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.

Electrical stimulation combined with a biologic to increase osteogenesis

A portable muscle stimulator with removal data storage card is disclosed in which the removable data storage card is secured within the power muscle stimulator on specially designed rail guides which prevent the removable data storage card from being inserted to the power muscle stimulator incorrectly and which ensure that the power muscle stimulator is secured in a removable fashion within the power muscle stimulator. The portable muscle stimulator include 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 muscle stimulator is easy to use.

Portable muscle stimulator with pulse width control

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.

Multi-functional portable electro-medical device

A stimulator and a method for electrical stimulation of bone to promote osteogenesis is disclosed in which surface electrodes positioned around an incision site transmit an interferential current that has a base medium frequency alternating current between 1K-20 KHz. A digital signal processor generates a sine-wave-like waveform from a pulse generator which after further processing is used to generate two circuits for use in producing the interferential current. The effective area of stimulation is controlled by placement of electrodes and electrode orientation. Amplitude modulation of electrical circuits created at the electrode placements also augments the effective area of stimulation.

Osteogenesis stimulator with digital signal processing

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.
