• Furthermore, it can be assumed that the electrical stimu-
lation also stimulates blood flow. Muscles contract upon
contact with electrical stimulation and then expand. The
repeated contracting and relaxing causes the blood to flow
in and out, improving circulation.
How does EMS work?
The EMS device sends soothing pulses through the skin and
stimulates the nerves in the area being treated. When the
muscle receives this signal, it contracts as if the brain had sent
the signal itself. As the strength of the signal increases, the
muscle contracts in the same way as it does during exercise. If
the signal is interrupted, the muscle relaxes and the process
repeats. The goal of electrical muscle stimulation is contraction
or vibration in the muscles. Normal muscle activity is controlled
by the central and peripheral nervous system, which sends
electrical signals to the muscles. The EMS functions in a similar
way, but it uses an external source (stimulator) in combination
with electrodes placed on the skin to conduct the electrical
pulses into the body. The pulses stimulate the nerves so that
they send targeted signals to specific muscles, which then re-
act by contracting – just like during normal muscle activity.

General safety information
− If there is a defect, you must not repair, modify
(change) or use the TENS/EMS device. When
used incorrectly, the stimulation current can
lead to pain, injury or burns.
