8.11 Electric current parameters
Electrostimulation devices operate with the following electric current settings,
which may a ect the stimulation results di erently, depending on the setting:
Pulse shape
This describes the time function of the stimulating cur-
rent.
A distinction is made between monophasic and biphasic
pulse currents. In monophasic pulse currents the current
flows in one direction, and in biphasic pulse currents the
electrical pulse alternates its direction.
The Digital TENS/EMS device only provides biphasic
pulse currents as these relieve muscles, cause little muscle fatigue and o er
safer use.
Pulse frequency
The frequency indicates the number of individual pulses
per second and is displayed in Hz (Hertz). It can be calcu-
lated by determining the cyclic value for the time period.
The relevant frequency determines which types of muscle fibres react most
favourably. Slow-reaction fibres react more easily to lower pulse frequencies
of up to 15 Hz, whereas rapid-reaction fibres only respond from approximately
35 Hz up. Pulses of approx. 45–70 Hz are linked with constant tension in the
muscles and quicker fatigue. Higher pulse frequencies are therefore better to
use for speed strength and maximum power training.
Pulse width
This indicates the duration of an individual pulse in micro-
seconds. Among other aspects, the pulse width therefore
determines the penetration depth of the electricity, where
usually larger muscle mass requires a larger pulse width.
Pulse intensity
Adjusting the intensity level depends on the individual
sensitivity of each user and is determined by a variety
of variables, such as site of application, blood supply to
the skin, skin thickness and the quality of the electrode
contact. The settings should be e ective but should never cause an unpleasant
sensation, such as pain at the site of application. While a gentle tingling indi-

cates su cient stimulation energy levels, any setting that causes pain should
be avoided.
If using the device over an extended period, you may need to adjust the inten-
sity level as your muscles start to adapt to the pulse intensity.
Cycled pulse parameter variation
In many cases it is necessary to cover the overall tissue structure at the site
of application by applying several pulse parameters. In the Digital TENS/EMS
device, this is achieved by the provided programs, which automatically make a
cyclical pulse parameter change. This also prevents individual muscle groups
at the site of application being a ected by fatigue.
Time
The Digital TENS/EMS device provides useful preset current parameters. You
can change the pulse intensity at any time during use. In 6 programs you can
also set various parameters for stimulation yourself.
9. CLEANING AND MAINTENANCE
Adhesive electrodes
• To ensure that the adhesive electrodes remain adhesive for as long as pos-
sible, clean them carefully with a damp, lint-free cloth or clean the under-
side of the electrodes under lukewarm running water and pat dry with a
lint-free cloth.
Before cleaning with water, remove the connection cables from the elec-
trodes.
• Following treatment, stick the electrodes back onto the carrier foil.
Cleaning the device
• Always remove the batteries from the device before cleaning.
• The number of uses possible depends on the environmental conditions and
skin qualities. If the electrodes no longer adhere to the skin properly during
use, please replace them.
• Clean the device after use with a soft, slightly damp cloth. If it is very dirty,
you can also moisten the cloth with a mild soapy solution.
• Do not use any chemical or abrasive cleaning agents for cleaning.
Ensure that no water enters the device.
