1.1 What is Low Frequency?

A treatment method effectively using the physiological
action
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.

1.2 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 contain-
ing wastes is pumped out. With repeated actions, the blood
flows smoother and the blood circulation is improved.
