Publication number: 20250161680Abstract: An example apparatus for electro-medical stimulation includes a current generator to generate a sine wave output treatment signal, and a processor coupled to the current generator to modulate a frequency and a power of the sine wave output treatment signal over a cycle of stimulation treatment to produce periods of action potential for a stimulatory treatment phase and periods of non-action potential for a rest treatment phase. The cycle of stimulation treatment includes a first time period followed by a second time period, and during the first time period, the cycle of stimulation treatment is in a period of action potential for the stimulatory treatment phase, and during the second time period, the cycle of stimulation treatment is in a period of non-action potential for the rest treatment phase.Type: ApplicationFiled: October 11, 2024Publication date: May 22, 2025Inventors: Randy Alan Murphy, William J. Carroll, Sydney J. Newkirk

Patent number: 10716939Abstract: An example method includes sending a muscle stimulation current treatment signal to one or more electrodes. The muscle stimulation current treatment signal alternates between on-off states. The method further includes sending, while the muscle stimulation current treatment signal is off, an interferential current treatment signal to the one or more electrodes.Type: GrantFiled: March 17, 2017Date of Patent: July 21, 2020Assignee: International Rehabilitative Sciences, Inc.Inventors: Randy Alan Murphy, William J. Carroll, Richard M. Terrell

Patent number: 7747332Abstract: An electrical stimulation device is combined with a biologic to increase osteogenesis (i.e., bone healing or bone formation). The electrical stimulation is osteoblastic in that it produces new bone cells and or increases the activity of the existing cells, either osteoblasts or osteocytes. The preferred biologic decreases osteoclastic activity, which is the remodeling of bone usually by destroying the bone. Thus, osteogenesis is maximized by decreasing osteoclastic activity, while at the same time increasing osteoblastic activity. Osteogenesis can also be maximized by combining electrical stimulation with a BMP. Though BMPs are generally considered to increase osteoblastic activity, certain BMPs may have an additive effect to the use of electrical stimulation.Type: GrantFiled: March 7, 2003Date of Patent: June 29, 2010Inventors: Michael B. McGraw, William A. Rux, William J. Carroll, Richard M. Terrell, Randy Alan Murphy

Patent number: 6988005Abstract: A multi-functional portable electro-medical device that is capable of providing muscle stimulation and interferential current stimulation. The multi-functional portable electro-medical device includes a multitude of safety features which are designed to prevent injury to the user while at the same time to ensure that the portable power electro-medical device is easy to use. The portable electro-medical device can be programmed to impart any combination of wave therapy to the patient.Type: GrantFiled: April 29, 2002Date of Patent: January 17, 2006Assignee: International Rehabilitative Sciences, Inc.Inventors: Michael B. McGraw, William A. Rux, William J. Carroll, Richard M. Terrell, Randy Alan Murphy

Publication number: 20040015209Abstract: 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.Type: ApplicationFiled: May 17, 2002Publication date: January 22, 2004Inventors: Michael B. McGraw, William A. Rux, William J. Carroll, Richard M. Terrell, Randy Alan Murphy
