Estimating the term…
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.
A portable electro-medical device for increasing bone growth comprising a first set of electrode pads for applying a first electrical signal having a first frequency and amplitude to a target area that includes multiple vertebral segments, a second set of electrode pads for applying a second electrical signal having a second frequency and amplitude to the target area, said first and second electrical signals forming an interferential signal having a beat frequency, and further comprising a biologic applied at the target area to increase bone growth.
A portable electro-medical device for increasing bone growth comprising a signal applicator for applying an electrical signal to a target area that includes multiple vertebral segments, and a biologic applied at the target area to increase bone growth.
A method of promoting bone growth stimulation comprising applying an electrical signal to a target area that includes multiple vertebral segments, and applying a biologic to the target area.
