Interferential Therapy first appeared in the mid 1950's.
Originally developed in Europe by Dr. Hans Nemec of Vienna,
Austria.
The name Interferential Therapy stems from the concept
of two currents "Interfering with each other",
readily apparent when one views the four electrodes that
are necessary to produce the standard interferential effect
in a patient.
As it shares much in common with other forms of electotherapy,
it has a number of advantages available for the treatment
of patients, mainly the ability to facilitate healing
of damaged tissues, using a bio-electrical effect.
Indications for use of Interferential
Therapy include reduction of muscle spasm by repeated contraction
and relaxation of the muscle which fatigues the musle and
promotes relaxation, interrupting the pain-spasm-pain cycle.
Increasing local blood circulation
by contracting muscles and creating muscle pumping,
supplying circulatory nutrients to muscles and carrying
away metabolic waste products.
Maintaining or increasing range
of motion by contracting muscles to move a joint
through its' normal range of flexing and extending,
improving muscle function and flexability.
Re-educating muscles by stimulating motor
nerves and contracting muscles, replicating volitional
activity, re-learning normal muscle movement and
control. |
