2. MEDICAL BACKGROUND

NMES
5
NMES (NeuroMuscular Electrical Stimulation) is used successfully both in medical rehabilitation and as
a complement to athletic training on all levels.
The goal of electrical muscle stimulation is to achieve contractions or vibrations in the muscles. Normal
muscular activity is controlled by the central and peripheral nervous systems, which transmit electrical
signals to the muscles. NMES works similarly but uses an external source (the stimulator) with elec-
trodes attached to the skin for transmitting electrical impulses into the body. The impulses stimulate
the nerves to send signals to a specifically targeted muscle, which reacts by contracting, just as it does
with normal muscular activity.
Electrical muscle stimulation is suitable for all the muscles in the body. It can be used to strengthen
muscles weakened by surgery, a fracture, etc., and improve mobility. It is also an excellent tool for
stroke rehabilitation, helping patients in handgrip and gait training.
Electrical muscle stimulation for rehabilitation purposes should be tried out individually by a physio-
therapist or other caregiver for the best results.
TENS
TENS (Transcutaneous Electrical Nerve Stimulation) gives good results in acute and chronic pain condi-
tions of many kinds. It is clinically proven and used daily by physiotherapists, other caregivers and top
athletes around the world.
High-frequency TENS activates the pain-inhibiting mechanisms of the nervous system. Electrical
impulses from electrodes, placed on the skin over or near the painful area, stimulate the nerves to
block the pain signals to the brain, and the pain is not perceived. Low-frequency TENS stimulates the
release of endorphins, the body's natural painkillers.
TENS is a safe treatment method and has, in contrast to drugs and other pain relief methods, no side
effects. It may be sufficient as the only treatment form, but it is also a valuable complement to other
pharmacological and/or physical treatments. TENS does not always treat the cause of pain. Consult
your doctor if pain persists.
