What is physiotherapy:
The real role of physiotherapy is a valuable help for recovery, including techniques not at all insignificant. Physical therapy includes all therapeutic applications based on the use of physical agents. Here we include magnetic waves, mechanical waves, cryo-thermotherapy, especially electrical currents.
Types of electrical currents used in physical therapy:
Direct current (DC): also called galvanic current; a direct current is a current whose intensity is always constant. Its direct effects on the body is the heat ; analgesics at the positive pole and hyperexcitability at the negative pole. Under the influence of an electric current, positive ions are placed in the area where the electrodes will be drawn toward the negative electrode (cathode), while negative ones will be attracted to the positive electrode (anode). Galvanic current is used mostly for drug ionization (iontophoresis), resulting in the introduction of pharmacologically active substances in the area we wish to treat. Pain medications can be used – inflammatory, fibrinolytics, vasodilators, muscle relaxants, anti-edematous etc, depending on the effect we’re expecting. Galvanic baths are another interesting application of DC (direct current) . These include the immersion of upper and / or lower limbs in tanks filled with water, connected to a DC generator. This way, the entire body can benefit from this type of current.
Variable currents: we distinguish several types of such currents, depending on their frequency – currents of low frequency (<1000 Hz). Based on the current form, they can have properties excito-motor ( rectangular, exponential, Farad current ) and analgesics (diadynamic, TENS); medium frequency currents (1000-10000 Hz). Can have excito-motor effects (weaker than those of low frequency currents) and analgesics (interferential current); high frequency (> 100,000 Hz)- known as pulsed or continuous shortwave and microwave (exert thermal effects on the surface or in depth).
When is not indicated phisiotherapy using electrical currents :
In general electric currents are very well tolerated. But there are situations when you have contraindication. These include: the use of high amplitudes in pregnant women and patients with cardiorespiratory disorders;epilepsy;pathophysiological disorders associated and sensitivity disorders, coma, patients with psychiatric disorders;allergies to substances used for ionization;circulatory disorders when using galvanic current.
