This particular type of current is called interferenziale It s whythe shape and interferes with the tissues in the points in which the two different medium frequency current fields intersect.
The interferential current is a sinusoidal alternating current at medium frequency (2500 Hz – 4000 Hz – 10000 Hz), amplitude modulated, It characterized by a high capacity for tissue penetration and an excellent tolerability also on the part of particularly sensitive patients.
The analgesic action of 'interferenziale bipolar, with modulation frequency between 0 e 200 Hz, It is fed back to the gate control mechanism, to stimulation of inhibitory mechanism, the peripheral block transmission of pain, to the removal of substances from the affected region algogenic, as for the current TENS .
By varying the modulation frequency used, It can also exploit a excitomotor effect, contributing, activating the “muscle pump”, the return of the venous flow.
clinical Applications
the runs
all interference It is particularly suitable for Osteoarthritis deep joints (anca, lumbar spine), toI Katie deep and per hypotrophy normally innervated muscle and deep muscles.
The interferential current is used in the field of physiotherapy for the purpose excitomotor and analgesic.
therapeutic effects
excitomotor Effect: causes contraction of the normally innervated and deep muscles.
Analgesia: could cause vasodilation which, through the increase of the local blood flow, rimuoverebb substances from the tissues algogenic.
It is applied in the treatment of the following pathologies:
deep Osteoarthritis (anca, lumbar and cervical spine)
deep tendinopathies: hip and shoulder tendinitis
