INSTRUCTIONS FOR USE - TENStem eco basic
• A slight, non-persistent reddening of the skin following stimulation in the area of the elec-
trodes is normal, as blood circulation is stimulated by the TENS application.
• If prolonged redness, burning, itching or skin blisters should occur under the electrodes
or around the electrode site following stimulation, you must consult the doctor before
further TENS application.
1.5.2 Possible side eects of muscle stimulation
• Muscle pain: Muscle pain similar to muscle soreness can occur if muscle stimulation is too
intense and extensive. Avoid this by using shorter and less intense stimulation, especially
during the rst treatments.
• Muscle cramps with possible damage to the muscle and neighbouring muscle structures
such as connective tissue, ligaments, tendons and bones
• Muscular overload reactions with
– Muscle pain that may last for several days
– Muscle weakness that may last for several days
– The release of muscle enzymes and muscle proteins as well as electrolyte imbalances
due to muscle strain and muscle breakdown (rhabdomyolysis) can in very rare cases
(especially with undetected pre-existing conditions/overtraining) result in strain and
damage to internal organs such as the kidneys, liver and heart.
• The consequences of long-term electrical muscle stimulation (for more than six weeks at a
time) are not known, so negative long-term eects cannot be ruled out. We are not aware
of any such cases when using our products.
