1.6 Information on high & low-frequency therapy
What is frequency?
Frequency is the number of times electric stimulation is
applied to the body per second and is represented by a unit
called Hertz (Hz).
I. What is Low Frequency?
Although we do not notice it, our bodies generate very weak
electricity from various parts of the body including the brain,
heart, muscles, and nerves. This electricity is called bioelec-
tricity. The bioelectricity plays an essential role for the normal
functioning of our bodies. Our bodies sensitively react to elec-
tric stimulation applied from the outside and cause various
changes. The method to treat abnormality of bioelectricity,
which is manifested as stiffness or pain, by effectively using
the above mentioned action is called electrotherapy of which
low-frequency therapy is typical.
Effects of low frequency stimulation
Low-frequency stimulation is effective in relieving symptoms
of chronic pain, stiffness and numbness. It is said to have the
effects to activate secretion of pain surpressing substances or
to improve the blood circulation.
Mechanism of low-frequency electrotherapy
- Pumping action of muscles -
Muscles contract and relax with the flow of the low-frequency
current. When the muscle relaxes, a large amount of blood
flows in, and when the muscle contracts, the blood containing
wastes is pumped out. With repeated actions, the blood flows
smoother and the blood circulation is improved.
Shutting out pain signal
When low-frequency current flows to the region experiencing
pain, it acts on the transmission mechanism of pain.
Thus low-frequency current is said to reduce the transmission
of pain to the brain.
II. What is High Frequency?
- as used for the “Quick Relief” function -
High frequency stimulation is effective for acute (nerve) pain
and is said to be especially useful in the immediate blockage
of pain transmission compared to low-frequency stimulation.
Standard treatment time
Long-time treatment and strong stimulation may cause mus-
cular fatigue and may generate adverse effects. In order to
avoid excessive treatment, this model is made to turn off the
power automatically after 15 minutes.
