  • Patent number: 10716939
    Abstract: 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.

  • Publication number: 20140039573
    Abstract: A portable electronic neuromuscular stimulator monitors its battery and estimates battery end of life from the number of charging cycles and usage history. The stimulator can also be used with an external adapter to retrieve internally stored data regarding usage. A simplified user interface allows the user to input a level of pain both before and after treatment.

  • Patent number: 8355796
    Abstract: A load detecting circuit has a primary side and a secondary side with a secondary side patient load impedance input having a patient-side opto-isolator and a secondary side reference resistance load input having a reference-side opto-isolator coupled to the secondary side patient load impedance input. The circuit also includes at least one primary side output resistor, wherein the patient-side opto-isolator and the reference-side opto-isolator drive the at least one primary side output resistor and an integrator for operatively controlling the secondary side and conveying the patient load input and the reference load input to the primary side, where the patient load input and the reference load input are powered by a secondary side transformer winding.

  • Publication number: 20120177955
    Abstract: 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.

  • Patent number: 8060210
    Abstract: 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.

  • Patent number: 7670307
    Abstract: 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.

  • Patent number: 7228178
    Abstract: 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.

  • Patent number: 6675048
    Abstract: 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.
