This particular type of currents is called Interferential why sthe shape and interferes with the tissue in places where the fields of two different medium frequency currents intersect.
The Interferential current is a medium-frequency alternating sinusoidal current (2500 Hz – 4000 Hz-10000 Hz), amplitude modulated, characterized by a high capacity of penetration into the tissues and by an excellent tolerability, even by the sensitive patients.
The analgesic effect ofInterferential bipolar, with modulating frequency between 0 and 200 Hz, is brought back to the gate control mechanism, the stimulation of peripheral pain inhibitory mechanism, blocking transmission, removal of substances from the affected region, as for current algesic TENS.
By varying the modulation frequency used, you can also use a motor exciting effect, which contributes, by activating the "muscle pump", the return of venous flow.
The Interferential current is used in physiotherapy field motor exciting purposes and pain relief.
Motor exciting effect: causes the contraction of the muscles normally innervated.
Analgesia: may cause vasodilatation which, by increasing local blood flow, rimuoverebbe from fabrics algesic substances.
Is applied in the treatment of the following diseases:
Osteoarthritis (hip, lumbar and cervical spine)
Tendonitis: Tendonitis hip and shoulder
