Galvanic StimulationHigh Voltage Pulsed Galvanic Stimulation
stimulation is most useful in acute injuries associated with major tissue trauma
with bleeding or swelling. In contrast to TENS and IFC units, which apply alternating
current, galvanic stimulators apply direct current.
Direct current creates an electrical field over the treated area that, theoretically, changes blood flow. The positive pad behaves like ice, causing reduced circulation to the area under the pad and reduction in swelling. The negative pad behaves like heat, causing increased circulation, reportedly speeding healing. The Galvanic Stimulator (direct current) is the best modality for iontophoresis treatments.
High-voltage pulsed galvanic stimulation (HVPGS) is gaining widespread use for wound healing, edema reduction and pain relief Carpal Tunnel Syndrome and Diabetic Foot are two major areas of use. Devices in this class are characterized by a unique twin- peak monophasic waveform with very short pulse duration (microseconds) and a therapeutic voltage greater than 100 volts. The combination of very short pulse duration and high peak current, yet low total current per second (Microcurrent) allows relatively comfortable stimulation. Furthermore, this combination provides an efficient means of exciting sensory, motor and pain-conducting nerve fibers. Perceptual discrimination of those responses is relatively easy to achieve and thus its clinical versatility. Back Ground Skin offers a great amount of resistance to the flow of electrical current. When current is passed through a circuit that contains resistors, voltage drop occurs and energy is lost. This phenomenon occurs when traditional low voltage units are used in treatment A high voltage device produces a spontaneous breakdown in skin resistance and HVPGS current passes through the skin with negligible thermal and electrochemical effects. The first high voltage stimulator was developed by Bell Telephone Laboratories in 1945. By decreasing the pulse duration and increasing the voltage, the developers noted that deep tissues could be stimulated without producing tissue damage. The first published report (I 966) described its effectiveness in wound healing of animal limbs. High-Voltage Pulsed Galvanic Stimulationf
Interferential Generator, INF
Interferential current (IFC): This type of stimulation
is characterized by the crossing of two electrical medium, independent frequencies
that work together to effectively stimulate large impulse fibers. These frequencies
interfere with the transmission of pain messages at the spinal cord level. Because
of the frequency, the Interferential wave meets low impedance when crossing
the skin to enter the underlying tissue. This deep tissue penetration can be
adjusted to stimulate parasympathetic nerve fibers for increased blood flow.
Interferential Stimulation differs from TENS because it allows a deeper penetration
of the tissue with more comfort (compliance) and increased circulation.
Interferential current is essentially a deeper form of TENS. In essence, IFC modulates a high frequency (4000 Hz) carrier waveform with the same signal produced by a TENS unit. The high frequency carrier waveform penetrates the skin more deeply than a regular TENS unit, with less user discomfort for a given level of stimulation. Deep in the tissues, the carrier waveform is cancelled out, resulting in a TENS-like signal deep under the skin.
Anecdotal evidence suggests that the IFC units may be useful for patients who have not had relief from TENS.
Interferential electrical stimulation's is a unique way of effectively delivering therapeutic frequencies to tissue. Conventional TENS and Neuromuscular stimulators use discrete electrical pulses delivered at low frequencies of 2-160 Hz per second. However, Interferential stimulators use a fixed carrier frequency of 4,000 Hz per second and also a second adjustable frequency of 4,001-4,400 Hz per second. When the fixed and adjustable frequencies combine (heterodyne), they produce the desired signal frequency (Interference frequency). Interferential stimulation is concentrated at the point of intersection between the electrodes. This concentration occurs deep in the tissues as well as at the surface of the skin. Conventional TENS and Neuromuscular stimulators deliver most of the stimulation directly under the electrodes. Thus, with Interferential Stimulators, current perfuses to greater depths and over a larger volume of tissue than other forms of electrical therapy. When current is applied to the skin, capacitive skin resistance decreases as pulse frequency increases.' For example, at a frequency of 4,000 Hz (Interferential unit) capacitive skin resistance is eighty (80) times lower than with a frequency of 50 Hz (in the TENS range). Thus, Interferential current crosses the skin with greater ease and with less stimulation of cutaneous nociceptors allowing greater patient comfort during electrical stimulation. In addition, because medium-frequency (Interferential) current is tolerated better by the skin, the dosage can be increased, thus improving the ability of the Interferential current to permeate tissues and allowing easier access to deep structures. This explains why Interferential current may be most suitable for treating patients with deep pain, for promoting osteogenesis in delayed and nonunion fractures and in pseudothrosis, for stimulating deep skeletal muscle to augment the muscle pump mechanism in venous insufficiency, and for depressing the activity of certain cervical and lumbosacral sympathetic ganglia in patients with increased arterial constrictor tone.
Pre and post-orthopedic surgery, joint injury syndrome, cumulative trauma disorders, increasing circulation and pain control of various origins.
Interferential Therapy is used in the treatment of circulatory disorders, range of motion, edema and muscle spasms. Post-op patients will use the device 3 times a day for 15 minutes over a period of 14 - 30 days.
Since Interferential Therapy has been in use for many years, its effectiveness is well documented. Studies have shown that patients using Interferential Therapy after surgery develop fewer post-op complications than those relying solely on narcotics for pain relief. Interferential stimulation does not cause respiratory depression. Interferential Therapy aids in circulation, increasing the recovery time for patients. Multiple treatments at home or work will typically speed the patient's recovery and allow earlier resumption of their normal lifestyle.

Microcurrent Electrical Neuromuscular Stimulator,
The newest units use a very low voltage current, usually between 1uA and 1000uA. A microamp (uA) is 1/1000 of a milliamp (mA), so 1000 uA equals 1 mA. Most TENS devices have a milliamplitude of 1-80 mA.
Where TENS is used to hide pain, Microcurrent, because of its close proximity of our own body’s current, is thought to work on a more cellular level. It has been theorized that healthy tissue is the result of the direct flow of electrical current throughout the body. Electrical balance is disrupted when the body is injured at a particular site, causing the electrical current to change course. The use of Microcurrent over the injured site is thought to realign this flow, thus aid in tissue repair. It's been found that ATP (Adenosine Triphosphate) in the cell helps to promote protein synthesis and healing. The lack of ATP due to trauma of the tissue results in the decreased production of sodium and an increase in metabolic wastes, which is perceived as pain. The use of Microcurrent at an injured area helps to realign the body’s electrical current, increase the production of ATP, resulting in increased healing and recovery, as well as blocking the pain that is perceived.
The electrical current used in Microcurrent Therapy is so small that it is rarely felt physically, however biologically it has an effect. The water-moistened electrodes or gel used to conduct the current may seem cool when first applied.

Bioscope Strength Duration TENS
Bioscope Strength Duration TENS reduces pain by controlling each channel independently. This is a Tens Unit that operates with Burst, Normal or Modulation modes. This is a dual channel unit, which allows you to use up to four electrodes at a time (two electrodes per channel).
The SD TENS offers six settings on the mode switch.
Burst Mode - This mode provides a series of seven pulses at a fixed rate of 80Hz. Bursts occur two times per second. .
Normal Mode - This mode provides standard stimulation for TENS.
Modulation Modes - The four modulation modes are designed for the patient to obtain maximum comfort from TENS. Individual preferences can be met with these additional modes, improving patient compliance. Modulation of the TENS output parameters: width, rate and amplitude may prevent the nervous system from accommodating to the continuous mode of TENS, thus improving duration of pain relief.
A. Strength-Duration Modulation (SD): Strength-Duration Modulation consists of alternating modulated amplitude and width so that one parameter is always decreasing while the other is increasing and vice versa. The amplitude decreases 60% from the amplitude control setting and returns to that setting. The width decreases 50% from the width control setting and returns to that setting. Total cycle time is six seconds.
B. Modulated Width (MW): Pulse width decreases 48% (pulse width= 250 u sec.), 33% (pulse width= 180 u sec.) from the selected value, and then returns to the selected value. Total cycle time is six seconds.
C. Modulated Rate (MR): Pulse rate decreases 63% (pulse rate= 150 Hz), 56% (pulse rate= 100 Hz) from the selected value, and then returns to the selected value. Total time is six seconds.
D. Combination Modulation (CM): Combination modulation consists of alternating modulated width and modulated rate so that one parameter is always decreasing while the other is increasing and vice versa.
