Publication number: 20120177955Abstract: A 9V battery has a fuse such as a 1 amp bi-metallic resettable fuse in series with the battery cells. This would prevent over-current conditions from occurring, keeping the battery from overheating and prolonging the useful life of the battery. Once the fuse is reset, the battery is once again usable.Type: ApplicationFiled: January 6, 2011Publication date: July 12, 2012Applicant: International Rehabilitative Sciences, Inc.Inventor: Erling J.

Patent number: 8060210Abstract: A method for improving mobility and/or the quality of synovial fluid of an affected articular joint, wherein the joint is associated with at least a first muscle group and at least a second muscle group each having an antagonistic relationship for effecting mobility of the joint through a range of motion when recruited by natural neural impulses. The method includes positioning at least two first electrodes proximate to the at least first muscle group, positioning at least two second electrodes proximate to the at least second muscle group, and applying motor-level electrical stimulation to the at least first and second muscle groups via the at least two first and second electrodes in a multiphasic pattern corresponding to a sequence of electromyographic outputs.Type: GrantFiled: January 18, 2008Date of Patent: November 15, 2011Assignee: International Rehabilitative Sciences, Inc.Inventor: William J.

Patent number: 7670307Abstract: The cervical traction/stretch device kit comprises a cervical traction/stretch device including an expandable bellows section which is made of non-elastic and non-stretchable material. The device further includes a shoulder section which can be fixed to or made integral with the bellows section. At least two, preferably three, interchangeable head sections are provided so that substantially all human head sizes can be supported by the device. Also provided is a head frame section which is releasably assembled with one of the head sections, the bellows section and the shoulder section to provide a cervical traction/stretch device. The bellows section, the shoulder section and the head section have aligned U-shaped openings therein adapted to receive and support a patient's neck.Type: GrantFiled: February 8, 2008Date of Patent: March 2, 2010Assignee: International Rehabilitative Sciences, Inc.Inventors: Nathan Chitwood, Susan Nickell

Patent number: 7228178Abstract: Apparatus and methods for non-invasive electrical stimulation of the brain through skin surface stimulation of the peripheral nervous system as a treatment for movement disorders. Skin surface electrodes are positioned at predetermined peripheral surface stimulation sites on the skin surface using a variety of neural imaging techniques. A pulsatile electrical current is generated at the stimulation sites through a variety of standard electrical stimulation devices. Stimulation of the peripheral surface stimulation sites translates to electrical stimulation of a specific area of the brain.Type: GrantFiled: November 21, 2003Date of Patent: June 5, 2007Assignee: International Rehabilitative Sciences, Inc.Inventors: William J. Carroll, Richard M. Terrell

Patent number: 6675048Abstract: A multi-functional portable electro-medical device provides interferential current stimulation to promote bone growth. Two electrical signals are applied to a target area, each electrical signal being formed by a set of two electrode pads. A beat frequency is created at the location the signals intersect with each other. The beat frequency is the difference between the frequencies of the two signals and has an amplitude that is additive and greater than either signal alone. The depth of the interferential signal is increased by increasing the carrier frequency of the signals. The direction of the interferential signal shifts toward the signal having the lower amplitude. The electrical stimulation is used in combination with biologics to further increase bone growth. The target area is large enough to include multiple vertebral segments.Type: GrantFiled: July 16, 2001Date of Patent: January 6, 2004Assignee: International Rehabilitative Sciences, Inc.Inventors: Michael B. McGraw, William A. Rux, William J. Carroll, Richard M. Terrell, Randy Alan Murphy
