3.4 Pulse intensity
Setting the degree of intensity is individually de-
pendent on the subjective feeling of each individual
user and is determined by a number of parameters
such as application site, skin circulation, skin thick-
ness as well as quality of electrode contact. The actual setting should
be effective but should never produce any unpleasant sensations such
as pain at the site of application. While a slight tingling sensation in-
dicates sufficient stimulation energy, any setting which leads to pain
must be avoided.
With prolonged application, readjustment may be necessary due to
time adjustment processes at the site of application.
3.5 Cycle-controlled pulse parameter variation
In many cases it is necessary to cover the entirety of tissue structures
at the site of application by using several pulse parameters. With the
Digital EMS/TENS unit, this is done by the existing programmes auto-
matically making a cyclical pulse parameter change. This also prevents
individual muscle groups at the site of application from getting tired.
With the Digital EMS/TENS unit there are useful presettings for current
para meters. With this, you can change the impulse intensity at any time
during use. For 6 programs you can also set various parameters for
stimulation yourself.
