Bone Growth Stimulators
The Pulsed ElectroMagnetic Field (PEMF) bone growth stimulation delivered by Physio-Stim is a safe, nonsurgical option for long bone nonunions. Physio-Stim may be worn over a cast, orthopedic brace, or clothing without lessening its effectiveness. Physio-Stim has everything you need in one compact, lightweight unit including success rates as high as 88%1, 2, and it comes with a written guarantee of healing.

Nonoperative treatment for nonunited fractures with Physio-Stim PEMF bone growth stimulation is particularly attractive to patients and physicians when:
•Surgery presents significant risk to the patient
•The patient does not want to undergo surgery
•Multiple procedures have previously failed

Regardless of prior fracture management method or risk considerations – including advanced age, presence of infection or tobacco use, the Physio-Stim Bone Growth Stimulator has more than two decades of proven efficacy as an alternative method to secondary surgery for established long bone fracture nonunions.

Interferential Units

Interferential Therapy (IFT) is one of various types of physical therapy. It uses a mid-frequency electrical signal to treat muscular spasms and strains. The current produces a massaging effect over the affected area at periodic intervals, and this stimulates the secretion of endorphins, the body’s natural pain relievers, thus relaxing strained muscles and promoting soft-tissue healing. Its use is contraindicated if the affected area has wounds, cuts or infections.

The basic principle of IFT is to use physiological effects of low frequency (at <250 pps) electrical stimulation of nerves without the associated painful and somewhat unpleasant side effects sometimes associated with low-frequency stimulation.

It has been suggested that IFT works in a 'special way' because it is 'interferential' as opposed to 'normal' stimulation. The evidence for this special effect is lacking, and it is most likely that IFT is just another means of stimulating peripheral nerves. It is rather a generic means of stimulation. The machine can be set up to act more like a TENS-type device or a muscle stimulator by adjusting the stimulating (beat) frequency. Some patients regard it as more acceptable, as it generates less discomfort than some other forms of electrical stimulation.

IFT is used in four clinical applications, to:
Relieve pain
Stimulate muscles
Increase local blood flow
Reduce edema

Proponents make additional claims for its role in stimulating healing and repair, and for various specialised application, such as stress and incontinence. For healing and repair, there is a dearth of quality research available.

As IFT acts primarily on the excitable (nerve) tissues, the strongest effects are likely to result from such stimulation—that is, pain relief and muscle stimulation. Other effects are likely to be secondary consequences of these.

TENS Units

T.E.N.S. is an acronym for Transcutaneous Electrical Nerve Stimulation. With the development of modern medicine doctors and scientists have perfected the use of electric pulses to treat and eliminate pain. TENS units use electro frequency at about 80 to 90 MegaHertz. According to doctors and medical professionals the TENS device is the most highly effective treatments for pain relief. A TENS unit is a device that transmits small square electrical pulses to the electrodes, which transmit this electrical pulse to the underlying nerves. The fundamental components of a TENS unit are the electrodes, a highly advanced computer chip, and an electrical battery source. The small amount of electricity is transmitted through the computer component then to the electrodes, which transmits the electrical waveform to the underlying nerves. The user can personalize the pulse frequency, which is the strength of the electrical current given to the electrode. The strength of electric current is measured in megahertz. The user can also adjust how long each pulse width is. This pulsation effect gives a cycle of higher and lower electric wavelengths. This measurement between the wavelengths is measured in time by microseconds. The strength of the pulse and the width on duration of that pulse are the two main adjustments found on TENS units. Two more features that you can get on a TENS unit are settings for a burst mode and a modulation mode. A burst mode changes the time and duration of the pulse and makes a series of seven quick pulses followed by a rest. This cycle repeats itself two times every second. The modulation mode changes the time and duration of the pulse with but uses a combination of burst and the continuous features that were preset, (pulse strength and with). This setting is often used for long-term users to confuse the pain receptors in the brain so that it cannot learn to ignore these pain-relieving frequencies.

Microcurrent

Our microcurrent units provide electro muscle stimulation through the means of an electric current delivered in millionths of an ampere.
Using the Microcurrent provides little to no feeling of electrical stimulation, this is because it runs in milli-amp vs. amps.

It has the ability to:

• Relieve Chronic Pain
• Increase the rate of wound healing
• Increase protein synthesis
• Stimulate the regeneration of injured tissue
• Stimulate lymphatic flow
• Relieve myofascial trigger points

Because microcurrent flows at one millionth of an ampere it is delivered on the same scale as the current the body produces on its own in each cell, it is therefore physiologic.

Microcurrent is subsensory and cannot be felt while it is being delivered because there is not enough current to stimulate the sensory receptors.

Traditional electrotherapy units such as TENS, Interferential and Galvanic deliver current in milliamps, which a higher level of current. They can cause muscle contraction and microcurrent cannot.

Microcurrent increases Adenosine Triphosphate production by 500% (ATP). ATP is the primary molecule from which our body produces energy, and it is found in every cell of the body.

In a study done by Ngok Cheng, M.D. entitled “The Effects of Electric Current on ATP Generation, Protein Synthesis and Membrane Transport.”, it was demonstrated that ATP production increased five times with currents from 50 uA to 1000 uA. With currents exceeding 1000 uA, which is the milliamp range, ATP production leveled, and with 5000 uA ATP production was reduced slightly. Microcurrent was also shown to increase protein synthesis and amino acid transport.
