Aussie current is an alternate current that realizes transcutaneous neuromuscular stimulation using medium frequency (4000Hz or 4 Khz) modulated in bursts, with short duration pulses; offering then a minor sensorial discomfort during therapy.
The therapy set to 1Khz with 2 ms of duration is used for muscular torque gain treatment, prevention or atrophy delay due to disuse, motor re-education, maintenance or increase of amplitude from articular movement. The bursts set to 4Khz with 4ms of duration used in the treatments for symptomatic relief of: intractable chronic pain, post traumatic acute pain, postoperative acute pain and increasing local blood flow.
The Russian current is defined as an alternate current of medium frequency (2.5 kHz), which provides a greater depth range, due to its lower resistance, thus contributing to a greater recruitment of motor units without significant discomfort to the patient. Their bursts have rectangular or sinusoidal shapes. It is an excitomotor current that uses surface electrodes for its application. The mechanism of action is the depolarization of the lower motor neuron, generating muscular contraction in the muscles that present their full motor innervation. It is used in therapies whose objectives are: prevention or delay of atrophy due to disuse, motor re-education, increase of muscular torque, maintenance or increase in range of motion, relaxation of muscle spasms, increasing local blood flow
The Functional Electrical Stimulation (FES / EMS) is a low frequency electrical current (approximately 1 to 100Hz), which has the following characteristics: alternate, depolarized, with symmetrical pulses.
This electrical stimulation generates an evoked potential of action that will act at the motor level, in a bidirectional way, leading to a depolarization of the motor neuron. This potential of action passes through the neuromuscular junction, reaching the motor neuron; as a result, the plastic membrane generates an action that will spread through the T tubules, thereby causing the release of calcium from the endoplasmic reticulum. This will then stimulate muscular contraction, by means of synchronous stimulation of the motor units. This synchronism leads to an efficient muscular contraction.
FES / SEM is used in rehabilitation for the purpose of preventing or delaying atrophy due to disuse, motor re-education, increasing muscular torque, maintenance or increase of joint movement amplitude, relaxing muscle spasms and increasing local blood flow.
The Transcutaneous Electrical Stimulation (TENS) is a low-frequency current, very common in rehabilitation for the purpose of analgesia.
A physiology of the action of TENS is explained by “floodgate theory”, where the transcutaneous electrical stimulus, activates the larger caliber mechanoreceptor fibers that send signals in the posterior horn of the spinal cord before smaller caliber fibers. Occurs then a depolarization of the gelatinous substance and a modulation of the stimulus in the spinal cord, which causes inhibition of the nocioreceptive stimulus. With the faster arrival of the proprioceptive stimulus in the posterior horn of the spinal cord, will occur activation of interneurons besides the release of opiate substances, such as: endorphins, dynorphins, enkephalins, noradrenaline and serotonin; these substances, acting as inhibitory neurotransmitters.
This way, TENS therapy is used in the symptomatic treatment of intractable chronic pain, relief of postoperative acute pain and increasing local blood flow
We have two Interferential currents, both of them are medium frequency sinusoidal that alternate between then, being modulated by amplitude. Its application can be carried out in bipolar (2 poles) or tetrapolar (4 poles, where at the intersection point occurs an interference); therefore, deeper tissues are reached without causing major discomfort.
It is a current widely used for the treatment of acute and chronic pains in different pathologies, such as: low back pain, osteoarthritis of the knee and others, this analgesic effect being explained by the “floodgate theory”. In addition, the literature points to the use of Interferential Current for urinary incontinence, intestinal constipation and increasing local blood flow.
Microcurrent therapy has an electric current provided by one millionth of an ampere, literally, because this is believed to be the body’s own natural current strength. This therefore restores the body’s own natural current (Mercola & Kirsch, 1995).
Microcurrent therapy comes with two self-adherent active electrode patches linked by a cable. The efficacy of Microcurrent therapy in the management of musculoskeletal pain and enhancement of wound healing has been reported.
It works on a cellular level to stimulate the healing process. It is based upon the theory that the body’s electrical balance is disrupted when one is injured, so that the natural electrical current of the body changes its course. Microcurrent stimulation restores this balance (Kirsch, 2001).
In fact, Microcurrent therapy can relieve pain, stimulate wound healing, stimulate the regeneration of injured tissue, provide relief to myofascial trigger points, increase.
Using Microcurrent therapy, ATP production increases by 500%. ATP is the primary molecule that our bodies use to produce energy and you can fiund in every cell of the body. In fact, it has been found that ATP production increased fivefold after microcurrent therapy was administered. As stated previously, protein synthesis also increased, and so did amino acid transport (Mercola & Kirsch, 1995).
In addition, Microcurrent therapy can be used at specific frequencies for a variety of tissues and conditions. This can often soften tissue and decrease pain, which provides long-lasting pain relief that may even be permanent. This has some promising benefits that may be applicable to current chronic pain conditions as well (Neumann, 1993).
Iontophoresis or ionization, also called ion transfer, is the penetration of substances via transdermal (skin) in a conservative manner, using a polarized current that drives the ionized substance by unidirectional electrical flow. The success of ion transfer is on the basic physical principle, which confirms that similar poles repel and opposite poles attract each other.
The philosophy of iontophoresis is similar to sonophoresis, although, in this case, the active principle (pharmacology) incorporated to the gel (donating solution) must have polarity defined, it means, must be ionized. The drug is propelled by electro- repulsion mechanism, positive or negative equivalent drugs are liberated, as long as they are placed under the electrode which presents the same electric charge.
It is important to highlight that the pharmacology applied in this way have superficial and in loco action and must have essential characteristics such as hydro solubility, being positively or negatively charged and be of a relatively small molecular size (Oliveira et al., 2005; Cameron, 2009).
Like with sonophoresis, iontophoresis has potential routes of skin permeation, the sweet glands being the main way, while the porous follicle, the sebaceous glands and the corneous extract contribute relatively to the ionic penetration, since they have elevated relative electrical impedance (Oliveira et al., 2005).
A polarized electric current of constant amplitude (0.1 a 1 mA/cm2) is used to increase in a controlled way the transdermal transferring of the drug and in any type of equipment the electrode which will transfer the drug is called active and the other electrode which completes the electric circuit is called dispersive (Oliveira et al., 2005; Cameron, 2009).
The high volt pulsed current (HVPC) is a current with twin pulses of high amplitude (high voltage) and short duration. The waveform is monophasic (the current flows in a single direction). The high volt causes a decrease in skin resistance making the current comfortable and tolerable. The system generally have a pulse duration that can vary from 5 to 200 µs (microseconds), a high peak amplitude (100 V to> 500 V) and frequencies of 1–250 Hz, allowing a relatively pleasant stimulation, capable of reaching the sensory, motor nerve fibers and also those responsible for conducting nociceptive impulses. Although HVPC is a single-phase current, the risks inherent in its use are minimized by the fact that the average amplitude of the direct current is very low, reaching values that can vary from 1.2 to 1.5 mA and a load that varies between 12 to 14 µC. Both, the average amplitude of the direct current and the load values, maintain a relationship with the large pulse intervals, which represent 99% of each second. HVPC produces a strong electromagnetic force that produces a “galvanotaxis effect” that induces the migration of polarized cells to the cathode or anode. The migration of neutrophils, macrophages, lymphocytes and platelets is believed to stimulate the “inflammatory phase” of the tissue healing response. Subsequent migration of fibroblasts to the wound site increases the synthesis of new tissue during the “proliferative phase” of the healing response. The migration of epidermal cells and keratinocytes is beneficial during the “remodeling and final maturation phase” of the healing response
