What are Diadynamic current?
What are Diadynamic current?
Diadynamic currents are also called Bernard’s currents based on a sine wave with a frequency of 50Hz. Due to the ease of generation of this current shape, they have been known almost from the beginning of electrotherapy, and their influence on the human body has been thoroughly studied.
How many types of Diadynamic current are there?
Diadynamic currents are classified in five types and each one has different physiological and therapeutic effects.
What is Russian current in physiotherapy?
Russian currents are alternating currents (AC) at a frequency of 2.5 kHz that are burst modulated at a frequency of 50 Hz with a 50% duty cycle. The stimulus is applied for a 10-second “on” period followed by a 50-second “off” or rest period, with a recommended treatment time of 10 minutes per stimulation session. 1.
What is medium frequency current?
Medium frequency currents are the currents whose frequency falls between the range of 1000 to 10,000 Hz. They are being used therapeutically due to their advantage of greater penetration and with a higher tolerance and comfort over the low frequency current.
What is UHF therapy?
UHF-therapy is a method of electrotherapy, based on the effect on the patient’s body of a predominantly ultrahigh-frequency electromagnetic field. For the treatment of used wooden furniture. During the procedure, the patient is in a sitting or lying position. The duration of UHF-therapy is 10-15 minutes.
What are the three types of current?
There are three basic waveforms used in commercial therapeutic electrical stimulation units: direct current, alternating current, and pulsed current.
What is FG test?
Blood found in gastric contents may be used for early detection of conditions such as gastritis, ulcers or cancer. The HemaPrompt FG test is based on the oxidation of phenolic compounds present in guaiac to quinones, resulting in the production of a blue color.
What is SD curve?
Strength duration curve is a graph between electrical stimuli of different intensities and recording the time needed by each stimulus to start the response. S-D curve should be plotted after 20th day of injury/lesion. S-D curve should be plotted after 20th day of injury/lesion.
What is MF frequency band?
Medium Frequency (MF): 300-3000 kHz Because medium frequencies afford stable transmission of radio waves over long distances, they are used primarily for medium wave broadcasting (AM radio), ship communications, LORAN (radio navigation), and other applications.
What is MF band?
Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz). Part of this band is the medium wave (MW) AM broadcast band. The MF band is also known as the hectometer band as the wavelengths range from ten to one hectometer (1000 to 100 m).
What effect does UHF therapy have?
The ultrahigh therapy has the anti-inflammatory effect, stimulates blood circulation, decreases the edema and reduces pain sensations of the patient. Thanks to such wide range of impact, UHF is prescribed for the most different diseases: respiratory system (bronchitis, pleuritic, pneumonia, bronchial asthma);
What is physical factor of UHF therapy?
UHF therapy has a physiological and therapeutic effect. Irradiation leads to reflectory and neurohumoral reaction. This causes the dilatation of blood vessels, increases the number of functional capillaries, increases blood circulation and lymph flow, has anti-resorption effects.
Which current is used in home?
Alternating current (AC)
Alternating current (AC) electricity is the category of electricity usually used in homes and businesses.
What is Rd test in electrotherapy?
Therefore, stimulation should not be applied over the abdominal area during pregnancy. TRADITIONAL CLINICAL ELECTRICAL EVALUATION TESTS. 1. Reaction of Degeneration Test. The reaction of degeneration (RD) test is a useful screening procedure for assessment of problems that may involve lower motor neurons.
What is chronaxie and rheobase?
Chronaxie is the minimum time required for an electric current double the strength of the rheobase to stimulate a muscle or a neuron. Rheobase is the lowest intensity with indefinite pulse duration which just stimulated muscles or nerves.
What is VHF MF HF?
Digital selective calling or DSC is a standard for transmitting pre-defined digital messages via the medium-frequency (MF), high-frequency (HF) and very-high-frequency (VHF) maritime radio systems. It is a core part of the Global Maritime Distress Safety System (GMDSS).
What is MF in ship?
MF Ship Prefix Abbreviation. 1. MF. Motor Ferry. Ship Name, Ship, Sea.
