprises an exercise bicycle (20) having a crank (17) and pedals (16) to which the feet of the subject can be mounted, and a functional electrical stimulation (FES) system (30). The FES system (30) stimulates the muscles of the legs and includes a transducer (51) mountable to at least one of the legs of the subject (12) that outputs signals representative of the position and/or movement of the leg when performing the exercise. The FES system (30) further includes a control means that receives and processes the signals output by the transducer (51) and outputs control signals to a stimulator (35) that through electrodes (53) provides electrical stimulation to the legs of the subject (12) so as to cause the legs to drive the crank (17) of the bicycle (20).Type: GrantFiled: August 13, 2001Date of Patent: March 3, 2009Assignee: Neopraxis Pty Ltd.Inventors: Michael Robert Duncan, Simon Geoffrey Parker, Branka Curcic

Publication number: 20090030482Abstract: A functional electrical stimulation system for controlling the movement of a portion of a body of a subject, such as the subject's legs. The system comprises a sensor that in one arrangement is mountable to a portion of the subjects' body other than the legs, for example the torso. In another arrangement, the sensor can be mountable to a walking aid, such as a crutch. The sensor outputs signals representative of the position and/or movement of the torso or walking aid. The system also comprises a control means that receives and processes the signals output by the sensor and outputs control signals to a stimulator adapted to provide electrical stimulation to the legs via electrodes in response to the position and/or movement of the torso or walking aid as determined by the sensor.Type: ApplicationFiled: January 23, 2008Publication date: January 29, 2009Inventors: Andrew Barriskill, Michael Robert Duncan, Simon Geoffrey Parker

Patent number: 7346396Abstract: A functional electrical stimulation system (30) for controlling the movement of a portion of a body of a subject (12), such as the subject's legs. The system (30) comprises a sensor (60) that in one arrangement is mountable to a portion of the subjects' body other than the legs, for example the torso (14). In another arrangement, the sensor (60) can be mountable to a walking aid, such as a crutch (20). The sensor (60) outputs signals representative of the position and/or movement of the torso (14) or walking aid (20). The system (30) also comprises a control means (32) that receives and processes the signals output by the sensor (60) and outputs control signals to a stimulator (35) adapted to provide electrical stimulation to the legs via electrodes (53) in response to the position and/or movement of the torso (14) or walking aid (20) as determined by the sensor (60).Type: GrantFiled: August 14, 2001Date of Patent: March 18, 2008Assignee: Neopraxis Pty LtdInventors: Andrew Barriskill, Michael Robert Duncan, Simon Geoffrey Parker
